What Is Ventilation Required For?

There is a range of aspects to determine air quality.

Oxygen and Carbon Dioxide Concentration. Oxygen decrease and carbon

dioxide increase cause stuffiness in the premises.

Content of Harmful Substances and Dust. High content of dust, tobacco

smoke and other substances in the air badly impact human organism and can

cause various lung and skin diseases.

Odours. Bad smell causes discomfort or irritates nervous system.

Air Humidity. Increased or decreased moisture cause discomfort and even

can result in acute attacks of disease for sick people. Air humidity is important also

for the atmosphere in the premises. For instance, doors, window frames, furniture

may dry up of decreased humidity in winter; but they may expand in the premises

with increased humidity level like swimming-pools, bathrooms etc.

Air Temperature. A person feels good in a premise with the temperature

21-23°C. Temperature variation causes the change of comfort feeling that

influences a person’s physical and mental activity.

Air Motion. Increased air speed in the premises causes the feeling of draft,

and decreased speed causes air blanketing. We feel the impact of any of these

factors.

Solution:

Any ventilation system must include simultaneous fresh air supply and extract

air exhaust thus ensuring the ideal air balance in the room. In case of poor or

insufficient air intake from outside the oxygen content decreases and humidity

and dustiness level in the room increases. If exhaust ventilation is not provided

or it is not effective, polluted air, smells, humidity and harmful substances are

not removed. Furthermore, exhaust ventilation is not effective without supply

ventilation and none of these systems can operate independently. It is impossible

to arrange correct air exhaust from a closed vessel because removed air is not

compensated. Supply ventilation in a closed vessel system is not effective either.

Some objections can be raised with the example of an exhaust fan in the bathroom

or in the kitchen. Once it runs, the ventilation system operates. Really. It looks

like it operates. However such ventilation example shows that after extract air

is removed by the fan the flat is filled with non-arranged air flows from various

slots in the windows, doors and other building structures. Consequently dust

and odours are transported with the air flows from outside and air draught can

appear. Opened windows and doors are another way for air supply. Such way of

ventilation arranging is possible but it has some problems like abrupt temperature

lowering of the heated premises during winter time, dust and noise from outside,

insects invasion through the opened windows, draughts and sharp temperature

drop. Correct ventilation system is the only solution in this situation. Ven-

tilation system ensures filtered air supply during summer time and filtered

and heated air supply during winter time as well as removal of polluted

extract air from the premises. The joint application of supply ventilation

units to supply fresh air to the rooms jointly with exhaust fans provides

quality ventilation in your buildings.

VENTILATION

IN OUR LIFE

We are surrounded by air and breathe

in and out 20 000 litres of air every day.

How much inspired air is applicable for

the healthy life?

The issue of ventilation is the most essential subject from the point

of view of thermal energy saving permanent temperature maintain-

ing. The factors that influence the heat loss dynamics vary from wall

thermal protection to heaters and heating system quality, density of

wall panels joints and window joints as well as personal consumption

habits.

Ventilation demands up to 45% of the total heat energy consump-

tion in modern buildings. The reasons are as follows:

a) One half of air volume is exchanged through the open window

within 30-60 min. So the heat losses gorw tremendously;

b) Energy saving houses are equipped with all available facilities for

sealing and thermal insulation of the buildings. Such houses are so well

insulated that the heat loss share through the walls makes only 30 to

40% of the total amount.

Thus the ventilation induced heat losses remove 2/3 of the total

heat.

So we come to the point of providing air exchange with minimum

heat losses. From 30% to 70% of heat loss is variously estimated for

the exhaust ventilation that is traditionally for residential houses. The

controllable air exchange and heat recovery are the compulsory at-

tributes in the modern house construction that are ensured by means

of air handling units. The forced ventilation allows recuperating up to

90% of the exhaust air heat. Such effect is attained due to installa-

tion of the heat exchanger (recuperator). The heat exchanger allows

saving heat in winter period and contributes to better operation of air

conditioners jointly with ventilation in summer period. In addition the

heat exchangers have heat- and soundinsulated casing that reduces the

noise level produced by equipment in the room. As of today the ventila-

tion systems based on heat exchangers are the most state-of-the-art

and progressive solution for air exchange arranging in the premises.

Due to recuperation of the unit its owner can save good money for

operation costs. Use of the ventilation units with heat recovery jointly

with the air conditioning systems is not only the most effective way to

arrange the required microclimate in the room but to cut costs as well.

In winter the heat exchanger saves heat and in summer it saves cool.

The plate heat exchanger of cross-flow or counter-flow type is the

simpliest one as it contains no movable parts and electrical connec-

tions; it separates the air streams fully; requires no additional energy

consumption and maintenance.

Use of units with heat recovery in ventilation systems results in

shortening of payback period and improving its ecological characteris-

tics in view of low energy consumption, low investment for heat energy

generation and its distribution, careful attitude to environment.

New series of compact air handling units with EC (electronically

commutated) motors provide energy consumption reducing up to 50%

as compared to traditional asynchronous motors. Operating costs will

be generally reduced by 30%.

Fans with EC motors have the following advantages:

- efficient operation at any rotation speed of fan impeller (up to

zero) and significant winding electrical resistance;

- low heat generation that enables reducing performance losses

of refrigeration equipment and compensate for heat generation of

fan motors in case of use of EC-motor fans in conditioning systems;

- fan overall dimensions can be reduced in case of external rotor

and EC-motor design. Consequently the disadvantages related to

large-scale overall dimensions that are typical for fans with stan-

dard motors are minimized;

- the maximum motor speed does not depend upon frequency

(operation both at 50 Hz and 60 Hz is possible);

- high efficiency at low speed;

- external rotor design makes it compact.

EC motors with external rotor

EC motor with external rotor is the innovative development of EBM-PAPST company

with the electronics integrated directly into the motor. The built-in electronics

ensures the full control over the energy consumption and speed rate and provides

smooth regulation and keeping of the fan parameters. Standard fans require

additional control equipment to have the similar functions. EC motors have the

energy consumption by 50% less as compared to standard models. The operating

costs for EC motors maintenance are also generally by 30% less. Premium efficiency

of EC motors reaching up to 90% is their great advantage.

Basic principle of EC motors:

- The permanent magnets integrated into the motor create magnetic field. The

above phenomena disables any thermal losses in the rotor which are common

with any squirrel-cage motor.

- change of the current direction in the stator winding is effected by means of

the integrated commutating electronics based on Hall sensor (controller) which at

any moment calculates and supplies to the stator the required for the continuous

rotor rotation polarity. Such motor design does not need any brushes requiring

regular maintenance.

- EC motors are suitable for

connection to direct-current

voltage according to the required

parameters or through the switching

module directly to AC supply (230,

400 V, 50/60 Hz).

High-powered EC motors produce

low noise level which makes their

application suitable in supermarkets,

hotels and other public facilities as

well as in residential premises.

EC systems are featured with long

service life and are designed for at least 4.5 years of continuous operation,

i.e. about 40 000 operating hours. In one line with that service maintenance is

minimized because of high reliability.

Due to a complex of considerable advantages the fans equipped with EC motors

ensure quick pay off period for owners and investors.

MOTOR DESCRIPTION AND PRINCIPLE

Fan types:

Various fan types are applied in air handling units for air transportation through air

ducts, direct air supply or air exhaust.

Centrifugal fans consist of two basic components - turbine and scroll casing.

Impeller of centrifugal fan is a hollow cylinder with mounted blades inside,

circumferentially fixed with disk plates. The hub for mounting the impeller

on the shaft is located at the center of the

strengthening ring.

During the impeller operation air is trapped

between the blades and moves radially from

the center compressed. Under centrifugal force

air is transported to the scroll casing and then

moved to the exhaust pipe.

Centrifugal fans incorporate forward- or

backward-curved blades. Use of centrifugal

impellers with backward-curved blades allows

up to 20% energy saving. Another important privilege of backward-curved blades

is their high air overload capability.

Centrifugal fans with forward-curved blades

ensure the same air capacity and pressure

characteristics as the backward-curved blades

do but they require smaller impeller diameter

and lower speed. So they are able to attain

the required result demanding less space and

producing less noise.

External rotor motors

External rotor motor design is similar to asynchronous motor design but the motor

rotor is located outside of the stator winding and the stator with the windings is

located in the motor centre. Such original modification ensures the compact size of

the unit. The motor shaft rotates on the ball bearings mounted inside the stator. The

impeller is fixed on the rotor casing. Such design provides air cooling of the electric

motor which allows using the fans in the wide temperature range. All the motors

and impellers are statically and dynamically balanced at the manufacturing facility.

EC motor advantages

COMPACT SIZE

- the systems based on EC motors provide the required operating

parameters by smaller fans due to their increased efficiency. Actually the

fans have the minimum size.

LOW ENERFY CONSUMPTION

- premium efficiency of the motor reaching up to 90% provides reducing

energy consumption at least by 30% for the same operating point

without speed control. In case of speed control the energy consumption

is by 2-8 times less!

SMOOTH AND ACCURATE SPEED CONTROL

- the fans are programmable and change the air capacity depending on

any control parameter like temperature, humidity, pressure, air quality

etc. Depending on a setting the EC motors change their rotation speed

respectively to a control parameter change and air is supplied in the

required for the system volume.

HIGH AUTOMATION DEGREE OF CONTROL PROCESS

- high automation degree of control process reduces the influence of

human factor.

INTEGRATED MOTOR PROTECTION

- prevents rotor locking, electrical and temperature overloads that

extends the equipment service life due to its resistance to change of

voltage.

FULL CONTROL

- fan operation can be controlled at any place of the Earth through

Internet.

WIDE RANGE OF SUPPLY VOLTAGE

- 200-277 V of 380-480 V ±15%.

MINIMUM CROSS SECTION OF POWER CABLE AND POWER

TRANSFORMER OUTPUT

- the fans have no startup currents and for that reason they consume

much less energy as compared to the standard fans.

MINIMUM MAINTENANCE

- long-term service life (as compared to AC).

VENTILATION WITH HEAT RECOVERY

The design of the plate heat exchangers is such as to exclude transfer of

contaminants, odours and microbes from exhaust air flow to supply air flow. The

air flows are divided by wall elements of heat exchanger plates made of aluminium

or polystyrene. Thermal energy quantity that is transferred from exhaust air to

supply air depends exclusively on thermal conductivity of the applied materials and

temperature difference between two flows. So warm exhaust air is warmed up

and cold intake air is heated down.

Though moisture from warm air flow is not transferred to cold air flow, a part of

the latent heat energy from humid exhaust air is used for heat recovery. At low

outside temperatures and high exhaust air heating degree the exhaust air can be

cooled to the temperature of dew point. Consequently it produces the condensed

moisture and the latent vaporization heat is released. During this process the

temperature difference of the air flows that cross the heat exchanger is more

than that one during no condensing and that means higher total thermal energy

and consequently higher heat recovery efficiency. That is why it is so important to

provide free condensate drainage from the heat exchanger.

Use of plate heat exchangers in ventilation system results in shorter payback

period and better ecological characteristics ensuring the further advantages:

- low energy consumption;

- low investment for thermal energy generation and its distribution;

- no removable parts which means durability and long service life at continuous

operation;

- high-efficient heat recovery and little investment result in high self-repayment;

- environmental protection.

Сontrollable air exchange and heat recovery are the compulsory attributes in the modern construction that are ensured by means of air handling units. The forced

ventilation allows recuperating up to 90% of the exhaust air heat. Such effect is attained due to installation of the heat exchanger (recuperator).

The plate heat exchangers of cross-flow or counter-flow type are used for heat recovery in Vents VUT ventilation units. The exhaust air in the heat exchanger transfers

the heat energy to the supply air.

Design and operating principle of air handling units based on VUT-600 WH EC example.

VUT-600 WH EC unit operates as follows:

Fresh cold air from outside is supplied to VUT WH EC unit through the air ducts, gets filtered and passes further through the heat exchanger from where it is supplied

to premises by means of the supply fan. Warm exhaust air from premises goes back to VUT WH EC unit through the ducts where it gets filtered, then passes again

through the heat exchanger and is exhausted outside by means of the exhaust fan. The exchange of heat energy of the warm contaminated air from the premises

with the fresh cold air from outside takes place in the heat exchanger. That reduces heat losses and consequently cuts the heating costs in winter time.

Recuperation economic analysis:

Air capacity: 500 m3/h

t1 – intake temperature;

t2 – outside temperature (-10 oС);

t3 – internal temperature (+22 oС).

Recuperation efficiency is calculated as follows: Kef = 60%

Air temperature after heat exchanger:

t1= t2+ Cef (t3 –t2) = (-10) + 0,60 (22-(-10)) = 9,2 oC

To heat the air temperature up to the temperature 19,2 oС (-10 up to 9,2 oС)

the required energy consumption is:

Р(Wt) = L(m3/h) x 0,34 x t(oС) = 500 m3/h х 0,34 х 19,2 = 3264 W

SUPPLY UNITS

Description

Air supply MPA unit is a complete ventilation unit

for air filtration, air heating and supply to premises.

Compatible with 400х200, 500х250, 500х300,

600х300, 600х350 and 800х500 mm rectangular

air ducts.

Casing

Steel casing covered with aluzink coating internally filled

with 25 mm heat- and sound-insulating layer made of

mineral wool.

Filter

Integrated panel G4 filter ensures sufficient supply

air purification.

Heater

Both electric heater (MPA...E models) and water/

glycol heating coils (MPA...W models) are used for

heating of supply air during winter and off-season

period. Tubular heating elements of the electric fan

heater are ribbed to increase the heat exchange surface

area and heat transfer to supply air. The water heaters

are designed for max. operating pressure 1.0 MPa

(10 bar) and max. operating temperature 95 оC of the

heat medium.

Fan

Centrifugal double-inlet fan with forward-curved

blades and built-in overheating protection with

automatic restart. The fan motor and impeller are

dynamically balanced in two planes. The ball bearings

in the electric motor are maintenance free and

designed for at least 40000 hours operation.

Control and automation

Two options for supply unit modifications are possible:

1. No control. Customer-defined and customer-

selected automation system.

2. Integrated control and automation system for

three-speed (air capacity) control and setting supply

air temperature. The unit may be controlled from the

external control panel fixed on 10 m wire delivered as

a standard.

MPA...E control and protection functions

switching the unit on/off from the control panel;

setting the supply air temperature from the remote

Supply units with the air capacity up to 3500 m3/h in the compact sound- and heat-insulated casing

with electric heater

schedule;

overheating protection of the electric heating

elements;

disabling electric heater operation when the fans

are not running;

electric heater overheating protection by two

overheating thermostats, one thermostat activated

at 50°C with automatic reset and another thermostat

activated at 90°C with automatic reset;

actuating the air damper (refer RRVA);

input for alarm fire fighting signal;

input from external humidity sensor, CO2 sensor,

etc (normally opened dry contact). On sensor’s

output signal the unit switches to the maximum

speed.

MPA...W control and protection functions

switching the unit motor on/off;

three-speed fan selection;

maintaining set supply air temperature by means

of controlling the circulating pump and heat medium

regulating valve;

water heater freezing protection by the tempe-

rature sensor at outlet from the heating coils and the

return heat medium temperature sensor;

control and regulation of the external circulation

pump installed at the heat medium supply line to the

water heater (mixing unit pump);

control of the compressor and condensing unit of

the water cooler by the room temperature sensor

(for the models equipped with a duct air cooler);

supply fan control and regulation;

filter clogging control;

actuating the external air damper with a return

spring;

unit shut down at signal from the fire alarm system.

The mixing units USWK are recommended for

smooth supply air temperature regulation in the

units equipped with water heaters. The mixing unit

USWK with three-way heat medium regulating

valve and circulation pump provides smooth heating

capacity regulation and minimizes the water heater

freezing danger.

Mounting

The supply unit can be mounted on the floor,

suspended to the ceiling by means of a seat angle

with a flexible connector or fixed to the wall using

brackets. The unit can be installed either in such

service spaces as balcony, storeroom, basement,

roof space or in main premises above the suspended

ceiling, in the pocket or placed directly in the room.

The unit can be mounted in any position but the

vertical one with air downstream because the

heating elements are not allowed under the fan.

Access for the unit maintenance and filter cleaning

shall be provided.

Air supply and exhaust ventilation in the modern office can be arranged

as follows. Air handing MPA unit, exhaust fan complying with MPA unit

characteristics, intake and exhaust main air ducts are mounted in the hall

behind the suspended ceiling. The branchings are laid into the office premises

and air distribution units. Intake air from outside flows through the external

grille, is filtered in the air handling unit, heated to the required temperature

and supplied to the office rooms through the branch duct system. Exhaust air

is extracted outside through the external grille by means of the exhaust fan.

Thus the office has the permanent fresh air supply, controllable air exchange,

no draughts when opened windows, no dust and no noise.

The unit is designed for indoor installation either on

the floor, on the wall or under the ceiling by means

of a seat angle with inserted vibration-damping

element or attached to a wall with brackets. The

unit can be mounted either in service spaces or in

main premises above the suspended ceiling, in the

pocket or the unit can be placed directly in the room.

All the electrical connections are performed through

the terminal box placed in the connection box. PA

supply units are supplied with the fastening brackets

to facilitate mounting. The unit can be mounted

in any position but the vertical one with vertical air

downstream because the electrical heating elements

are not allowed under the fan. Access for the unit

maintenance and filter cleaning shall be provided. The

PA…W unit design enables to lead the water heater

pipes to the right or to the left while mounting. The

pipes are directed on the right on supply air side by

default.

Control and automation

The supply units are available in two modifications:

1. No control and automation system supplied.

Customer-defined and customer-selected control

automation system.

2. Integrated control and automation system for

speed (air capacity) control and setting supply air

temperature. The unit may be remotely controlled

from the external control panel fixed on wire.

unit on/off, fan speed selection (low/medium/

high speed), selecting heating/cooling modes (if

connected to duct heater);

maintaining supply air temperature set from the

control panel by smooth heating capacity control;

smooth frequency speed control of the fan;

Supplementary equipment

The mixing units USWK are recommended for

smooth supply air temperature regulation in the

units equipped with water heaters. The mixing unit

USWK with three-way heat medium regulating

valve and circulation pump provides smooth heating

capacity regulation and minimizes the water heater

freezing danger. To disable uncontrollable air flow

when the fan is off it is recommended to install

the air damper with servo actuator (refer RRVA)

from outside at the unit inlet. To protect the water

heater against cold intake air in case of power

failure for the units with water heaters (PA…W)

it is recommended to install the air damper with

a return spring (refer RRVAF). For attenuation of

sound generated by the fan it is recommended to

install the duct silencer (refer SR). For vibration

absorbing it is recommended to install the flexible

anti-vibration connectors (refer VVG) on both sides

of the unit.

VENTS VUT H mini

Description

Air handling units VUT (H) mini are the complete

ventilation units designed for air filtration, heating

and supply to the premises and removal of exhaust

air. The heat of the exhausted air is transferred to the

supply air through the plate heat exchanger. All the

models are compatible with 100 and 125 mm round

ducts.

Modifications

VUT V mini – the models with vertical duct

connections, fans with AC motors.

VUT H mini – the models with horizontal duct

connections, fans with AC motors.

Casing

The casing is made of aluzink with 20 mm mineral

wool internal heat and sound insulation.

Filter

Two G4 built-in filters ensure supply and exhaust air

fiiltration.

Fans

The unit is equipped with supply and exhaust

centrifugal fans with backward curved blades and

built-in thermal overheating protection with automatic

restart. The electric motors and the impellers are

dynamically balanced in two planes.

Heat exchanger

The plate heat exchanger is made of aluminium

plates. Whenever heat recovery is not required for

unit operation the heat exchanger block can be

easily replaced by a “summer” block. The unit is also

equipped with the drain pan for condensate drainage

as well as with built-in icing protecting system. During

operation of the heat exchanger in the winter time

the heat from the warm exhaust air is transferred

to the cold supply air. During extract air heat energy

extraction some condsensate can be generated.

If the temperature of the intake air is below -5 °С

the condensate can get frozen. To prevent the heat

exchanger freezing electronic protection system

is applied. It switches the supply fan off as the

temperature sensor requires. Warm extract air

defrosts the heat exchanger, then the supply fan

switches on and the unit continues operating under

rated conditions.

Control

Switching the unit on and its capacity control is

performed with thyristor speed controller (RS-1-400)

which provides smooth motor speed control over the

range of 0-100%.

Mounting

Air handling unit is mounted on the floor and

suspended to the ceiling by means of a seat angle

with inserted vibration-damping element or attached

to a wall with brackets. The unit can be mounted

either in service spaces or in main premises above

the suspended ceiling, in the pocket or the unit can

be placed directly in the room. Mounting position

shall provide correct condensate drainage. Access for

maintenance and filter cleaning shall be reserved on

the side of the removable side panel on the left from

supply air side.

AIR HANDLING UNITS WITH HEAT RECOVERY

Description

Compact air supply and exhaust ventilation unit VUE

100 P mini is a simple and effective energy-saving

solution ventilation of apartments, cottages, single-

family houses, workshops and trade premises.

The unit is a fully-featured ventilation unit that

provides air cleaning, fresh air supply to the premise

and removal of extract air from the premise. Extract

air thermal energy is transferred to the cross-flow

heat exchanger and is used to warm up the supply

air flow. Built-in heat exchanger prevents heat losses

and saves operating costs for heating in winter and

air conditioning in summer.

Due to the compact casing and silent operation the

VUE 100 P mini unit can be installed behind suspended

ceiling. The unit is designed for connection to Ø 125

mm round air ducts. Several rooms may be ventilated

if they are connected with air distribution network.

Supply and extract air flows are purified through two

filters with filtering class G4. The filters prevent dirt

and dust ingress into the room and protect the unit

components against contaminations.

Fans

The unit is equipped with reliable supply and exhaust

fans with forward curved blades that are powered by

Operating logic

• Warm extract air is moved by exhaust fan from the premise through the extract filter and heat exchanger, where it transfers thermal energy to its elements and then is exhausted outside.

• Cold intake air from outside is moved by the supply fan first to the supply filter where it is purified, then to the heat exchanger where it absorbs thermal energy from extract air and then supplied to the room.

• The heat exchanger reduces heat losses and saves operating costs for heating in winter and air conditioning in summer.

Operation logic of the unit with CO2 sensor:

An unoccupied ventilated premise has low CO2

concentration and requires no intensive ventilation.

The unit operates at low speed for minimum

permanent ventilation.

As people come inside, CO2 concentration in the

premise increases and the signal from CO2 sensor

closes relay contact.

The unit is turned to maximum speed until CO2

concentration in the room drops down and the

contact is opened. After that the unit reverts to the

low speed.

To arrange this operating logic it is required to

connect any sensor with relay output and to

connect it to the respective unit input. The sensor is

available upon separate order.

Mounting

The unit is designed for inner mounting in glazed

balconies, auxiliary premises, in the attics and is

allowed for use at the ambient air temperature not

below -15 °C. If the unit is intended to operate at

low outside temperatures, its drain pipe must be

heat insulated to prevent condensate freezing.

The unit must be fixed to the wall with anchor bolts

or mounted on the floor in a position that enables

condensate drainage. While mounting the unit

provide service access on the front panel side. The

panel may be fully removed if required.

Extra accessories

The SR duct silencers are recommended to install

in the supply air duct to ensure extra sound

attenuation.

Description

The air handling units VUT 300/301 EVK mini EC units

with heat recovery connected to the kitchen hood are

the ideal solution for energy-saving ventilation of the

flats and cottages. The units have two operation logics:

Heat recovery operation mode. When the kitchen

hood is turned off, air is extracted through the air

ductworks and transfers heat to supply air through

the heat exchanger.

Kitchen hood operation mode. When the kitchen

hood is turned on, air is extracted through the kitchen

hood and is exhausted directly through the exhaust

duct outside. Both operation modes provide balanced

ventilation in the room.

Compatible with round Ø125 mm air ducts.

Control and automation

The unit has integrated automation with the

control from the multifunctional built-in control

panel for the VUT 300 EVK mini EC model or the

external control panel for the VUT 301 EVK mini EC

model. Both models are controllable from a remote

controller (optional accessory). The speed control

buttons for the kitchen hood mode are located on

the front panel of the kitchen hood.

Control and protection functions:

Turning the unit on/off from the control panel.

Air supply to the electric heating elements during

the unit shutdown.

Three fans speeds are adjusted during the system

setup.

The heat exchanger downstream of the heat

exchanger warms up supply air flow up to the

comfortable temperature.

Input for alarm signal from the fire fighting

system.

The supply fan is turned off in case of freezing

danger for the period required for the heat

exchanger defrosting.

Changeover between heat recovery and kitchen

hood operation modes.

Relay input for connection of the CO2 / humidity

/ IAQ or any other sensor that switches the unit to

maximum speed.

Filter clogging control by motor hours.

Unit week schedule setting.

Controllable ventilation on demand:

The unit is equipped with a contact for relay

signal from an external sensor. The unit operation

according to an external sensor (for example, CO2

sensor) enables to reduce energy demand.

Operation logic of the unit with CO2 sensor:

An unoccupied ventilated premise has low CO2

concentration and requires no intensive ventilation.

The unit operates at low speed for minimum

permanent ventilation.

As people come inside, CO2 concentration in the

premise increases and the signal from CO2 sensor

closes relay contact.

The unit is turned to maximum speed until CO2

concentration in the room drops down and the

contact is opened. After that the unit reverts to the

minimum speed.

To arrange this operating logic it is required to

connect any sensor with relay output and to

connect it to the respective unit input. The sensor is

available upon separate order.

Mounting

The unit must be fixed to the wall with anchor bolts

in a position that enables condensate drainage.

While mounting the unit provide service access on

the front panel side.

To ensure the correct supply air warming up

function, install the duct temperature sensor in the

supply air duct (included in the delivery set) not

more than 1 m from the supply air duct end.

Extra accessories

CO2-1 or CO2-2 sensors are recommended for

arrangement of automatic control of air capacity

and extra energy saving.

Heat exchangers

The units incorporate two heat exchanger types:

The aluminium heat exchangers are designed to

ensure sensible heat energy transfer from extract to

supply air flow. The heat exchangers are distinguished

by long service life in a cold climate.

The enthalpy heat exchangers of polymerized

cellulose are designed to recuperate both sensible

and latent energy. These heat exchangers are

frost-proof and produce no condensate. The units

with polymerized cellulose heat exchangers are

recommended for use in air conditioned premises.

The unit VUT2 250 PU EC is equipped with two

aluminium cross-flow heat exchangers and two drain

pans.

The unit VUE2 250 PU EC is equipped with two

enthalpy cross-flow heat exchangers of polymerized

VENTS VUT H

Description

Air handling unit VUT H is a complete ventilation units

designed for air filtration and supply to the premises

and exhaust air removal. During the operation process

the extract air heat is transferred to the supply air

through the plate heat exchanger. All the models are

designed for connection with Ø 125, 150, 160, 200,

250, 315 mm round ducts.

Casing

The casing is made of aluminium profile, double

skinned with 20 mm mineral wool heat-and sound-

insulating layer.

Filter

Two incorporated G4 panel filters for extract air

ventilation and F7 filters for supply air ventilation are

supplied with the unit.

Fans

The unit is equipped with supply and exhaust

centrifugal double-inlet fans with forward curved

blades and built-in thermal overheating protection

with automatic restart. The electric motors and

impellers are dynamically balanced in two planes. The

ball-bearings used with motors are designed for at

least 40 000 hours operation and are maintenance-

free.

Heat exchanger

The cross-flow air-to-air heat exchanger block is

manufactured from aluminum plates. Whenever heat

recovery is not required the heat exchanger block

can be easily replaced by a “summer” block. The unit

is also equipped with the drain pan for condensate

water drainage as well as built-in freezing protection

system. Its operating principle is based on switching

the supply fan off as the temperature sensor requires.

Warm extract air heats the heat exchanger. Then

the supply fan switches on and the unit continues

operating under rated conditions.

Control

The motor speed is controlled by means of 4-step

control switch by means of selecting the minimum,

average or maximum speed or the unit shutdown.

Mounting

Air handling unit is mounted on the floor and

suspended to the ceiling by means of a seat angle

with anti-vibration mounts or attached to a wall with

brackets. The unit can be mounted either in service

spaces or in main premises above the suspended

ceiling, in the pocket or can be placed directly in the

room. Mounting in any position shall provide correct

condensate drainage. Access for the fan maintenance

and filter cleaning shall be provided from outside of

the side panels.

Description

VUT H air handling unit is a complete air handling

unit designed to provide both supply and exhaust

ventilation with air filtering and heat recovery. The

extract air energy is used to heat up the supply fresh air

through the heat exchanger. Applied in ventilation and

conditioning systems for various premises requiring

economic solution and controllable air exchange.

EC motors reduce energy consumption by 1.5-3 times

and ensure high efficiency combined with low noise

level. All the models are designed for connection to

160 and 200 mm round ducts.

Casing

The casing is made from aluminium profile, double-

skinned with 20 mm mineral wool heat- and sound-

resistant insulating layer.

Filter

Two incorporated G4 panel filters for extract air

ventilation and F7 filters for supply air ventilation are

supplied with the unit.

Motor

The double-inlet impellers with forward curved

blades are powered by high-efficient electronically

commutated (EC) external rotor motors. As of

today such motor type is the most state-of-the-

art and progressive solution for energy saving.

EC motors are featured with high efficiency and the

best control over the whole speed range. Premium

efficiency (reaching 90%) is an absolute privilege of

electronically commutated motor.

Heat exchanger

The counter-flow air-to-air heat exchanger is made

of polystyrene plates. Whenever heat recovery

is not required the heat exchanger block can be

easily replaced by a “summer” block. The unit is

also equipped with the drain pan for condensate

drainage as well as built-in icing protecting system. Its

operating principle is based on switching the supply

fan off as the temperature sensor requires. Then the

supply fan switches on and the unit operates under

the rated conditions.

Control

The unit is controlled by means of external control

signal 0-10 V (e.g., R-1/010 speed controller

for ЕС motors). Air capacity control depends on

temperature level, pressure and smoke conditions

and other system parameters. Should the value of the

control parameter get changed the EC motor changes

its rotation speed accordingly and boosts as much air

flow as required for the ventilation system.

Mounting

Air handling unit is mounted on the floor, suspended

to the ceiling by means of a seat angle with inserted

vibration-damping element or attached to a wall with

brackets. The unit can be mounted either in service

spaces or in main premises above the suspended

ceiling, in the pocket or can be placed directly in the

room. Mounting in any position shall provide correct

condensation water drainage. Access for maintenance

shall be provide through the side panels on the left

from supply air side.

Air handling units with the air capacity up to 600 m3/h and heat recovery efficiency up to 95% in compact sound-and

heat-insulated casing

Heat exchanger

The heat exchangers have high efficiency and are

manufactured from aluminium plates. The unit is also

equipped with the drain pan for condensate drainage.

Heater

The electric heater (for the unit VUT EH) or the water

heater (for the unit VUT WH) at outlet from the heat

exchanger is designed for warming up of supply

air up to the set level if heat recovery is not enough

to attain the set supply air temperature. The water

heaters are designed for max. operating pressure

1.0 MPa (10 bar) and max. heat medium operating

temperature 95 °C.

Automation and control system

The unit incorporates an integrated automation and

control system with a multi-functional control panel

with LCD display. The standard delivery set includes

10 m connection cable for connection to the remote

control panel. The unit has the freezing protection

function to prevent the heat exchanger freezing

by means of actuating the bypass damper and

controlling water heater. As the temperature sensor

warns of the freezing danger, the bypass air damper

is opened and the intake air is directed through the

air duct beside the heat exchanger. As the heat

exchanger is warmed the supply air temperature rises

up to the set level while passing through the heater.

Meanwhile the warm extract air warms up the heat

exchanger. After the freezing danger is no longer

imminent, the bypass damper shuts the bypass duct

and the unit reverts to the standard operation mode.

Description

VUT EH EC air handling units with the electric heating

battery and VUT WH EC with water heating coils are

the complete ventilation units designed to provide

both supply and exhaust ventilation, air filtration

and cleaning as well as removal of contaminated

exhaust air. The exhaust air energy is transferred to

supply air through the plate heat exchanger. Applied

in ventilation and conditioning systems for various

premises requiring economic solution and controllable

air exchange. EC motors reduce energy consumption

by 1.5-3 times and ensure high efficiency and low

noise level at the same time. All the models are

compatible with Ø 150, 160 and 200 mm round ducts.

Modifications

VUT EH EC – a range of compact Energy saving Air

Handling Units (AHU) equipped with intake and

exhaust centrifugal fans with EC motors, counter-

flow heat recovery elements, electric heater and air

filters.

VUT WH EC – a range of compact Energy saving

Air Handling Units (AHU) equipped with supply and

exhaust centrifugal fans with EC motors, counter-

flow heat recovery elements, water or glycol heating

coils and air filters.

Casing

The casing is manufactured from aluminum-zinc

compound with internal 25 mm mineral wool heat-

and sound- insulating layer.

Filter

Two incorporated G4 panel filters for extract air

ventilation and F7 filters for supply air ventilation are

supplied with the unit.

Fans

The double inlet impellers with forward curved

blades are powered by high efficient electronically

commutated (EC) direct current motors with external

rotor. As of today, such motor type is the most

advanced solution for energy saving. EC motors are

featured with high efficiency and the best control

over the whole fan speed range. Premium efficiency

(reaching 90%) is an absolute advantage of the

electronically commutated motors.

Heat recovery

The units are equipped with the high efficient heat

exchangers reaching up to 95%. VUT EH EC and

VUT WH EC models are fitted with the counter-

flow heat exchangers made of polystyrene. The

unit is equipped with the drain pan at the bottom

of the heat exchanger for condensate drainage.

Heater

The electric heater (for the unit VUT EH) or the water

heater (for the unit VUT WH) at outlet from the heat

exchanger is designed for warming up of supply air up

to the set level if heat recovery is not enough to attain

the set supply air temperature. The water heaters are

designed for max. operating pressure 1.0 MPa (10 bar)

and max. heat medium operating temperature 95 °C.

Control and automation

The unit incorporates an integrated automation

and control system with a multi-functional control

panel with LCD display. The standard delivery set

includes 10 m connection cable for connection to

the remote control panel. The unit has the freezing

protection function to prevent the heat exchanger

freezing by means of actuating the bypass damper

and controlling water heater. As the temperature

sensor warns of the freezing danger, the bypass

air damper is opened and the intake air is directed

through the air duct beside the heat exchanger.

As the heat exchanger is warmed the supply air

temperature rises up to the set level while passing

through the heater. Meanwhile the warm extract

air warms up the heat exchanger. After the freezing

danger is no longer imminent, the bypass damper

shuts the bypass duct and the unit reverts to the

standard operation mode.

VUT EH EC control and protection functions

control from the control panel: switching on/off,

speed selection, timer, faults;

maintaining the set room temperature by the

sensor on the control panel – smooth heating

capacity control;

three-speed fan speed control (low-medium-

high);

unit operation according to daily and week

schedule (timer adjustable from the control panel);

safe start-up/shutdown of the fans;

electric heater overheating protection by the

temperature sensor installed in the supply air

duct and by two overheating thermostats, one

thermostat activated at 50 °C with automatic reset

and another thermostat activated at 90 °C with

manual reset. Blowing of the heating elements for

heat removing at the end of the heating cycle;

filter clogging control by engine hours.

VUT WH EC control and protection functions

control from the control panel: switching the

unit on/off, room temperature display, fan speed

selection (low/medium/high speed);

each fan speed is 100% adjustable both for supply

and exhaust fan during the system setup;

maintaining supply air temperature set from the

control panel by controlling the circulation pump

and actuating the heat medium regulating valve;

freezing protection of the water heating coils by

the exhaust temperature sensor and the return heat

medium temperature sensor;

safe start-up/ shutdown of the fans, warming up

of the water heater before start-up; maintaining

the set return heat medium temperature when the

fan is off;

actuating the external air dampers with a return

spring;

unit shut down at signal from the fire alarm

system;

smooth bypass damper control in the bypassing

mode to prevent the heat exchanger freezing.

Mounting

The unit is designed for indoor mounting. While

mounting the unit provide the correct condensate

collection and drainage. Access for the unit

servicing and filter cleaning is from the side panels.

Accessories

For attenuation of sound generated by the fan it

is recommended to install the duct silencer (refer

SR) from inside before the unit. For vibration

absorbing it is recommended to install the flexible

anti-vibration connectors (refer VVG) on both sides

of the unit.

The VUT WH units are recommended to be

equipped with automatic air dampers for the water

heater freezing protection when the fans are off.

The mixing units USWK are recommended for

smooth supply air temperature regulation in the

units equipped with water heaters. The mixing unit

USWK with three-way heat medium regulating

valve and circulation pump provides smooth heating

capacity regulation and minimizes the water heater

freezing danger.

VUT EH EC ventilation and air exchange example in the cottage

Page 105: AHU Residential 2013

104

Description

The air handling units VUT EH EC ECO are the fully-

featured ventilation units that ensure air filtration,

fresh air supply and stale air extract.

The sensible heat contained in the extract air is

recuperated in the high-efficient plate counter-flow

heat exchanger to warm up supply air.

The units are applied as components of ventilation

and air conditioning networks for various premises.

The high-efficient EC motors and expanded counter-

flow heat exchanger surface make the ECO series

energy saving parameters one of the best at the

market.

Compatible with round Ø 160, 200 and 250 mm air

ducts.

Casing

Made of aluzinc, internally filled with 25 mm mineral

wool heat- and sound-insulating layer.

Filter

Supply air flow is purified through a bag filter with

filtering class G4. Extract air flow is purified through

a panel filter with filtering class G4.

Fans

High-efficient electronically-commutated motors

with external motor. The unit sizes 300 and 400

are equipped with constant flow fans with forward

curved blades and the unit size 600 is equipped with

fans with backward curved blades.

Such motors are the most state-of-the-art energy-

saving solution.

EC motors are featured with high performance

and total speed controllable range. High efficiency

reaching 90 % is the premium advantage of the

electronically-commutated motors.

Heat exchanger

High-efficient plate counter-flow polystyrene heat

exchanger. The drain pan under the heat exchanger

block ensures condensate removal.

Heater

The unit may be equipped with an electric heater (not

included into the delivery set) to warm up supply air up

to the comfortable temperature if the set temperature

cannot be attained with heat recovery only.

Control and automation

The unit includes integrated automation and a

multifunctional control panel with a sensor graphical

display.

The delivery set includes a signalling cable, 10 m long,

for connection with the control panel. The integrated

freezing protection system is designed to prevent the

heat exchanger freezing at low temperatures.

In case of freezing danger indication by the

temperature sensor the supply fan is turned off to

let warm extract air flow pass by the heat exchangers

and warm them up. After freezing danger is no

longer actual, the supply fan is turned on and the unit

reverts to the standard operation mode.

If the unit is equipped with a heater, the temperature

sensor activates opening of the bypass damper to let

supply air flow go by the heat exchanger along the

bypass air duct. During the heat exchanger defrosting

the supply air is heated up to the required temperature

in the air duct. Meanwhile the warm extract air warms

up the heat exchanger. After the heat exchanger

defrosting the damper closes the bypass duct and the

unit reverts to the standard operation mode.

Control and protection functions

from the control panel:

turning on/off, speed selection, timer, daily and

weekly schedule, errors;

maintaining set room or duct air temperature;

control by the duct humidity sensor (optional) or

the humidity sensor integrated into the control panel.

switching of three fan speeds;

daily and weekly operating schedule;

optional electric heater control and protection;

filter clogging control by motor hours.

Mounting

The unit is designed for the suspended or floor

mounting. Access for the unit servicing and filter

cleaning on the front panel side.

The standard delivery set includes 10 m connection

cable for connection to the remote control panel.

The unit has the freezing protection function to

prevent the heat exchanger freezing by means of

actuating the bypass damper and controlling water

heater. As the temperature sensor warns of the

freezing danger, the bypass air damper is opened

and the intake air is directed through the air duct

beside the heat exchanger. As the heat exchanger

is warmed the supply air temperature rises up to

the set level while passing through the heater.

Meanwhile the warm extract air warms up the heat

exchanger. After the freezing danger is no longer

imminent, the bypass damper shuts the bypass

duct and the unit reverts to the standard operation

mode.

VUT PE EC control and protection functions

control from the control panel: switching the

unit on/off, room temperature display, fan speed

selection (low/medium/high speed);

each fan speed is 100% adjustable both for supply

and exhaust fan during the system setup;

maintaining the set room temperature by the

sensor on the control panel – smooth heating

capacity control;

safe start-up/shutdown of the fans;

electric heater overheating protection by the

temperature sensor installed in the supply air

duct and by two overheating thermostats, one

thermostat activated at 50 °C with automatic reset

and another thermostat activated at 90 °C with

manual reset. Blowing of the heating elements for

heat removing at the end of the heating cycle.

General description of VUT PW EC control

system;

smooth bypass damper control in the bypassing

mode to prevent the heat exchanger freezing.

Mounting

The unit is designed for indoor mounting. While

mounting the unit ensure its correct position to

enable condensate collection and drainage. Access

for servicing and cleaning of the filter is from the

right or left side panel for the dimension types

350, 600 and 1000 and from the bottom for the

dimension types 2000 and 3000.

Accessories

For attenuation of sound generated by the fan it

is recommended to install the duct silencer (refer

SR) from inside before the unit. For vibration

absorbing it is recommended to install the flexible

anti-vibration connectors (refer VVG) on both sides

of the unit.

To disable uncontrollable air flow when the fans

are off and to prevent the water heater freezing

the units are recommended to be equipped with

automatic air dampers.

The mixing units USWK are recommended for

smooth supply air temperature regulation in the

units equipped with water heaters. The mixing unit

USWK with three-way heat medium regulating

valve and circulation pump provides smooth heating

capacity regulation and minimizes the water heater

freezing danger.

AIR HANDLING UNITS WITH HEAT RECOVERY

Description

The air handling units VUT R EH with an integrated

electric heater or VUT R WH with an integrated

water heater are the ready-to-use ventilation units

that provide air filtering, supply of fresh air to the

premises and exhaust of stale extract air from the

premises with synchronous thermal energy transfer

from extract air flow to the supply air flow through

the rotary heat exchanger. The VUT R models are used

in ventilation and air conditioning systems installed

in various premises that require reasonable energy

saving solutions and controlled ventilation systems.

EC motors reduce energy demand by 1.5-3 times and

ensure high performance and low noise operation. All

the models are designed for connection to Ø 160 and

250 mm round air ducts.

Modifications

VUT R EH - models with electric heater, fans with EC

motors, rotary heat exchanger.

VUT R WH - models with water (glycol) heater, fans

with EC motors, rotary heat exchanger.

Casing

The casing consists of a frame and three-layer 20

mm thick panels made of AlZn plate internally filled

with mineral cotton for reliable sound- and thermal

insulation.

Due to the specially designed removable side panels

the unit requires little space for servicing and

accessing to all the unit components.

Filter

G4/F7 supply and exhaust filters prevent dirt ingress

into the the room and are the essential components

that protect that unit elements against soiling.

Motor

The units are equipped with high-efficient direct

current electronically-commutated (EC) motors

with external rotor and backward curved impeller

blades. Such motor design is the most progressive

solution in energy saving. EC motors are featured

with high performance and well controllable speed

range. Premium efficiency reaching 90% is a definite

advantage of electronically commutated motors.

Rotary heat exchanger

The rotary heat exchanger is a rotating short cylinder

internally filled with corrugated aluminium band

placed in such a way as to ensure passing of the supply

and exhaust air streams through the heat exchanger

but to exclude their direct contact. While rotating of

the heat exchanger the band inside of it first comes in

contact with supply air stream and then with exhaust

air stream. Consequently the aluminium band is heated

up and cooled down by turns and recuperates the

thermal energy and moisture contained in the warm

extract air to cold intake air flow from outside. The

advantages of the rotary heat exchanger as compared

to the plate air-to-air heat exchangers include higher

efficiency, maintaining comfortable indoor humidity

level and extremely low freezing danger (it is nearly

zero for rated temperature and humidity conditions).

Heater

Electric heaters (VUT R EH EC models) or water

heaters (VUT R WH models) are used for application

of the air handling unit at low outdoor temperatures.

If heat recovery is not sufficient to reach the set

supply air temperature, the air heater is turned

automatically on and warms up the supply air flow.

The heaters are equipped with protecting devices

to ensure safe and reliable operation of the unit.

The water heaters are designed for max. operating

pressure 1.0 MPa (10 bar) and max. heat medium

operating temperature 95 °C.

Control and automation

The unit is equipped with a built-in automation

system and a multi-functional control panel with a

graphic indicator. The standard delivery set includes

a 10 m cable for connection to the control panel.

VUT R EH EC automation functions:

turning the unit on and off according to set

parameters;

week-scheduled operation;

setting of the required supply air temperature

and air flow with an external control panel;

operation according to timer settings;

regulation of air control dampers;

Prolong the line up to the point where it crosses the outside air temperature indicated as red curve (e.g., +5 °С) and draw a horizontal line from this point to the right to the intersection of water in/out temperature curve (e.g., 70/50 °С). From this point draw a vertical line up to the scale of heating coil capacity (5.8 kW).

Water flow. Prolong the line down to water flow axis at the bottom of the graphic (0.04 l/s).Water pressure drop. Draw the line from the point where line crosses the black curve to the pressure drop axis. (0.5 kPa).
