The basic purpose of air curtains is to prevent air from undesiredexchange (draught) through an open door connecting two roomswith different climatic parameters. In most cases, they are installed

at the main entrance of a building but sometimes they need to beapplied indoors between two rooms with different purposes, i.e. temperatures. Such an invisible barrier is realized by directing theair flow of an appropriate velocity into the visible plate below theopening. The barrier protects interiors from ingression of outdoor cold or wam air, dust, insects, unpleasant smell and other pollut-ants (Fig. 1.1). Moreover, additional heating of the air flow (electricor hot water heaters) is able to satisfy most thermal needs of therooms protected by air curtains whereas an installed filter ensurescontinuous indoor air purification. Air curtains are mostly installedabove the entrance by means of visible or suspended ceiling instal-lation and are characterized by simple mounting and maintenanceduring exploitation. The application of air curtains is multiple and their usefulness is evident in the following effects:

• Controlling energy expenses as result of heating/ cooling• Preventing air from dust, insect and smoke ingression through an open door • Stabilizing microclimatic conditions by blocking cold or warm air penetration

Another important effect of air curtains is cancelling temperaturedelayering, e.g. during the heating season warm air raises to higherzones of a room due to lift whereas cold air stays in lower zonesof the room.

It brings to subjective feeling of cold, especially on legs while theair above the movement zone remains hot. On such occasion notmuch will be achieved if the effect of heating is increased.Since air curtains are installed at heights above the movement zone, they intake warm air and direct it at high velocities to lower zonesmaking a macro-whirlpool in the entire room (Fig. 1.2). Equalizing the temperatures of higher and lower zones neutralizes the feeling

of cold and, simultaneously, need for additional heating. Finallyair curtains are economical due to their low energy consumption.

Klimaoprema Quant Line air curtains are designed for simple instal-lation, handling and maintenance while high quality components therefor guarantee functionality, reliability and longevity. The main

characteristics of air curtains Quant Line are the following:

• All models available lengths between 1 and 1,7 m. • Opening heights range from 2 to 5 metara. • Models without heater (N), with an electric (E) or with

a hot water (W) heater are all available (models with an electric heater are supplied without an air filter). • Control panels are equipped with a three speed fan controller and a double electric heating mode. • Available air flow regulation through special outflow blades. • Possible harmonization with a door opening level. • Various suspension elements as well as other installation and connecting elements make mounting

simple and quick.

The basic components and corresponding charactheristics:Air curtain casings are made of sheet steel, powder coated in basicRAL 9010 colour (white). Simple mounting provides a quick andeasy approach and demounting of all the components.

Description and Marking

Air curtain casings are labeled with the protection class IP 20. Fansare constructed radially and contain an installed electric motoractuator. The wings are angled and do not produce much noise.

Ventilators are labelled with the protection class IP 42 and are sup-plied with single-phase actuators containing self-greasing bearingswhich enable quiet and long-term work without maintenance.Electric heaters are made of highly alloyed steel with brass bladesin order to increase the total area. They are distributed evenly through an outlet area, which enables high quality transmission ofheat and the maximum shelflife. The power of electric heaters isselected according to the flow keeping the supply air temperatureoptimal. The protective border thermostat switches air curtains offif the casing temperature exceeds 95°C. Hot water heaters consistof copper pipes with aluminium blades. The mechanical expansionof the copper pipes ensures maximum heat transmission from theheating medium to the supply air. Heaters are in fact heat exchang-ers designed for water as a heating medium up to 100°C. Heaters

have been tested at 25 bar. Filters (EU2) are made of solid poly-urethane foam and can be easily demounted for control examina- tion by frontal mask opening and wired holder removal. Regardingcleaning, filters are simply blown through by means of compressedair or washed with solution with mild detergent concetration. In theend, they are washed out with water jet and then dried.

Control

GRAND and SONATA air curtains are controlled by a control panelplaced on a wall. The panel below outlines all available functions.

Depending on a series (GRAND/SONATA) or a device type (hotwater/electric heater) some buttons may be left out.

After assembling the control panel according to the given schemeand connecting it to the corresponding voltage, red LED next to the main switch ON/OFF flashes. The switch ON/OFF switches thedevice ON/OFF. Mode selection is initiated by pressing the button

PROGRAMME. In general, there are two modes available - manualand automatic.

• The manual mode provides triple speed run fun bypressing the button PROGRAMME. Air curtains with electric

heaters are equipped with two heater power levels initiated by thebutton HEATER. When the device runs at the lowest speed, thesecond heater level is automatically reduced to the first level.

• Automatic mode reflects in connection to the door openingswitch. It means that the device reacts to opening the door abovewhich it is installed. There are two installation modes:

Button for switching on/off halogen bulbs (SONATA series)

Signal LED - halogen bulbs switched on

Button for switching on/off electric heaters

Signal LED - heaters switched off

Signal LED - first level of heater power

Signal LED - second level of heater power

Signal LED - see “Automatic mode” under (b)

Signal LED - see “Automatic mode” under (a)

Signal LED - highest fan speed

Signal LED - average fan speed

Signal LED - lowest fan speed

Button for mode selection

Signal LED - device switched off

19/25



a. In the automatic mode denoted by the symbol ( ) the devicekeeps being switched off until the door opens. Then, it is actuatedat a maximum fan speed and remains active for 30 sec after thedoor closes. If the door during those 30 sec opens again, the de-vice keeps running at the maximum speed until the next door clos-

ing after which it waits for another 30 sec to be switched off. Sucha mode enables energy-saving since the device remains switchedoff while the door is being closed.

b. In the automatic mode denoted by the symbol ( ) the device runsat the first fan speed. When the door opens, the third (maximum)fan speed is actuated and, like in case under (a.), the maximumfan speed remains switched on for 20 sec after the door closes.If the device is supplied with electric heaters, this mode sets thedevice into the continuous first heater level run. the mode providescontinuous heating of the room which air cur tains are installed into.

When switching off the device (switch ON/OFF) supplied withelectric heaters, the ventilator (fan) keeps running for another 60sec in order to cool electric heaters - if the heaters have beenpreviously turned on. Also, the mode prior to switching off is memorized,

so that it is actuated again when the device is switchedon for the next time. The buton LIGHT is intended for switching on/off halogen bulbs (2x20W) regarding SONATA seriesand it does not depend on a main switch position ON/OFF.In case of multiple air curtain installation one control panel canbe connected up to 16 devices according to the enclosedelectrical shemes.

Control panel dimensions:

Through the installed adjustable blades on the supply air opening, it is possible to direct the air flow.


20/25



The regulation of hot water air curtains is carried out withregard to the supply air temperature and room temperature.The supply air temperature is set in the device itself in the

range from 30° to 50°C. The desired room temperature isset on a room thermostat which is connected to the controlpanel. When doing so, the position of the room thermostatdoes not have to be compatible with the position of the controlpanel but it should be placed in accordance with the manual

for the relevant room temperature measuring. Based on the temperature settings stated here in above, the automaticcontrol of hot water air curtains regulates the electrothermic

actuator. The actuator contains ON/OFF control but due toa long period during which the valve remains shut (about 2minute) the valve regulation is almost continuous.

The scheme below shows two modes of hot water regulation:

(a) air curtains in the heating system, (b) air curtains in the heating and cooling system.

Thermal regulation

The difference from the first case reflects in the presence of anadjoining changeover thermostat. The air curtains with water heatexchanger are not designed for air cooling, so it is inevitable tostop water flow through the device in the cooling period. Measur-ing the supply pipe temperature a changeover thermostat detects

the winter (heating) and summer (cooling) period. If the water temperature decreases below 19°C, the thermostat switches off the electrothermic actuator which, then, shuts the valve. If thewater temperature incereases above 30°C the thermostat is actu-ated again. A changeover thermostat has to be placed on a pipewith regular water flow, which, in mosta cases, means the use ofa switch valve. If it is not in case, once the valve is switched off, itcould not be switched on again. However, in such cases the useof a straight way valve (control valve) is possible if next to it there

is the main pipeline with continuous water flow which a change-over thermostat would be placed onto. The actuator site does notnecessarily have to be next to the device but it can be hidden in asuspend ceiling or displaced in another room where it will not es- thetically disturb the installation site. The regulation of air curtains

with electric heaters is carried out only in regard with the room temperature, which requires the installation of a room thermostatand its connection to the control panel according to the corre-sponding electrical schemes. All additional elements necessaryfor the thermal regulation of air curtains are shown in the sectionADDITIONAL EQUIPMENT.

Working conditions package, transport and storage

Air curtains are designed for installation and work in dry interiorswith a temperature from -10 to +40˚C and air pollutant amount(dust, chemical vapour)within the valid standards for occupied

zones.

Air curtains are initally wrapped in PE foil and then put into card-board package supported by Styrofoam/cardboard inserts. Thepackage is used exclusively for protection during transportation to installation sites and may be removed only immediately beforeinstallation.

If a device in package falls down, it can be damaged. Therefore,device transportation shall be protected from

downfalls and rolling. Air curtains may only be lifted by especiallydesigned (forklift, crane) devices with a focus on their capacity.The data on the weight of particular air cuirtains model are

stated in this manual.In case of transportation damage one should report it to aresponsible shipping company. If there is a suspicion of damage, the device must not be used. Air curtains may be stored only inrooms protected from external influences with a maximum paletteheight of 1.5 m.
