2.6 MotorMotor is a belt-drive type's product and applies more than insulationclass, " F " Class.

Motor’s airtight and watertight protection grade is IP54, and although awater drop Invades from any direction, it can be a structure to be pro-tected.

Make easily adjust V-belt tension by manufacturing motor base as aslide style.

2.7 Drive UnitFan & motor pulley is able to maximize power delivery efficiency by applying multi ribbed pulley.

For rubber belt (V-BELT)’s quality, by applying multi ribbed pulley and thus excelling in belt’s pliability and flexi-bility, it is stable power delivery at high-speed rotation and small size and, electric motion efficiency is able toincrease up to 98% by minimizing belt slip.

2.8 IsolatorBy attaching Isolator to fan motor frame, make it capable of absorbingfan’s vibration.

By attaching canvas between fan’s exit and AHU casing, design andmake to prevent fan’s vibration and noise delivery.

When setting up motor outside of AHU, it is essential to set up horizon-tally being pushed preventer to prevent being pushed while driving fanbetween fan part and the part connected to it.

Prevent delivery of vibration and twisting originated from moving by set-ting up horizontally being pushed preventer between return fan sectionand other section.

2.9 CoilDesign and make as counter flow style which is the most effi-cient fluid flowing form for heat exchange of coil and air.

When coil’s length is more than 1m, use middle reinforcingsteel sheet to prevent frame’s bending or transformation

Make it without winding and unevenness to minimize refriger-ant’s flow resistance.

Header and U-bend’s welding part have enough intensity tobear maximum use pressure.

By executing coil’s pressure test as 20kg/cm2 at Water coil(41kg/cm2 at DX coil), and maximum water tempera-ture as 150°C, there must not be a leak, transformation, explosion, and so on at coil’s each part.

Make coil’s safety rate more than 15-20%, and make it more than two rows

2.13 HumidifierSteam injection Type

This type of humidifier is fed by steam from a main supplyrather than being generated locally by a self-generative unit.

An effective system which ensures;

- Low operating cost

- Hygienic humidification

- High steam output per metre of lance.

- Very low noise levels.

- Simplified duct and piping requirements.

- Close spacing where multiple lances are needed.

- Low steam ejection velocity for efficient air / steam mixing.

Evaporative Type

Evaporative humidifiers provide very economic humidificationas, unlike steam humidifiers, the water does not need to beheated.

Running costs can be 150 times less than steam systemsrequiring only a single phase power supply. Many operating fea-tures make these humidifiers extremely hygenic and safe touse.

2.14 Heat Recovery systemIn order to conserve the energy consumption by exchanging energy between the supply and exhaust airstreams, various types of heat recovery systems can be provided as an integral part of LG AHU unit. Thesedepend upon special installation and other Requirements

Plate Heat Exchanger

Plate heat exchangers are used in order to separate supply airand exhaust air completely. Air flows of different temperaturesare passed by each other by the crossflow principle. The airflows are 100% seperated by a divididing wall out of thin aluminium sheets. This excludes the possibility of impurity,odour and humidity.

Technology & Performance

Low space requirement

Statically ideal distance between plates

Due to double folding high tightness and strength up to 250(mmAq) pressure difference

Rotary Heat Recovery System

The energy recovered is used to precondition (precool/pre-heat) the supply air. Thereby reducing the energy needed tocondition fresh air.

The energy recovery is achieved when the enthalpy/energyrecovery rotor slowly rotates between the counter flowingexhaust and supply air streams absorbing the sensible as wellas the latent energy. Installing this system helps to reducecapital/operating cost of air conditioning equipment in new aswell as existing buildings.

8.2 Foundation

* D : Need to enough space for duct work

* L : On the designated access side of the unit, workingareas must be equal to the width of the unit.

* H : Allowance for coil connections, must be "L" + 200 mm.

When selecting and preparing the unit site, followthese guidelines:

1. Ensure that the site can support the total weight ofthe unit. Unit weight figures only provide total grossweights and do not include the additional weight forwater in any coils.

2. Confirm that the foundation of the mounting platformis large enough to include the unit dimensions plusservice plus service access.

3. The floor or foundation must be level for correct coildrainage and condensate flow.

4. Provide adequate lighting for maintenance person-nel to perform maintenance duties.

5. When the unit is positioned on site, there must besufficient space around the unit to ensure that cor-rect operation and effective maintenance can becarried out.
