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.
