2.7 Working Principle

Air-conditioning using the compressor refrigeration

Main parts of the refrigeration: compressor, condenser, expansion valve, an evaporator,

internal fan, external fan, heater

Principle of refrigeration: Compressor suck refrigerant gas from evaporator, and compressed,the compressed refrigerant gas pushed into condenser to cooled into refrigerant liquid, then pass theexpansive valve, the refrigerant into evaporator and evaporate to cool air.

2.8 Air duct design

Internal circulation and external circulation of the air duct is shown in Figure2-3.

Mount the out cover to the shelter---only side and half embeded needed. ( the purpose of theout cover is provent rain penetrate into the product also protection the product access fromexternal side).

!! Note: the out cover is not a standard part of product, normally it is provided by

an engineering company who install the product.

8)

The mechenical part of installation is finished till now. please double check.

Double check lists

1)

Dont apply this unit in high oli, burning gas, explosive gas, strong corrosivity condition, the

ambient air must be under 60, and the humidity not higher than 95%.

2)

Make sure that the lean of the product nor more than 3.

3)

Make sure that the cabinet should be sealled well to avoid the cooling losing and avoidambient moisture penetrate into cabinet, this will avoid produce more condensate water.

4)

Dont power on the unit immediately after finish the installation until the uint keep up standfor more than 30 min.
