Industrial Cabinet Air Conditioner R134a AC220V Door Mounted
1. Industrial Cabinet Air Conditioner Introduction
Industrial cabinet air conditioner is one kind of refrigeration product self-developed for cabinet. It is applicable in the place where the cabinet internal heat is very large, the internal electronic equipment is sensitive to the environment temperature and which should be isolated internally and externally completely. This product has multiple functions, high reliability, and has the feature that it can start to work without complex debugging after powering.

6. Cooling system
6.1 Basic Components
Cabinet air conditioner is composed of compressor, condenser, evaporator, electric control system, expansion valve and capillary tube, dry filter and fans etc.
6.2 Cooling Theory
The compressor takes in the gas refrigerant from the evaporator and compresses it into high temperature and high pressure then sends it into the condenser. The refrigerant will release heating in the condenser and then the cold high pressure liquid goes through capillary throttling and turns into low temperature and low pressure and then flows in to the evaporator. The refrigerant will absorb heat and then turns into gas in the evaporator. Thus forms the cooling cycle system.
The condenser and evaporator has circulation fan to enhance air convection and heat exchange efficiency. The heat exchange between condenser and air is outside the control box and that of evaporator and air is inside the control box.
The electrical system is mainly monitoring the temperature of the cooled closed cabinet and controls the cooling circulation by setting temperature.
