The vapor-compression refrigeration system has been the most widely used method for air-conditioning of large public buildings, private residences, hotels, hospitals, theaters, restaurants and automobiles. It uses a circulating liquid refrigerant as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere. Compressor The compressor is a mechanical device that increases the pressure of refrigerant by reducing its volume. Condenser The condenser is a heat exchanger which condenses refrigerant from its gaseous to its liquid state. Expansion Valve The expansion valve controls the rate at which liquid refrigerant can flow into an evaporator. Evaporator The evaporator absorbs the heat from CPU and vaporizes the refrigerant from its liquid to its gaseous state. Intelligent IC controller The operating speed of compressor is controlled by intelligent IC controller; the speed depends on CPU loading for saving energy and preventing condensation. It is so called DC Inverter Type function.
