Condenser (air cooled heat exchanger)
The condenser is located in front of the engine radiator. The airflow and engine cooling fan (FC) blow air through the condenser. In the cooling system, the condenser is located on the high pressure side opposite the compressor and the receiver drier.
The condenser consists of pipe loops in which the refrigerant flows. The loops have flanges to increase the heat radiating surface.
When the refrigerant enters the condenser it is in gas form and has both high pressure and high temperature. In the condenser the hot refrigerant loses some of its heat to the surrounding cooler air. The refrigerant then condenses and changes into liquid form. The amount of heat given off = the amount of heat taken up in the evaporator + the amount of heat supplied by the compressor. In order to supply sufficient cooling capacity, the condensation temperature of the refrigerant must be greater than the temperature of the outside air.
