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, it is located on the high pressure side opposite the compressor and the throttle valve.
The condenser consists of pipe loops in which the refrigerant flows. The loops have flanges to increase the heat radiating surface.
The pipe connection is made of aluminum. To reduce the rotation when connecting pipe/hoses to the junction block, there is a reinforcement (made of plastic or aluminum) on the block. When disconnecting pipes/hoses, a counterhold must be used. There is a socket for this in the junction block.
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 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.
