Condenser (Air Cooled Heat EXCHANGER)
The task of the condenser is to cool, so converting the hot, gaseous refrigerant to a liquid.
The compressor pumps in hot refrigerant gas under high pressure. The gas has a temperature of between 70 and 110 °C in the intake on top of the condenser.
When the hot gas flows through the pipe loop, it is cooled down and condensed. The heat that is removed from the gas during this process is transferred to the surrounding air. The engine cooling fan (FC) increases the airflow through the condenser. This increases the transfer of heat from the refrigerant to the outside air.
The fan is controlled with the aid of a high pressure switch or a linear high pressure sensor located in the refrigerant line. The fan is also controlled by the fan thermostat located in the coolant circuit.
