Condenser (Air Cooled Heat EXCHANGER)
The condenser is placed in front of the engine's radiator. In the cooling system it is placed on the high pressure side opposite the compressor and receiver drier.
The task of the condenser is to cool, so converting the hot, gaseous refrigerant to a liquid.
The compressor pumps refrigerant gas under high pressure, which has a temperature of between 70 and 110 °C, into the intake on the top of the condenser. When the hot gas flows through the tubular coil it is cooled and changes into liquid (condenses). The heat removed from the gas during this process is emitted to the surrounding air.
The engine cooling fan increases the air flow through the condenser. This increases the transfer of heat from the refrigerant to the ambient air.
The amount of heat emitted = the amount of heat taken up by the evaporator + the amount of heat supplied by the compressor. In order to receive sufficient cooling capacity, the refrigerant's condensation temperature must lie above the ambient air's temperature.
The fan is controlled by the A/C switch and the fan thermostat, which is located on the engine's refrigerant circuit.
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. The receiver drier is integrated with the condenser on the left-hand side of the condenser.
