Condenser HVAC: Description and Operation

Location
The condenser is located forward in front of the radiator.

Function
Liquefies the gaseous refrigerant by cooling.

Construction And Operation
The condenser consists of a coiled line connected firmly by a series of fins. Hot refrigerant gas under high pressure is pumped at 80-125°C from the compressor into the upper inlet line of the condenser. When the hot gas passes through the coiled lines it cools until it condenses. The heat extracted from the gas during this process is transferred into the surrounding air.

Fan
The fan(s) provide a quicker means of removing the heat from the condenser and as a result a more rapid cooling of the refrigerant. The fan is controlled by means of the high pressure switch in the refrigerant line and the temperature sensitive radiator fan switch in the coolant circuit.
