Condenser – It is the device looks like a small radiator and is used after the compressor as it provides condensing i.e. In-car air conditioning is one of the great miracles of convinces when the system is. The pressurized liquid refrigerant circulates through the series of tubes located in the condenser. It contains desiccant to absorb moisture like the accumulator does, but the receiver-drier is located on the high-pressure side instead of the low-pressure side. When the system is low on freon, it doesn’t circulate the oil as well, which will cause the compressor to be deprived of lubrication which lowers the lifespan of the unit significantly. Many consider the compressor as the heart of the air conditioning system of the car. As the name suggests, it “compresses” the refrigerant so that it turns from a gaseous state into a liquid state. All air conditioning systems have these basic parts, although different systems use various forms of sensors to monitor pressure and temperatures. Because the condenser contains a higher-temperature liquid, there is a temperature gradient between the liquid and the fresh air. The Best Cabin Air Filters (Review) in 2020. Because the refrigerant is cooler, heat moves from the air and into the refrigerant. A car air conditioning system consists of a compact version of the components of the normal air conditioner that has an evaporator, compressor, condenser, expansion device, and a fan which are fitted in a car to provide air condition inside the passenger’s compartment. The air coming from the passenger compartment gets drawn into the evaporator and blasted through the evaporator core.
