Basic Elements of Automotive Air Conditioning Systems

We sure all take for granted our car and trucks cooling and air conditioning systems until they can’t operate in the hot summer and we are sweating as we drive, fall prey to high humidity or both. Basically automotive air conditioning systems are the same and reliable, needing a minimum of maintenance. Though, when these cooling systems encounter problems it is best option to have a basic know-how of automobile refrigeration and cooling systems so that we can act fast and succinctly know the problems and issues and give it to our local garage auto mechanic man or your dealership professional service technician.

The typical work of air conditioning as well as wintertime heating systems and glass defrosters is to maintain the temperature of the passenger. The air conditioner radiates heat from the passenger compartment to the outside air while continuously reducing humidity and moisture as well. In cooler season of the driving year the heating system does the reverse providing the heat from the engine to the passenger compartment.

The basic piece of you vehicle cabin cooling systems is the compressor - which is naturally a basic pump, and the magnetic clutch that functions to disengage the compressor to control the circulation of refrigerant through the system.Subsequently is the condenser coil itself that disperse the heat picked through the refrigerant from the evaporator coil that is in the passenger compartment itself.

The receiver dryer keeps refrigerant making it dirt-free and eliminating moisture.

Second in line is the expansion valve that functions to limit the high pressure liquid from the receiver into the evaporator core, resulting the high pressure liquid to evolve into a lower pressure low temperature gas.

Last but not the least, are the evaporator core that is like a radiator container connected between the expansion valve and what is called as the “suction throttling valve”. The suction throttling valve contains a pressure in a range of 28 and 2p psi, pounds per square inch measurement. And for discussions of fast diagnosis of low refrigerant fluid many auto air conditioners always have a transparent “sight gas”.

Knowing the basic components and terminology of auto cooling refrigerant air conditioning systems can facilitate in describing breakdown and maintenance troubles with your local garage mechanic or auto dealership service department. All in all with the type and number of all of these complicated components it is amazing that our automobiles’ air conditioning systems are so dependable and worry-free.
