For A Comfortable Ride in Your Car

By Star Cruiser

Standard Parts

Auto air conditioners are not a standard addition in any type of car. Cars made in 1940s lacked the air conditioning feature as it was not invented by then. With the invention air conditioners and especially the development of these ac's for cars there has been no end to comfort. There were several improvements in technology. Present day auto air conditioners are a real fun to use while driving. The way the humidity, temperature, purity and motion of a place are controlled in a specific area is air conditioning. Auto Air conditioners parts have a precise purpose.

Compressor is like a human heart of the auto air conditioner parts. It is a pump which is connected to the engine of the car. The main function of the compressor is to compress the Freon. There are two sides' intake and discharge. The intake is connected to the evaporator.

Condenser is like a radiator. Its appearance is similar. The main purpose of the condenser is to give away the heat. The condenser is therefore supplied with cooling devices like fan which help to cool the Freon.

Evaporator is found inside the auto air conditioner which helps in absorbing the heat. Other than taking away the heat the other main function of the evaporator is to dehumidify the car. The temperature regulation is done through pressure regulating parts like the orifice tube.

The other auto air conditioning part is the receiver. It has thermal expansion valves which help in pressure regulation. These valves help to remove the gas from the liquid.

Accumulator is another of the auto air conditioner parts which has an orifice tube. It stores the surplus liquid refrigerant Freon. It also prevents the liquid from entering the compressor which may damage the system. Auto air conditioners have also filters. These filters have a very long life and are easy to install and clean. The use of the air filters is to keep the contaminants out of the engine. These air filters need to be replaced on a yearly basis. If the vehicle is driving frequently on dusty roads you need to change the air filters more often.

The Process

In the car the compressor of the auto air conditioning puts the Freon under pressure and it goes into the condensing coils. These coils are found on the front of the radiator of the car. The heat is expelled from the condenser to the outside. By the heat dispersion the refrigerant is cooled and it changes into liquid. Through the expansion valve the refrigerant goes into the evaporator. Here the gas changes into liquid. The cycle is repeated and the car remains cool.

Auto air conditioners are suited for all types of weathers and drives. It is especially suited for long drives which are tiresome. - 21396
