Car ac system diagram

We have some excellent threads on the forum about airconditioning, notably car AC systems, obviously!

If you are someone who has always been curious about how car AC works, continue reading below for a deeper look into air-conditioner theory, system components and system operation. The air-conditioning system in a car works by manipulating refrigerant between a liquid and a gaseous state. As the refrigerant changes states, it absorbs heat and humidity from the vehicle and allows the system to give off cool, dry air. To change the refrigerant between a liquid and a gaseous state, the air-conditioning system works to control pressure and temperature. In the past, automotive air condition systems used R as the refrigerant. R aka Freon is a very effective CFC-based chlorofluorocarbon refrigerant that is not flammable and not poisonous to humans.

When it comes to car air conditioning, most people take it for granted. Without your air conditioner, driving in warmer climates like Australia will become an unbearable experience for the common driver. Have you ever wondered how car air conditioning works? Well the car air conditioner has pretty much worked the same way for its entire existence in the modern world and that is, it cools and removes humidity from the air. The compressor is connected to an evaporator which cools the air as it passes through. The cooled air is then sent through vents in your car cabin. All car air conditioning systems are fully closed loops. In one full loop, it changes the state of matter 3 times with a high-pressure side and a low-pressure side. The refrigerant is drawn into the compressor as a low-pressure gaseous form. Once the gas is in the pump it is put under extreme pressure psipsi and is forced out to the condenser. Compressors cannot compress liquids, only gasses. The condenser is basically a radiator, and it serves a similar purpose to the one in your vehicle, to draw heat out of the system. The refrigerant enters the condenser as a high-pressure gas from the compressor. The process of pressurizing the gas and moving it to the condenser creates heat, but air flowing through the fins and tubes of the condenser cools the refrigerant down condenses changing the state of the gas to a high-pressure liquid. The liquid refrigerant is now a high-pressure liquid and nearly ready to cool the car.

In essence that is all, in reality it is a bit more complex, but not by much. MMI programs prepare graduates for careers in industries using the provided training, primarily as marine technicians.

.

For this reason, it is very important to keep the passenger cabin cool. A car cooling setup means a lot on hot days. So, this article is for you, both for AC technicians and for non-techie guys. This article provides a comprehensive overview of the seven basic car air conditioning system parts in a clear and practical manner. The main purpose of the auto air conditioning system is to make the internal temperature of the air lowered and comfortable for occupants.

In the United States, the car air conditioner is a necessity for every car during the hot summer months. Many passengers do not know how their air conditioner works and take it for granted. This article will explain the basic principles of how automotive air conditioning works. By understanding how the ac works, you can appreciate the engineering that goes into making this life-saving device. Air conditioners made life easier and more comfortable for car occupants. In this powerful guide, you will learn comprehensively how car air conditioning units work, and the scientific principles which cool the refrigerant, and condensation, explained in easy words.

These front seals do not wear out quickly. Mostly all mechanical so I hope most folks can follow! Actually, Jack told me that it was pretty unusual to see problems with the Ford AC compressors. A tell tale of the leak!!! Once the gas is in the pump it is put under extreme pressure psipsi and is forced out to the condenser. On my Jeep I replaced the bearing and on an earlier Jeep I had to replace the whole clutch too as it was worn out. Have a look at this diagram. Automotive Service Technicians and Mechanics, viewed June 2, Here, the system changes from the high-pressure side to the low-pressure side. I have pulled off one part.

You probably don't think of your car's air conditioning system very often.

The gas moves out of the evaporator and out of the passenger compartment of the car, taking the heat with it. Road debris and dirt may reduce airflow, causing system malfunction.
