Automotive air conditioning diagram

Refrigeration cycle used: Vapour compression cycle.

We have some excellent threads on the forum about airconditioning, notably car AC systems, obviously! All detailled in my thread of fiddling with my cars. At the end of this post I will provide links to each repair job. I thought it would be interesting to open it up and get a feel for what is inside. According to my mum I started taking things apart from when I was about 3 years old.

What is the purpose of the drier?

Are these systems to be weight in?

The cycling clutch orifice tube CCOT refrigerant system cycles a compressor 1 on and off in order to maintain the desired cooling. This cycling also prevents evaporator freeze-up. The temperature selector on the control assembly maintains comfort in the passenger compartment comfort. A switch that senses low side pressure as an indicator of the evaporator pressure controls the refrigeration cycle, or the on and off operation of the compressor. The cycling pressure switch is the freeze protection device in the system. The switch also senses refrigerant pressure on the suction side of the system.

You probably don't think of your car's air conditioning system very often. But if it broke down, you'd definitely miss the cool air. So, how does AC work in a car? Automotive air conditioning has been with us longer than you might think. Packard invented automotive AC all the way back in , and in it was the first car company to offer factory-installed air conditioning. Of course, this early system didn't have a thermostat, but it was better than not having anything at all. The idea caught on, and by , more than half of all new cars were sold with air conditioning built in. Eventually, it was determined that the refrigerant used for decades in automotive AC, known as R, CFC, or its brand name Freon , was damaging the ozone layer it's a chlorofluorocarbon. It was banned from being manufactured in the United States and an alternative, called Ra or HFCa, was required for all cars manufactured after A car's air conditioning works by manipulating pressure and temperature to move refrigerant between a liquid and gaseous state.

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. The automotive air conditioning system cleans, dehumidifies, and circulates the interior air of the car cabin. The cooling system consists of different car cooling setup parts located under the hood and inside the cabin.

This is to activate the magnet that pulls the clutch in. With another circlip undone, we can start pulling the compressor body apart. So replacing is often the easiest and cheapest solution. Actually, Jack told me that it was pretty unusual to see problems with the Ford AC compressors. 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. A close up of that electro magnet. As you will see, if they run without pumping the lubrication can become a problem. All rights reserved. The refrigerant gas then flows back to the compressor to start the process again.

In the United States, the car air conditioner is a necessity for every car during the hot summer months.

While all the other parts of the system are located in the engine compartment, the evaporator is in the cabin, usually above the footwell on the passenger side. Especially if you begin to run low on refrigerant. Car manufacturers often use different compressors, so there is also a variety of spare parts out there. Here you see the old and the new compressor. What is Split Air Conditioning System? Same sequence as above, but now I have taken the electro magnet off as well. Published by. With the heat of the shop, I had a good load on the compressor and could watch the operation. Remember Me? This vapour refrigerant is then circulated along with lubricant oil to the condenser. Apparently I took our central heating furnace apart when my parents were not looking.
