Automotive air conditioning diagram

Refrigeration cycle used: Vapour compression cycle. The system used for automobile air conditioning works on the same principles that other automotive air conditioning diagram conditioning being used. The major problem associated with automobile air conditioning is running speed of compressor. While installing AC in the automobile, the compressor is mounted above the engine and it is driven by belt drive powered from front end of the engine.

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.

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. Initially, I did have problems putting stuff back together again. Apparently I took our central heating furnace apart when my parents were not looking. They only noticed when it was getting cold in the sitting room, and they had to call in a specialist to put it back together again. These days I do manage a bit better. Usually I manage to put things back together. Would look pretty cool in my garage!! So buckle up and lets rip this compressor apart!! It is going to get a bit technical, if not nerdy. Mostly all mechanical so I hope most folks can follow! I am not going to explain in detail how an AC system works.

A car air conditioning system diagram typically includes several major components, including the compressor, condenser, evaporator, expansion valve, and various pipes and hoses that connect them. The process starts with the compressor, which pumps refrigerant gas usually Ra from the low-pressure side of the system into the high-pressure side. The gas then flows through the condenser, where it releases heat and turns into a high-pressure liquid. The liquid then moves through the expansion valve, which reduces its pressure and temperature, causing it to evaporate into a low-pressure gas. As the gas moves into the evaporator, it absorbs heat from the cabin and cools the air, which is then blown into the cabin by the blower motor. The warm air is then returned to the air conditioning system through the intake ducts and is filtered before it reaches the evaporator. 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. 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. The condensed refrigerant, when changes its state to vapor refrigerant, produce cooling by taking the heat from the surrounding. In other words, the car AC system works on the principle that liquid absorbs heat when they become vapors. When the refrigerant enters the compressor it is pressurized into a high-pressure, high-temperature refrigerant, which is passed through the condenser where it is converted to a liquid state means condensation occurs.

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.

Have a look at this diagram. Thus the compressor shaft starts to rotate. The refrigerant is piped though a dryer to take out any moisture and ends up in the condensor usually at the front of your car, behind or in front of the radiator. The pressure has dropped significantly below atmospheric pressure and hence the name Low Pressure LP Line. The active reference to source is obligatory if you use materials of a site Car Anatomy. It is held in place with a circlip as well. So this where the Fiesta system developed a leak. Now look at the images of the clutch plate, it has corresponding splines. Cancel Changes. RA is more or less the default type of refrigerant these days. Step Inside First of all, you are likely not to be able to get these individual parts very easily. Showing a Chrysler system, it should show the evaporator leaking! Cargado por ppolansky.

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?

Notice the green felt. There are a number of different compressors out there. They only noticed when it was getting cold in the sitting room, and they had to call in a specialist to put it back together again. It was made in Hungary in and it takes RA refrigerant. When disengaged the pulley freewheel freely? As the compressor reduces the evaporator pressure to approximately kPa 25 psi , the pressure switch opens, de-energizing the compressor clutch. It will cause wear and it draws a little power from the engine as well of course. On the bottom you see another black connector mounted on top of the compressor housing. Please enter a password for your user account. RA is more or less the default type of refrigerant these days. When activated the electromagnet pulls it towards the pulley. A compressor will most likely leak in one of three places. Now the liquid has been prepped, it is time to move over to the low-pressure side.
