The cycling clutch orifice tube CCOT refrigerant system cycles a compressor 1 on automotive air conditioning diagram off in order to maintain the desired cooling. This cycling also prevents evaporator freeze-up, automotive air conditioning diagram. 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.

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.

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. Overall, the car air conditioning system works by removing heat from the cabin and releasing it outside, creating a cooler and more comfortable environment for passengers.

In the shop, I used two methods to overcome this: first, a large fan, if no one else was using it. This expansion reduces the pressure on the refrigerant, so it can move into the evaporator.

Refrigeration cycle used: Vapour compression cycle. The system used for automobile air conditioning works on the same principles that other air 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 condenser is mounted ahead of car radiator. The cooling coil and the blower are usually located under dashboard. Compressor: Low pressure, low temperature R — a vapour refrigerant entering the compressor is compressed to become high pressure, high temperature R — a vapour refrigerant.

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.

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. Since the compressor cannot compress the liquid therefore it must be in gaseous form.

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. Same cycle is repeated again and again, till desired temperature in cabin is achieved. The main difference tends to be whether they have a clutch system or variable or a combination of both. This cycling also prevents evaporator freeze-up. Notice that the clutch plate centre piece has splines on it, that fit on corresponding spines on the compressor shaft. All times are GMT So everything we took off comes from this side. Saltar el carrusel. Which one of the following best describes you? Thanks, if anyone cares to respond. Documentos de Cultura. The evaporator is usually mounted behind your dashboard and tends to be part of the cabinet air circulation system.

The system looks complicated, but it's really quite simple. Once you know how it delivers cold air you will be better informed when problems occur and how to fix them, or understand more on what a garage is telling you when having it repaired.

Get the problem fixed right, the first time. The refrigerant gas then flows back to the compressor to start the process again. As you will see, if they run without pumping the lubrication can become a problem. Your email address will not be published. All detailled in my thread of fiddling with my cars.
