You might look at the air conditioning compressor as the heart of the air conditioning system in your car. This allows for the creation of drier air in the passenger cabin. If not, ice crystals can form and lead to blockage and mechanical damage. How does it do this? The belt turns a rotor, which has a friction plate attached to it. The compressor used to air condition your car works in a similar way to the one in the refrigerator in your kitchen. The purpose of an AC compressor is to cool the air that is moving through the cabin of your vehicle. We do not recommend DIY fixing and maintenance unless you are a pro. Your car air conditioner is supposed to run quietly, but when it starts to produce noises, Your car’s AC compressor could be failing. This site uses Akismet to reduce spam. Cold air from the receiver-drier moves through the evaporator core. You would know if everything is okay in your car’s AC system if the passenger compartment is already cold within the first few minutes of activation, regardless of how hot it is outside. In this video, I show you how to tell if a car's AC compressor clutch is engaging. How Does a Car Air Conditioning System Work? An air compressor is a trigger to start the AC system and an overseer to keep the cycle going. When the comp… As the name implies, the expansion valve allows the expansion of the high-pressure liquid refrigerant coming from the receiver-drier. The compressor and the clutch are two of the essential parts of the air conditioning system of your car. A damaged or failing compressor will not be able to properly regulate the refrigerant flow in the AC system, and as a result, the AC will not function properly. Looking at the different parts of an automotive AC system, it should already be obvious how such technologies cool the air inside the cabin. Many of the new air conditioning systems and most new luxury automobiles use a clutchless compressor fitted with a compressor control valve. The function of the car ac compressor is to keep the air conditioner blowing cold air. However, there should be a special air compressor to make that notion into reality. Antifreeze is one of the factors that make it possible for people to use cars during cold weather or season. That’s why air compressors exist to make the standard AC system compatible with cars. Well, read on. Whenever you turn on the car AC system, the compressor pumps gaseous or vaporized refrigerant to the condenser. Then, the refrigerant passes the condenser to cool down. What comes out of the AC vents is cold and dry air. The compressor connects to the crankshaft via a drive belt. At the same time, the system collects and drains the condensate. The evaporator looks like a very small radiator with fins and tubes. A belt drive attached to the engine spins constantly, providing energy for the AC compressor. Once the desired temperature is reached, it automatically reduces its capacity to maintain the desired temperature. Your vehicle’s A/C condenser is usually located in the front of the radiator, giving it the … When it is finally filtered, the expansion valve lowers its pressure. The compressor compresses or pressurizes the refrigerant, turning it into a liquid form from its gaseous state. The accumulator removes moisture and dirt from the air that goes throughout the entire AC system. A desiccant removes moisture that may be present in the refrigerant. What happens is that heat moves from the liquid and into the air. It is responsible for keeping the refrigerant flowing and thereby ensuring smooth performance. products! The most straightforward way of explaining the purpose of refrigerant is that it is a type of fluid that turns hot air into cold air. From the air compressor, hot gas is radiated by the condenser. Condenser. For more depth, let’s go over the whole system again to give you a clearer picture of what an AC compressor does. To refresh our memory about the answers to the question “What does an AC compressor do,” the keyword is the refrigerant. Then, the condenser continues depressurizing, cooling, and liquefying it for the dryer. In your car's air conditioning unit, the compressor is kind of like the engine that makes it all work. A fully functioning compressor is required in order for the air conditioning system to provide the best performance in the car and continuously blow out cold air. As you may know, refrigerant liquid circulates within the system and flows to … You need to take proper care of your ac compressor and look for any signs that tell you of a need for repair. It also helps to separate the impurities away from the AC system’s parts. So, in case there is any problem with the compressor, the entire air conditioning system will also be affected. The job of the compressor is to move liquid refrigerant around in a pipe. It is usually located before the radiator. Then, a cycling clutch switch regulates or gauges the temperature inside the evaporator to keep the component from completely freezing. Air conditioner compressors are lifesavers for drivers living in hot climates or only experiencing summer months in cold areas. More about orifice tubes, what these components need is an accumulator, not a dryer. Across from the friction plate is another friction plate attached to the rotor that powers the air conditioner. The A/C is an element in the vehicle that is driven by the engine to increase the pressure and the corresponding saturation temperature. This allows fresh air coming from the outside of the vehicle to come in contact with the liquid refrigerant. The air coming from the passenger compartment gets drawn into the evaporator and blasted through the evaporator core. An air compressor is a machine that uses an electric motor or gas engine to power a device that sucks in successive volumes of air from the atmosphere, compresses (squeezes) each volume of air in a confined place to increase its pressure by making the volume smaller, and then transfers the high-pressure air to a receiver tank, according to the EnergyTechPro educational website of DTE Energy. The different types of auto compressors vary in how they handle air exchanges between the car interior and the A/C system. It is best to get familiarized with the different components of the vehicle passenger cooling system to better understand the process of air conditioning. To know more about lesser known car parts, find out the main functions of bushings, brake calipers, and ball joints. When moisture and refrigerant mix together, they release acidic pollutants around the system. Car air conditioners work to make our rides more comfortable and our journeys a lot more worthwhile. Expansion valve- It is a device used in car air conditioning system to expand the high pressure, low … The AC Compressor starts to work right after the vehicle is started. It works through a sequence of events in a fairly simple process. The AC compressor is the central component of your vehicle's AC system and if your AC compressor is failing, you will not get cool air. We shall try to illustrate here the sequential steps on how such a system works. There would be no cycle, throwing the idea of a system. It is one of the most recognizable parts of the modern automotive AC system because it is very easy to check. It is strategically located behind the dashboard. Kitchenistic helps you find the latest and gratest The A/C compressor ironically sucks refrigerant into an area of low pressure created by varying methods depending on the type of pump system ( such as pistons, scroll vacuum, and rotary vanes) it is then compressed, and actually despite popular belief makes the temperature rise, extracting heat from the rest of the car rather than blowing cool air. The low-pressure liquid refrigerant moves through the evaporator. Among all the components of the modern vehicle AC system, the evaporator is the only one that’s located inside the passenger compartment. An air conditioning compressor clutch gets its power from the flywheel of your car’s engine. The compressor works like a pump. Filtering air is essential to prevent water from entering the air compressor. It is important that built-in desiccants remove moisture from the refrigerant. With a lack of oil, the compressor will not function efficiently and will cause premature wear. On the other hand, it is obvious that something is wrong if it takes too long for the car to get cold. Because the condenser contains a higher-temperature liquid, there is a temperature gradient between the liquid and the fresh air. During the hotter months, the AC compressor has to work harder to maintain the temperature you set. It is also positioned right in front of the radiator. An automotive air conditioning system works a lot like the AC system that you have at home or the office. The AC system’s circuitry is too complicated which has a lot to do with the compressor’s function of pressurizing the refrigerant. At last, the refrigerant enters the evaporator, extremely cold and completely free from moisture. Because the liquid refrigerant in the system is now “hotter”, it turns into its gaseous state again. The car ac compressor is majorly the heart of the air conditioning system. While not a “component” of an automotive air conditioning system, the refrigerant is the lifeline of the system. Because the refrigerant is cooler, heat moves from the air and into the refrigerant. In elementary science, we learned that condensation results from the rapid cooling of hot or warm air.
