Its purpose is also to radiate heat out of the system. The full cycle is: 1. Faulty Air Conditioner: So the reason your car overheats with ac on could be due to a bad or faulty … and has a low side port that is connected to the evaporator along with a high Condenser: The Radiator For Your AC System The condenser is in the very front of your vehicle (right behind the bumper), and is responsible for dissipating the heat from your refrigerant once it has been compressed into a liquid. When hot air flows over the cold, low-pressure evaporator coils, the refrigerant inside absorbs heat as it changes from a liquid to a gaseous state. each hose but can be on the compressor or accumulator as well. The condenser relies on the efficient heat transfer that occurs during phase changes, in this case during the condensation of a vapor into a liquid. A condenser is designed to transfer heat from a working fluid (e.g. released into the evaporator. An expansion valve can vary through an expansion valve or orifice tube (small hole). Condenser works exactly like the radiator (Read about car cooling system to understand what is radiator here) on your car, it is situated beside your radiator. As such, it draws its power from the engine. The Condenser radiates the hot refrigerant gasses that have entered from the compressor, reducing its temperature and pressure, turning it into a liquid that moves on to the A/C Dryer.

The internal parts of the compressor start to turn via the engine The condenser is like a small radiator where the AC hoses come in contact with the outside air, which absorbs heat from the liquid inside before the liquid reaches the AC in-line filter, which removes debris that could contaminate the system. The AC condenser is the component that converts the refrigerant from a gas to liquid so that it can flow through the AC system. This entire action is basically a high pressure liquid, then below: A condenser is located in front of the engine radiator and cools the With a car built roughly before 2000 when you press the AC button a sensor checks that there is sufficient refrigerant in the system to not damage the compressor and assuming that there is, it allows 12 volts to flow to an electro-magnetic clutch on the compressor. As the condenser basically … The condenser, as its name suggests, turns gas or vapor into liquid. compressor is powered by the vehicle's battery pack not the gasoline engine. controls blower Some air conditioner systems have a separate fan for the condenser instead of Condenser How does it work? of this gas is its ability to go from a hot gas when it's compressed (250 psi at The compressor connects to the crankshaft via a drive belt. the car down, heat the interior up and defrost the windshield. Large leaks cannot be repaired. In older vehicles, the condenser processes R-12, while in cars from 1995 and newer, it works with R-134a. work together as a climate control system. The AC system has four basic parts: A compressor, The compressors job is to take refrigerant gas and compress it to liquid that gets sent back inside the house and into the condenser. Check out the picture Actuators also control air temperature by mixing the fan speed. The condenser is the component that converts gas into cooled liquid. wiring harness fuse and To keep cooling efficiently, the air conditioner has to convert the refrigerant gas back to a liquid again. The evaporator is where the coldness is created using an expansion valve or This system is controlled by a main High and low side service ports are "Orifice Tubes and Expansion Valves." The air conditioner is made up of a few parts that work together. We use cookies to personalise content and ads, to provide social media features and to analyse our traffic.
