The air that flows through the condenser removes the heat in the high-pressure refrigerant, cooling it down. Learn how your comment data is processed. We shall try to illustrate here the sequential steps on how such a system works. What is Direct Injection & How Does It Work? Your email address will not be published. The chief role of the accumulator is to isolate the compressor from any damaging liquid refrigerant. It serves as a reservoir for the refrigerant while also removing any moisture that may be present in the refrigerant. The components of a car’s AC system is almost same as a room’s AC but there are lots of modification made in an automobile AC to make it compact and to fit it with engine’s component. The compressor connects to the crankshaft via a drive belt. It is one of the most recognizable parts of the modern automotive AC system because it is very easy to check. Cools the air entering the passenger compartment. Cools the air entering the passenger compartment 2. It is important that built-in desiccants remove moisture from the refrigerant. How Does a Car Air Conditioning System Work? There are several types of valves, but they all do the same thing. Evaporator – 5. The rest of the components are in the engine bay. The pressurized liquid refrigerant circulates through the series of tubes located in the condenser. How Does a Car’s Air Conditioning Work? As the gas cools, it condenses and exits the bottom of the condenser as a high-pressure liquid. Many consider the compressor as the heart of the air conditioning system of the car. This is not true. Your vehicle’s compressor, powered by the serpentine belt, compresses the refrigerant into a liquid, putting it into a high-pressure state. Oil under pressure is moving in every hydraulic circuit. Accumulators are used on systems that accommodate an orifice tube to meter refrigerants into the evaporator. At low pressures and temperatures, the refrigerant takes on a gaseous form. Accumulators, like receiver-driers, also remove debris and moisture from a system. As the name implies, the expansion valve allows the expansion of the high-pressure liquid refrigerant coming from the receiver-drier. This site uses Akismet to reduce spam. As the name suggests, it “compresses” the refrigerant so that it turns from a gaseous state into a liquid state. Help us to show you Because the liquid refrigerant in the system is now “hotter”, it turns into its gaseous state again. Controlling the evaporator temperature can be accomplished by controlling refrigerant pressure and flow into the evaporator.

It is the heat sensitive fluid with a very low boiling point that is used in AC as a medium of heat exchange. Note – Between evaporator and compressor a receiver dryer is used that converts the remaining liquid refrigerant from the evaporator into the vapors before sending it to the compressor. The most common refrigerant used in Car AC is the R134-a, also known as Tetrafluoroethane. As such, it draws its power from the engine. The now-hot, low-pressure gaseous refrigerant circulates back to the compressor, ready to begin a new cycle. 1. It is a safety catch used in an automobile or car air conditioning system as there is a chance that instead of vapors some liquid also flows towards the compressor which can damage the compressor, so the receiver dryer is used in between evaporator and compressor to convert that remaining liquid into vapors before sending it to compressor for compression. The automotive air conditioning system is also working on the reverse Brayton or Rankine cycle. This high pressure and the low-temperature refrigerant is then sent to expansion valve which in turn releases the pressure from the refrigerant and convert it into its original state. Well, read on. Vehicles are found to have primarily three different types of air conditioning systems. The article here covers the basic AC processes that accomplish the function of cooling the car's passenger compartment. A weak or dead battery will leave you stranded, while a healthy car battery will perform the functions it is designed to perform. Because the refrigerant is cooler, heat moves from the air and into the refrigerant. Refrigerant – 7. Heat can make your car unbearable to drive, which is why air conditioning was introduced by Packard in 1939. 4. Save my name and email in this browser for the next time I comment. Never operate AC with heater on. This leads to the creation of a cooler refrigerant while also maintaining the integrity of the system. Condenser – 3. A desiccant removes moisture that may be present in the refrigerant.
