![]() The compressor looks like a pulley attached to a belt-driven engine. In this article, we’ll take a closer look at the role that air conditioning compressors play in vehicle air conditioning systems. This creates a cool windshield in the warmer months and a clear windshield in the colder months. Its main role is to pressurize (compress) the vehicle’s refrigerant to the required pressure, activating heat transfer characteristics and changing the temperature. Without them, the entire air conditioning system would not be able to perform its primary function of creating cold air in the vehicle. Car CompressorĪlthough a vehicle’s air conditioning (AC) system is made up of many components, the AC compressor serves as one of the central components that create the circuits needed for the system. This is how the new cycle takes place and you can get cool, dry, and fresh air. After the process, when the liquid refrigerant in the air conditioner becomes hot, it returns to a gaseous state.Īt this high temperature, the gaseous low-pressure refrigerant recirculates and returns to the compressor. During this process, the condensate is also collected and drained). This process also removes moisture from the air and allows you to enjoy fresh and dry air. ![]() So far, the temperature of the refrigerant is low and the outside heat can be converted to cold air.įans near the passenger seat help cool the car by blowing cold air through the vents. The air from the car is sucked into the evaporator and enters the evaporator core. The converted refrigerant then moves to the evaporator. This process reduces the overall hydraulic pressure and allows it to move to an evaporator (another component of the air conditioning system). ![]() The refrigerant that has already cooled flows into the expansion valve or orifice tube. The desiccant removes moisture from the air and refrigerant, producing a cooler refrigerant while maintaining the system. The refrigerant then moves to the receiver dryer or accumulator. This allows the refrigerant to convert the high-pressure liquid refrigerant mist into a low-pressure liquid refrigerant mist before it enters the evaporator. The orifice tube is conical and restricts the flow of refrigerant. Fans can enjoy air conditioning in the passenger area. It absorbs the heat of the car and converts it into steam to convert it into a liquid refrigerant. The evaporator is behind the air conditioner and looks like a heat exchanger. The flush pressure before the refrigerant is sent to the evaporator. As the name implies, it controls expansion and reduces pressure. The expansion valve helps high-pressure expansion by sending a cold liquid refrigerant through the condenser. When adjusting the temperature of the vehicle to low or high, the liquid refrigerant supplied by the compressor must withstand the convective force of the radiator fan or another fan. CapacitorĪ capacitor is a small device that controls condensation. Liquid refrigerant allows air to flow through the condenser. Increases the pressure of the refrigerant and converts the vapor refrigerant into a liquid refrigerant. ![]() The air conditioner compressor is called the heart. Keeping Your Engine Cool: A Guide to Understanding and Managing Coolant Loss 1. However, the car is smaller than the room, so many changes have been made to make it compact enough to fit inside your car. F.A.Q Components Comprising A Car Air Conditioning SystemĪ car air conditioner has almost the same components as a room air conditioner.Let’s dig in and understand how the air conditioning system which includes the compressor functions. All you have to do is turn on the air conditioner and the compressor does the rest. Pressure acts here and the internal temperature changes. This is where the thermodynamic process of maintaining the temperature in the car compartment is involved. At the end of this cycle, it is in a cold gas state inside the evaporator, at which point outside air is blown, cooled, and then sent to the cabin. The air conditioning system in your car works by circulating the refrigerant, converting it from a gas to a liquid, and then back again. Have you ever wondered how the AC in your car keeps you cool during the summer and heated up in the winter? Well, let’s discuss all about the AC system and specifically about the main component which is the car compressor. ![]()
