How Does a Car's Air Conditioning Work? Any AC system requires a refrigerant, such as R-134a. Your vehicle's compressor, powered by the serpentine belt, compresses the refrigerant into a liquid, putting it into a high-pressure state. All automotive air conditioning systems are (nearly) closed loops with a high-pressure side and low-pressure side. We'll start with the high-pressure side as it leads from the engine to the passenger compartment:. Compressor: The compressor is a pump driven by a belt attached to the engine's crankshaft. When the refrigerant is drawn into the compressor, it is in a low-pressure gaseous form.

The high pressure liquid instantly transforms to a low pressure gas vapor (35 psi at 32° F or 0° C) which creates the coldness inside the evaporator in which case the blower motor passes air through it and into the ventilation system and into the interior of the car. The Auto Air Conditioning System: Know the Parts You might think of your auto air conditioning system like the engine cooling system. Just as the engine cooling system moves heat from the engine to the air, the air conditioning system moves heat from the cabin to the outside. If you look at the diagram above, you will see the arrows which show the direction that refrigerant flows through your AC system. There are slight variations between some systems, but this diagram is a good overall view of a generic AC system. This setup is typical for most imports and a few domestic cars.

Power Steering Stop Leak. Bosch Iridium Spark Plugs. Understand your car's AC system with this informative video diagram, tracing the refrigerant's path through key components. An A/C dye is put into the system and a UV Black light is used to find where the dye is leaking. Another method of leak detection is to use an A/C sniffer. This is an electronic probe that senses the R134A and will alert the technician when a leak is present. 1. Thermal Expansion Valve (TXV) System The first type of system, the Thermal Expansion Valve (TXV) system, uses a thermal expansion valve (TXV) to provide the pressure drop in the refrigerant. The TXV is a variable control valve located at the entrance of the evaporator. A car air conditioning system consists of a compact version of the components of the normal air conditioner that has an evaporator, compressor, condenser, expansion device, and a fan which are fitted in a car to provide air condition inside the passenger's compartment. This air conditioning system takes power from the engine's crankshaft.

How Does AC Work in a Car? The air-conditioning system in a car works by manipulating refrigerant between a liquid and a gaseous state. As the refrigerant changes states, it absorbs heat and humidity from the vehicle and allows the system to give off cool, dry air. The temperature of the outdoor air, the speed of the fan, and the speed of the car determine the extent of cooling. The cooled vapor becomes a liquid and flows to the bottom of the condenser and then is routed to the dryer/receiver. The dryer/receiver contains a desiccant material that removes water and impurities from the liquid refrigerant.

What is an automobile air conditioning system? A car air conditioning system is a set of components that function together to emit coolness to a car's interior. As earlier mentioned, the automotive air conditioning system works much like the AC system we use at home and office.
