Automotive Air Conditioning System Theory

The compressor is a pump driven by a belt attached to the engine s crankshaft.

Automotive air conditioning system theory.

The automotive air conditioning system is also works on the reverse brayton or rankine cycle. Emphasis on basic refrigeration cycle and diagnosis retrofit and repair of system malfunctions. The automotive air conditioning system consists a refrigeration. Above 212 f 100 c at sea level air pressure it exists as steam which is a gas.

When the refrigerant is drawn into the compressor it is in a low pressure gaseous form. This gas is the lifeblood of your air conditioning and it is very important to notate here that newer vehicles are very sensitive to the refrigerant level. As like all air conditioning system the aim of automotive air conditioning is to control the temperature and humidity of the atmospheric air and circulate the same in the automobile. Compressor condenser evaporator orifice tube or expansion valve and an accumulator or receiver drier.

Most newer vehicles use r134a which is a relatively safe and easy to handle gas. We ll start with the high pressure side as it leads from the engine to the passenger compartment. The purpose of the system is to remove hot air from the inside of your vehicle. The air conditioning system is made up of the following components.

Theory of automotive air conditioning and heating systems. Water is a common material that can exist in all three states. Your car s air conditioning system works just like a refrigerator or your home air conditioning. Learn more about the repetitive cycle of the system from the list of air conditioner components and the ac parts.

All automotive air conditioning systems are nearly closed loops with a high pressure side and low pressure side. Below 32 f 0 c it exists as ice. It consists of the following components. Prepares student for ase testing.

The lifeblood of your air conditioning system. The purpose of the compressor is to pressurize the air conditioning system and circulate the refrigerant.
