Automotive Air Conditioning System Theory

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.

Automotive air conditioning system theory.

Water is a common material that can exist in all three states. Above 212 f 100 c at sea level air pressure it exists as steam which is a gas. We ll start with the high pressure side as it leads from the engine to the passenger compartment. The lifeblood of your air conditioning system.

It consists of the following components. Emphasis on basic refrigeration cycle and diagnosis retrofit and repair of system malfunctions. The air conditioning system is made up of the following components. Compressor condenser evaporator orifice tube or expansion valve and an accumulator or receiver drier.

Your car s air conditioning system works just like a refrigerator or your home air conditioning. When the refrigerant is drawn into the compressor it is in a low pressure gaseous form. Below 32 f 0 c it exists as ice. Prepares student for ase testing.

Covers epa requirements on recovery of coolants coolant handling and new refrigerant handling and replacements. Theory of automotive air conditioning and heating systems. The purpose of the compressor is to pressurize the air conditioning system and circulate the refrigerant. Most newer vehicles use r134a which is a relatively safe and easy to handle gas.

The automotive air conditioning system is also works on the reverse brayton or rankine cycle. The compressor is a pump driven by a belt attached to the engine s crankshaft. Learn more about the repetitive cycle of the system from the list of air conditioner components and the ac parts. The automotive air conditioning system consists a refrigeration.

Each of these components serves a different purpose. All automotive air conditioning systems are nearly closed loops with a high pressure side and low pressure side.
