Automotive Air Conditioning System Theory

When the refrigerant is drawn into the compressor it is in a low pressure gaseous form.

Automotive air conditioning system theory.

The air conditioning system is made up of the following components. Prepares student for ase testing. Most newer vehicles use r134a which is a relatively safe and easy to handle gas. The purpose of the system is to remove hot air from the inside of your vehicle.

All automotive air conditioning systems are nearly closed loops with a high pressure side and low pressure side. 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. Emphasis on basic refrigeration cycle and diagnosis retrofit and repair of system malfunctions.

Covers epa requirements on recovery of coolants coolant handling and new refrigerant handling and replacements. Water is a common material that can exist in all three states. Theory of automotive air conditioning and heating systems. We ll start with the high pressure side as it leads from the engine to the passenger compartment.

Below 32 f 0 c it exists as ice. Above 212 f 100 c at sea level air pressure it exists as steam which is a gas. Each of these components serves a different purpose. The automotive air conditioning system is also works on the reverse brayton or rankine cycle.

The lifeblood of your air conditioning system. It consists of the following components. The compressor is a pump driven by a belt attached to the engine s crankshaft. The purpose of the compressor is to pressurize the air conditioning system and circulate the refrigerant.

Theory of air conditioning how air conditioning works governmental regulations system inspection. Learn more about the repetitive cycle of the system from the list of air conditioner components and the ac parts.
