Automotive Air Conditioning System Theory

Theory of automotive air conditioning and heating systems.

Automotive air conditioning system theory.

Above 212 f 100 c at sea level air pressure it exists as steam which is a gas. Below 32 f 0 c it exists as ice. We ll start with the high pressure side as it leads from the engine to the passenger compartment. When the refrigerant is drawn into the compressor it is in a low pressure gaseous form.

Your car s air conditioning system works just like a refrigerator or your home air conditioning. All automotive air conditioning systems are nearly closed loops with a high pressure side and low pressure side. 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 is also works on the reverse brayton or rankine cycle.

Emphasis on basic refrigeration cycle and diagnosis retrofit and repair of system malfunctions. Water is a common material that can exist in all three states. The compressor is a pump driven by a belt attached to the engine s crankshaft. The purpose of the system is to remove hot air from the inside of your vehicle.

Most newer vehicles use r134a which is a relatively safe and easy to handle gas. 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. Theory of air conditioning how air conditioning works governmental regulations system inspection. The lifeblood of your air conditioning system.

Each of these components serves a different purpose. It consists of the following components. Prepares student for ase testing. 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. Covers epa requirements on recovery of coolants coolant handling and new refrigerant handling and replacements.
