Car Air Conditioning System Diagram

A car air conditioning system diagram typically includes several major components, including the compressor, condenser, evaporator, expansion valve, and various pipes and hoses that connect them.

The process starts with the compressor, which pumps refrigerant gas (usually R134a) from the low-pressure side of the system into the high-pressure side. The gas then flows through the condenser, where it releases heat and turns into a high-pressure liquid. The liquid then moves through the expansion valve, which reduces its pressure and temperature, causing it to evaporate into a low-pressure gas.

As the gas moves into the evaporator, it absorbs heat from the cabin and cools the air, which is then blown into the cabin by the blower motor. The warm air is then returned to the air conditioning system through the intake ducts and is filtered before it reaches the evaporator.

The refrigerant gas then flows back to the compressor to start the process again. The system also includes a variety of sensors and controls, such as the pressure switches, temperature sensors, and electronic control module, that regulate the system’s operation and maintain a comfortable temperature inside the cabin.

Overall, the car air conditioning system works by removing heat from the cabin and releasing it outside, creating a cooler and more comfortable environment for passengers.
