What Components Make Up a Car Air Conditioning Refrigeration System?
2 Answers
A car air conditioning refrigeration system consists of a compressor, condenser, receiver-drier, expansion valve, evaporator, and blower. The method for cleaning a car air conditioning system is as follows: 1. Start the engine and fully open all windows; 2. Set the air conditioning to external circulation with the fan speed at level 3; 3. Open the hood and use your hand or a piece of newspaper to test the air intake, locating the suction point of the air intake; 4. Remove the car air conditioning filter and shake the air conditioning cleaner well; 5. Press the cleaner button and spray the cleaner into the evaporator from the suction point of the air intake; 6. Turn off the air conditioning and let it sit for 5 to 10 minutes; 7. Turn on the air conditioning, set it to external circulation with the fan speed at level 3, and spray the remaining cleaner into the evaporator; 8. Wait for 5 minutes, then switch the air conditioning to internal circulation; 9. After another 5 minutes, set the air conditioning to external circulation with the fan speed at level 4.
The car air conditioning refrigeration system is quite fascinating to me. It consists of several core components, including the compressor, which acts like a water pump in the engine, pressurizing and circulating the refrigerant; the condenser, usually located near the front radiator, is responsible for dissipating heat and converting gaseous refrigerant into liquid; the expansion valve controls the refrigerant flow, allowing it to expand rapidly and cool down; the evaporator inside the cabin absorbs heat from the air and blows out cold air; and the receiver-drier filters out moisture and impurities to ensure stable system operation. Pipes connect all these parts to transport the refrigerant. When using the air conditioning, it's important to keep the condenser clean to avoid dust clogging, which can affect cooling efficiency. R134a is a commonly used refrigerant, but if it leaks, the system won't cool, and you'll need to visit a shop for inspection and refilling, ensuring a cool ride throughout the summer.
