How Often Should a Car's Air Conditioning Be Cleaned?

[CollinDella]

Car air conditioning should generally be cleaned once a year. Introduction to Car Air Conditioning: Car air conditioning, short for car air conditioning device, is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to the optimal state, providing a comfortable riding environment for passengers and reducing travel fatigue. Working Principle: The car air conditioning refrigeration system consists of a compressor, condenser, liquid storage dryer, expansion valve, evaporator, and blower. These components are connected into a sealed system using copper pipes (or aluminum pipes) and high-pressure rubber hoses. When the refrigeration system is operating, the refrigerant circulates in different states within this sealed system.
