What is the pressure of a car air conditioner?
1 Answers
The normal high pressure of a car air conditioner should be between 1.3 to 1.7 MPa (13 to 17 kg per square centimeter or 190 to 250 Lbf), and the normal low pressure should be between 0.15 to 0.25 MPa (1.5 to 2.5 kg per square centimeter or 20 to 35 Lbf). The car air conditioning refrigeration system consists of a compressor, condenser, liquid storage dryer, expansion valve, evaporator, and blower. These components are connected by copper pipes (or aluminum pipes) and high-pressure rubber hoses to form a closed system. During operation, the refrigerant circulates in different states within this closed system, with each cycle comprising four basic processes. Car air conditioner maintenance methods: Comprehensive inspection of the air conditioner: When using the air conditioner for the first time in summer, you should first check the air conditioning system, such as inspecting the refrigerant and whether the air filter is too dirty through the liquid storage tank, and whether there are foreign objects on the radiator. Pay attention to the cleaning of the air conditioner: The air filter should be replaced regularly. Due to the high amount of sand and dust in spring, these can accumulate on the filter, promoting bacterial growth and causing a musty smell in the air conditioner. Additionally, the condenser should be cleaned periodically, and the water tank should be removed for thorough cleaning.
