What needs to be done for car air conditioning maintenance?
1 Answers
Car air conditioning maintenance mainly consists of the following three aspects: 1. Regularly check the refrigerant and compressor oil. The refrigerant used in cars has strong permeability, even in a well-functioning refrigeration system, prolonged use can lead to insufficient refrigerant, resulting in reduced cooling efficiency. Regular checks and replenishment are necessary. 2. Clean the condenser surface. The cooling efficiency of the air conditioning system is related to the cleanliness of the condenser's cooling fins. Dirt, insects, and other debris covering the condenser surface can reduce heat dissipation efficiency, thereby affecting cooling performance. Moreover, restarting the air conditioning under such conditions can cause excessive pressure and overheating in the system, severely impacting the compressor and related components. Therefore, it is essential to professionally clean the condenser fins periodically. 3. Clean the evaporator surface. The evaporator surface temperature is very low, and when it encounters relatively warm outside air, condensation occurs, which is why the evaporator is designed with a drain pipe. The damp environment inside the evaporator and ventilation ducts, along with surface dust, provides a breeding ground for bacteria, leading to biological decay and unpleasant odors. Cleaning the evaporator helps improve these odors.
