Car air conditioners are generally maintained every six months. Below is relevant knowledge about car air conditioners: Introduction: The car air conditioning system is a device that cools, heats, ventilates, and purifies the air inside the vehicle. It provides a comfortable environment for passengers, reduces driver fatigue, and enhances driving safety. Regular checks of refrigerant and compressor oil: Since the refrigerants used in modern cars are highly permeable, even a well-functioning refrigeration system can experience insufficient refrigerant over time due to prolonged use, leading to reduced cooling efficiency. Therefore, it is important to regularly check and replenish the refrigerant. Car owners can determine if the refrigerant is insufficient by observing the sight glass. The sight glass is usually located on the receiver-drier. During normal and continuous operation of the air conditioner, there should be no bubbles in the sight glass. When the air conditioner stops, brief bubbling may occur, indicating that the refrigerant quality is normal.
