PART.1: How the air conditioning system works
The automotive air conditioning system uses the principle that the refrigerant absorbs heat energy when it changes from liquid to gas to achieve the cooling effect. During the compression process, the compressor sucks in the refrigerant gas in a low-temperature and low-pressure state and compresses it into a high-temperature and high-pressure gas. Subsequently, the refrigerant in a high-temperature and high-pressure state enters the condenser and discharges the heat through the heat dissipation process. After passing through the expansion device, the volume of the refrigerant increases, the pressure and temperature drop sharply, and finally absorbs the surrounding heat in the evaporator, thereby reducing the temperature inside the car.
PART.2: What does air conditioning maintenance involve
Inspection cycle: every 12 months
Inspection items: Air conditioning maintenance
The significance of air conditioning system maintenance: The air conditioning filter filters out dust, pollen and dirt particles in the air and then makes it clean. Like all filter elements, it has a limited absorption capacity. At the same time, each air conditioning system has an evaporator. Condensation forms in its fins. Over time, fine Bacteria, fungi and microorganisms settle here. Therefore, the evaporator must be disinfected regularly.
What does air conditioning maintenance involve?
① Visual inspection of all parts
② Function and performance test
③ Replacement of air conditioning filter
④ Disinfection of evaporator when necessary
PART.3: What does air conditioning maintenance involve?
Inspection cycle: every 2 years
Inspection items: Air conditioning maintenance
The significance of air conditioning system maintenance: Even new air conditioning systems have up to 10% refrigerant leakage every year. This is normal, but it will reduce cooling performance and increase the risk of compressor damage. Through the filter dryer, the refrigerant is not affected by moisture and contaminants.
What does air conditioning maintenance involve?
① Visual inspection of all parts
② Function and performance test
③ Replacement of filter dryer
④ Disinfection of evaporator when necessary
⑤ Replacement of refrigerant
⑥ Leakage test
⑦ Replacement of air conditioning filter
