How to solve the problem of poor automobile refrigeration effect

The methods to solve the poor refrigeration effect of automobiles are as follows: 1. Replace the empty filter element; 2. Clean the empty filter element; 3. Clean the condenser; 4. Refrigerant filling can be handled according to the actual situation.

1. replace the air conditioning core: due to insufficient cooling, it is often necessary to first determine whether the air conditioning core is blocked, resulting in small air volume. If the air cooling degree is enough, but the air volume is not enough, it will feel insufficient refrigeration, which can be solved by replacing the air filter element. 2. Cleaning air conditioning: If the filter element of air conditioning is not blocked, but the air volume is still not large, the air conditioning system has no fault after inspection, which is caused by too much dust in the evaporation box and needs cleaning air conditioning. Generally, it is recommended to replace the empty filter element twice a year, once in winter and once in summer, and clean the empty filter element once every two years. Depending on the frequency of use, it needs to be cleaned in summer, but it doesn't need to be cleaned in winter. 3. Clean the condenser: Dirty condenser is also the reason why air cannot be cooled. The condenser is located in front of the water tank and adjacent to each other for cooling the refrigerant. It is often blocked by some dirt such as cotton wool, which leads to poor heat dissipation, which in turn leads to a decline in cooling effect. Washing the car with a water gun can solve it. 4. Refrigerant filling: If the above problems do not appear, you need to refill the refrigerant. Insufficient refrigerant dosage in the pipeline of air conditioning system will lead to pressure drop, less heat taken away and insufficient refrigeration.
