1. The air conditioning pipes, condenser, and evaporator need to be cleaned when a new compressor is installed. The internal air conditioner pipes should be separated and cleaned. A special cleaning solution should be poured into the condenser and evaporator of the pipes, allowed to soak for approximately 20 minutes, and then the filth and cleaning solution should be flushed out simultaneously using high-pressure nitrogen.

2. If the drying bottle is a pipeline filter, it needs to be replaced, and the expansion valve needs to be properly cleaned or replaced.

3. Select only pure refrigerant, please.

4. Add about 450 grams of refrigerant and install a new compressor.

The car air conditioning compressor is the heart of the car air conditioning refrigeration system. It plays a role in compressing and transporting refrigerant vapor.
There are two types of compressors: fixed displacement and variable displacement. According to different working principles, air conditioning compressors can be divided into fixed displacement compressors and variable displacement compressors. The introduction of fixed displacement compressors for automobiles is as follows: 1. The displacement of fixed displacement compressors increases proportionally with the increase of engine speed, and cannot automatically change the power output according to the refrigeration demand, which has a significant impact on engine fuel consumption; 2. It is generally controlled by collecting temperature signals from the evaporator outlet. When the temperature reaches the set temperature, the electromagnetic clutch of the compressor is released, and the compressor stops working; When the temperature rises, the electromagnetic clutch engages and the compressor starts working. The constant displacement compressor is also controlled by the pressure of the air conditioning system. When the pressure in the pipeline is too high, the compressor stops working.
