Common problems with refrigeration compressors (1)

Why should we control the impurity and moisture content in compressors and air conditioning systems?

Impurities entering the friction surface of the moving parts in the compressor pump body will cause abnormal scratches and wear. Impurities entering the solenoid valve, expansion valve, control valve, capillary tube and stop valve in the air conditioning system will block the valve hole or make the valve not close tightly and fail.

The moisture in the compressor and air conditioning system will mainly have several adverse effects:

1. The capillary tube and expansion valve will be blocked by ice, and the evaporator cooling pipe will also freeze;
2. The metal material is corroded and deposits are generated;
3. The valve core is corroded and not closed tightly;
4. The “copper plating” phenomenon occurs on the surface of the compressor pump body parts;
5. Accelerate the deterioration of materials such as insulation materials, refrigerants, and refrigeration oil.
