Faults in air conditioning refrigerant and refrigeration oil caused by

Refrigerant and refrigerant oil caused by the failure, for many reasons, including lack of refrigerant caused by excessive cooling, caused by too little refrigerant refrigeration insufficient refrigerant and refrigerant oil contains too many impurities, micro-blocking caused by insufficient refrigeration, air conditioning and refrigeration the system has insufficient cooling water caused by infiltration, the system has led to inadequate cooling air and refrigeration oils cause poor cooling is inadequate.

If too much refrigerant, heat slowly. If there are too much in the repair when added oil, also can make the cooling capacity of refrigeration system decline. Maintenance methods: from the drying tank above the liquid mirror observation. If the car air-conditioning in the operation from the liquid mirror do not see a bit of air compressor is stopped, no bubble, it is certainly too much refrigerant.

If the refrigerant oil added too much, air conditioning system in normal operation, can see more turbid air bubbles from the liquid mirror. If it is too much refrigerant, can be in the low-voltage side air conditioning repair mouth slowly released some.

Everyone has a heart, if the heart stops beating and the life will disappear.Cars are no exception,diagnostic code reader is the heart of the car,therefore, quality is good and bad, directly affects the car's performance and service life.
