Air conditioning compressors also have "lubricating oil"

When the air-conditioning compressor is working, there are many internal parts rubbing against each other, so it also needs lubricating oil to lubricate. This kind of oil is resistant to low temperature and is generally called refrigerating oil. The lubricating oil of the compressor does not need to be changed regularly.

But in some cases we need to add lubricating oil to the compressor. For example, the leakage of the air-conditioning pipeline leads to the lack of refrigerant. At this time, there will be a lot of oil stains near the leakage point. This is because part of the lubricating oil also leaks when the refrigerant leaks. In this case, it is necessary to properly supplement a part of compressor lubricating oil after maintenance.

What are the types of automobile air conditioning compressors?

The displacement of the fixed-displacement compressor increases proportionally with the increase of the engine speed. It cannot automatically change the power output according to the demand for refrigeration, and has a relatively large impact on the fuel consumption of the engine. Most of its adjustment is through collecting the temperature signal of the air outlet of the evaporator. When the temperature reaches the set temperature, the electromagnetic clutch of the compressor is released and the compressor stops working.

The function and working principle of automobile air conditioning compressor

The automobile air-conditioning compressor is the "heart" of the automobile air-conditioning refrigeration system. Its function is to maintain the circulation of the refrigerant in the refrigeration system, suck in the low-temperature and low-pressure refrigerant vapor from the evaporator, and compress the refrigerant vapor to increase its pressure and temperature. The refrigerant vapor is delivered to the condenser.
