Automobile air conditioning compressor working principle: mainly through the engine to provide power, the evaporator over the low-temperature low-pressure gas compressed into a high-temperature high-pressure liquid to the condenser. The compressor has two areas, a low-pressure evaporator area, a high-pressure condenser area, the refrigerant flows from the high-pressure area to the low-pressure area, through the capillary tube injection to the evaporator, the pressure plummets, ...

Automotive air conditioning compressor principle of work animation explanation

Automotive air conditioning compressor principle of work: mainly through the power provided by the engine, the evaporator over the low-temperature, low-pressure gas compressed into a high-temperature, high-pressure liquid to the condenser. The compressor has two areas, a low-pressure evaporator area, a high-pressure condenser area, the refrigerant from the high-pressure area to the low-pressure area, through the capillary tube injection to the evaporator, the pressure drops, the liquid refrigerant immediately into a gaseous state, through the heat sink to absorb a large amount of heat in the air. In this way, the air conditioning compressor continues to work, it is constantly low-pressure area at the end of the heat absorbed into the refrigerant and then sent to the high-pressure area emitted into the air.

Air conditioning compressor maintenance to add lubricant method:

1, close the suction shut-off valve, start the compressor for a few minutes, the crankcase in the refrigerant discharged into the condenser, so that the crankcase into a vacuum. Stop the machine and immediately close the exhaust valve, slowly screw down the exhaust valve bypass hole screw plug, the high pressure chamber of the remaining air release. Turn down the bypass hole screw plug of the suction cutoff valve, and install the tapered joint and copper pipe;

2. Prepare the lubricating oil, snap the suction pipe mouth with your finger, and start the compressor to pump out the air in the crankcase. If you find the phenomenon of liquid shock, let the compressor continue to run for 2 to 3 minutes, so that the crankcase is a vacuum state, when snapped the mouth of the finger feel a strong suction that is to stop;

3, the finger snapped the mouth of the tube immersed in oil, immersed in that is to let go of, the oil will be sucked from the pipe to the crankshaft tube, observe the oil level indicator, pointed to the oil level whether the oil level to reach the oil line;

4, remove the copper pipe and the connector, screw the screw threads and the copper pipe. Remove the copper pipe and connector, screw on the screw plug tight, start the compressor to let the crankcase suction air pumped out, when you can not hear the exhaust sound, that is, tighten the exhaust shut-off valve screw plug. Open the suction and discharge valve, refueling work is completed. How long does it take to change the oil of the car air conditioning compressor

The car air conditioning compressor can work normally is not necessary to replace, the car air conditioning compressor is in the air conditioning refrigerant circuit to play the role of compression drive refrigerant. The principle of work is mainly through the power provided by the engine, the evaporator over the low-temperature, low-pressure gas compressed into a high-temperature, high-pressure liquid to the condenser. Compressor has two areas, a low-pressure evaporator area, a high-pressure condenser area, the refrigerant from the high-pressure area to the low-pressure area, through the capillary tube injection to the evaporator, the pressure plummeted, the liquid refrigerant immediately into a gaseous state, through the heat sink to absorb a large amount of heat in the air. In this way, the air conditioning compressor continues to work, it is constantly low-pressure area at the end of the heat absorbed into the refrigerant and then sent to the high-pressure area emitted into the air.
