What is the principle of air conditioning compressor?
Everyone knows that the center of gravity of air conditioners is the compressor, so the importance of the compressor is naturally self-evident. Today, the decoration home network Xiaobian will introduce the relevant knowledge of the principle of air conditioning compressor , I hope to bring help to friends who want to know !
Air conditioning compressor principle:
1. The air conditioner compressor functions to compress and drive the refrigerant in the air conditioning refrigerant circuit. The working circuit divides the evaporation zone and the condensation zone, and the indoor unit and the outdoor unit belong to a high pressure or low pressure zone, respectively. The compressor is generally installed in the outdoor. The compressor extracts the refrigerant from the low pressure zone and compresses it to the high pressure zone for cooling and condensation. The heat sink radiates heat to the air, and the refrigerant changes from a gaseous state to a liquid state, and the pressure rises. . The refrigerant then flows from the high pressure zone to the low pressure zone, and is injected into the evaporator through the capillary tube. The pressure drops rapidly, and the liquid refrigerant immediately becomes a gaseous state, and a large amount of heat in the air is absorbed by the heat sink. In this way, the machine continuously works, and the heat at one end of the low-pressure zone is continuously absorbed into the refrigerant and sent to the high-pressure zone to be distributed into the air, thereby regulating the temperature.
2. When the air conditioner is in the cooling operation, the low-temperature low-pressure refrigerant gas is pressurized by the compressor and becomes a high-temperature high-pressure refrigerant gas. The high-temperature high-pressure refrigerant gas is released into the medium-temperature high-pressure in the outdoor heat exchanger. The liquid, the medium-temperature and high-pressure liquid is then throttled and reduced to become a low-temperature and low-pressure liquid through a throttling component, and the low-temperature and low-pressure liquid refrigerant is heated to a low-temperature and low-pressure gas in the indoor heat exchanger, and then enters the compressor. Compression, reciprocating cycle.
3. The compressor is the heart of the refrigeration system. Whether it is air conditioning, cold storage, chemical refrigeration process, etc., this important part of the Russian compressor must be guaranteed ! There are many types and forms of refrigeration compressors. There are two types of speed and speed type, of which volume type is the most common.
Air conditioning compressor repair method:
1. Close the suction shut-off valve, start the compressor for a few minutes, and then discharge the refrigerant in the crankcase into the condenser, so that the crankcase is in a vacuum state. After the air conditioner stops, close the exhaust shut-off valve, then unscrew the screw plug beside the exhaust shut-off valve to release the air remaining in the high pressure chamber, then remove the suction plug of the suction shut-off valve and install the taper Connector and copper tube.
2. After preparing the lubricating oil, use your fingers to cover the suction nozzle. Then start the compressor to pump out the air in the crankcase. If the liquid hammer is found, let the compressor continue to run for 2-3 minutes, wait until the crankcase is in a vacuum. At the same time, the finger holding the nozzle feels strong suction and stops.
3. Dip the oil suction pipe that is caught by the finger into the lubricating oil. After releasing the hand, the lubricating oil will be automatically sucked into the crankshaft tube.
4. Observe the oil level indicator and know that the added lubricant has reached the oil level.
5. Wait until the oil is full, remove the copper tube and the screw on the screw, then start the compressor to pump out the inhaled air in the crankcase. Wait until the sound of the exhaust is not heard and tighten the screw plug of the exhaust valve. Finally, open the suction and exhaust shut-off valves, and the work of refueling is completed.
The above is the related knowledge of the principle of air-conditioning compressor introduced by Xiaobian . I hope to bring you reference for your decoration !
