Description

Technical Field

[0001] The invention relates to the field of compressors, and in particular to a self-cleaning variable frequency air conditioner compressor. Background Art

[0002] The compressor is a driven fluid machine that lifts low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, compresses it by driving the piston through the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. The air-conditioning compressor is the core component of the air-conditioning refrigeration system. Its main function is to compress low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure refrigerant gas, thereby achieving the effect of refrigeration or heating. The working principle of the air-conditioning compressor is to drive the piston to compress the refrigerant through the motor, suck it from the suction pipe, and discharge the high-temperature and high-pressure refrigerant gas through the exhaust pipe after compression. During the refrigeration process, the compressor compresses the refrigerant in the low-pressure zone and sends it to the high-pressure zone, dissipates the heat into the air through the heat sink, and the refrigerant changes from gas to liquid, thereby achieving the refrigeration effect. However, the existing self-cleaning variable frequency air-conditioning compressor will generate large vibrations during operation, resulting in greater noise pollution to the surrounding environment, affecting the user experience, and affecting the stability and service life of the equipment. Therefore, those skilled in the art provide a self-cleaning variable frequency air-conditioning compressor to solve the problems raised in the above background technology. Summary of the invention

[0025] The working principle of the present invention is:

[0026] When using a self-cleaning variable frequency air conditioner compressor, during the operation of the air conditioning system, liquid refrigerant that has not been completely vaporized enters the liquid storage tank 2. Since the liquid refrigerant is heavier than the gaseous state, it will sink to the bottom of the cylinder. The vaporized refrigerant enters the cylinder 11 inside the compressor through the No. 1 L-tube 202 and the No. 2 L-tube 203. By installing the liquid storage tank 2, gas can be prevented from entering the low-pressure compressor, and liquid hammer caused by the liquid refrigerant being sucked into the compressor can be prevented, thereby protecting the compressor from abnormal impact. The liquid storage tank 2 also has certain silencing and filtering functions, thereby reducing system noise, filtering out impurities in the system, protecting the compressor and other system components from damage, and improving the stability and service life of the equipment. A sheet groove 1102 is provided in the cylinder 11, and a card 12 is installed in the sheet groove 1102. A spring 1201 is installed on the side wall of the card 12. Through the damping structure of the spring 1201 and the card 12, the mechanical vibration generated by the operation of the internal cylinder 11 when the compressor is running can be effectively absorbed, thereby reducing noise and reducing the impact of mechanical vibration on the surrounding environment, making the environment quieter and more comfortable.
