Air conditioner system for compressor shell winding refrigerating agent copper pipe

Abstract

The invention provides an air conditioner system for a compressor shell winding refrigerating agent copper pipe. The air conditioner system for the compressor shell winding refrigerating agent copperpipe is mainly characterized in that part of the refrigerating agent copper pipe connecting an outdoor unit heat exchanger and an indoor unit heat exchanger is spirally and tightly wound on a compressor shell, the spiral refrigerating agent copper pipe can be welded to the steel shell of a compressor adopting a brazing process and can also be bonded to the steel shell of the compressor adopting heat conductive silicone, in the summer refrigerating process, by means of a refrigerating agent flowing through the spiral winding copper pipe on the compressor shell, the temperature of the compressorcan be effectively reduced, the working environment of a compressor motor is improved, and the service life of the compressor motor is prolonged; and in the winter refrigerating process, by means ofthe refrigerating agent flowing through the spiral winding copper pipe on the compressor shell, the temperature of the compressor can be effectively reduced, and by means of heat absorbed by the refrigerating agent from the compressor shell, frosting and icing phenomena can be greatly decreased after the heat is transferred to the outdoor unit heat exchanger, the excess heat can further be transferred to the indoor unit heat exchanger, and energy consumption of an air conditioner is effectively lowered.

Description

technical field [0001] With the continuous improvement of people's living standards, air conditioners have been widely used in a wide range, mainly used for indoor cooling of buildings in summer and heating in winter, but due to the large power consumption, the pressure on environmental protection and energy saving is increasing in today's society However, how to improve the cooling or heating effect of the air conditioner and reduce energy consumption is still a challenge. Background technique [0002] Household air conditioners generally use mechanical compression refrigeration devices. The basic components are: compressor, evaporator, condenser and throttling device, which are connected to each other with copper pipes, and the cavity and pipes are filled with refrigerant. It usually exists in several forms: liquid state, gaseous state and gas-liquid mixture. During the mutual conversion of these states, it will cause heat absorption and emission, which will cause changes ...

AI Technical Summary

Problems solved by technology

When performing heating operation, the low-temperature, low-pressure refrigerant vapor from the outdoor unit heat exchanger (collectively referred to as evaporator and condenser) is sucked into the compressor, compressed into high-temperature and high-pressure gas, and then discharged into the indoor unit heat exchanger, passed through The function of the centrifugal fan is to exchange heat with the indoor air, that is, to dissipate heat and become a refrigerant liquid, and then enter the heat exchanger of the outdoor unit after capillary throttling, pressure reduction, and cooling, and under the action of the axial flow fan of the outdoor unit, it is combined with the outdoor air. When the heat exchange is performed, it absorbs heat and becomes a low-pressure refrigerant gas; when the cooling operation is performed, the electromagnetic four-way reversing valve acts to make the refrigerant circulate in the reverse process of the heating process, and the low-temperature and low-pressure refrigeration from the heat exchanger of the indoor unit The refrigerant vapor is inhaled by the compressor, compressed into a high-temperature and high-pressure gas, and then discharged into the heat exchanger of the outdoor unit. Through the action of the axial flow fan, it exchanges heat with the outdoor air, that is, dissipates heat and becomes a refrigerant liquid, and then passes through capillary throttling and cooling. After pressure and cooling, it enters the heat exchanger of the indoor unit. Under the action of the centrifugal fan of the indoor unit, it exchanges heat with the indoor air, absorbs heat and becomes a low-pressure refrigerant gas, and continues to circulate in this way to achieve the purpose of refrigeration; , or the heating process, the compressor keeps running at high temperature and only relies on the axial flow fan of the heat exchanger of the outdoor unit for cooling. Due to the small size of the compressor, in the hot summer, the cooling efficiency is very low, which may easily lead to high temperature protection and shutdown. And the compressor motor works at high temperature for a long time, which affects its service life. In the cold winter, due to the low ambient temperature, frosting and freezing of the outdoor heat exchanger of the air conditioner often occur during the heating process, resulting in the air conditioner not working properly. work, the heating capacity is reduced, and it cannot even be started. It can only use the cooling mode to defrost or de-ice, which not only causes a waste of energy, but also brings a lot of inconvenience to people's lives.
