A scroll compressor with air preheating effect

Abstract

The invention discloses a scroll compressor with air preheating effect. body, the top inside the shell is the exhaust cavity, the shell on the exhaust cavity is provided with an exhaust hole, and the static scroll is arranged directly below the exhaust cavity, and the fixed scroll and the movable scroll are cross-fitted. The invention adopts the mutual cooperation of the outer ring body, the rotating ceramic tube and the inner ring body. When the rotating ceramic tube sucks in the cold air from the outside, it is affected by the air flow and rolls directly. During the rolling process, it is heated and cooled evenly without whitening on one side. , leading to embrittlement and fracture, the present invention is provided with connecting blocks and gaskets between the rotating ceramic tube and the outer ring body, on the one hand to reduce the impact of vibration on the rotating ceramic tube, and on the other hand as a heat insulation component to insulate part of the heat, Reduce the effect of heat on the upper outer and inner rings.

Description

technical field [0001] The invention relates to the field of air conditioner compressors, in particular to a scroll compressor with air preheating effect. Background technique [0002] When the air conditioner is heating, the gas refrigeration compressor is pressurized by the compressor to become a high-temperature and high-pressure gas, which enters the heat exchanger of the indoor unit (in this case, the condenser), condenses and liquefies and releases heat to become a liquid, and at the same time heats the indoor air, thereby achieving The purpose of increasing the indoor temperature is that the refrigerant evaporates into a gas in the outdoor unit and absorbs the heat in the air, so the evaporation temperature of the refrigerant must be lower than the outdoor temperature. The existing public application number is CN201910418334.3, a scroll compressor The heating device of the machine uses a PTC heating device to preheat the inhaled air, but because it is outdoors, in a c...

[0002] When the air conditioner is heating, the gas refrigeration compressor is pressurized by the compressor to become a high-temperature and high-pressure gas, which enters the heat exchanger of the indoor unit (in this case, the condenser), condenses and liquefies and releases heat to become a liquid, and at the same time heats the indoor air, thereby achieving The purpose of increasing the indoor temperature is that the refrigerant evaporates into a gas in the outdoor unit and absorbs the heat in the air, so the evaporation temperature of the refrigerant must be lower than the outdoor temperature. The existing public application number is CN201910418334.3, a scroll compressor The heating device of the machine uses a PTC heating device to preheat the inhaled air, but because it is outdoors, in a cold environment, the temperature is easy to drop. Use, it is easy to cause whitening and embrittlement on one side, break during vibration, and fragments get stuck in other parts, resulting in poor operation
