Abstract

The invention provides an air conditioning system and a compressor oil temperature adjusting device used by the air conditioning system. A compressor is provided with a shell and comprises a heat exchange device, wherein the heat exchange device is attached to the shell, and a heat exchange inlet and a heat exchange outlet are formed in the heat exchange device. According to the air conditioning system and the compressor oil temperature adjusting device used by the air conditioning system, the heat exchange device is adopted, an adaptive heat exchange medium is introduced into the heat exchange device according to the exhaust temperature of the compressor, the temperature of the heat exchange medium is utilized to raise or lower the temperature of a mixture of the compressor, so that the purpose of effectively adjusting the temperature of the mixture is achieved, and refrigerant is introduced into the heat exchange device; and when the mixture is cooled, the liquid refrigerant can be vaporized by utilizing the temperature of the mixture, so that the suction superheat degree of the compressor is increased, and the problem of liquid impact of the compressor can be solved on the premise of not increasing the volume of a gas-liquid separator.

Description

technical field [0001] The invention relates to the technical field of compressor auxiliary equipment, in particular to an air-conditioning system and a compressor oil temperature regulating device used therein. Background technique [0002] In order to control the oil temperature of the compressor and prevent the liquid hammer of the compressor, the existing air conditioner generally adopts the method of adjusting the frequency of the compressor and the opening of the electronic expansion valve to prevent the oil temperature from being too high by returning liquid or reducing the frequency, and using the electric heating belt to control the oil temperature. The bottom of the compressor is preheated to heat the mixture to prevent the oil temperature from being too low. However, the oil temperature is still too high under high temperature conditions or the compressor is running at high frequency, and the mixture oil temperature is too low under low temperature conditions. Co...
