Abstract

The invention provides an air-conditioning system and a compressor oil temperature regulating device used therein. The compressor has a shell, including a heat exchange device. The heat exchange device is attached to the shell, and the heat exchange device It has heat exchange inlet and heat exchange outlet. The air-conditioning system provided by the present invention and the compressor oil temperature regulating device used therefor are equipped with a heat exchange device, and according to the discharge temperature of the compressor, an appropriate heat exchange medium is passed into the heat exchange device, and the temperature of the heat exchange medium is used to control the temperature of the heat exchange device. The mixture of the compressor is heated or cooled to achieve the purpose of effectively adjusting the temperature of the mixture, and the refrigerant is passed into the heat exchange device, and when the mixture is cooled, the temperature of the mixture can be used to vaporize the liquid refrigerant, thereby increasing the compression The suction superheat of the machine can be controlled, and the problem of liquid hammer of the compressor can be prevented without increasing the volume of the 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...
