Background

Principle of screw type water chiller: the screw type water chiller is named as a screw type water chiller because a compressor is a screw type, and the unit is a gas refrigerant coming out of an evaporator; after adiabatic compression by a compressor, the state is changed into a high-temperature and high-pressure state. The compressed gas refrigerant is cooled and condensed in a condenser at equal pressure, is changed into a liquid refrigerant after being condensed, and is expanded to low pressure through a throttle valve to be changed into a gas-liquid mixture. The liquid refrigerant at low temperature and low pressure absorbs the heat of the cooled matter in the evaporator and is converted into gaseous refrigerant. The gaseous refrigerant re-enters the compressor through the pipeline and starts a new cycle. The four processes of the refrigeration cycle are the main working principle of the screw type water chiller, and with the rapid development of the economy of China, the screw type water chiller as a compressor for rotary motion requires a much higher rotating speed than a piston compressor so as to be directly driven by a gas turbine and not generate surge. The heat dissipation of the screw machine on the market at present generally depends on an air cooling mode, when the screw machine runs and works for a long time, the temperature of the screw machine can be sharply increased, so that the motor of the screw compressor is in a high-load running state for a long time, the exhaust temperature of a unit and the temperature of the motor are increased, and the temperature of a motor cavity must be reduced in order to protect the motor of the screw compressor from being burnt out.
