Abstract

The invention relates to a motor cooling circuit and method of a compressor, and a refrigeration system and an air conditioner. The motor cooling circuit of the compressor includes a motor of the compressor, a refrigeration cycle pipeline in which the compressor is located, a cooling pipeline and a pressurization piece, wherein the cooling pipeline communicates with the refrigeration cycle pipeline and the motor, is used for guiding part of a refrigerant in the refrigeration cycle pipeline to the motor to cool the motor, and the pressurization piece is arranged in the cooling pipeline for adjusting the pressure of the refrigerant in the cooling pipeline. According to the motor cooling circuit and method of the compressor, and the refrigeration system and the air conditioner, through the variable refrigerant pressure of the cooling motor, the refrigerant flow for cooling the motor is adjusted to adapt to the required refrigerant amount under different working conditions.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a motor cooling circuit of a compressor with an adjustable amount of refrigerant, a cooling method, a refrigeration system and an air conditioner. Background technique [0002] The motor of the centrifugal compressor is a high-power, high-speed special motor, and its rated power increases with the increase of the cooling section. At present, the power of the centrifuge motor used for refrigeration in the industry has reached 1300kW. However, due to the copper loss and iron loss of the motor, the motor efficiency cannot reach 100%, and the lost motor efficiency is converted into heat, and the greater the motor power, the greater the heat generation. The overflowing heat will reduce the output power of the motor, and in serious cases will cause the rotor to demagnetize, or even burn the motor. Therefore, motor cooling is a necessary means to ensure the stable operation of the centrifuge...
