Abstract

The invention provides a refrigeration system and an air conditioner. The refrigeration system comprises a compressor, a condenser, a throttling device and an evaporator which are arranged sequentially; the refrigeration system further comprises a motor cooling loop; the motor cooling loop comprises a mixing injector which is arranged between the condenser and the evaporator; the mixing injector mixes a high-temperature high-pressure cooling medium from the condenser and a low-temperature low-pressure cooling medium from the evaporator into a mixed cooling medium and ejects the mixed cooling medium to a cavity of the motor of the compressor; and the mixed cooling medium cools the motor and then flows into the evaporator. According to the refrigeration system, the refrigeration capacity per unit is increased, the refrigeration cycle coefficient is increased, and an energy-saving effect is realized further; and at the same time, the refrigeration system can operate more stably.

Description

technical field [0001] The invention relates to the technical field of low-temperature refrigeration, in particular to a refrigeration system and an air conditioner. Background technique [0002] In the refrigeration system, the motor drives the compressor to do work. The motor is the power source of the entire circulation system and is also a high-speed running part in the system. The high-speed running rotor will generate a lot of frictional heat, which requires the system to provide cooling capacity to cool the motor. Cooling to ensure the reliable performance of the motor and the service life of the motor. [0003] In the prior art, the cooling scheme of the motor in the refrigeration system is to take the refrigerant from the condenser, depressurize and lower the temperature through the throttle valve, and cool the motor in the motor cavity. Because this cooling solution uses electronic expansion valves for throttling and pressure reduction, the operation is not very s...
