Abstract

The invention provides a motor and an air conditioner comprising the same. The motor is provided with a main shaft, a water inlet, a water outlet, a water channel, a refrigerant inlet and a refrigerant outlet, wherein a rotor is sleeved outside the main shaft; a stator is sleeved outside the rotor; a casing is sleeved outside the stator; an air gap is formed between the rotor and the stator; the water inlet and the water outlet are arranged on the side wall of the casing; the water channel is arranged on the inner wall of the casing and / or the outer wall of the stator and surrounds the stator; both ends of the water channel are respectively connected with the water inlet and water outlet; and the refrigerant inlet and the refrigerant outlet are arranged on the side wall of the casing and are communicated with the air gap. When the motor and the air conditioner are used, the water inlet of the motor is communicated with a cooling water inlet of a condenser, the water outlet of the motor is communicated with a cooling water outlet of the condenser, the refrigerant inlet is communicated with an air escaping pipe of a flash evaporator, and the refrigerant outlet is communicated with an evaporator. According to the motor and the air conditioner, the energy loss during the throttling depressurization caused by an existing cooling scheme is reduced, the consumption of refrigerating output is reduced, the refrigeration circulating coefficient is improved, and the effect of energy saving is achieved, so that the device works more stably and reliably.

Description

technical field [0001] The invention relates to the field of low-temperature refrigeration, in particular to a motor and an air conditioner including the motor. Background technique [0002] In the refrigeration system, the motor drives the compressor to do work. The motor is the power source of the entire circulatory 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 to the motor. Cooling to ensure the operational reliability of the motor and the service life of the motor. [0003] The cooling scheme of the motor in the conventional refrigeration system is to take the liquid refrigerant from the condenser, depressurize and lower the temperature through the throttle valve, and then 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 stable and...
