Compressor cooling system, cooling method and air conditioner

The invention discloses a compressor cooling system and method and an air conditioner, and the cooling system comprises a pressure container which is used for receiving a liquid refrigerant from a condenser in a refrigerant system where a compressor is located and providing the liquid refrigerant as a refrigerant for cooling to the compressor; and the pressurizing component is used for pressurizing the gaseous refrigerant received from an evaporator in the refrigerant system and providing the pressurized gaseous refrigerant to the pressure container so as to increase the pressure of the liquid refrigerant in the pressure container. By the adoption of the compressor cooling system, the technical problems that in the prior art, a compressor cooling system is low in reliability and poor in compressor cooling effect can be solved. 本发明公开了一种压缩机冷却系统、冷却方法及空调，所述冷却系统包括：压力容器，其用于接收来自压缩机所在制冷剂系统中的冷凝器的液态制冷剂，并将所述液态制冷剂作为冷却用制冷剂提供至所述压缩机；增压部件，其用于对接收自所述制冷剂系统中的蒸发器的气态制冷剂进行增压，并将增压后的气态制冷剂提供至所述压力容器，以增加所述压力容器中的液态制冷剂的压力。采用本发明，能够解决现有技术压缩
