| description | In order to cool a coil of an electric motor (20) of a turbo compressor (10) with a simple configuration, a turbo compressor is provided in a refrigerant circuit (70) that performs a refrigeration cycle and compresses a refrigerant. A refrigerant passage (56) through which a refrigerant flows and a plurality of injection ports (57) through which the refrigerant is injected from the refrigerant passage (56) toward coil ends (24, 25) of the electric motor (20) are formed in bearing retainers (51, 52) that support a drive shaft (26) connected to the impeller (30) and the electric motor (20) by means of a bearing (40), and the injection ports (57) are formed so as to be dispersed in the circumferential direction of the bearing retainers (51, 52).
为了利用简单的结构对涡轮压缩机(10)的电动机(20)的线圈进行冷却，在设置于进行制冷循环的制冷剂回路(70)且对制冷剂进行压缩的涡轮压缩机中，在利用轴承(40)支承与叶轮(30)和电动机(20)连结的驱动轴(26)的轴承保持架(51、52)形成供制冷剂流动的制冷剂通路(56)、以及从制冷剂通路(56)朝向电动机(20)的线圈末端(24、25)喷射制冷剂的多个喷射口(57)，在轴承保持架(51、52)的周向上分散地形成喷射口(57)。 |
