To provide a compressor capable of suppressing reduction in efficiency.SOLUTION: An indoor unit comprises: a fan; a casing in which the fan is accommodated; and a heat exchanger 60 which is provided inside of the casing and disposed while enclosing the fan. The heat exchanger 60 includes: multiple fins 17 which are arrayed continuously in a circumferential direction while making surfaces opposite to each other; and multiple coolant pipes which pass the multiple fins 17 and are provided while extending in the circumferential direction. The multiple coolant pipes include: a first conduit in which a coolant is made flow in a first circumferential direction 33A that is one direction in the circumferential direction; and a second conduit in which a coolant is made flow in a second circumferential direction 33B that is an opposite direction of the first circumferential direction 33A. At a starting point of the first conduit, a first coolant inlet 36A is provided for introducing the coolant from the outside of the heat exchanger 60 in the first circumferential direction 33A. At a starting point of the second conduit, a second coolant inlet 36B is provided for introducing the coolant from the outside of the heat exchanger 60 in the second circumferential direction 33B.SELECTED DRAWING: Figure 3 【課題】効率の低下を抑制できる圧縮機を提供する。【解決手段】ファンと、ファンを収容するケーシングと、ケーシング内に設けられて、ファンを囲って配置された熱交換器６０と、を備え、熱交換器６０は、互いの面同士が対向して周方向に連続して配列された複数のフィン１７と、複数のフィン１７を通過し、周方向に沿って延びて設けられた複数の冷媒配管と、を備え、複数の冷媒配管は、周方向のうちの一方向である第一周方向３３Ａへと冷媒を流す第一管路と、第一周方向３３Ａと反対方向の第二周方向３３Ｂへと冷媒を流す第二管路と、を有し、第一管路の始点には、熱交換器６０の外部から冷媒を第一周方向３３Ａに向かって導入する第一冷媒入口３６Ａが設けられ、第二管路の始点には、熱交換器６０の外部から冷媒を第二周方向３３Ｂに向かって導入する第二冷媒入口３６Ｂが設けられている。【選択図】図３
