To provide an air conditioner capable of simplifying a configuration and installation work and having oil separators capable of uniformizing the amount of refrigerating machine oil returned to each compressor of a plurality of outdoor units operated in parallel.
A refrigerating cycle is formed by interconnecting the plurality of compressors in parallel. The oil separator 9 including a cylindrical container 22, an inner cylinder 23 concentrically inserted from a tip of the cylindrical container 22 and opened in the cylindrical container 22, a gas refrigerant inlet pipe 27 for introducing a gas refrigerant to the tangential direction of the cylindrical container 22, a gas refrigerant outlet pipe 35 communicating with the inside of the inner cylinder 23 and a return pipe extracting refrigerant machine oil stored in the cylindrical container 22 and returning the refrigerant machine oil to the compressor is inserted and connected to a refrigerant discharge pipe of each of the compressors 1. An interval between the cylindrical container 22 and the inner cylinder 23 is formed to be the inner diameter of the gas refrigerant inlet pipe 27 or smaller.
