Abstract

An air conditioner includes oil balancing pipes that extract lubricating oil stored in an oil separator and each of compressors in which a specified amount of the lubricating oil or more is stored, a distributor that distributes the lubricating oil led from the oil separator and the compressors to a plurality of channels, and oil return pipes that communicatively connect the distribution channels of the distributor and a refrigerant inlet pipe of each of the compressors to return the lubricating oil to each of the compressors.

1 . An air conditioner configuring a refrigerating cycle by an outdoor unit including a plurality of compressors connected in parallel and a plurality of indoor units, comprising:
 an oil balancing pipe that extracts lubricating oil stored in each of the compressors in which a specified amount of the lubricating oil or more is stored;   a distributor that leads lubricating oil liquor from the oil balancing pipe and distributes the lubricating oil liquor to a plurality of channels; and   an oil return pipe that communicatively connects a distribution channel of the distributor and a refrigerant inlet pipe of each of the compressors to return the lubricating oil to each of the compressors, wherein   the distributor is mounted and fixed to the refrigerant inlet pipe in a horizontal attitude along a horizontal portion of the refrigerant inlet pipe of the compressors.   
     
     
         2 . The air conditioner according to  claim 1 , wherein
 the compressors include three units in parallel and   an oil reflux cutoff valve is provided in the oil return pipe into which the lubricating oil is most likely to flow.
