Abstract
Multi-type air conditioner including a plurality of compressors, a plurality of temperature sensors mounted in the plurality of compressors for sensing temperatures in the compressors respectively, and an equalizing pipe in communication with the plurality of compressors, for uniform distribution of oil among the plurality of compressors according to the temperatures sensed at the plurality of temperature sensors respectively, thereby distributing oil among the compressors uniformly at an exact time point at which the oil is distributed among the compressors non-uniformly, not only to permit improvement of the performance of the compressors, but also to permit improvement performance of the air conditioner having the compressors.
