AIR CONDITIONER, CAPABLE OF EFFECTIVELY COLLECTING OIL BY SEPARATING THE OIL FROM OIL MIXED WITH REFRIGERANT COMPRESSED BY A PLURALITY OF COMPRESSORS

摘要

PURPOSE: An air conditioner is provided to alleviate an imbalance of oil and to reduce the amount of oil being received in a compressor.;CONSTITUTION: An air conditioner comprises a plurality of compressors(110), an oil separator(160), an oil discharge pipe(192), and a plurality of oil collecting tubes(195). The compressors compress a refrigerant. The oil separator separates oil mixed with the refrigerant compressed by the compressors. The oil separated by the oil separator is discharged through the oil discharge pipe. The oil collecting tubes are branched from the oil discharge pipe, and the oil separated by the oil separator is collected to the compressors through the oil collecting tubes.;COPYRIGHT KIPO 2013
