System and method for recycling oil in air conditioner

摘要

Disclosed are a system for recycling oil in an air conditioner and a method thereof. The system comprises: an oil recycling line (40) connected between a compressor (14,16) for compressing a refrigerant and an accumulator (22,24) for dividing a refrigerant into gas and liquid and thereby supplying the gas refrigerant to the compressor, for recycling oil stored in the accumulator to the compressor; an open/close valve (44) installed at the oil recycling line and opening and closing the oil recycling line; and a control unit for controlling the open/close valve (44) and thereby controlling an oil supply from the accumulator to the compressor. According to this, an oil deficiency of the compressor is prevented and thereby a reliability of the compressor is enhanced.
