  • Air conditioner and method for performing oil equalizing operation in the air conditioner
    Patent number: 7222491
    Abstract: An air conditioner including an outdoor unit including a first compressor and a second compressor connected in parallel to the first compressor, an outdoor unit connected in parallel to the outdoor unit, the outdoor unit including a first compressor and a second compressor connected in parallel to the first compressor, the outdoor units being connected in parallel to indoor units, the compressors being connected by first-compressor oil equalizing tubes and second-compressor oil equalizing tubes to feed surplus oil in the compressors, the oil equalizing tubes being connected by an external oil equalizing tube, wherein oil equalization is performed by collecting lubricant oil in the first compressor of the outdoor unit, pressurizing the collected lubricant oil by a discharge pressure of another compressor connected in parallel to the first compressor in the same outdoor unit, that is, the second compressor, and feeding the pressurized lubricant oil into the first compressor or second compressor of the other out
