Abstract:
1. A multi-type air conditioner comprising: an outdoor unit installed outside of a room having a compressor and an outdoor heat exchange mounted therein; a plurality of indoor units, each installed in a room, having an electronic expansion valve and an indoor heat exchanger; a distributor that separates refrigerant from the outdoor unit at a gas-liquid separator and guides separated refrigerant to the plurality of indoor units selectively depending on operation conditions; a first connection pipe that guides the refrigerant from the outdoor unit to the gas-liquid separator in the distributor; a second connection pipe that guides the refrigerant from the distributor to the outdoor unit; and a switching part in the outdoor unit having a first four way valve provided to a discharge side of the compressor that selectively switches a flow direction of the refrigerant flowing in the outdoor heat exchanger, and a second four way valve configured to switch in conformity with switching of the first four way valve to maintain the first connection pipe as a high pressure section where high pressure refrigerant flows, and the second connection pipe as a low pressure section where low pressure refrigerant flows.
