Abstract
An air conditioner of the present invention includes: an outdoor unit having an outdoor heat exchanger and a compressor installed therein; a plurality of indoor units connected to the outdoor unit and having an indoor heat exchanger installed therein; a four-way valve provided on a discharge part side of the compressor; a refrigerant tube having first to third refrigerant tubes and connecting the four-way valve and the indoor heat exchanger, in which the first refrigerant tube is branched from between the four-way valve and the outdoor heat exchanger such that some of a refrigerant discharged from the compressor is fed into the indoor heat exchanger while bypassing the outdoor heat exchanger, the second refrigerant tube is connected to the four-way valve to feed all of the refrigerant discharged from the compressor into the indoor heat exchanger, and the third refrigerant tube is connected to the second refrigerant tube in parallel; and a heat pump valve provided at the third refrigerant tube to selectively close the third refrigerant tube. The air conditioner includes an outdoor unit that can be applied to simultaneous cooling and heating concurrent type air conditioners and cooling and heating switching type air conditioners through the opening and closing of the heat pump valve.
