Abstract
An air conditioner that can perform defrosting efficiently while heating or the like is continued even if the air conditioner is configured by one outdoor unit is obtained. In an air conditioner in which an outdoor unit having a compressor that pressurizes and discharges a refrigerant, a plurality of outdoor heat exchangers that exchange heat between outside air and the refrigerant, and a four-way valve that switches a channel on the basis of an operation form and a plurality of indoor units, each having an indoor heat exchanger that exchanges heat between the air in a space to be air-conditioned and the refrigerant and an indoor throttle device are connected by a pipeline so as to configure a refrigerant circuit, a bypass pipeline that divides the refrigerant discharged from the compressor so as to allow the refrigerant to flow into each of the outdoor heat exchangers connected in parallel by a pipeline, a plurality of outdoor third opening/closing valves that pass or shut off the refrigerant from the bypass pipeline to each of the outdoor heat exchangers, and a plurality of outdoor second opening/closing valves that pass or shut off the refrigerant from the indoor unit to each of the outdoor heat exchangers are disposed in the outdoor unit.
