An air conditioner having a defrosting mode of operation is disclosed, in which an outdoor heat exchanger is divided into two heat exchanger units juxtaposed in tandem with each other along the direction of air passage. In defrosting mode, a part of the refrigerant from the compressor is supplied to the upstream outdoor heat exchanger unit deposited with frost, and the rest of the high-temperature high-pressure refrigerant is supplied to the indoor heat exchanger to maintain the room temperature.
