Abstract

A first four-channel switching valve (26) of only an ourdoor unit (20A), to which a defrost request is made, is switched by a controller (50), and defrost operation is performed by permitting an outdoor heat exchanger (22) of the outdoor unit (20A) to communicate with the discharge side of the compressor (21).
