<p>A heat exchanger 11 has a plurality of paths P as refrigerant paths, and at least one of the plurality of paths P has a coexistent path P, in which both of a parallel flow portion R1 where refrigerant flows from a heat transfer tube 15 of one of the tube rows L to a heat transfer tube 15 of a tube row L which is on a downstream side of the one tube row L in terms of an air flow direction A, and a counter-flow portion R2 where refrigerant flows from a heat transfer tube 15 of one of the tube rows L to a heat transfer tube 15 of a tube row L which is on an upstream side of the one tube row L in terms of the air flow direction A, exist in use both as a condenser and as an evaporator.</p> |
