PROBLEM TO BE SOLVED: To provide a heat exchanger for an air conditioner wherein the amount of dehumidification upon dehumidification operation is increased while suppressing deterioration of performance upon cooling operation and heating operation. SOLUTION: In an indoor heat exchanger having a structure where it is divided into a refrigerant upstream side heat exchanger and a refrigerant downstream side heat exchanger with a two-way valve, which includes a pressure reduction mechanism with respect to the flow of a refrigerant upon dehumidifying operation, taken as a boundary, a fin pitch of a fin group of the refrigerant downstream side heat exchanger is more narrowed than that of a fin group of the refrigerant upstream side heat exchanger to increase a heat transfer area of the refrigerant downstream side heat exchanger. |
