Abstract
A heat exchanger includes a plurality of refrigerant flow paths separated by a distributor and is configured to allow a refrigerant inflow amount to each of the plurality of refrigerant flow paths to be adjusted by a pressure loss in a corresponding one of a plurality of capillaries connected between the distributor and the plurality of refrigerant flow paths. Inner diameters of the plurality of capillaries are limited to two types. An inner diameter of one type of the plurality of capillaries having a larger inner diameter is 1.3 to 1.6 times larger than an inner diameter of an other type of the plurality of capillaries having a smaller inner diameter.
