The present invention minimizes any increase in the external dimensions of an accumulator even while the volume of the accumulator is expanded, and inexpensively realizes high efficiency and user-friendliness. A compressor (3), an intake tube (4), a discharge tube (5), an air-refrigerant heat exchanger (7), a water-refrigerant heat exchanger (8), an expansion valve (9), and two accumulators (10A, 10B) are accommodated inside a casing (2) of a heat pump hot-water-supply outdoor device (1). These devices constitute part of a refrigerant circuit. The accumulators (10A, 10B) are arranged above the compressor (3) and an electrical component storage box (12). This configuration makes it possible to expand the overall accumulator volume through the plurality of accumulators (10A, 10B), even without increasing the size of the casing (2). Additionally, cooled air, of which the temperature is reduced through coming into contact with the accumulators (10A, 10B), makes it possible to efficiently cool the compressor (3), the electrical component storage box (12), and an inverter module (23), which are arranged below the accumulators (10A, 10B). |
