Abstract
A warm-water generating apparatus (1) uses, as a refrigerant, a mixed refrigerant containing at least 1,2-difluoroethylene (HFO-1132(E)). The warm-water generating apparatus (1) includes a compressor (21), a heat-source-side air heat exchanger (24), an expansion valve (23), and a use-side water heat exchanger (22). The water heat exchanger (22) causes the mixed refrigerant flowing therein and first water to exchange heat with each other to heat the first water.
