Abstract: In an air conditioner that uses a refrigerant mixture containing at least 1,2-difluoroethylene, high efficiency is achieved. In the air conditioner (1), a compressor (100, 200) can be driven without interposing a power conversion device between an AC power source (90, 190) and a motor (70, 170). Thus, it is possible to provide the air conditioner (1) that is environmentally friendly and has a relatively inexpensive configuration.

Abstract: A refrigeration cycle apparatus capable of keeping a LCCP low when a heat cycle is performed using a sufficiently small-GWP refrigerant, and a method of determining a refrigerant enclosure amount in the refrigeration cycle apparatus are provided. An outdoor unit (20) including a compressor (21) and an outdoor heat exchanger (23), an indoor unit (30) including an indoor heat exchanger (31), and a refrigerant pipe (5, 6) that connects the outdoor unit (20) and the indoor unit (30) to each other are provided. A refrigerant containing at least 1,2-difluoroethylene is enclosed in a refrigerant circuit (10) that is constituted by connecting the compressor (21), the outdoor heat exchanger (23), and the indoor heat exchanger (31) to one another. An enclosure amount of the refrigerant in the refrigerant circuit (10) per 1 kW of refrigeration capacity satisfies a condition of 160 g or more and 560 g or less.

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.
