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. |
