    摘要: A refrigeration apparatus (1) comprises a compressor (2), a condenser (4, 6), an expansion mechanism (5), and an evaporator (6, 4). A refrigerant containing R32, and refrigerator oil for lubricating the compressor (2) are used in the refrigeration apparatus (1). An acid scavenger added in an amount of 1.0 wt% to 5.0 wt% is blended in the refrigerator oil. The amount of air mixed into the refrigeration apparatus (1) is controlled to 500 ppm or less relative to the amount of filled refrigerant. The amount of water mixed into the refrigeration apparatus (1) is controlled to 300 ppm or less relative to the amount of filled refrigerant. A discharged-gas temperature of the refrigeration apparatus (1) is controlled to 120°C or less.
