摘要： A refrigeration cycle apparatus includes a first compressor 1, which is an expander-compressor unit, and a second compressor 2. A first compression mechanism 11 of the first compressor 1 and a second compression mechanism 21 of the second compressor 2 are disposed in parallel with each other in a refrigerant circuit 30. The refrigeration cycle apparatus is provided with an injection passage 6. A controller 7 controls a first motor 12 of the first compressor 1 and a second motor 22 of the second compressor 2, and an opening of an injection valve 61. The controller 7 performs an optimizing operation for the opening of the injection valve. In the optimizing operation, the opening of the injection valve 61 is brought closer to a fully closed state or closer to a fully opened state while a pressure or a temperature of a discharged refrigerant guided to a radiator 4 through a first pipe 3a is kept approximately constant.

摘要： In an apparatus having a refrigeration cycle, the refrigeration cycle is formed by annularly connecting a compressor, a condenser, an expansion device and an evaporator with one another, the apparatus uses propane, isobutane or ethane as a refrigerant, and uses refrigerating machine oil having less mutual solubility with the refrigerant, and a dryer is provided in the refrigeration cycle for absorbing water. In stead of the dryer, an additive which reacts with water may be included in said refrigerating machine oil. With this arrangement, the amount of the refrigerant can be reduced, and the long term reliability of the apparatus can be obtained.
