PROBLEM TO BE SOLVED: To resolve a problem in a refrigerating cycle device provided with an injection circuit injecting a gas refrigerant separated by a gas-liquid separator 5 into a compressor 1 wherein performance is deteriorated and reliability of the compressor is deteriorated when a temperature difference between an indoor temperature and an outside air temperature is small since dryness of a refrigerant in the gas-liquid separator 5 becomes small, and a great deal of a liquid refrigerant is injected. SOLUTION: The refrigerating cycle device is provided with an outside air temperature detecting means 21, an indoor air temperature detecting means 22, an opening and closing valve 8 capable of carrying out full closing provided between the compressor 1 and the gas-liquid separator 5 of the injection circuit 9, and a control means for detecting the outside air temperature and the indoor air temperature, and carrying out full closing of the opening and closing valve when the difference between the outside air temperature and the indoor air temperature is a predetermined value or less.
