PROBLEM TO BE SOLVED: To provide a refrigeration cycle device improving operation efficiency of a refrigeration cycle by properly controlling a refrigerant amount circulating in the refrigerant cycle, and also reducing costs.SOLUTION: A refrigeration cycle device 1, in which a compressor 23, a first heat exchanger 22 and a second heat exchanger 32 are connected through a refrigerant pipe 10, when causing the first heat exchanger to function as a condenser, adjusts opening of a first expansion valve 25 on the basis of the temperature difference between a first temperature sensor 41 for detecting an outlet temperature of refrigerant flowing out from the first heat exchanger, and a second temperature sensor 42 for detecting a temperature of air flow supplied to the first heat exchanger.SELECTED DRAWING: Figure 1 |
