PROBLEM TO BE SOLVED: To absorb heat from not only a heat storage device but also outdoor air and contrive the improvement of a heating capacity as well as a performance coefficient by a method wherein a plurality of compressors are provided in accordance with the heat sources of the heat storage device and the outdoor air while the discharging capacity of a compressor at the side of the heat storage device is controlled in accordance with the condensation pressure of refrigerant. SOLUTION: An air conditioner is provided with a refrigerating cycle equipped with a plurality of compressors 1a, 1b in accordance with the heat sources of a heat storage device 12 (an ice heat storage device or the like, for example) and outdoor air. In this case, as the compressor 1b at the side of the heat storage device 12 a capacity control type compressor is used. According to this method, the flow rate of refrigerant is controlled in accordance with the condensation pressure of the refrigerant. A pressure detecting device 15 detects the condensation pressure of the refrigerant and a control device 16 determines the capacity of the compressor 1b based on the detecting result of the pressure detecting device 15. A compressor capacity control device 17 controls the capacity of the compressor 1b based on the determination. Accordingly, the heat of outdoor air can be absorbed during heating operation. |
