摘要： PURPOSE:To improve comfortable characteristic by a method wherein a demand control device is connected to an outdoor device, an operating capability of an air conditioner is controlled by an outdoor control device and then a demand control is performed. CONSTITUTION:As a consumed electrical power of an air conditioner 1 exceeds a specified value set in such a manner that the value does not exceed a contract electrical power with an electrical power company, a demand control signal is transmitted from a demand control device 5. A signal receiving device 6 detects this signal and transmits a command of starting a demand control operation to an outdoor control device 7. The outdoor control device 7 stores an operating frequency of a compressor 8, then decreases the operating frequency and also decreases an operating capability. With such an arrangement, the air conditioner 1 merely decreases its operating capability even during a demand controlling operation and enables either its cooling or heating operation, resulting in that a variation in room temperature during a demand controlling operation is also reduced and the comfortable feeling characteristic can be improved.

摘要： PURPOSE:To omit a labor hour of resetting in the case of operating an air conditioner after recovery by storing an operating state of the conditioner at the time of power interruption, automatically sending stored data at the time of recovering the interruption, and deciding a control after the interruption of the conditioner is recovered. CONSTITUTION:At the time of power interruption, a building monitor controller 1, a repeater 2, a centralized controller 7, and an air conditioner 8 are turned OFF, but stored data is held by a memory mechanism 5 in the repeater 2. At the time of recovering the interruption, the data held in the mechanism 5 is transmitted to the controller 7 through a transmission line 10 by a transmitting mechanism 6, further transmitted to the conditioner 8 through a transmission line 11 thereby to recover the conditioner 8 to a state before the interruption. Thus, the restart of the conditioner 8 can be automatically conducted after the recovery in the case of the interruption, and a labor hour of resetting the operation of the conditioner 8 after the recover can be omitted.
