<p><P>PROBLEM TO BE SOLVED: To provide a heat pump system which does not require change in generated electric power by a generator even when total generated electric power by the generator and a photovoltaic power generating device is larger than set electric power. <P>SOLUTION: The heat pump system S includes a plurality of heat pump devices 10, 20, 30 and a control part C for controlling operation. Direct current parts on input sides of inverters 15, 25, 35 of the respective heat pump devices 10, 20, 30 are electrically interconnected. The control part C controls operation of the inverters 15, 25, 35 so that the inverter of the heat pump device having individual excess electric power out of the plurality of heat pump devices 10, 20, 30 converts individual set electric power of the inverter into A.C. electric power and outputs it and so that the inverter of the heat pump device having individual allowance electric power converts electric power of the inverter which is a sum of generated electric power by the photovoltaic power generating device, generated electric power by the generator and allocated and distributed electric power into A.C. electric power and outputs it. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
