<p><P>PROBLEM TO BE SOLVED: To provide a heat pump system in which it is not necessary to change the generated outputs of generator even if the total generated output of the generators and a photovoltaic power generating device is larger than a set power. <P>SOLUTION: The heat pump system S comprises a first heat pump device 10, a second heat pump device 20 and a control part C which controls operations, a DC part at the input side of a first inverter 15 and a DC part at the input side of a second inverter 25 are electrically connected to each other, and the control part C controls the operations of the first inverter 15 and the second inverter 25 so that the first inverter 15 converts the set power into AC power and outputs it when the sum of the generated outputs of the photovoltaic power generating device 1 and the first generator 12 exceeds the set power, and the second inverter 25 converts the power of the sum of surplus power corresponding to an excess amount beyond the set power and the generated output of the second generator 22 into AC power and outputs it. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
