<P>PROBLEM TO BE SOLVED: To provide a multiple heat pump-type steam-hot water generation device capable of recovering condensation heat of a refrigerating device which has been discharged to the external and disposed, without effectively utilizing the condensation heat by producing the required steam and hot water by a heat pump circuit constituted by a multiple refrigerant circuit, stabilizing an operation of the refrigerating device, and reducing equipment costs of the refrigerating device to contribute to energy saving. <P>SOLUTION: This multiple heat pump-type steam-hot water generation device comprises a lower order-side refrigerant circuit 3 comprising a first cascade condenser 9 to which the condensation heat of a high-temperature gas refrigerant from an external refrigerating device 2 is introduced, and a high order-side refrigerant circuit 4 connected with the low order-side refrigerant circuit 3 by a second cascade condenser 5, and the water supplied from the external is heated by the heat of the refrigerant circulated in the high order-side refrigerant circuit by a heat exchanger in the high order-side refrigerant circuit, to produce steam or hot water or simultaneously produce both of them. <P>COPYRIGHT: (C)2009,JPO&INPIT |
