<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 and disposed to the external, 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: The condensation heat of an external freezer 2 is recovered by an exhaust heat recovery heat exchanger 9 of a low order-side refrigerant circuit 3, the recovered heat is distributed to a high order-side refrigerant circuit 4 through a 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 4 by heat exchangers 15, 16 in the high order-side refrigerant circuit 4 to produce steam or hot water, or simultaneously produce both of them. <P>COPYRIGHT: (C)2009,JPO&INPIT |
