<P>PROBLEM TO BE SOLVED: To provide a heat pump capable of obtaining fluid to be heated having a temperature exceeding 120°C by utilizing waste heat. <P>SOLUTION: A hybrid heat pump 1 includes a compression heat pump 2 and an absorption heat pump 3. The compression heat pump includes a compression part evaporator 20 for heating and evaporating a first refrigerant liquid Vb by a heat source fluid h1 to attain a first refrigerant gas Va, a compressor 4 for compressing the first refrigerant gas, and a compression part condenser 10 for condensing the first refrigerant gas Va compressed in the compressor to attain the first refrigerant liquid and generating condensation heat. The absorption heat pump includes a first evaporator 40 for heating and evaporating a second refrigerant liquid V1f by the condensation heat generated in the compression part condenser to attain a second refrigerant gas V1r, a first absorber 30 for absorbing the second refrigerant gas evaporated in the first evaporator and heating a medium W to be heated by absorption heat, and a first regenerator 70 for heating and regenerating absorption liquid S1w whose concentration is lowered by absorbing the second refrigerant gas in the first absorber. <P>COPYRIGHT: (C)2012,JPO&INPIT |
