PURPOSE:To perform the energy-saving of a pumping apparatus by generating the electric power source of a driving motor for a water pump by the temperature difference between the hot liquid utilizing natural or waster heat and the chilled liquid of the pumping water itself. CONSTITUTION:Hot liquid 1 is heated by a heat source 4 such as natural energy or waste heat, or waste liquid, is fed to an evaporator 5, and evaporates work liquid 6. The evaporated work fluid 6 is fed to a turbine 7 to drive the turbine 7, and is led to a condenser 9. Thus, the fluid is then condensed by the chilled liquid 1 utilizing the discharge liquid of a water pump P1, and is again returned to the evaporator 5. The electric power source of a generator 8 thus driven by the turbine 7 is supplied to the pump P1 and other drive motor M1 and the like. |
