  • Method and system utilizing steam turbine and heat pump
    Patent number: 4093868
    Abstract: Discharge cooling water from the condenser of a steam turbine is pumped through the chiller of a refrigeration machine operating as a "heat pump" during heating duty, thus improving the efficiency thereof from that obtained when using water supplied to the chiller at a lower temperature. Evaporation of the refrigerant in the chiller removes heat from the water supplied thereto, whereby the water temperature is closer to that of the source from which it is taken for use in the turbine condenser.
