COOLING WATER SUPPLY SYSTEM AND BINARY GENERATOR WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a cooling water supply system which can stably supply cooling water for a water-cooled chiller even in a region with scarce water resource and to provide a binary generator with the cooling water supply system.SOLUTION: A binary generator comprises: a separator 3 which separates high temperature high pressure geothermal water introduced from a production well 1 into steam and hot water; an evaporator 7 which evaporates a heat medium by exchanging heat with the steam separated by the separator 3; a steam turbine 9 which is driven by steam of the heat medium evaporated by the evaporator 7; a generator 9a which is driven by the steam turbine 9 to generate power; a condenser 16 which condenses the heat medium introduced from the steam turbine 9 by exchanging the heat with cooling water; a cooling tower 20 which cools the cooling water to be supplied to the condenser 16; and a storage section 11 which supplies the cooling tower 20 with the cooling water. In the binary generator, geothermal water introduced from the production well 1 is used as the cooling water.
