Patent number: 10670340Abstract: In a method for supplying cooling water to a condenser under conditions where an evaporation rate of the cooling water is low during a certain time and is higher during other times, cooling water is delivered from a body of water underlying a cooling tower to the condenser. During the certain time when the evaporation rate of the cooling water is low, a level of the water in the body of water is controlled to a value such that a concentration of a contaminant in the body of water is low, and such that the temperature of the water in the body of water throughout the other times will assure a desired condensate temperature in the condenser throughout the other times. Then, a level of the water in the body of water during the other times is controlled to a value maintaining the low concentration of a dissolved solid and ions.Type: GrantFiled: December 1, 2014Date of Patent: June 2, 2020Assignee: ORMAT TECHNOLOGIES, Inc.Inventors: Dany Batscha, Noa Kalish, Gal Yona, Idan Peled, Avi Ben-Sabat, Ohad Rotem
