THERMOSYPHON COOLERS FOR COOLING SYSTEMS WITH COOLING TOWERS

Title:

THERMOSYPHON COOLERS FOR COOLING SYSTEMS WITH COOLING TOWERS

Document Type and Number:

WIPO Patent Application WO/2011/149487

Kind Code:

A3

Abstract:

In one embodiment, a cooling system may include a thermosyphon cooler that cools a cooling fluid through dry cooling and a cooling tower that cools a cooling fluid through evaporative cooling. The thermosyphon cooler may use natural convection to circulate a refrigerant between a shell and tube evaporator and an air cooled condenser. The thermosyphon cooler may be located in the cooling system upstream of, and in series with, the cooling tower, and may be operated when the thermosyphon cooler is more economically and/or resource efficient to operate than the cooling tower. According to certain embodiments, factors, such as the ambient temperature, the cost of electricity, and the cost of water, among others, may be used to determine whether to operate the thermosyphon cooler, the cooling tower, or both.
