Closed Loop Cooling Tower Design

A closed circuit cooling tower or dry cooling tower involves no contact between the air and the fluid being cooled.

Closed loop cooling tower design.

Closed loop cooling tower or closed circuit cooling towers are one of the methods of heat transfers. Closed circuit cooling tower closed loop cooling tower operates during a manner the same as standard cooling towers except that the smart heat to be rejected is transferred from the method fluid to water and close air directly through a heat exchange coil. The pumping head determination procedure for the open tower piping loop differs from the conventional closed. This tower has two separate fluid circuits one in which the fluid is recirculated on the outside of the second circuit which is a bundle of tubes through which the hot water is flowing.

Closed loop cooling tower closed circuit cooling tower operates in a manner similar to conventional cooling towers except that the sensible heat to be rejected is transferred from the process fluid to water and ambient air directly through a heat exchange coil. In a counterflow closed circuit cooling tower design the flow of the air is in the opposite direction of the spray water. Static height not considered for pump selection in closed loop. Cooling tower pumping and piping.

Some types of closed loop equipment may still require freeze protection of some sort but all open loop cooling towers must be equipped with basin heaters a drain back design or a recirculation system for idle periods in freezing conditions. Bac leads the industry in the design and manufacturing of closed circuit cooling towers with the most efficient and cost effective units with both water and. Cooling towers winter operation free cooling 371 16 kb. They are hybrids that pass the working fluid through a tube bundle upon which clean water is sprayed and a fan induced draft applied.

The cooling tower is factory mounted on an epoxy coated steel sub frame with fork slots and lifting eyes. Other configurations are available if a steel legs to elevate the tower is required for your project. 15 ton cooling tower 01a whaley open loop cooling tower no sub frame this unit is an evaporative open loop induced draft cooling tower system which is typically installed outdoors. In bac s counterflow closed circuit cooling towers air travels vertically up through the unit while the spray water travels vertically down over the coil.
