Closed Loop Cooling Tower Design

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.

Closed loop cooling tower design.

The pumping head determination procedure for the open tower piping loop differs from the conventional closed. Flow friction loss h closed loop piping circuit. The cooling tower is factory mounted on an epoxy coated steel sub frame with fork slots and lifting eyes. 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.

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 or closed circuit cooling towers are one of the methods of heat transfers. 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. A closed circuit cooling tower or dry cooling tower involves no contact between the air and the fluid being cooled.

Equipment layout manual for cooling towers evaporative condensers closed circuit coolers. 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. Open tower system pump head requirements. Static height not considered for pump selection in closed loop.

Cooling towers winter operation free cooling 371 16 kb. Other configurations are available if a steel legs to elevate the tower is required for your project. In a counterflow closed circuit cooling tower design the flow of the air is in the opposite direction of the spray water. 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.
