Open Circuit Vs Closed Circuit Cooling Tower

Difference between closed and open circuit cooling towers.

Open circuit vs closed circuit cooling tower.

Addition of a heat exchanger pump piping etc to the open tower loop brings the initial cost much closer to that of the closed circuit tower system. There is no direct contact between the water to cool down and the air inside closed circuit cooling towers but an additional heat exchanger is however used. Choosing closed circuit cooling towers over this open tower heat exchanger combination may still be a better choice for the following reasons. The water is cooled as it falls through the fill and is then.

I have been recently asked to have a have an old bac cooling tower replaced with little to no down time to the factory. A closed circuit cooling tower or dry cooling tower involves no contact between the air and the fluid being cooled. Closed circuit cooling towers. I am new to the industry so i have very limited knowledge of the subject.

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. 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. An immediate open circuit cooling tower is an encased structure that conveys warm water over a maze like pressing or fill which gives an extended air water interface for warming of the air and dissipation to happen. A cooling tower is a heat exchanger that uses the direct contact with the air to cool down water.

Addition of a heat exchanger pump piping etc to the open tower loop brings the initial cost much closer to that of the closed circuit tower system. Water fee costs a lot by spray and evaporation. Choosing closed circuit cooling towers over this open tower heat exchanger combination may still be a better choice for the following reasons. Closed circuit cooling tower s price is higher than open cooling tower but we still say closed circuit cooling tower s price is lower than open cooling tower.

The cost of closed circuit cooling tower is prohibitive. Cooling towers with piping and plate heat exchanger also exist. Open vs closed circuit cooling towers open vs closed circuit cooling towers engrdesign1856 mechanical op 27 jun 07 11 16. Water source heat pumps industrial processes air compressors weld machine cooling mould water cooling power plant auxiliary cooling furnace cooling transformer cooling closed condenser loops critical systems and systems requiring plume elimination.

Unlike a cooling tower where process water is used as the energy transfer medium and is open to the atmosphere the coil inside a closed circuit cooler isolates the process fluid.
