Closed Circuit Cooling Tower Vs Open Circuit Cooling Tower

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.

Closed circuit cooling tower vs open circuit cooling tower.

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. 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. In a closed circuit cooler process fluid is circulated through coils within the unit. I am new to the industry so i have very limited knowledge of the subject.

A closed circuit cooling tower is also based on the principle of evaporative cooling but the water used by processes or chillers is never in direct contact with the atmosphere. I have been recently asked to have a have an old bac cooling tower replaced with little to no down time to the factory. Cooling towers with piping and plate heat exchanger also exist. Closed circuit cooling towers.

Open vs closed circuit cooling towers open vs closed circuit cooling towers engrdesign1856 mechanical op 27 jun 07 11 16. A cooling tower is a heat exchanger that uses the direct contact with the air to cool down water. Equipment layout manual for cooling towers evaporative condensers closed circuit coolers. Difference between closed and open circuit cooling towers.

Choosing closed circuit cooling towers over this open tower heat exchanger combination may still be a better choice for the following reasons. A closed circuit cooling tower or dry cooling tower involves no contact between the air and the fluid being cooled. 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. 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.

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.
