Open Circuit Cooling Tower Diagram

They extract heat to the atmosphere through evaporative cooling.

Open circuit cooling tower diagram. An open cooling tower is a heat exchanger that in order to cool down water makes use of the direct contact with the air. Cooling towers work on the principle of heat rejection. The towers themselves are enclosed steady flow devices for cooling water by evaporation through direct contact with air. A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature.

Sometimes an open cooling tower is paired with a heat exchanger to capture some of the benefits of closed loop cooling. The fluid to be cooled flows inside the coil. Some towers are furnished with a distribution manifold with nozzles which require additional pressure. Tradional hvac heating and cooling systems are used in schools large office buildings and hospital.

Addition of a heat exchanger pump piping etc to the open tower. The water is cooled as it falls through the fill and is then collected in a cold water basin below. In addition an annex circuit equipped with a pump is responsible for collecting the water from the pool to take it to the top of the tower where it again precipitates on the. For most industrial manufacturing electric power generation and even air conditioning needs cooling towers are a critical element of the design.

Open cooling towers discharge heat from water cooled systems into the atmosphere. In open circuit cooling towers there is a direct contact between the water to cool down and the air. On the other hand cooling towers are much larger than tradional hvac systems and are used to remove heat from cooling tower water systems in petroleum refineries plants natural gas processing plants petrochemical plants and other industrial processes and facilites. Open circuit cooling towers.

The hot process water is distributed over a fill pack heat transfer media to interface with air blown by a fan through the cooling tower. A direct open circuit cooling tower is an enclosed structure that distributes warm water over a labyrinth like packing or fill which provides an expanded air water interface for heating of the air and evaporation to take place. The cooling tower circuit differs slightly from the basic open circuit in that the discharge piping is connected directly to a distribution basin. Open circuit cooling towers.

Cooling tower spouts are managed to diffuse the water over the fill media that reduces the flow of water and reveals the maximum volume of water covering area desirable for the safest air water connection. How cooling towers work diagram pictures principles date. During this evaporative cooling a small part of the water evaporates while cooling the.
