Open Circuit Cooling Tower Diagram

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.

Open cooling towers discharge heat from water cooled systems into the atmosphere. 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. The cooling tower circuit differs slightly from the basic open circuit in that the discharge piping is connected directly to a distribution basin. 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.

Tradional hvac heating and cooling systems are used in schools large office buildings and hospital. Some towers are furnished with a distribution manifold with nozzles which require additional pressure. The towers themselves are enclosed steady flow devices for cooling water by evaporation through direct contact with air. How cooling towers work diagram pictures principles date.

During this evaporative cooling a small part of the water evaporates while cooling the. Cooling towers work on the principle of heat rejection. Choosing closed circuit cooling towers over this open tower heat exchanger combination may still be a better choice for the following reasons. For most industrial manufacturing electric power generation and even air conditioning needs cooling towers are a critical element of the design.

Open circuit cooling towers. They extract heat to the atmosphere through evaporative cooling. The fluid to be cooled flows inside the coil. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet bulb air temperature or in the case of closed circuit dry cooling towers rely solely on air to cool the working fluid to near.

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. On the other hand the closed circuit cooling towers instead of the filling for temperature transfer we will find a coil. Sometimes an open cooling tower is paired with a heat exchanger to capture some of the benefits of closed loop cooling. 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.

Open circuit cooling towers. 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 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.
