Evaporative Cooling Tower Design

For most industrial manufacturing electric power generation and even air conditioning needs cooling towers are a critical element of the design.

Evaporative cooling tower design.

Cooling towers work on the principle of heat rejection. This is the 43 tower fan evaporative cooler from comfyhome that doubles as an energy efficient air conditioning source and a regular house fan that oscillates. 0 0714 lb ft3 air specific volume. Moreover since they use 100 outside air for cooling the right evaporative cooling system can improve indoor air quality while reducing overall operating cost and energy consumption content source.

When evaporative cooling is used with supplemental dx cooling it can reduce the dx cooling required. Evaporative cooling differs from typical air conditioning systems which use vapor compression or absorption refrigeration cycles. Cooling tower thermal design manual air density. The required cooling tower design and size will be a function of following values.

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. They are the most economical approach to cool large amounts of water. 14 3309 ft3 lb dry air air enthalpy. Evaporative cooling towers typically cool water to approximately 85 f but may cool as low as 65 f.

An evaporative cooler also swamp cooler swamp box desert cooler and wet air cooler is a device that cools air through the evaporation of water. The towers themselves are enclosed steady flow devices for cooling water by evaporation through direct contact with air. Evaporating water at the top of a cooling tower creates a downdraft of cooler air that can then be circulated to a specific space or area. Design considerations of cooling tower.

In hot dry climates evaporative cooling towers will cool outdoor air and circulate it to a space or building. 46 3774 btu lb dry air download the example file exe1 1 zip this file covers the examples of 1 1 through 1 4. An evaporative cooling tower system capable of achieving these goals has the potential to earn points toward energy optimization credit. They extract heat to the atmosphere through evaporative cooling.

Energy design resources e news april 2010. An evaporative cooling tower provides cooling based on a design wet bulb temperature. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate.
