Evaporative Type Cooling Tower

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.

Evaporative type cooling tower.

In hot dry climates evaporative cooling towers will cool outdoor air and circulate it to a space or building. For chiller systems that utilize a cooling tower heat transfer from the cooling process involves two stages. The main function of cooling tower is to reject heat of hot water into atmosphere cooling down the water for further reuse there are different types of cooling tower. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate.

Cooling tower is simply a one type of heat exchange equipment where air water comes in to the direct contact with each other. The wet bulb temperature is a type of temperature measurement that reflects the physical properties of a system with a mixture of a gas and a vapor usually air and water vapor. Evaporative condenser the major difference between a cooling tower and an evaporative condenser chiller setup lies in the number of stages required to achieve their cooling effects. Comparison table specialized assistance is available through your local bac representative.

The amount of cool air from the tower is dependent on outdoor humidity the height of the tower. 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. Closed circuit cooling towers provide evaporative cooling for many types of systems and the specific application will largely determine which bac closed circuit cooling tower is best suited for a project. All premises with cooling towers and evaporative condensers must register with the council under the notification of cooling towers and evaporative condensers regulations 1992.

They are the most economical approach to cool large amounts of water. Evaporative cooling towers typically cool water to approximately 85 f but may cool as low as 65 f. Water evaporates as a result of the hot water droplet coming in contact with the air which is being pumped out by means of a fan. An evaporative cooling tower provides cooling based on a design wet bulb temperature.

Since the cooling towers are based on the principles of evaporative cooling the maximum cooling tower efficiency depends on the wet bulb temperature of the air.
