Evaporative type cooling tower.

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. In hot dry climates evaporative cooling towers will cool outdoor air and circulate it to a space or building. 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. 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 cooling towers typically cool water to approximately 85 f but may cool as low as 65 f. The principle of operation of cooling towers is very similar to that of the evaporative type of condensers in which the warm water gets cooled by means of evaporation. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate. All premises with cooling towers and evaporative condensers must register with the council under the notification of cooling towers and evaporative condensers regulations 1992.

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. An evaporative cooling tower provides cooling based on a design wet bulb temperature. For chiller systems that utilize a cooling tower heat transfer from the cooling process involves two stages. 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.

Evaporative cooling differs from typical air conditioning systems which use vapor compression or absorption refrigeration cycles. Cooling tower is simply a one type of heat exchange equipment where air water comes in to the direct contact with each other. They are the most economical approach to cool large amounts of water. 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.

If you install any kind of cooling tower or evaporative condenser you have a legal duty to notify us within one month of the installation.
