Evaporative Type Cooling Tower

An evaporative cooling tower provides cooling based on a design wet bulb temperature.

Evaporative type cooling tower.

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. Comparison table specialized assistance is available through your local bac representative. 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. Evaporative cooling towers typically cool water to approximately 85 f but may cool as low as 65 f.

They are the most economical approach to cool large amounts 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. All premises with cooling towers and evaporative condensers must register with the council under the notification of cooling towers and evaporative condensers regulations 1992. 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.

The amount of cool air from the tower is dependent on outdoor humidity the height of the tower. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate. 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 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.

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. 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. Cooling tower is simply a one type of heat exchange equipment where air water comes in to the direct contact with each other.

Evaporative cooling differs from typical air conditioning systems which use vapor compression or absorption refrigeration cycles.
