ESOLS Water cooling Tower Demonstration Unit is stand-alone unit used to study the closed- circuit cooling and heat dissipation. In water cooling towers the water to be cooled is sprayed over a wet deck surface. Water and air come into direct contact in the counter-flow. The water is cooled by convection. Some of the water evaporates and the evaporation heat removed further cools down the water. In this Unit Water is heated in a tank and transported by a pump to an atomiser. The atomiser sprays the water to be cooled over the wet deck surface. The water trickles from the top to the bottom along the wet deck surface whilst air flows from the bottom to the top. The heat is transferred directly from the water to the air by convection and evaporation. The evaporated water volume is recorded. The air flow is generated by a fan and adjusted using a throttle valve. The cooling column is transparent allowing clear observation of the wet deck surface and the trickling water.
The unit has Touch LCD display for visualization of process and the measurements. The Unit is also connected to Software for computer connectivity and data analysis. The Touch screen and computer software is included in the package.
