Design ,Construction and Performance Test of Industrial Water Cooling Tower

Abstract

A cooling tower is a device used to lower the temperature of a water stream by rejecting waste heat to atmosphere. It is also known as a heat rejection device where it will lower the temperature by extracting waste heat to the atmosphere though the cooling of a water stream. Generally, the cooling tower may use the evaporation process of water to remove waste heat to atmosphere thus it will lower the working fluid to near the wet-bulb air temperature. Commonly cooling tower is widely used in the process industry for employing water by using re circulated cooling water systems. The cost for this process is inexpensive and very dependable on removing low grade heat from process. In this experiment, the objective are to determine the correlation of water to air mass flow ratio with the increasing water flow rate and to determine the cooling load effect, the effect of different flow rates on the wet bulb approach. Besides that, this experiment also carried out to estimate the evaporation rate of water from the tower. This experiment was carried by using three variable that are heating load, blower damper and water flow rate. The manipulated variable for this experiment are heating load and blower damper opening while the constant variable is the water flow rate
