Experimental Study of the Performance of Cooling Tower

Bhupesh Kumar Yadav, S. L. Soni

Abstract: Cooling tower is an essential component of air conditioning plant, chemical plant etc. It is used to reduce the temperature of hot water stream by using outside air and thus heat is rejected to atmosphere. This paper includes the working principle of cooling tower and a set up is fabricated and various parameters related to cooling tower is calculated i. e. range, approach, effectiveness and evaporation loss. Validation of practical model is done using empirical relation. Various equations i. e. Modified Apjohn equation, Modified Ferrel equation and Carrier equation are provided. Carrier equation is used for determining vapour pressure and thus humidity ratio and finally which can be used to determine evaporation loss.
