Abstract

DEVELOPMENTS OF LABORATORY COOLING TOWER MODEL

Ajayi I. S.*, Oladimeji E. A. and Fatona A. S.

ABSTRACT

Cooling tower is a device employed to extract heat from either power plants or processes that generate large amount of heat and hence reduce the heat to a barest minimum. In this work a laboratory cooling tower was developed to aid the teaching of cooling tower and also espouse the various operational techniques associated with it. The developed cooling tower was based on the principle of mechanical draft. The fan incorporated has a capacity of 0.5 horse power which induces air from the surrounding and uses same to extract heat from the hot water. A 0.31 horse power pump in accordance with the designed values was incorporated to pump the hot water from the tank to the cooling tower chamber. With estimated values of water mass flow rate of 200 kg/hr and air mass flow rate of 1.33 (kg/hr.) the developed cooling tower efficiency, range and cooling capacity were found to be 64%, 180C and 8.50 (kg/s) respectively. These values of efficiency and range compared well with that for standard industrial cooling towers.
