Abstract

Cooling tower is a type of direct contact heat exchanger, inside of which heat is withdrawn from
water to air. In this research experimental study of the performance of forced draft counter flow
cooling tower at different conditions and different operating parameters. The study was conducted
for different water inlet temperature, different water flow rate, different air flow rate, different
injection holes diameter, different interval distance between injection holes and different types of
packing. The results obtained indicate an increase cooling tower efficiency with the increase of
water inlet temperature, air flow rate, interval distance between injection holes while it is
decreased with the increase of injection holes diameter and water flow rate. The packing of metal
mesh has highest efficiency. The efficiency of cooling tower with metal packing is higher than that
with plastic cells by 5.6%, with that of Kraft paper by 40.4% and with the case of no packing by
51.8 %. However, the packing metal mesh is highest in pressure drop of other the types.
