Özet

The aim of this study is to determine the relationship that is found among the velocity of the air passing through the pad, the obtained decrease at the temperature of the air passing the pad and the cooling efficiency at the cellulose based evaporative cooling pad, and be of help to the people who designed and operate these systems. In this study, cellulose based evaporative cooling pad (CELdek (R)7060-15, Munters AB, Kista, Sweden) was used and the tests conducted were completed at 2 periods. Air velocities were determined as 0.5, 1.0 and 1.5 ms(-1) at the first period, and 0.75, 1.25 and 1.75 ms(-1) at the second period. The water flow rate at the air velocities, chosen for both periods, was selected as 4 Lmin(-1)m(-2). As a result of the research, it was determined that it was not possible to make a mathematical connection among velocities of the air passing through the pad, obtained decrease at the temperature of the air passing the pad and the cooling efficiency. However, it can be said that the most appropriate air velocity for the pad used in the test should be higher than 0.5 ms(-1) and lower than 1.5 ms(-1).
