Abstract

The aim of the present work is to study the effect of evaporative cooling system for greenhouse under humid and hot weather.  A gable roof design greenhouse was covered with old fiberglass glazing for more than 15 years was used. The experiment was carried out for 26 days of continuous data measuring, starting from June 8 to July 3 of year 2010 where the highest outside air temperature was obtained. Greenhouse dimension was 24 m. long, 10 m. width and 4 m. height. The results show that the highest difference of about 10-11 oC. was between cooling pad section and outside air temperature. Meanwhile, the lowest temperature differences were 2-6 oC. between middle section of the greenhouse and cooling pad section. The maximum value of sensible heat transfer was 53 kJ/s between outside and evaporative pad.
