چکیده
|
This study investigates experimentally, the effect of direct and indirect evaporative system on the temperature and relative humidity distribution inside a greenhouse. experimental tests on a full- scale greenhouse of sizes 0.9 m x 0.55 m x 2.4 m (w x h x l) were conducted in october 6 university, 6 october city, giza, egypt at summer rush hours were used to obtain spatial distribution of air-temperature. measurements of temperature distributions at about 63 points inside the greenhouse. one of the main conclusions is that experimental results were preserve the temperature variation below 30^оc during the day rush hours, especially in the area designated for the growth of plants inside the greenhouse.
