| Abstract | ||
| 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. Keywords: Greenhouse; direct evaporative cooling; indirect evaporative cooling. | ||
