Heat transfer modelling of screenhouses

摘要

Several mathematical models to represent the behavior o the inside temperature of screenhouses were developed. Thesemodels take into account different screenhouse configurations as well as the fact that the roof can be built of a single or double layer of cover. The influence of four types of commercial screens (Lumite 32 and 50, and Tildenet 32 and 50) on inside screenhouse temperatures was analyzed. The concept of cooling through water spray was mathematically represented. Experimental data on real screenhouses was obtained at the Benin station of the International Institute of Tropical Agriculture (IITA-Benin), Republic of Benin, Africa.
