Abstract
The purpose of this study was to shorten the uncultivated period from about 5-6 months to 2 to 3 months. The uncultivated period of 5-6 months was due to midday temperature in the UAE soaring up to 47℃ and the high solar radiation causing problems in crop cultivation. This study intended to compare the effect of reducing high temperature and cooling load of greenhouse through simulation with covering material, external shading, and fan & pad evaporative cooling system to be applied to the UAE smart farm and use it to select equipment capacity such as chiller and cold storage tank. The average indoor illuminance and the peak cooling load were compared according to the type of covering material and the shading rate. When a fan & pad system was applied, the peak cooling load was reduced by 42.9% or 69.4% compared to the typical glass greenhouse (case 1) when the fan & pad system efficiency was 60% or 80%, respectively. It is expected to reduce the capacity of equipment for heat sources such as chiller and cold storage as much as the peak cooling load reduction.
