Development of CFD Model for Estimation of Cooling Effect of Fog Cooling System in Greenhouse

Development of CFD Model for Estimation of Cooling Effect of Fog Cooling System in Greenhouse

Protected Horticulture and Plant Factory 11(2): 93-100

ISSN/ISBN: 2288-0992

This study was carried out not only to develop CFD model for numerically simulating fog coolingsystem but also to verify the validity of the developed model by data measured in fog cooling green-house. In addition the developed model was applied to investigate the effects of spraying water tem-perature, spraying water amount, spraying interval and evaporation percentage on the performanceof the fog cooling system. According to the simulation results, the temperature differences between themeasured and predicted temperatures at each measurement point were 0.1~1.4oC in case of no shad-ing and 0.2~2.3oC in case of shading. The humidity differences were 0.3~6.0% and 0.7~10.6%, respec-tively in the cases of no shading and shading. Because the predicted data showed a good agreementwith the measured ones, the developed model is supposed to be able to predict the cooling effect of thefog cooling system. The performance of fog cooling system was greatly influenced by spraying wateramount, spraying interval and evaporation percentage, but it was not influenced by spraying watertemperature.
