摘要: In research literature, little attention has been applied to the effect of vent openings on greenhouse climates during cooling and dehumidification processes with natural ventilation, which would provide guidelines for management. To address this problem, a 3D CFD model was successfully designed based 11-span plastic greenhouses. The validated measured air temperature relative humidity, then used investigate effects configuration opening size climate. simulations show that affects microclimate patterns spatial temporal variations internal Meanwhile, time, humidity process. Finally, assessments ventilation performance highlight roof plus side is most suitable summer cooling, while winter...
