Dynamic modeling of the environment in a naturally ventilated, fog-cooled greenhouse

Abdel-Ghany, Ahmed M.; Kozai, Toyoki - In: Renewable Energy 31 (2006) 10, pp. 1521-1539

A dynamic simulation model for heat and water vapor transfer in a naturally ventilated, fog-cooled greenhouse was developed to predict the temperatures of air, plant, cover and floor surface and the relative humidity in the greenhouse. Transpiration and evaporation were also predicted. An...
