THEORETICAL MODELING OF THE CONDENSATION PHENOMENA IN THE DEHUMIDIFIER OF THE SEAWATER GREENHOUSE.

The objective of this study is to develop theoretical models to describe the physical processes of condensation of humid air in the dehumidifier of the seawater greenhouse. The developed models were based on the heat and mass balances according to the thermodynamic model of Nusselt. The models were applied to the dehumidifier of the seawater greenhouse that is located at Al Hail in Muscat, Oman. The saturation temperature of humid air and the heat transfer coefficient of condensation were calculated for each tube along the length of the dehumidifier. The simulated condensate values were compared with that of the actual measured values. The relationships between the amount of condensate and other variables such as the relative humidity, the air dry bulb temperature, the seawater temperature, the humid air flow, the seawater flow and the solar radiation were investigated.
