On Modeling Greenhouse Air-Temperature: an Experimental Validation

This work presents an improved procedure for directly predicting air temperature in agricultural greenhouses to provide a quantitative assessment of high or low temperatures. The used dynamic model deals with the heat transfer during four days inside a greenhouse in Tunisia focusing on the season, the location, the structure of the greenhouse and obviously the weather conditions: wind speed, outside temperature, solar radiation, relative humidity…The results are obtained by experimental validation. The used greenhouse model shows the effectiveness of the procedure which has been successfully implemented using the MATLAB /Simulink environment.
