A MICROCLIMATE MODEL-BASED ENERGY CONSUMPTION PREDICTION MODEL FOR GREENHOUSE HEATING
An energy consumption prediction model for greenhouse heating was developed based on a greenhouse microclimate simulation model. This model can simulate greenhouse microclimate and predict the energy consumption of greenhouse heating using the climate data outside of the greenhouse and crop information. Experimental data of crop transpiration and greenhouse microclimate were used to determine the crop parameters in the greenhouse microclimate simulation model, and actual data of heating energy consumption of two Venlo-type greenhouses in Shanghai for three winters (from October to next April of year 2001, 2002 and 2003) were used to test the model. The results show that the predicted results agree well with the actual greenhouse energy consumption. Based on the results obtained in this study, it is concluded that this model can give satisfactory predictions of greenhouse energy consumption in subtropical China.
