| Abstract:
In order to calculate the CO2 and heat demand in greenhouses, a simulation model is composed of a greenhouse climate submodel and a crop submodel. The purpose of the model is to use it as a management system, which can be consulted for decisions on investments in CO2 and heating equipment. The greenhouse climate submodel calculates the conditions inside the greenhouse on the basis of outside weather data and specified setpoints for the greenhouse climate. It also calculates the demand for heat and the necessity for ventilation. Both these factors are related to the CO2 fluxes to the greenhouse. The crop submodel calculates leaf photosynthesis, crop photosynthesis, dry matter production and fresh weight production. As yet, the production of a tomato and of a cucumber crop can be simulated. | |
