This paper is concerned with the modelling and simulation method used in greenhouse climate control. A bond graph is a topological diagram, clearly representing any kind of physical network. In this case, the bond graph models the heat and vapour flows between compartmented components and the coupling between heat and vapour flow. The bond graph can easily be converted into a differential equation model to be solved, for example, by CSMP. In the present case, however, the bond graph was used as a direct input to an interactive simulation program on a minicomputer. The method was applied to model an experimental greenhouse described by STANHILL et al. 1973.
