This report is part of WP2 – Modelling and Control in TheGreefa project. It describes the development of the CFD model mentioned to predict the microclimate in a greenhouse. The previous scope of using this model to identify suitable sensor positions and locations for air conditioning units is no longer pursued. Instead, this study focuses on the modelling of radiation and humidity. In contrast to the previous report, these complex phenomena can also be validated with measurement data from an experimental greenhouse in Chorfech, Tunisia. Due to these new circumstances, some findings from the simulation for the Wädenswil greenhouse are no longer applicable.
