In this project, systems that use solar energy to provide the users with hot water are considered. An auxiliary heater is used when the solar energy is not able to meet the users’ requirements. The goal in this projects is to maximise the part of solar energy in final energy balances at the same time maximising the comfort. This is described by an optimal control problem and is solved using dynamic models of heat exchangers and the building. These models have been developed and the parameters have been identified on two pilot plants located at the Ecole d’ingenieurs d’Yverdon (EIVD). The one-day weather forecasts, provided on-line by the Swiss Meteorological Institute (SMI), are also used. Two systems are under investigation in this project. The first one is a solar domestic hot water system. The second one is called a combi-system, which provides the users with hot water in addition to heating the building.
