| Summary: | This paper introduces the realization and application of a physicaily-based mathematical model of solar heating systems. The model was realized in TRNSYS 16 simulation environment which is well recognized and frequently-used in scientific researches of transient thermal processes. The mode! is flexible that is it can be easily adapted to a wide range of particular solar heating systems and is a good tool for analyzing and developing them. As an application the model was adopted to the particular solar heating system at the campus of Szent István University, Gödöllő and a new, energetically-based control was evolved and compared with the generally used on/off control method which operates with fixed temperature differences. Based on the relevant simulations it is shown that compared to the ordinary control the energetically-based control provides remarkable savings in auxiliary heating energy. This result should be valid for any systems similar to the particular one in Gödöllő. |
