Abstract [en]

This work was a part of IEA Solar Heating & Cooling Program (IEA SHC) Task 26 research, at Solar Energy Research Centre, Högskolan Dalarna. The purpose of this study work was to optimise an existing Swedish solar heating system (#12) using simulations on TRNSYS/Trnsed program. This system has an advanced controller and a store with four heat exchangers: two for the collector loop and two for preparation of hot water. Simulation model has been created as TRNSYS/Trnsed program before this project started, and this program was used to optimise the performance of the model. The boundary conditions for the system optimisation were: climate Zurich (Switzerland), single family house 60 [KWh/a], 10.0 [m2] collector area and stor volume 730 L. No additional costs were to be allowed. The optimisation process include a sensitivity analysis of all relevant parameters in the system. Based on this, a series of different system variations were chosen as possible improvements before the final optimised solution was chosen. An improved performance of the whole system was determined by finding proper inlets, outlets height of connections for the space heating and domestic hot water loop without using any extra material. The results show that for the conditions studied it is not worth to have upper collector heat exchanger in the simulation model so one extra heat exchanger and three valve have been deducted from the combisystem #12. However, one of the features of this system is its attempt to make optimal use of varying radiation conditions and such conditions were not possible to study in this work as only hourly weather data were available. In addition, a study on material demand for this system as well as a similar system, #11 of the IEA SHC Task 26. This data was used to calculate the energy pay-back time for the two systems. It can be used as the basis for possible future LCA studies
