  • THE DEVELOPMENT AND OPTIMIZATION OF COST EFFECTIVE THERMAL ENERGY STORAGE SYSTEMS FOR SOLAR SPACE HEATING BY MEANS OF A MICROPROCESSOR CONTROLLED TEST FACILITY

Abstract

This report describes the results of the three years' research into thermal energy stores for active solar space heating. The project had three major aims:- + Experimental research and development on thermally effective, low cost TES technologies. + Computer modelling of complete solar heating systems to evaluate the potential improvements in annual solar fraction brought about by specific designs in store. + Cost optimisation of solar space heating systems, incorporating annual simulations, to compare the cost effectiveness of specific designs of store over the systems' lifetime and to determine the overall economic viability of active solar space heating. Conclusions: short term active solar space heating is fundamentally uneconomic under current criteria. If installed, however, for the same performance, encapsulated phase change material stores seem to offer significant savings in volume. Alternatively, for stores of the same volume, and less than Im**3, the phase change store gives improved performance at a similar life cycle cost compared with the water store. Stratification in a water store is likely to give only a marginal improvement in performance.
