Abstract
www.solarenergy.ch Abstract- The basis for system development is accurate and reproducible system testing. Since more than 10 years, the solar energy laboratory SPF is involved in system testing. Many systems have been tested according to different approaches. Well proved to investigate new concepts is the component based method, where dynamic fitting in conjunction with TRNSYS is applied to each of the different components. Variation of components in the systems (e.g. heat exchanger, solar collector) demonstrate further possibilities for improvements. According to this component based method, more than 30 systems have been tested in the last 5 years at SPF. Comparison of different concepts are discussed in order to see advantages and disadvantages of low-flow to normal flow concepts. Also the pros and cons of helix heat exchangers to mantle tanks are discussed by comparing the most efficient storage tanks coupled to identical collectors. 1.
