Field test of an advanced solar thermal and heat pump system with solar roof tile collectors and geothermal heat source

摘要

The technological combination of solar thermal systems with heat pumps continues to be a highly topical subject in the market of sustainable domestic hot water and space heating systems. Nonetheless, objective performance test methods are not yet common standard. In this context field tests with six different combined solar and heat pump systems installed in single-and smaller multi-family houses in Germany have been performed under real operating conditions by the ITW/TZS. In this paper a novel heating system comprising solar roof tile collectors and so-called geothermal energy baskets is presented in detail and in-situ monitoring results are shown and discussed.
