This study is on the design and performance evaluation of the active solar heating system with geo-source heat pump as an auxiliary heater. This ZeSH was designed and built in the end of 2003 to develop a 70% self-sufficient solar house in thermal load. This study was carried out both by computer simulation and by experiment. TRNSYS simulation program was used to optimize the solar heating system for ZeSH in KIER. The aim of solar fraction is 80% in heating load. The parametric study, the influence of specially the collector area and the storage volume on the system efficiency, was also carried out by computer simulation. The energy sufficient rate for heating load is 86 and 88% respectively by simulation and experiment which is excessively achieved in design value. |
