Abstract: Solar combisystem is a hot-topic since 1998 by the help of broad participation TASK-26 project in Europa and USA. The aim of this study is to determine energetic and exergetic analysis results of implemented solar combisystem in Turkey. Experimental system is built up and internal working parameters, external system parameters are measured between 1 and 31 January 2011. Totally, 544 Wh/day electrical energy is consumed to provide comfort conditions, 86% energy saving is achieved and maximum instantaneous collector efficiency is observed as 52%. The system, is supplied the energy demand that is needed to provide comfort conditions of the space and reached the values of overall system exergy efficiency between 1% and 16%. The values of inlet vertical temperature distribution are found between (20 ± 2°C).

Keywords: energy analysis; exergy analysis; exergy efficiency; floor heating; solar energy; solar combisystems; solar power; Turkey.
