| Summary: | In this study, the energy and exergy analysis of a hot water preparation system, which is a boiler assisted vacuum tube solar collector, has been conducted. The obtained data were compared with reported results in the literature related to direct operating principle system. Average energy and exergy efficiencies of the experimental system were founded 12% and 0.3%, respectively. The average energy and exergy efficiencies of the vacuum tube solar collectors were founded 13.6% and 1.3%. Energy and exergy efficiencies of the vacuum tube solar collectors, which have indirect operating principle, are lower than direct system working with solar collectors. Maximum exergy loss has occurred in the vacuum tube solar collectors and followed it boiler and pump, respectively. |
