Abstract
Three identical DHW (Domestic Hot Water) solar energy systems are experimentally compared in terms of the amount of energy collected during two extended periods. The goal of the experiment is to compare three different modes of operating the systems: (1) a single-pass mode, in which the circulating fluid passes once and only once through the collector; (2) a conventional forced circulation multipass mode, in which storage contents passes many times through the collector during each day, and (3) a thermosyphon mode. It is shown that the single-pass system performs better than the other two, with the multipass system being the worst. The thermal advantage of the single-pass mode is specially significant on days with poor radiation and can be as high as 16%, in comparison with the multipass system, being on the average 7% better. The thermosyphon system is shown to perform slightly better than the multipass, although the 1.4% difference found is within the experimental errors.
