Abstract: | This communication presents an analysis of the thermal performance of a hot water system consisting of N collectors in series with a storage tank; forced circulation and withdrawal of hot water by displacement with cold water are built into the thermal model. Two modes of withdrawal of hot water, viz. (i) constant flow rate and, (ii) constant hot water temperature (during the day), have been considered. For a quantitative appreciation of the results, numerical calculations have been made for the two modes of hot water withdrawal corresponding to a typical cold day (26 January, 1980) in Delhi. |
