| Abstract: | The effect on the collector efficiency using a heat exchanger is analyzed and a ＂heat exchanger penal factor＂ is determined. Energy equantions in fiat plate solar water heaters with heat exchanger are given. Outdoor tests and analysis have been taken on thermal performance of thermosyphon fiat plate solar water heaters with mantle heat exchangers. Experiment results show that average daily efficiency of thermosyphon fiat plate solar water heaters with mantle heat exchangers is lower than that of thermosyphon flat plate solar water heaters without heat exchangers, but higher than that of all-glass evacuated tubular solar water heaters. |
