Abstract

The performance of narrow gap vertical mantle heat exchangers with a two-pass arrangement used for pumpedcirculation solar water heaters is reported. A onedimensional heat transfer model of this mantle system has been implemented in TRNSYS based on the mean mantle heat transfer coefficient obtained from the measurements and a standard natural convection correlation for the tank side heat transfer coefficient. The simulated performance showed that a direct coupled system delivered approximately 8 % more energy compared to a mantle system for standard domestic hot water demand in Sydney Australia. However, this reduction in system performance can be outweighed by the benefit of freeze protection provided by incorporating a collector-loop heat exchanger in solar water heating systems.
