Abstract
This paper describes the performance of a 'load-side' heat exchanger immersed in a stratified tank designed for use in a solar energy space heating and hot water system. A load-side heat exchanger is one that removes energy from the storage tank by passing cool water through the heat exchanger. The measured heat transfer rate versus time is presented as is the calculated effectiveness as a function of the difference in temperature between the storage tank and the heat exchanger inlet. The effect of changing the storage tank temperature definition on the calculated effectiveness is discussed and a method of using time constants to predict the heat transfer rate of immersed heat exchangers in a stratified tank is presented.
