Summary
A simplified numerical code for thermal analysis of a helical heat exchanger for use in long-term thermal energy storage in soil was developed. The model was verified for a particular case for which an analytical solution was available from the literature and was validated with experimental data obtained from field experiments. The differences between predicted and measured data were in the range of ±1°C, which is considered satisfactory for engineering design purposes. The model was prepared for use with an personal computer and thus provides a convenient and reliable design tool for such a system. The computer code may be easily modified for the study of the influence of incorporating phase-change material elements in the storage well.
