Annual Performance Prediction of Earth-to-Air Heat Exchanger in The Medical Facility
In this paper, an annual prediction method of pre-cooling and pre-heating performance for an earth-to-air heat
exchanger (EAHE) by the unsteady CFD analysis which does not analyze flow fields to reduce the calculation load, are
proposed, and the validity are verified of this analysis in comparison with by long-term measurements. We predict the annual
thermal performance of an EAHE in a medical facility by long-term measurement results. Moreover, the prediction accuracy
of this CFD analysis is verified by comparing the results of annual survey.
