Description: For several years, we have been developing models for ground loop heat
exchangers, heat pumps, and other related components. These models are aimed at
being used in component-based modular simulation environments such as TRNSYS or
HVACSIM+. The ground loop heat exchanger model is capable of accounting for short (1 hour or less)
time-step effects, while also accounting for very long-term (30 years+) borehole
interactions.
Much of this work was funded by the U.S. Department of Energy. Six-page
summaries of work done in 1998
and 1999
are available.
