Abstract

Ground source heat pump for cooling-dominated commercial buildings may utilize supplemental cooling towers to reduce system first cost and to improve system performance. The use of hybrid ground source heat pump (HGSP) can reduce the size of the ground-loop heat exchanger. Degradation of the heat pump performance due to the excess heat in the ground can be avoided by offsetting the annual load imbalance in the bore field. The operating performance and energy consumption of GSHP are analyzed in different operating and control strategies based on experimental results. A comparative study is presented that investigates the advantages and disadvantages of various system operating and control strategies.
