Heat Imbalance Analysis of a Hybrid Ground-Source Heat Pump System

Abstract:

Operating data in the last two years of a hybrid ground-source heat pump system (HGSHPS) were analyzed, and were contrasted to TRNSYS simulation results. Heat extraction from the borehole heat exchanger (BHE) of ground-source heat pump system (GSHPS) was too much larger than the heat injection, but heat extraction from the borehole thermal energy storage (BTES) of solar assisted GSHPS (SAGSHPS) was too less than the heat storage, in 2012. Serious problem of heat imbalance of BHE occurred, and the GSHPS almost could not work in the late heating season of 2012. An adjusted operating strategy was utilized in 2013. The ground temperature imbalance for GSHPS and heat excess for SAGSHPS were resolved. It is important to monitor the operation of HGSHPS to resolve the heat imbalance problem.
