Simulation of a Ground Source Heat Pump System for Simultaneous Heating and Cooling

Stephanie Loizide, Kathrin Menberg, Ruchi Choudhary

Abstract: This study comprises the simulation of the ground source heat pump (GSHP) system of a university building in the UK; this GSHP is non-standard, as the same heat pump unit provides space heating and cooling simultaneously. The overall cooling demand can be met by the simulated GSHP cooling circuit. However, the heating GSHP system in reality fails to pre-heat the return flow from the radiators, as the supply and return flow temperatures of the radiators are higher compared to the simulated scenarios. Sensitivity analysis results indicate that heating plate heat exchanger and boilers set point temperatures have the greatest impact on the system electricity consumption. System electricity consumption can be reduced by 5% by changing the set-point temperature parameters of the system.
