Abstract
The subject of this paper is the heat source system with the Ground Source Heat Pump(GSHP) system in the PHC foundation piles. The thermal storage characteristics of the ground may be used to improve the GSHP system performance in this hospital by alternating the storing and restoring cycle on day-night basis in the summer season. The analysis during the commissioning shows the effectiveness of the GSHP system concept and improved system performance as a result of changing the operational condition.
