H-10 Development of the design tool of the Ground Source Heat Pump System and its application : Part-5 Installation effect prediction of the GSHP system with steel foundation piles as the ground heat exchangers for large scale buildings in cold region

Abstract

Two kind of large scale buildings planed installations of the GSHP system with steel foundation piles as the ground heat exchangers in cold region are predicted performance and installing effect by a design and performance prediction tool for the GSHP system. In the fast one, it was shown that the GSHP system with 70 steel foundation piles of 37m long can operate for heating and cooling demand of the building of floor area 2000m^2. Another performance prediction of the GSHP system with 51 steel foundation piles of approximately 4.7m long demonstrated the heating output of the GSHP system enough to cover the base heating demand of 50kW generated by ventilation of the building.
