North American monitoring of a hotel with room size GSHPS (ground-source heat pump system).

Author(s) : HENDERSON H. I., CARLSON S. W., WALBURGER A. C.

Summary

The 149-room lake front hotel has a ground loop that is partially incorporated into the building's structural pilings and a heat pump water heating system that is integrated into the ground loop of the space conditioning system. Loop temperatures are ranging between 4 and 27 °C across the year. The integration of the water heating heat pumps into the system reduced the summer heat rejection loads by more than 15%. Variable speed loop pumping dramatically reduced system energy use by 92% compared to a conventional constant speed pumping system. This system demonstrates the performance benefits of geothermal heat pump systems.
