Basic understanding of building simulation (to obtain the requisite loads), HVAC systems, and ground source heat pump systems is assumed.
Monthly heating and cooling loads on heat pumps; monthly peak heating and cooling loads on heat pumps; heat pump data; ground thermal properties; borehole configuration; maximum and minimum acceptable heat pump entering fluid temperatures (EFT).
Required size of ground heat exchanger corresponding to maximum and minimum acceptable heat pump EFT; required size of supplemental heat source/sink for HGSHP systems; month-end daily average EFT, monthly minimum and maximum heat pump EFT. Also provides input for simulation of ground heat exchangers in EnergyPlus.
Design of vertical, closed-loop ground heat exchangers.
