The required length of vertical ground heat exchangers (GHX) used in ground-coupled heat pump (GCHP) systems is determined to make the outlet temperature from the GHX remains within certain limits at peak ground load conditions. These conditions may not necessarily occur after 10 or 20 years of operation and often occur during the first year of operation. The primary objective of this paper is to develop a general methodology, using the framework of the ASHRAE bore field sizing method, for the calculation of the total required bore field length on a monthly basis during the first year of operation.
