Abstract

Improved procedures for performance prediction of vertical U-tube ground heat exchangers (GHEs) in Ground-Coupled Heat Pump (GCHP) systems are proposed using cylindrical source functions. Appropriate length of timesteps to simulate the performance of GHEs under conditions of variable heat loads is also studied for the practical application of the procedures.
