A Comprehensive Study on Ground Source Heat Pump Applicability

摘要

Ground coupled heat pump (GCHP) technology has the energy saving potential, but closely related to the building ambient conditions. This paper studied the effect of climatic condition on the ground heat flow balance. A 4603 m~2 floor area building was used as the base building and EnergyPlus software was used as the simulation platform. 73 cities from 5 climate zones in the great China region were selected to study the effect of climatic condition diversity on the ground heat balance. Based on the ground heat flow ratios 73 cities were grouped into 5 categories with different GCHP applicability. This paper provided a strategic assessment method on GCHP applicability study.
