홈페이지논문 초록 (Abstract)
Geothermal heat pump system has been spotlighted as an efficient building energy system, because it has great potentials for redu cing energy in building air conditioning and reducing CO2 emissions. However, higher initial cost is a barrierto the promotion of i ts use. Energy-pile and energy-slab are known as low cost ground heat exchangers comparing withconventional ground heat exchangers , because they utilize building structures as ground heat exchangers. T his paper presents the daily cooling performance of a geothermal heat p ump system with energy-pile and energy-slab. The energy-piles and the en ergy-slabs are connected to heat pump units in parallel. The cooling cap acity of the system was nearly constant due to the stabilityof the gr ound heat exchangers. The stability of the energy-pile was a little hig her than that of the energy-stab as a heat sink.
