주거용 건물을 위한 냉난방 및 급탕 통합 히트펌프 시스템의 에너지 절감 가능성 분석

초록

The present study aims to evaluate energy saving potential of heat pump system functioning as cooling, heating and hot water supply applicable for residential buildings. To analyze the advantage of integrating heating and cooling, existing mono function air-source heat pump and radiant floor heating system were set to the reference case. The model building was established in TRNSYS 18, and integrated energy simulation in annual was conducted with all system model equations in EES program. The results show that proposed heat pump system reduced 11-12.5% energy consumption in simulation cases, compared to the reference system.
