공동주택의 수요반응형 급탕환수 시스템 적용을 위한 성능 분석

Abstract

This paper aims to analyze the advantage of on-demand recirculation system implementation in domestic residential building.On-demand recirculation system is a structure of the domestic hot water (DHW) supply system, and it is possible to reducethe consumption of energy and water of DHW system by minizing waiting time. Condition for simulation is surveyed throughthe literatures, and simulation with the TRNSYS program is conducted to analyze the effect of the introduction. The resultshowed 0.7% reduction of hot water energy, and 4.5% reduction of wasted water, proving the system is beneficial when itimplemented into the domestic residential buildings.
