벽패널 복사난방시스템의 방열특성에 관한 시뮬레이션 해석 연구

Recently the radiant panel heating and cooling system has been regarded as an alternative of low temperature heating and high temperature cooling by applying the renewable energy sources to the heating and cooling of buildings. Especially this system can be used as HVAC system alternatives in super high-rise buildings for energy saving and thermal comfort. Also it can be possible to reduce the plenum space because the minimum ventilation air will be supplied into the space. This study aimed at evaluating the basic characteristics of thermal output in radiant wall panel heating system. For this purpose, the thermal output of several radiant wall panel types were analysed by 3D dynamic heat transfer simulation. According to the supply water temperature, composition of panel layers and panel dimension, the thermal output characteristics such as surface temperature distribution, temperature difference between supply and return water were analyzed. The results show that we should improve the heat storage performance of wall panel for better distribution of surface temperature and thermal comfort.
