Energy Performance Analysis Program with Heating methods of Automatic Thermostatic Valves in Floor Radiant Heating System

바닥난방용 자동온도조절기의 난방방식에 따른 에너지성능 해석용 프로그램에 관한 연구

In this study, the energy characteristic of automatic thermostatic valves according to each heating method in floor radiant heating system were researched by computer simulation. For the analysis of unsteady heat transfer phenomena in household, the method of using electrical equivalent R-C circuit is applied, and radiation heat transfer between panel, ceiling and walls in household is calculated by enclosure analysis method. The parametric study on heating method, valve's control method, outdoor air condition, supply heating water temperature, supply flow rate are performed to compare energy characteristic, respectively.
