Thermal Environment Analysis of a Classroom by CFD Simulation to Determine Optimal Temperature Sensor Position in Ceiling Type Air-Conditioning System

천정형 에어컨 온도센서의 최적 위치 결정을 위한 교실의 CFD 열환경 분석

Nowadays, the thermal environments of classrooms are usually adjusted by the ceiling type air-conditioning system with a temperature sensor installed on inlet of an air-conditioner. However, it is not clear that the conventional temperature sensor position is proper to satisfy both thermal comport and energy saving in summer especially. Therefore, this study is aimed at finding out the best position of the temperature sensor on the purpose of the comfort thermal environment and energy saving. The different 5 positions for the temperature sensor are supposed in this paper to analyze thermal environment by CFD. From the analysis through the CFD simulations, the best position of the temperature sensor satisfying for both comfort thermal environment and energy saving is obtained.
