Abstract

The contribution ratio of indoor climate (CRI) based on CFD was developed to estimate the individual contribution of heat factors to any location inside a room. However most of the studies related to CRI involve forced convection airflow fields. Thus the purpose of this study is to make the CRI effective also in natural convection air flow fields. In this study, a new calculation method was proposed by means of setting a uniform heat sink. A CFD simulation coupled with convection and radiation has been performed in an atrium and the CRI of all heat sources are calculated by the new definition of CRI. Also an approximation method is proposed to discuss the sensitivity of each heat source.
