Research on the Contribution Ratio of Indoor Climate in an Atrium Dominated by a Strong Natural Convection

Abstract

    Indoor thermal environment is composed of various heat factors both from outdoors and indoors. The contribution ratio of indoor climate (CRI) based on CFD is developed to estimate the individual contribution of these factors to any location inside a room. Since most of the studies related to CRI are considered in forced convection air flow field, the purpose of this paper is to analyze the heat transfer by convection and radiation respectively by using CRI in an atrium dominated by a strong natural convection.
