Proposal of coupling CFD with energy simulation by CR1

Abstract

This study aims at the development of the coupled simulation of building energy simulation and computational fluid dynamics (CF'D). We proposed the indexes called CR1 (Contribution Ratio of Indoor climate), which represents how each heat source (sink) in a room contributes to form the local air temperature in a specific flow field, and how to predict room air temperature at arbitrary points by CR1. In this paper, we propose a new approach to integrate the information of the spatial distribution into the energy simulation program by expressing the air temperature as a function of CR1 and the potential of each heat source. This integration method enables the energy simulation to consider the spatial distribution.
