DEVELOPMENT OF THE COUPLED SIMULATION OF CFD AND ENERGY SIMULATION AND APPLICATION EXAMPLES: Fundamental research on the coupled simulation of CFD and energy simulation (Part 2)

We proposed how to predict the thermal environment easily and quantitatively according to the change in the heat load by CRI. The indexes called CRI (Contribution Ratio of Indoor climate) were developed so that how each heat source or sink in a room contributes to form the local air temperature can be easily looked into. And, we developed energy simulation considering spatial distribution, by coupling the thermal predict equation with CRI and Energy simulation, such as thermal network calculating program. In this paper, we show case study of this mathematical evaluation method in comparison with two HVAC systems in a classroom, radiation floor cooling with underfloor air-conditioning system, and conventional one, and confirm the effectiveness of this new approach.
