Description

Unsteady analysis of the thermal environment of buildings with offices and colonnade space is difficult with energy simulation(ES) that represents space with one mass point and CFD has been mainly used. Even in ES it is possible to divide the space into zones, but because it is not a mesh division in detail, it will cause excessive heat loss, and to predict the heat transport due to the influence of a strong air current such as air conditioners, There is a problem on the above. To solve these problems, we propose a method to calculate the ratio of heat contribution to zones pre -divided by CFD and distribute the total thermal load calculated by ES. In this research, we propose a coupling method of ES and CFD which enables unsteady analysis of thermal environment in large space and verify its accuracyation results.
