项目摘要

In this research we aimed to build an integrated thermal and air quality design system that uses inverse transform methods for indoor (and outdoor) thermal and air quality analysis simulations based on CFD (Computer Fluid Dynamics). With this aim we developed procedures, and more specifically used inverse problem analysis to develop an automatic optimized environmental design system, seeking physical boundary conditions that best approximate design target values of indoor (and outdoor) environmental conditions and behavior.The following specific steps were undertaken ::1.Modeling of design behavior :We modeled the design behavior of designers by determining the hierarchical structure of design targets in the environmental design, determining the hierarchical structure of the design process, and building a feedback system into the design process.2.Using CFD to build an integrated indoor thermal and air quality analysis system :Using CFD coupled analysis of convection, radiation, and moi … More sture transportation in indoor locations of uneven temperature, velocity, radiation and humidity to quantitatively assess contributions to the indoor environment of each control factor.3.Development of an optimal assessment system :We developed a quantitative assessment procedure for optimized design of indoor environments. It exhibited multi-purpose decision-making logic for choosing the preferred solution to a multi-purpose optimization problem from a set of Pareto solutions.4.Development of procedures for optimized design :We introduced genetic algorithms (GA) to analyze inverse problems efficiently. In inverse analysis of CFD, CFD results are fed back into input changes and calculations repeated. Introducing GA into this process facilitates efficient inverse analysis. We also developed Stage 2 type optimized design procedures to reduce the calculation load in optimized inquiries that use GA. We also introduced dependability design and robust design procedures that take into account probability changes in design variables.5.Creation of a proto-type optimized design system.We applied the optimized design system developed in 1 to 4 above to indoor and outdoor thermal environment optimized design and investigated its effectiveness.6.Completion of the optimized design system.
