摘要: Abstract The boundary convective heat transfer of air-conditioned rooms has a large effect on the indoor thermal environment. To design comfortable environment, unknown wall fluxes must be determined. Current inverse models that determine required conditions use an iterative guess-and-correct procedure, which is quite time-consuming. This study proposes method based Tikhonov regularisation and least-squares optimisation using computational fluid dynamics (CFD) to in environments. can then solved by matrix operations with discrete target temperatures at distinct points. accelerate solving contribution ratio climate (CRI) applied describe cause–effect relation between resulted certain finds developed accurately efficiently fluxes. only prerequisites implement proposed are fixed flow field given points space.
