Abstract

For the dynamic heat transfer characteristics of building external walls in solar-enriched areas under the dual thermal disturbances between low temperature and intense solar radiance, it is necessary to efficiently optimize the thermal insulation design in winter. Taking Lhasa as an example, this study uses a dynamic heat transfer numerical calculation model to analyze the influence of the change of thermal resistance and thermal inertia index on the thermal response characteristics of composite external walls. After that, the functional relationship expressions among these three factors, namely Poly2D, LogNormal2D, and Plane, were constructed, and the variations patterns of the interior surface temperature of the south and north facing external walls were revealed under the combined influence of thermal resistance and thermal inertia index. On this basis, the matching relationship suggestions between the minimum thermal resistance and thermal inertia index of external walls were proposed. The findings obtained in this study can provide rapid and convenient parameter optimization guidance for the optimized design of the thermal performance of building envelopes in solar-enriched areas.
