Non-equilibrium Thermal Insulation Analysis of Self-insulation Wall

Abstract

In this paper, a mathematical model for calculating the cooling load of self insulation wall in unsteady heat transfer process is established. According to the reaction coefficient method based on Laplace transform and inverse transform, a software for calculating and analyzing the cooling load of self insulation wall is developed. The software can not only analyze the dependence of thermal parameters including thermal conductivity on the cooling load of external wall, but also analyze and calculate the self insulation wall. The non-equilibrium thermal insulation thickness of thermal insulation wall in different directions will provide practical calculation basis and data support for dynamic thermal insulation design of self insulation wall in energy-saving buildings.
