Z-TRANSFER FUNCTION COEFFICIENTS FOR SIMULATION OF THREE-DIMENSIONAL HEAT TRANSFER IN BUILDING WALLS

摘要

Numerical method to derive the conduction z-transfer function coefficients from the response factors, for three-dimensional wall assemblies, is presented. Response factors and the so-called structure factors, are computed using the computer code to simulate three-dimensional heat conduction. The z-transfer function coefficients are then derived from the set of linear equations, relationships with the response factors, which is to be solved using the minimum error procedure. Test simulations show perfect compatibility of the heat flux calculated using three-dimensional response factors and three-dimensional z-transfer function coefficients.
