Technical note: On the transient thermal behaviour of structural Walls-the combined effect of time varying Solar radiation and ambient temperature

摘要

The aim of the present work is to investigate the transient conduction heat transfer in struc- tural walls. The developed finite difference numerical simulation code, which is suitable to run in conventional microcomputers, has the flexibility to incorporate a wide range of boundary and initial conditions and time-dependent forcing functions for the investigation of the transient heat transfer in walls of any design. The analysis was employed for the prediction of the dynamic thermal behaviour of two wall designs under the effect of a step temperature change and a combined time varying ambient temperature and solar radiation corresponding to typical local weather conditions.
