heal.abstract	Based on a finite-difference solution of the transient, periodic wall heat conduction differential equation and on the superposition principle, a correlation is developed, which expresses the maximum periodic indoor heat flow in terms of two wall-dependent coefficients m and r, and two corresponding climatic parameters ΔTmax and ΔTr. Tables with the values of the wall coefficients and the climatic parameters are available for 15 typical wall constructions and various cities around the world. Based on the present method, it is easy to develop more extensive tables. The above correlation is directly applicable when the maximum outdoor air temperature and the daily range for the location considered are known. When the temperature information is available in the form of the mean temperature and the amplitudes of a cosine and a sine variation, another correlation is suggested. The correlations developed are useful in building heat transfer applications and especially in the design of air-conditioning installations, for estimating peak loads and sizing the related equipment. © 1994.	en
