Full Description

Points out that the wall and roof transfer function coefficients b(n subscript) and d(n subscript) listed in the 1993 ASHRAE Fundamentals Handbook, have up to now been derived using Laplace and Z-transform methods. Shows that they can be readily evaluated using straightforward time-domain solutions of the Fourier continuity equation. These include the response of a wall to a ramp increase in temperature and its transient response.
