| Abstract | Two methods of calculating the periodic heat flow through solid walls of roofs are described. The matrix method gives the accurate value of heat flow through a solid wall whether homogeneous or multilayer. One of the advantages of this method is the ease with which different surface heat transfer coefficients can be accounted for. A much simpler vector diagram method is presented for calculating the complex thermal impedance of a wall or roof. The errors which occur with this method are chiefly due to representing a continuous wall by a lumped resistance-capacitance network. The lumping error for a "T" network representation of a homogeneous wall is evaluated analytically: the same method can be applied to more complex circuits. |
