This report describs a method of calculating temperature and heat flow through a combined wall when the former two are in a periodically steady state. In this method, we use impedance matrix which is defined as a system function of the temperature and heat flow on one side of the wall to those of the other side. Temperature and heat flow over every section of a combined wall, as well as each element of the impedance matrix, are represented by complex vectors instead of sine waves. Therefore, in preparing a table of elements, both the absoluts and the arguments, we can easily caluculate temperature and heat flow through a combined wall when they are in a periodically steady state.
