This paper proposes new techniques of identifing thermal systems, in which heat transfer from the atmosphere is isolated, and it is verified that the techniques can produce accurate results. The first technique is to obtain a curve fit for the measured temperature history with random error, by using the equation of linear heat flow in a solid bounded by a pair of parallel planes. The second technique is to use a three-columns band matrix for heat conductivity and heat capacity matrices of thermal systems. The third technique is to reduce unknown parameters of heat conductivity and heat capacity matrices by using the thermal characteristic of an isolated structure. The validity of the new techniques is shown by numerical simulation. It is demonstrated in its application that the temperature of a thermal system under varied forced heat flux can be accurately simulated by using the identification under constant forced heat flux.
