The well known problem of evaluating the dynamic heat storage capacity of a 1-D slab is analysed and extended to case of general boundary conditions and general periodic excitation profiles of any form. A general relation to calculate the storage capacity is obtained in closed form for the harmonic case. Equations in time and frequency domain to calculate the storage capacity under periodic (non-harmonic ) heating are also obtained. Some particular cases are analysed and examples are given to show the applicability of the analysis.

Abstract
The well known problem of evaluating the dynamic heat storage capacity of a 1-D slab is analysed and extended to case of general boundary conditions and general periodic excitation profiles of any form. A general relation to calculate the storage capacity is obtained in closed form for the harmonic case. Equations in time and frequency domain to calculate the storage capacity under periodic (non-harmonic ) heating are also obtained. Some particular cases are analysed and examples are given to show the applicability of the analysis.File allegato/i alla scheda:
