Abstract
In off-line heat transport systems, erythritol is occasionally used as heat storage materials.Then, our purpose is to simulate numerically heat response of heat storage tank using erythritol. In this paper, one-dimensional unsteady heat conduction experiment for erythritol was conducted. As a result, in melting process, simulation results are in good agreement with experimental data. However, in unsteady freezing process, they are not in good agreement.
