It is found that the heat release characteristics are greatly affected by the flow direction of the heat transfer medium since natural and forced convections coexist in the heat storage vessel. It is clarified that the thermal efficiency of the latent heat storage system is obtained by an upward flow along the vertical PCM for heat release process The effect of the inlet velocity and the inlet temperature of heat transfer medium and the dimensions of the phase change material on transient heat release characteristics of the latent heat storage system are also revealed in the present study. No potential conflict of interest relevant to this article was reported.
