Volume 2, Issue 8, 18 August 2021, 100540 Phase change materials (PCMs) having a large latent heat during solid-liquid phase transition are promising for thermal energy storage applications. However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/ (m ⋅ K)) limits the power density and overall storage efficiency.
In comparison with sensible heat storage devices, phase change thermal storage devices have advantages such as high heat storage density, low heat dissipation loss, and good cyclic performance, which have great potential for solving the problem of temporal and spatial imbalances in the transfer and utilization of heat energy.
The transition was observed to vary from 153 to 182 kJ/kg. These properties are of prime importance in the design of a latent heat thermal energy storage system. ergy storage. The parametric study of phase change transition included transition time, tem- characteristics of the employed circular tube storage system. Dimaano and Escoto have
Phase change thermal storage and heat exchange technology have been widely used in solar thermal power generation, solar medium, and low-temperature thermal utilization.
However, there are also issues such as the small thermal conductivity of phase change materials (PCMs) and poor efficiency in heat storage and release, and in recent years, enhanced heat transfer in phase change thermal storage devices has become one of the research hotspots for optimizing thermal storage devices.
