Paraffin phase change energy storage device

Are phase change materials suitable for thermal energy storage?

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.

What are the applications of phase change heat storage technology?

Then, the application of phase change heat storage technology in different fields is discussed, including building energy saving, thermal management of electronic equipment, solar energy system and energy storage system.

How can a phase change heat storage device improve thermal conductivity?

Or package the phase change materials in different shapes and sizes; Mixing of graphite or nanoparticles helps to enhance the low thermal conductivity of phase change materials. On the other hand, the heat storage performance is improved through optimizing the phase change heat storage device.

Can paraffin encapsulation improve heating performance in air source heat pump?

Paraffin was encapsulated in the floor. The results show that increasing the thermal conductivity of PCMs can improve the heating performance of the system. Composite PCMs were added in air source heat pump, would has high energy utilization rate and reduce indoor temperature in defrosting mode.

Why are graphite foam and composite PCMS used in thermal energy storage?

From the results shown that due to the high thermal conductivity of the foam composite PCMs, the heating rate of the heat source surface was reduced, and the influence of gravity on the heat transfer was reduced, too. Andrew et al. simulated the thermal energy storage system (TES), which consisted with graphite foam and composite PCMs.
