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.
Application of phase change energy storage in new energy: The phase change materials with appropriate phase change temperature should be selected according to the practical application. The heat storage capacity and heat transfer rate of phase change materials should be improved while the volume of phase change materials is controlled.
At present, the application of phase change energy storage technology in solar energy mainly includes solar hot water system , , solar photovoltaic power generation system , , PV/T system and solar thermal electric power generation . 3.1. Solar water heating system
In the daytime, when the solar radiation is sufficient, in addition to heating the heat load, the excess heat can be stored in the phase change heat storage device, and the heat can be released at night to meet the demand of the load.
According to the wind and solar complementary advantages, it can provide energy for loads all day and uninterrupted, which will have great development advantages in the future. Finally, the development trend of phase change energy storage technology in new energy field is pointed out. 2. Phase change materials
During the phase change process, the temperature of PCM remains stable, while the liquid phase rate will change continuously, which implies that phase change energy storage is a non-stationary process. Additionally, the heat storage/release of the phase change energy storage process proceeds in a very short time.
