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.
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.
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
By taking advantage of latent heat, large amounts of energy can be stored in a relatively small change in actual temperature, and accessed by manipulating the phase change of a material. Perhaps the most common form of phase change heat storage on the market is the sodium-acetate handwarmer.
Box-type phase change energy storage thermal reservoir phase change materials have high energy storage density; the amount of heat stored in the same volume can be 5–15 times that of water, and the volume can also be 3–10 times smaller than that of ordinary water in the same thermal energy storage case .
The phase change energy storage – wind and solar complementary system is a renewable energy combined power supply and heating system, which is composed of three parts: solar energy collection, photovoltaic and wind power. Among them, the solar heat collecting system converts light energy into heat energy through the solar collector.
