Description

technical field

[0001] The invention relates to a phase change energy storage material composition, which has a phase change temperature of 23-25°C, an undercooling degree of less than 3°C, and the composition has a relatively high phase change latent heat value, which can reach 180kJ / kg. It has excellent temperature regulation function and extremely high phase transition stability. It has been tested more than 3000 times in cold and hot cycle tests. The phase change energy storage material composition obtained according to the present invention can be used for solar heat storage, waste heat recovery, indoor temperature regulation and the like. Background technique

[0002] In the process of energy conversion and utilization, there are often contradictions between supply and demand that cannot be effectively matched in time and space, such as peak-to-valley differences in power loads caused by electricity consumption, intermittent supply of solar energy, wind energy, and oce...
