[0047] 1. Phase change energy storage materials
[0048] Refrigerant hydrate
[0049] Using a three-step method, the first step will be 0.2% nano-TiO 2 , 0.3% nano Cu is mixed to make nano powder. In the second step, 23.5% HCFC-14lb, 23.5% HFC-134, 47% water is made into cold storage medium base liquid, and then the above-prepared nano powder is combined with cold storage medium base liquid. The liquid is directly mixed to make the nano-powder cold storage medium base liquid; in the third step, 3% ethylene glycol, 1% Tween-81, 1% octylphenol polyoxyethylene ether non-ionic surfactant OP- 7 Mix to make a dispersant. Finally, after mixing the nano-powder cold storage medium base liquid with the dispersing agent, it is stirred by a motor or super-vibrated to form a suspended and stable refrigerant hydrate phase change energy storage material, distributed phase change storage The energy device is filled with the phase change energy storage material (4d).
