| titleOfInvention | Composite water-soluble hydrate phase change cold storage agent and preparation method thereof |
| abstract | The invention relates to a composite water-soluble hydrate phase change coolant and a preparation method thereof, wherein the coolant is prepared by mixing the following components in percentage by mass: 21% of tetrabutylammonium fluoride, 14% of tetrahydrofuran, 0.1% -0.5% of surfactant and water. The surfactant is sodium dodecyl sulfate or sodium dodecyl benzene sulfonate. The surfactant provides crystal nuclei, so that the hydrate can be crystallized and quickly crystallized near the crystal nuclei, the energy required by crystallization is reduced, the induction time of hydrate crystallization is shortened, and the supercooling degree is reduced. The phase change temperature of the phase change coolant is 279.8K-280.8K, and the supercooling degree is 3.3K-7.8K; the latent heat of phase change was about 213.3 kJ/kg. The phase change cold storage agent has the advantages of low supercooling degree, no phase separation phenomenon, long service life and simple preparation process, and is suitable for the field of cold storage of building central air conditioners. |
