摘 要: 为了深入了解水合物的生长动力学机制,通过对混合致冷剂HCFC141b/HFC152a水合物晶体生成及分解过程的形态进行观测,从动力学和形态学方面验证了混合致冷剂水合物的性能互补特点。结果表明,混合致冷剂水合物与低压致冷剂HCFC141b水合物相比,其引导时间更短,生成速度更快。混合致冷剂HCFC141b/HFC152a水合物可在10℃融化,克服了高压致冷剂HFC152a水合物相变温度高的缺点,证明了混合致冷剂水合物较单一致冷剂水合物更适合作为蓄冷空调的储冷介质。 The morphology of mixed refrigerant HCFC141b/HFC152a hydrates formation and decomposition process is observed. Reciprocal properties of mixed refrigerant hydrates are testified from kinetics and morphology. The formation and decomposition properties of mixed refrigerant hydrates, in comparison with low pressure refrigerant HCFC141b hydrate, have been improved intensively. Induction time is shortened, and formation rate is accelerated. In comparison with high pressure refrigerant HFC152a hydrate, mixed refrigerant hydrates overcome the disadvantage of high equilibrium temperature, which show that the mixed refrigerant hydrates have better properties than single refrigerant hydrate for cool storage of air conditioning.
