摘　　要：选用有机复合相变材料和吐温80作为添加剂,利用均质乳化机制备了HCFC-141b+吐温80+有机相变材料+水乳液体系。利用混合量热法测量了添加剂对HCFC-141b水合物蓄冷密度的影响。与纯水体系相比有机相变材料能够显著提高HCFC-141b水合物的蓄冷量,缩短水合物生成的诱导时间。有机相变材料与吐温80协同作用水合物蓄冷密度最大,平均蓄冷密度达到268.1 k J/kg,较仅含相变材料水合体系的蓄冷密度提高了19.5%。Emulsion of HCFC-141b is prepared using high-speed stirring,where organic phase change materials and T80 are used as additives.The effect of additives on the HCFC-141b hydrate storage is tested using mixed calorimetry method.The experimental results show that the organic phase change material can significantly im鄄prove the capacity of cool storage of HCFC-141b hydrate compared with the pure water system,and decrease the induction time of hydrate formation.HCFC-141b hydrate has the largest capacity of cool storage with the addi鄄tion of organic phase change material and T80,and the average cool storage density is about 268.1 kJ/kg.The cool storage density increased by 19.5%compared with the hydrate system only containing the organic phase change material.
