摘　　要：在一台可视化蓄冷槽 (容积为 0 .1 6m3)的蓄冷实验系统上进行了冰和 HCFC-1 4 1 b水合物蓄冷实验研究 .结果表明 :HCFC-1 4 1 b水合物主要在盘管的间隙中生长 ,具有非贴壁生长现象 ;在实验条件下冰的蓄冷量为 HCFC-1 4 1 b水合物蓄冷量的 1 .5 9～ 2 .1 0倍 ,但 HCFC-1 4 1 b水合物蓄冷速率达 6666.7k J/h,是冰蓄冷速率的 1 .62倍 .表面活性剂 SDS对增加水合物蓄冷量的作用明显 ,比没有添加 SDS时水合物蓄冷量增加约 3 2 %。A 0.16m 3 in direct contact clathrate hydrate cool storage system is set up. HCFC 141b is selected for forming gas hydrate. The crystallization process is observed carefully, and the temperatures in different points and the capacity of cool storage charged or discharged are obtained. The characteristic of the temperatures is analyzed simply. During this entire course of solidification HCFC 141b gas hydrate crystal being developed between the cooling coils, no solid is formed on the cooling coil and the coil is mostly remained surrounded by the liquid. Under the conditions of experiments, the capacity of ice cool storage charged is 1.59～2.10 lar ger than that of HCFC 141b gas hydrate. By contraries, the rate of cold energy stored of gas hydrate is about 6 666.7 kJ/h, which is 1.62 times of that of ice cool storage. SDS increases the capacity of cool storage distinctly, and it also increases the rate of cold energy stored of gas hydrate.
