【Abstract】 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.更多还原
