摘　　要：在一台可视化蓄冷槽容积达0.16m3的蓄冷实验系统上进行了HCFC-141b水合物蓄冷实验研究。结果表明促晶扰动在水合物生成中至关重要,即使在较高温度,只要连续促晶水合物也能生成;冷媒流量越大,冷媒温度越低,水合物越容易生成,蓄冷量也越大;喷淋作用和反应历史的作用对水合物结晶温度和蓄冷量影响不大。A visual system with the capacity of 0.16m3 has been built up to investigate the cool storage with the HCFC-141b hydrate as the cool storage medium. The experimental results indicate that agitation has significant effect on the formation of gas hydrate. Even with the low supper-cooling degree, the hydrate can be formed with continuous agitation. The cool storage capacity increases and the formation is easier with the increasing flow or decreasing medium temperature. While the spraying and the history of gas hydrate has little effect on the formation temperature and cool storage capacity.
