摘要
针对低温实验设备的防潮隔汽设计,介绍了对防潮隔汽材料的性能要求,并用渗透阻分析的方法对隔热结构内部不出现凝水和冻结的要求进行了分析,得到了隔热结构不产生水聚集的条件和防潮隔汽层厚度的计算公式。
For the design of moisture-proof and vapour insulation of the cryogenic test equipments,the performance requirements of the materials were introduced. The condition that moisture doesn＇t condensate and freeze was analysed and the formula for calculating the thickness of the moisture-proof cross was also obtained.
