摘要
CFCs的禁用 ,迫使电站制冷式氢气去湿系统的原制冷剂R12必须替换。通过技术经济综合分析比较 ,选用R134a作为替代工质 ,并分析了采用R134a后系统的主要部件及关键参数应做的改进。利用现有电力、制冷行业中的强化传热技术改进原系统的换热设备。在此基础上提出了新系统研究与开发的具体内容 。
Since the use of CFCS is prohibited refrigerant R12 used in the Refrigerating hydrogen mositure removal system for power station must be replaced. By R134a, and main components of the system must be improved. Modern transfer heat technology used in electrinic power and refrigeration industries are used to improve the heat tranfer equipment.
