摘要
由于制冷空调工程中典型的网状自然对流换热元件——钢丝管冷凝器几何结构的复杂性，其辐射换热尚没有准确、简便的计算方法，本文作者通过实验——真空辐射法确定了钢丝管式冷凝器的系统黑度，其试验范围覆盖了一般制冷空调工程应用范围，可供工程设计实践中参考。
The wire-on-tube condenser is widely used in refrigerating and air-condtioning engineering.Because of the complex structure of the wire-on-tube condenser,the radiant heat transfer can not be determined in a simple and accurate way.In this paper,the system emissivity of the wire-on-tube is determined with the help of vacuum-radiation method.The experiment covers a wide range of refrigerating and air-conditioning engineering,which is helpful for the application or design.
