Examinations of steady status and analysis of dynamic experiments have been conducted on Band-Tube evaporator and Parallel-Flow condenser using R134a refrigerant. The steady examination show that the model error was under the allowable error, The inlet mass and enthalpy disturb experiments indicate that the subsection model ,be good at reflecting the change of parameters of the heat exchanger, accord with the basic principle of thermodynamics theory and the actual work status.

在进行仿真试验时，以使用R134a作制冷剂的管带式蒸发器和平行流式冷凝器为对象，完成了稳态仿真计算、试验和动态仿真分析，稳态计算结果和试验数据对比表明，其误差在允许范围内；进口质量和焓值的扰动试验结果表明：本文所建的区段式换热器仿真模型，能很好的反映换热器性能参数的动态变化，与系统热动力学理论和冷凝器、蒸发器的实际工作过程基本一致。
