摘要
提出了制冷空调行业常用的热交换器的微元模拟方法 ,并在此基础上构造了加热、冷却与冷却减湿工况下热交换器微元及其组合而成的热交换器的热力学模型和流体力学模型。介绍了利用上述模型进行动态模拟和求解的方法 ,经与传统计算方法和实测结果对照 ,显示了模型的合理性。
This paper presents the element simulation method for the heat exchanger,which is widely used in HVAC and cooling systems.The thermal and.aerodynamic models for the elements and the heat exchanger,which is combined by the elements in heating,cooling and dehumidifying conditions, are developed.The dynamic modeling and solution methods are also presented by using the models.The results were compared with real measuring results and those obtained using critical methods,and good agreement is attained.
