热交换器排放温度控制系统动力学研究的一个重要部分是单独研究热交换器的动力学。本研究通过分析和实验，考虑了管板翅式、蛇形、商用、水-空气换热器的动态特性。特别令人感兴趣的行为是排放空气温度对热水流量变化的动态响应。这与控制系统的常见配置相兼容，即使用由控制器驱动的流量调节水阀，以及热水盘管下游管道中的温度传感器来控制空气排放温度。 为了设计或选择整个系统的控制部件，需要一个准确但简单的热交换器动态模型。

An important part of the investigation of the dynamics of a heat exchanger discharge temperature control system is the investigation of the dynamics of the heat exchanger alone. This study considers, through analysis and experiment, the dynamic behavior of a tube and plate-fin, serpentine, commercial, water-to-air heat exchanger. The behavior of particular interest is the dynamic response of the discharge air temperature to changes in the hot water flow rate. This is compatible with the common configuration of the control system whereby a flow modulating water valve driven by a controller with a temperature sensor in the duct downstream of the hot water coil is used to control the air discharge temperature.To design or select the control components of the entire system, an accurate but simple dynamic model of the heat exchanger is desired.
