冷却和除湿盘管的响应是空调设备系统分析的重要组成部分，因此，有必要获得一个真实描述其动态行为的模型。K.R.McCullagh（1）在题为“利用动态关系分析冷水冷却和除湿盘管”的论文中，建立了冷却和除湿换热器的数学模型。这是一项仅针对冷却和除湿盘管不同负载条件的稳态性能研究。在本文中，使用相同的方程以两种方式求出频率响应:（a）使用不同水和空气速度下进水温度的阶跃变化，然后通过一组矢量的图形分析或通过数值方法求出频率响应。（b） 在操作模拟中使用不同频率的正弦输入信号，并记录输出信号。 引文:美国密苏里州堪萨斯城ASHRAE学报第76卷第2部分

The response of the cooling and dehumidifying coil is an important part of the system analysis of an air conditioning plant, and it is, therefore, necessary to obtain a model which describes its dynamic behaviour realistically.K. R. McCullagh (1) in the paper entitled "An Analysis of Chill Water Cooling and Dehumidifying Coils Using Dynamic Relationships" has set up a mathematical model of the cooling and dehumidifying heat exchanger. This was an investigation of steady state performance only, for varying load conditions of cooling and dehumidifying coils.In this paper the same equations are used to find the frequency response in two ways:(a) Using a step change in inlet water temperature for different water and air velocities and then finding the frequency response by graphical analysis of a group of vectors, or by a numerical method.(b) Using sinusoidal input signals of varying frequencies in the operational analog and recording the output signals.
