为动态太阳能集热器测试方法开发了数学传递函数模型和测试程序的数值解。一系列的实验和结果被提出来说明该方法。对各种试验条件下流体出口温度预测值与实测值之间的误差分析表明，传递函数法可以准确预测流体出口温度。对于不稳定测试条件，平均误差小于 1°C。最后，对传递函数方法进行了评估，以便为未来的设计提供可能的改进。
The numerical solutions of the mathematical transfer function model and test procedure were developed for dynamic solar collector test method. A series of experiments and results are presented to illustrate the method. Analysis of the errors between the predicted and measured fluid outlet temperatures for various test conditions show that the transfer function method can accurately predict the fluid outlet temperature. The average error is less than 1°C for unsteady test conditions. At last, the transfer function method is evaluated to provide possible improvements in the future designs.
