这段代码是一个简单的太阳能集热器模型,用于TRNSYS类型155的模拟。它通过接收和传递一些参数和数据来与TRNSYS交互。
以下是与TRNSYS交互的数据变量:
- trnTime:模拟时间
- trnInfo:TRNSYS信息数组
- trnInputs:TRNSYS输入
- trnStartTime:TRNSYS模拟开始时间
- trnStopTime:TRNSYS模拟停止时间
- trnTimeStep:TRNSYS模拟时间步长
- mFileErrorCode:该m文件的错误代码。TRNSYS将其设置为1,m文件应将其设置为0以指示调用成功。任何非零值都将停止模拟。
- trnOutputs:TRNSYS输出
此外,代码中还有一些注释提供了一些说明和注意事项。例如,可以使用trnInfo(7)、trnInfo(8)和trnInfo(13)的值来识别调用的情况,也可以通过trnInfo(3)和trnInfo(6)来确定输入和输出的数量。
请注意,如果使用多个类型155的单元,则从/到TRNSYS传递的变量将根据所有单元的最大需求进行调整大小。因此,您应该仅使用当前m文件真正使用的数组部分。此外,请注意所有m文件在Matlab中共享同一工作空间(它们是“脚本”,而不是“函数”),因此变量如trnInfo、trnTime等在每次调用时都会被覆盖。
总体而言,这段代码实现了一个简单的太阳能集热器模型,应在每次TRNSYS调用时进行迭代。
