    <p>Ali,</p>
    <p> The source code for the standard library components is in the
      .\TrnsysXX\SourceCode\Types directory and the source code for the
      TESS Library components is in the .\TrnsysXX\Tess
      Models\SourceCode directory. Source files are text so you can open
      them with Notepad. If you change them you'll need a way of
      recompiling them into a dll. They are not recompiled on the fly
      before each simulation.</p>
    <p> There are some air-based solar collector models in the TESS
      Solar library. You will also find some collector models in that
      library in which you can define a desired outlet temperature and
      have the model tell you what flow is required. I am not sure if
      any of the air-specific collector models have that feature so you
      may need to use one of the collector models that does not
      specifically have air as its working fluid and set it's working
      fluid specific heat to that of air.</p>
    <p>best,</p>
    <p> David</p>
