Kai,There are some cooling coil models in the TESS HVAC library that take combinations of coil effectiveness and bypass fraction. As such, they are not as much a "first principals" model as Type52 is but on the other hand, they can be used to model whatever liquid you want on the liquid side since they simply ask for the liquid specific heat as a parameter.

Hello, I try to simulate a building with a cooling coil. I found the standard Type 52, but this Type can just calculate the energy transfer with air and water as heat transfer medium. Does somebody can recommend me an Type with whom I can calculate a water glycol mixture as heat transfer medium. Thank you Kai
