Q: How do you model using glycol in a chilled water loop?


There are two effects of using a glycol mixture in a chilled water loop:

  • One is to be able to lower the chilled water (that is, liquid) temperature -- that one is easy, since MM will set it to whatever you tell it, regardless of physics.

  • The other is a change (decrease?) of metal-liquid heat transfer coefficient inside the coils. This, indeed, we can model only by a change in COP.
