Zone Equipment for Refrigeration System

edit

Hi all,

I am trying to model a walk-in freezer (including three thermal zones) in Open Studio 2.8.0, and I set up a refrigeration system which works with NH3. My problem is that in the thermal zone tab, I cannot find any related zone equipment to select. So far, I know that in energy plus it should be under RefrigerationChillerSet. However, there is no such measure in my library in Open Studio. Did anyone had this problem before?

Thanks
