Does it let you pick DX for the multizone AHU type?

Hi John

If by packaged Cooing you mean Air Cooled DX then, how about trying:

  *   Dual Duct system w. CHW
  *   “Chiller” =  Air cooled with appropriate compressor type (recip or scroll) and count
  *   Pump power = 0
  *   CHW supply temperature = ~ DX evaporator T

Good luck

A friend of mine asked me about such a system. I looked it up, and lo and behold, eQuest doesn't this as a system.

Is there any equivalent system that can dynamically mimic this?

Thanks,
