eQuest No cooling or heating load on VRF with DOAS

Bryan Papaj's avatar


I have a water-cooled VRF system with a DOAS. I modeled this as each individual zone getting its own individual PSZ and followed the eQuest modeling tutorial from Mitsubishi. The DOAS was modeled with a dummy zone and feeds each VRF zone with the OA-From DOAS. The problem that I am facing is that when I am simulating I have many unmet hours for the VRF zones and when I review the SS-A System Loads Summary Report I see that there is no cooling or heating energy. Has anyone experienced this before and if so how can I load the VRF system? Also, is there a way to see the individual zone heating or cooling contributions from the DOAS.

Thank you, Bryan

It might be worth double checking the performance curves that you used for the VRF system. If you copy them into you .INP file, sometimes they can overflow the line length and then get cut off when being read by eQUEST. What version of eQUEST are you using?
