Hi Ricard, do you mean when water-cooled VRF is modeled, we need to leave Heating Performance Curve Outdoor Temperature

Not so sure how you have done your comparison between an air-cooled and water-cooled VRF system. I suspect the curves us

2016-08-03 11:05:24 -0500 asked a question ASHRAE 90.1-2007 App G PRM G3.1.2.4

As I have searched web and try to understand the 90.1 clause G3.1.2.4, the system needs to use night cycle and keep outdoor air flow rate to zero. I therefore just have a simple question, if above understanding is right, how re-circulation (no outdoor air) alone to meet the cooling/heating loads from zones during unoccupied hours? Do coils work as well during night cycle? Thank you very much in advance for any reply.
