OpenStudio "AirLoop Unitary System" object
Hi.
I was looking for how to build the water sourced heat pump at AHU, my case is DOAS.
With some research, decided to use "AirLoop Unitary System" which can be connected to water sourced plant loop.
Few questions pop up for this setup.
Q1. That unitary system already having its own fan which is mostly of CAV, so decided to turn off that fan within unitary system and place Variable flow fan after that unitary system.
I ran it and when it is checking the hourly data, it seems working on my end.
Q2. Not applying at AHU, but if we place "AirLoop Unitary System" at thermal zone level (within thermal zone tab in OpenStudio), it is checked that this equipment is not delivering ventilation air at all. Is there best practice I can have unitary system with variable fan at thermal zone equipment level?
Thank you
Q2: I tried to recreate your problem, but encountered another one. This will have to be resolved before the system will work at the AirLoop or zone
