How to add FCUs and FAHUs together?

asked 2017-01-24 02:23:17 -0500

updated 2017-05-06 08:29:02 -0500

I am using detailed HVAC and have assigned 32 Fan Coil Units (PTAC) to 32 zones of the building I am simulating. Now all the zones are also connected to 3 Fresh Air Handling Units.

Problem is when I assign the FCUs and select the zones in zone groups then how do I assign FAHUs to all zones, as they disappear from zone group options because they already are assigned the FCUs?

First, please see the post:

Then go to the zone group and select any thermal zone. Select “Add Direct air” option and put it in your thermal zone.

After that go to “Add Loop” tab and select “Add Generic Air Loop”.

The last step is to connect the AHU to the fresh air intake and to the exhaust. You can put a heating and cooling coil, based on your design.
