Re: [EnergyPlus_Support] Connectiong two AirLoops to the same zone

In my case, I cannot substitute one of my airloops as a ZoneEquipment unfortunately. They are both air handlers.

The cross mixing idea is great, I never thought about that. But that would make me split all my zones into two which I think is a little difficult as I have a lot of zones. Maybe a good option if I had known this before zoning my building.

The DDAutosize.idf shows how we can split one airloop into multiple braches. On a rough glance, I think this should take care of the situation. Karen, I was just reading the post where you had suggested this approach to someone last month and how it worked for im/her.

Thanks for your valuable suggestions.

If you can't find appropriate zone equipment to substitute for one of your airloops, you can also try to put all of your airloop equipment onto one airloop with two outlets. Airloops are the only type of loop which are allowed to have more than one outlet node. Some example files to look at are the dual duct examples.

The solution is to use 1 air loop and 1 zone equipment.

I have also heard that you can trick the simulation by splitting each zone, serving each split zone with a separate air loop, and then using cross-mixing objects with high flow rates to mix the split zones. I have not tried this, but it sounds interesting.

Hello Robin,

Do you have a solution for this issue?

Hope to hear from you.

Hello,

I have txo separated AirLoop, one for the mechanichal ventilation, another for the Cooling. My problem is that I want to connect this Loops to one single zone, but there is only one Zone Return Air Node Name. And in fact, if i use this Return Air Node as the Zone Eqipment Outlet Node for both AirLoops, I have a severe error.

I tried using the exhaust node but I can't manage to connect it to the Airloop.

Thanks in advance.
