Multiple equipment to the same zone

edit

Hello guys!

I need to simulate 2 zone that have 6 self contained refrigerating both zones at the same time. This 2 zones are cooling trhough the floor plenum and have the same return. Three self contained there are different configuration (curves). 1- Is it possible to add more than 1 air loop per zone? I tried, and it didn't work. 2 - I can create and connect this 6 air loop in parallel and apply in both zones?

Anyone know other way to solve this problem?

Thanks!
