Hello All,
I am wondering if if it possible to model a space with where return air is sent from one node to an air-conditioning system and is then supplied to a different node. This space has a stack of several air nodes. The supply would be at the top, and the return at the bottom.
As far as I can tell, type 56 supplies and returns ventilation air to the same node. Is there a way to get around this?
My current thought it to use airnode coupling between each node going down the stack and then adding a bogus node which is set to a temperature and humidity equivalent to the air-conditioners output conditions. This bogus node would then be coupled to the top node. The air-conditioner would use the air temperature and relative humidity of the bottom node as its input air conditions to determine the output conditions.
Thanks for your help,
Chris, MASc
