<p>Hello All,</p>
<p><br>
</p>
<p>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.</p>
<p>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?</p>
<p><br>
</p>
<p>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.</p>

<p>Thanks for your help,</p>
