IES-VE User Forum

Hi,

I am modelling the HVAC Schematic and there an error message indicating that all the closed loop of the HVAC air system must contain at least one room. When I have all room assign to all the schematic. How shall i resolve this problem? Is there any option in IES to indicate the problem in the schematic such as like a model report created to view the mistake.

Hi,

Encountered the same issue today. I guess check your multiplex rooms for the adiabatic spaces and re-assign the ones which have been changed to adiabatic rooms (no clue why it happened). It worked for me!

yes that solution makes sense.

Obviously first of all do the basic check and ensure that flows are set in the correct directions and you haven't ended up with any loops not including a room (consider all paths).

Failing that then check your Multiplex assignments, you can do this via Multiplex to ensure you have a room assigned to every layer or else switch to local edit mode and flick through the layers to check there is a room assigned ot each layer.
