Revision history [back]

I repaired your model by doing two things. First I removed three dangling zone exhaust nodes by manually editing the osm file. Second, I removed then re-added the terminals.

The repaired file is here.

I cannot say exactly why these dangling exhaust nodes ended up in your model. The API is supposed to prevent this kind of thing, but there have been past reports of it happening, and not necessarily related to the four pipe induction terminal, but always related to one of the terminal types that have induced air from the zone exhaust. I can say that after repairing your model I am able to remove the terminals cleanly, and add them back cleanly without issue in 1.7.0.

I sorted out the node connection issue related to your terminals in the above linked file, but I found other issues in your plant systems. Some of these may have been intentional on your part, but when I run the model I am seeing run away plant temperature. On your hot water plant I found a chiller which seems a little odd - I replaced the chiller with a boiler. The chiller I removed was connected to a condenser system - I removed this condenser system because it was left with no demand components. The chilled water condenser system had a ground hx on it - I replaced the ground heat exchanger with a cooling tower. The fully modified (and running) model is here.

I will keep an eye on this exhaust node issue. Please report back here if you have any more issues with that.

* Update on 10/28/2016 **

Here is an OpenStudio script I used to repair the model from Jesse Perreault. It might be helpful to other people.
