[TRNSYS-users] TRNSYS-users Digest, Vol 176, Issue 22

Yeyson, 

The reason the outlet temperatures are different is that in the first
project you have a pump and a controller to modulate the flow through
the ground heat exchanger. In the second project you have no flow... 

The error you refer to is that Type 99 cannot read the external data
file. Double click on the External Files tab of Type 99 and select the
file it's supposed to be reading. 

I would suggest that you carefully review the example projects and
tutorials provided with TRNSYS as they can provide a lot of good
examples to help you through these basic problems.

On the other hand, I copied the type and pegged in another project (Fig 1), but I have this problem when running the project the outlet temperature is very different from the original (Fig 2 and 3), the performance is totally different. As another option, I copied the whole project, all Type, and pegged this information in the window for the second project, but I have this problem and I don´t understand (Fig 3), why is this happening?

But I do have to point out that Type 997 is NOT intended to be an earth-to-air heat exchanger. Type 997 assumes a liquid inside of the pipes and not air! There are earth-to-air heat exchangers available from 3rd party vendors.

I am simulating an Earth to Air Heat Exchanger with specific features, I finished it and I obtained the results, but in the other project, I simulated an office building. I want to know how to take the EAHE results and to apply in the building if this is in other windows. Is there a type that imported the information? or It's possible to copy the 997 EAHE type in the other project and TRNSYS recognizes the same characteristics. For more information, I attach the figures. Thanks.
