[TRNSYS-users] control a Wall temperature with experimental data

[Freppel, Wirich]

Michaël,

My apologize for this late reply, the mail did not end up in my inbox folder...for some reason
Indeed I'm trying to model an entire zone in Type56, with an exception on a wall. I will have a look at your paper. Looking at what you're saying, it could answer to my question.

Thanks a lot for your help.
Best regards

Wirich

Wirich,
I am not sure what you are trying to model (just the wall or the zone in Type 56), but it is possible to remove a wall from a Type 56 model and simulate that wall with another component in TRNSYS. The method is described in a paper by Delcroix at al. for a Type that models walls with PCMs, but it can be applied with any component (see the appendix in the paper):

Delcroix, B., Kummert, M., & Daoud, A. (2017). Building-scale experimental validation of a new model for walls with phase change materials. Science and Technology for the Built Environment, 23(6), 1049-1062. https://doi.org/10.1080/23744731.2017.1333353<https://urldefense.proofpoint.com/v2/url?u=https-3A__doi.org_10.1080_23744731.2017.1333353&d=DwMFAw&c=tkg6qBpVKaymQv9tTEpyCv5e23C4oKrSdZwjE7Q68Ts&r=jkZ7Sl1EHKZyrfFdxjuC9NFArESmikqxVG2m5ksERtM&m=DQn7i4W6Zg1-tzWAfaFWa-D7nrW0jBmS1WEF1eyxVwo&s=ix8qLnEQ-0lA_9e82-PAO-YGgHLvxdcHMtHbP6Ujh2M&e=>

Subject: [TRNSYS-users] control a Wall temperature with experimental data

Dear TRNSYS users,

I try to do thermal simulations on an experimental platform that was built in my lab. It is a single airnode room. For a specific application, I would like to control the temperature of one wall with some data I got from temperature measurements.
So , to summarize :
-          I measured the inner surface of the wall during a period of time in the experimental platform
-          I want to use this data as an input in TRNSYS to control the temperature of the wall (indoor surface)

I don't really know how to set up this in TRNSYS, as I have the feeling that I must "deactivate" TRNSYS calculation for this wall... Is it even possible to control the inner temperature of a wall ?

Thanks in advance for your reply.

Best regards
