[TRNSYS-users] modellling a transpired (perforated) solar collector facade

[Fred Betz]

Eleni,

The simple way of modeling a transpired solar wall is using RETScreen from Natural Resources Canada, which is free.

RETScreen doesn't allow all the flexibility described below, but there are multiple types of products in the database so you could use that as a starting point for comparing characteristics.

I am told that it is possible/difficult to model a transpired solar wall in TRNSYS, but I have never tried it.

Good luck. Let us know how it goes.

Subject: [TRNSYS-users] modellling a transpired (perforated) solar collector facade

Hi All,

I am posting this on behalf of a colleague who is looking for a suitable simulation software for a particular research project.

I'm looking for a method of modellling a transpired (perforated) solar collector facade on a large building.  I'd like to look at different variables (e.g. pitch and size of perforations, distance between facade and wall, airflow, meteorological variations, etc) and how this affects the relationship of the collector with the building and any existing/backup heating/cooling services.

Could anyone reply with a comment on whether TRNSYS is suitable for this modelling exercise and if yes, what are the components required (if any) from the TRNSYS-related libraries or any others available out there?

Thank you in advance for your replies,

Regards

Eleni
