Re: [TRNSYS-users] convection approach in TRNSYS 17

[David BRADLEY <d.bradley@tess-inc.com>]

Leen,
 My understanding is that the big change came between v15 and v16. In v15, you had Type80 to calculate the internal convection coefficient and you could couple Type56's surface temperature output to Type80's inputs, then connect Type80's outputs back to a userdefined Type56 input for the convection coefficient.

 With the release of v16 (and still in v17) the correlation was built into Type56 directly so a user has only to select "internal calculation" instead of the usual "constant," "schedule," or "input" for the inside convection coefficient. The correlation parameters can be adjusted using the "properties" button in the TRNBuild project window.
Best,
 David

Dear all,

 

can anyone tell me whether the approach for modelling internal convection has been changed from TRNSYS 16 to TRNSYS 17?

 

Thanks,

 

Leen
