[TRNSYS-users] adding thermal capacity

Dear Federico,
The STEC library provides a thermal capacity model (type 306 - Lumped mass to simulate thermal capacity of components). Perhaps this could be of use for you. You can have more information at http://sel.me.wisc.edu/trnsys/trnlib/stec/stec.htm
Best regards,

Federico,

 You'd need to modify the Fortran code and make a new Type, then compile it and make a dll. The Type5 heat exchanger model is quasi steady state and you'd need to turn the solution into that of a first order differential equation in order to account for the mass of the exchanger.

kind regard,s

 David

Hello everyone,

I would like to add some thermal capacity to a heat exchanger (type5) to take into account the metal mass of a flat plate heat exchanger. Is there any one with some suggestions/ideas on how this can be done with some workaround?

Thanks in advance and best regards,

Federico
