Re: [TRNSYS-users] Exporting file




Hi everybody,
Can anyone tell me, how to activate 'Export as....' option from the File menu? I have followed the steps in section 1.9 of TRNSYS 16- Getting Started. However did not manage to export the file after saving in TRASYS 16\Studio\Proformas\My components... Whether this could be because of no FORTRAN/C++ is loaded in the PC?

Thanks.
Papia

Papia,
Type91 calculates the heat transfer rate across the heat exchanger based on the conditions (temperature and flow rate) at the inlets and on the effectiveness specified by the user. The place you need to start is with the 05-Mathematical Description manual to resolve the equations that Type91 uses so that the heat exchange rate is known and some other variable (outlet temperature of one side of the HX for example) is unknown. As Diego and I mentioned in our previous emails, you would then need a Fortran compiler in order to write a new component for TRNSYS.
Kind regards,
 David

Dear Diego,
Thanx for your interest.
In my problem, I am using 'type 14 h' to read a variable cooling load (let's say within 0 to 24 hr). Next, I am linking this to a 'type 91' HE through an
appropriate equation 'equa' (needed to convert the unit). For the HE of
'type 91', I would like to link the 'cooling load' in terms of 'heat
transfer rate' in the input list. So that new input list could be: heat
transfer rate, hot side flow rate, cold side inlet temp, cold side flow
rate. The output list may remain same or could cut down one/ two. My point
is, how could I modify the component 'type 91' to cop with variable load?

best regards
Papia
