Re: [TRNSYS-users] Changing the role of a standard component

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

Dear Papia,
Changing a component is more than changing the proforma. You need to change the mathematical formulation, which is done in a Fortran compiler. If you need to modify a standard component, please feel free to send me a more detailed description of what you need and I may be able to help you. 
Best regards,

Diego

Dear TRNSYS users,
I have just started to use TRNSYS for centralized cooling system and I am just a novice. I would like to know If I change any of the output variable to an input variable or vice-versa to a component, do I need to generate new component? If not, I am not able to change any of the variable properties from the Proforma dialogue box even after saving the changes?
btw I will highly appreciate If any body like to share a basic central cooling model with me. 

Best regards
Papia
