Xiao,
a parameter is something you set in the beginnning of the
simulation that characterizes your specific component, while an input is
something that varies throughout the simulation and where your component with
its characteritics responses to. You can see it as the parameters being the
coefficients of the equation and the inputs being the variables....
Could you be somewhat more clear on the second part of the
question? It might help if you give the sequence of the components and what is
passed on as variable and what you actually want to do ...
kind regards,

Subject: [TRNSYS-users] Questions about
components
Hi,
I have a question about the component, such as single speed
fan (type 112b) and Auxiliary Heater (type 92). What is the difference between
parameter and input? For the single speed fan, I used the different rated flow
rate (parameter) and the air flow rate (input). What is the actual flow rate
that TRNSYS going to use. Also, I connected the fan to the auxiliary heater. I
connected the outlet air temperature to the inlet fluid temperature. I thought
I cannot change the inlet fluid temperature because the inlet fluid
temperature is depended on the outlet air temperature of the fan. But when I
go to the input tab for the auxiliary heater, I can still change the inlet
fluid temperature. I have no idea how does it work. Thank you very much for
taking your time to answer these questions.
Xiao
