Re: [TRNSYS-users] heat exchangere

Elly,
If you have the TESS HVAC library, there are a number of heat exchangers with controlled outlet temperature models in there. If not then you will need to use a variable speed pump (Type3) , the heat exchanger, and (most likely) a PID controller (Type23). 
Best,
 David

Dear Transys-user,

I'm simulating, with trnsys 16, a plate heat exchanger for district heating
substation. I'm using type 5b, is it correct?
There's a control unit that in function of external temperature and the hot-
side outlet temperature (secondary pipe) open or close (%) the valve in the hot-
side inlet temperature (primary pipe).
Can someone tell me how can i model a control unit? which types can i use?

Thanks in advance,
Elly
