[TRNSYS-users] TRNSYS-users Digest, Vol 67, Issue 65

Thu Jul 29 04:23:26 PDT 2010

Roberto,

You can use this:

 if(Ta.LT.15)then
    Ta=15
     if(Ta.GT.23)then
       Ta=23
    end if
end if

Best regards,
Mariana

dear trnsys users,
I have to add the following algorithm into the equation:

if Ta < 15 ta= 15 and if Ta> 23 Ta=23

How can I do this?
Thanks
Roberto

Well, you have to combine the gt() and lt() functions.
Unfortunately, there is no if in the equation...

maybe I'm wrong, but I don't think you can program that into an equation.
If I were you I'd program it in a type. It is really easy, you need onw input 
and one output, and you could even program the type with two parameters max and 
min and these numbers (15 and 23) would be parameters and you could easily 
change them anytime you want.
Regards.

Roberto 

First you need to add an equation from assembly folder
Second, add input as tainput 
Third, add output as taoutput
Forth, insert this expression on the taoutput "   
lt(tainput,15)*15+gt(tainput,23)*23   "   for sure without " "
Just this

Hello, Roberto.

You can define an output (say Ta1) in the equation proforma where

Ta1=Max(Min(Ta,23),15)

You can also use 'min' and 'max', for your example:

max(min(Ta, 15),23)

You can also use 'min' and 'max', for your example:

max(min(Ta, 15),23)

 - Nikolai
---------------------------------------------------------------
That's a good one, but it would be the opposite

min(max(Ta, 15),23)

anyway, this is definitely the best solution, you don't have to program 
anything.
