[TRNSYS-users] Insert equation

[Stefan de Kool]

Dear Samir,

 

You could use something like the following:

 

Tsouf = 20*LT(Text,16) + (..)*GE(Text,16)*LT(Text,32) + 18*GT(Text,32)

 

With (.) = Input2-(Input3/(0.34*MAX(Input4,0.0001))

 

The LT, GE and GT are boolean equations (less than, greater or equal than,
greater than) resulting in a factor of 1 if the condition is satisfied and 0
if not. So for eqample Text = 18,5 would give:

Tsouf = 20*1 + (.)*0 + 18*0 = 20

 

Good luck

Stefan de Kool

 

Met vriendelijke groeten,

Hello,

I try to model this schedule :

If Text<16 Tsouff = 20

If 16<Text<32

Tsouff = Input2-(Input3/(0.34*MAX(Input4,0.0001))

If Text>32

Tsouff = 18

And I don't know how integrate these conditions with "equation".

Best Regards
