[TRNSYS-users] Insert new equation

[Adrien JEZEQUEL]

Dear Samir,

To define your temperature air flow, you can use forcing functions from 
"Utility" Library:

- Forcing Function 1 = 1 from 9h to 18h
- Forcing Function 2 = 1 from 18h to 24h

Then, connect the ouputs to an equation window:

- Output Forcing Function 1 = Input1 Equation Window
- Output Forcing Function 2 = Input2 Equation Window

define an other input for the external temperature (which can be called 
"Text")

Then define an Output in equation window :

Output = 23*Input1 + Text*Input2

The output defined above will describe temperature air flow profile 
every day of the year.

Concerning the equation functions see the manual 'Volume 7- TRNEdit', 
section 7.2.9 'The EQUATIONS Statement" for a complete description.

Best regards,

Adrien
