[TRNSYS-users] Type 99 and units

[pseudomino at gmx.com]

Thank you,
 So I won't use these pull-down menus and use Equations instead to covert them.

 But I need a simple confirmation about my question : when I use a Type 99, the radiations :
 - are given in W/m2
 -mulitiplied by 3.6 to be outputed in kJ/hr.m2
 Am I right ?

Be very careful!!! You cannot change units using the pulldown menu in any component's inputs tab!!! A component's output values are passed directly to the appropriate component input values without any modification regardless of what units you have selected in the inputs or outputs tab. Those pulldown menus are only at the interface level; when the Studio writes the deck file, it writes everything in the base units of the proforma. Note that it is safe to change the units of parameters (and unconnected inputs) again because they will be converted to base units when the Studio writes the deck.

 We do not recommend using Type109. Type109's functionality was moved to Type99 (for the "user-defined" data file mode) and to Type15 (for the standard TRY file format). If you find references to Type109 in the documentation, please let us know so that we can refer to the proper component instead!

 David

 I have a doubt with my units. I use a Type 99 and I can see in the Outputs tab " *kJ/hr.m^2*" for the radiations.
 But in the exemple file (of user defined file), there is this line :
 " /<var> IBEAM_H <col> 5 <interp> 0 <add> 0 <mult> 1 <samp> -1  *!...to get radiation in W/m²*"
 So I wonder if I can ignore this unit in type 99 (kJ/hr.m^2) and just change it to W/m^2 in type 56's Inputs tab.

 By the way, I don't realy understand what is type 109 ? It is often mentionned in the user guide, but it seems that it is a generic component ?

 Thanks in advance
