Subject: [TRNSYS-users] Type 112b Motor Efficiency
Dear Trnsys Users,
I am modelling an AHU system in Trnsys for a part of my Master Thesis. I use Type 112b to model a fan and I just discovered that the motor efficiency parameter input of the fan has no impact on the power consumption but it is only used in the equation to calculate heat losses to the air from the pump.
But this value works backwards in the equation in my opinion. The outlet air temperature rises with a greater efficiency value, which means more heat transfer from the fan motor to the air stream is bigger with a more efficient motor!? . Should not it be the other way around?
Another point is, when the motor heat loss fraction is 1, changing the efficiency of the motor does not make any difference at the outlet air temperature.
If anybody has any experience with this type, a help would be much appreciated.
Thanks in advance.
Emir

But when i want load the data variable and i select zone, the outside and inside variable can't be load automatically.Therefore, i can't animate de temperature profil in Google Sketch UpAny help will be appreciated!Thank you very much--BENFEDDOUL AnouarEnergy Efficiency Trainer At IFMEREE Oujda06 66 03 98 85

_______________________________________________Hey,
When loading the data variables, make sure you choose the corresponding variable type in simulation studio. Don’t mix surfaces and zones or different outputs as temperature with rel. humidity.
Hope that works!
For more information please read the 04-MathematicalReference, 4.7.6. Type 125: Trnsys3D Result Visualizer for SketchUp™.
Best,
Christoph

Betreff: [TRNSYS-users] Loading temperature data in Google Sketch Up
Dears,
Could anyone can tell me why temperature data of TRNSYS can't be load in Rendering Settings in Google Sketch Up:
The problem is that i can load the data source from the .eso file generate by Type 125. But when i want load the data variable and i select zone, the outside and inside variable can't be load automatically.
Therefore, i can't animate de temperature profil in Google Sketch Up
Any help will be appreciated!
Thank you very much
