I am working on a time dependent study of heat flow in solids and fluids (air). I have an assembly of various materials and I am simulating a thermal electric cooler as a heat source (1.4W). I have a location for a thermistor in the assembly and a surface goal of 338K at that location. I would like to switch off the TEC when that surface reaches 338K. I cant quite figure out the F(goal) - Table dependency type. I have the dependent on goal set to the SG Min Temperature (solid) 1 which is my surface of interest. Then there are 4 options...
no matter what I do, it seems like the TEC never comes on and for some reason the temp at that surface drops to 0K.
My control value is 340K
And I am not sure if the dead band is supposed to be a value or a differential. The chart in the help section implies it should be a differential but I have tried it as 1K and 339K.
Ambient and all solids start at 293K
For the record, I am getting beleivable results in a steady state, The temp just goes to high.
Does anyone know how to use these switches?
