[TRNSYS-users] Stagnation Temperature

[David BRADLEY]

Anand,

   When you are looking at the Type65 plot window, hold down both the 
ctrl and shift keys and the line labels will be replaced with the 
/actual /value of each output. What you are looking at on the screen is 
a plot of values that are visually interpolated between actual values at 
each time step. It may be that the stagnation temperature jumps at the 
same time that radiation is incident on the collector surface in such 
quantity that the gains outweigh the thermal losses of the collector but 
that the plot confuses things a bit by its visual interpolation.

kind regards,

David
