Dear TRNSYS User
 
I checked a simple steady state problem in trnsys15.
I have a room: 50 m^3 with an air change rate of 0.7 per hour and a source
of 0.3 kg/h water. The outside and inside temperature is 20 °C and the
outside relative humidity is 0 (or 0.000000001%). 
 
The result of TRNSYS type 56 is 49.0263 %
 
but the result of my calculation is 49.572% (see enclosed pdf file).
 
 
The differences comes with the source inside the room. That means I go
confirm with the psych - routine. 
 
Now my question is what makes the difference?
 
Thanks in advance
