Enthalpy calculator
The function block calculates the following based on inputs temperature and
relative humidity:
Purpose
Function range A (inputs Temp A and RelHu A):
Function range A
Enthalpy A
Absolute humidity A
Dew point temperature
Wet bulb temperature
Function range B (inputs Temp B and Rel Hu B):
Function range B
Enthalpy B
Absolute humidity B
Enthalpy difference (Enthalpy A Minus Enthalpy B)
The results of the calculations are provided as DC 0...10 V signals
or
as internal,
analog signal.
