Simple Flow Mixer to Calculate Outlet States
by S. Gabel for ASHRAE
Revised for TRNSYS by N. Blair and R. Schwarz
This model was adapted strictly for use with the TRNSYS Program by
the Solar Energy Laboratory.
This subroutine calculates the outlet states for a mixing process based
on simple conservation equations. The outlet flow rate is the sum of the two
entering flow rates. The outlet temperature is the weighted average of the
entering streams, using the flow rates as the weighting factors. While the
nomenclature and mathematical description use temperature as the calculated
state variable, the subroutines can also be used for calculation of any
conserved state variable. Component 1204 calculates the inlet states for the
flow mixer.
Sample input and output are included in the source code.
