Do we need to calculate the mWat_flowOut
if the only output is the dmWat_flow
?
If you also want to output it, better change it to become an output connector. And change the parameter name as mWatOut_flow
.

Change the section:
dmWat_flow = (XiOut.Xi[1] - XiIn.Xi[1])*V_flow*rho_default;
TDryBulIn = XiIn.TDryBul;
TWetBulIn = XiIn.TWetBul;
p = XiIn.p;
TDryBulOut = XiOut.TDryBul;
TWetBulIn = XiOut.TWetBul;
p = XiOut.p;
to be:
connect(TDryBulIn, XiIn.TDryBul);
connect(TWetBulIn, XiIn.TWetBul);
connect(p, XiIn.p);
connect(TDryBulOut, XiOut.TDryBul);
connect(TWetBulIn, XiOut.TWetBul);
connect(p, XiOut.p);
dmWat_flow = (XiOut.Xi[1] - XiIn.Xi[1])*V_flow*rho_default;
and change the TDryBulOut
to be an internal connector.

May not need to use the parameters. We can directly set the numbers to the Modelica.Blocks.Sources.Constant
instances.

We would like to retain the parameters since they are being used as inputs on various signal source types like constant and ramp. Will be easier to change these values through parameters on all instances

@JayHuLBL We have addressed the comments above, as per the individual responses. Please review the PR when you get a chance. Thanks! |
@JayHuLBL I am submitting this PR to merge the evaporative cooler models. Please create a development branch for the same on the LBL repo, so that I can rebase this PR on to it
