Dear Karthick, in the Absorber (component 9) the primary fluid (cold fluid) is undergoing temperature drop. That should not happen. That could be the cause of negative mass flow rate in the Absorber.
Negative enthalpies occur in Cycle-Tempo due to the way in which the reference temperature is defined. Since only the enthalpy differences matter for evaluation, negative enthalpies are not to be worried about.

You may be implying heat exchanger effectiveness (=actual heat transferred/maximum heat transfer possible)?
As far as I know, there is no way to specify that parameter in Cycle-Tempo. One should compute the exit temperature manually using the effectiveness and input it as TOUT or whichever temperature is not known.
In Boiler component (evaporator), we can specify the boiler efficiency.
In Condenser, again, like in heat exchanger, it is not possible to specify the effectiveness.

I would like to correct myself. Text output can be printed as a pdf file. In the text output window, choose File–>Print. You can choose to print to pdf at this point. I did it and it worked.

Dear Harish, it is not clear to me how exactly you are going to incorporate a geothermal source in this VCR system. You can try to draw a simple labelled schematic diagram of what you intend to do and upload here.
It would be better if you can provide a clear problem statement.

T-S diagrams can be plotted only when the working fluid is water/steam. For other fluids, you can collect the temperature and entropy data using View–>New Table option, transfer the data to a plotting software and plot the T-S diagram there.

While installing, at a stage, you will be prompted to provide the license file (or key). Then browse and give the license file (or paste the key).
For Cycle-Tempo, you can place the license file in the program files–>Cycle-Tempo folder.
