  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.
