Troubleshooting Heat Exchanger Error Msg

Click For Summary
SUMMARY

The forum discussion focuses on troubleshooting a persistent error message related to a heat exchanger system. Users are experiencing difficulties despite attempting various combinations and sequences below the pinch point. The conversation highlights the importance of providing clear, high-resolution screenshots or textual descriptions of the error messages and software being used, as this information is crucial for effective troubleshooting.

PREREQUISITES
  • Understanding of heat exchanger operations and pinch analysis
  • Familiarity with error message diagnostics in thermal systems
  • Experience with software tools used for heat exchanger simulations
  • Basic knowledge of thermodynamic principles related to dTT and dH
NEXT STEPS
  • Research common error messages in heat exchanger software
  • Learn about pinch analysis techniques for thermal systems
  • Explore troubleshooting methods for heat exchanger performance issues
  • Investigate software options for heat exchanger simulation and diagnostics
USEFUL FOR

Engineers, thermal system designers, and technicians involved in heat exchanger design and troubleshooting will benefit from this discussion.

How should I do to eliminate the error message?
In what direction should I approach the question? (I have tried difference combination and sequences of the heat exchanger below pinch, all seems not working)
Thanks

That screen shot you posted is too low resolution to read any of the text. I can't see what software you are running or what the error warnings say.

Can you post that information in text rather than a screen shot?
 
It is hard to type the diagram here, let me post the pic again in Imgur, the link:




Thank you
 
this is also what I got with dTT and dH fulfill the requirement, yet with the same error message
