ASPEN heat exchanger module error message!
Thread Content
------------------------------------------------------------------- ** ERROR: Invalid hot stream temperature specification. T-SPEC = 2.8815000D+02 is less than TCIN = 2.9991587D+02. --------------------------------------------------------------- The HeatX module is being used. Could someone please advise me on how to make the correction? Thank you!
It is clearly unreasonable for the inlet temperature of the hot stream heat exchanger to be lower than the outlet temperature of the cold stream heat exchanger. Check: Is there an error in the input of the cold and hot flow rates, or are the cold and hot flow streams incorrectly connected to the heat exchanger?
Hot fluid: 40 -----》10 Cold fluid: -10 ----》15 The same prompt appears again.
Why not upload it and take a look? I don’t think you would make such a silly mistake either. :D
Thank you. I’ve taken care of it.
What was the final cause?
How do I adjust the temperature? I’ve encountered this problem too
