Why is there a 30% difference in the thermal load of hot and cold fluids between the data in ASPEN and those in HTRI?

So why is there a difference of nearly 30% in the heat loads of the hot and cold fluids? I wonder if others on this forum have encountered similar problems
This situation is not normal. Compare whether the material property parameters in the two software are consistent.
I directly exported the data from Aspen to HTRI
What are your operating conditions like, and what equipment are you using?
Organic working fluid evaporator, liquid vaporization, phase change involved
Check if the process conditions have changed
