Temperature difference at the hot fluid inlet (cold and hot fluids)
The temperature difference of the backflow gas at the hot side of a plate heat exchanger is very important; the cooling loss resulting from this is known as the sub-reheating loss, and it has a significant impact on production
The difference between the inlet temperature of the hot fluid and the outlet temperature of the cold fluid should generally be kept below 4.5; the lower this temperature difference, the better, as it indicates that all the cooling capacity is utilized with no loss of cooling effect
The hot-side temperature difference refers to the temperature difference between the cold and hot fluids at the hot side of the main heat exchanger；
I think the original poster is doing internal compression directly, which is why they care so much about this issue.
Reply to 4# Liu Xue: It seems that the modification we carried out, which involved a temperature difference of over 60 degrees, wasn’t based on any proper evaluation. Huh
Reply to 7# nmgsb: What’s the temperature difference between those two points of yours? Why is it set so high? If what you say is true, then the temperature at the pipe outlet should be below zero by now
