How is the area of these two plate heat exchangers calculated?
Thread Content
Gentlemen, I have a small project that requires two plate heat exchangers. The specific parameters are as shown in the photos. I did a rough calculation of the heat exchange area for these two plate heat exchangers; according to my calculations, the PHE-4055 should use a plate heat exchanger with an area of 100 m2, while the PHE-4054 should use one with an area of 12 m2. The heat exchange area calculated by the procurement department and sent by the heat exchanger manufacturer differs greatly from the value I calculated. Friends, if you have time, could you help me estimate roughly what size would be appropriate for these two plate heat exchangers?
Note: For the parameters in the photos, those marked with * must be filled in by the supplier.
The key is to calculate the average heat transfer temperature difference accurately!
The first one is about 70 square meters, and the second one is about 6 square meters, based on rough estimates.
Thank you; it seems that the figures calculated by the plate heat exchanger manufacturer are incorrect.
I think it’s probably the inconsistency in the overall heat transfer coefficients calculated for different plates, which leads to significant variations in the heat exchange area
Plate heat exchangers require not only a sufficient heat exchange area but also adequate flow channels.

I read the reviews; everything they chose for you was wrong. They are all on the larger side; to keep costs low while still achieving effective heat exchange, it is necessary to use multiple processes
