From an investment perspective, the pressure drop can be reduced through process optimization by installing a large heat exchanger
One is better. Considerations from a process perspective. If management is a consideration, one is better.
This is likely related to the flow rate, or the temperature difference across a heat exchanger.
However, among the two processes in our factory, using two heat exchangers in series yields better results than using just one heat exchanger
Using two small ones in series increases the flow rate, thereby raising the heat transfer coefficient, and the effect is good.
The design configuration of the heat exchanger (whether to use one heat exchanger or two, in parallel or in series) affects the effective average temperature difference. It is recommended that the person asking this question consult GB151; actual data is necessary to determine which configuration is more appropriate, as otherwise it remains just speculation.
