Hello everyone,
Is it acceptable to have crossover temperature in a countercurrent heat exchanger?
Or we need to change the design of the heat exchanger?

The cold side outlet temperature can be above the hot side outlet temperature in a countercurrent heat exchanger. Is that what you mean by a crossover temperature? When designing, choose the most economical design that meets all the requirements.

hi,
Nobody says it's desirable, just a matter of fact and cost.
