When analyzing the heat exchange process using the pinch analysis technique, if heat flows from above the pinch point to below it, which of the following statements is incorrect regarding the external utility requirements? (A) The heating load increases, while the cooling load decreases. (B) The cooling load increases, while the heating load decreases. (C) Both the heating load and the cooling load increase. (D) Both the heating load and the cooling load decrease. The correct answer is C. What if heat flows from below the pinch point to above it? Which one should I choose?
The temperature at the cold end below the clip is lower than that at the upper part; to meet the original request, additional work is required.
