WebbIn designing heat exchangers, one should avoid the steep portion of the curves of . F versus P, because small errors in estimating P can cause large changes in the value of F. A misleading rule of thumb is that F ≥0.8, but the correct idea is that the region of steep fall-off in the curves should be avoided. 5 Webb29 jan. 2011 · Every situation needs to be evaluated on its own merits and some of these rules will conflict with the others.

"Webbthe first figure, you can see that the heat rejection at the evaporator and condenser change from air to water as you move from split system to water cooled chilled water system. This change in heat rejection from air to water greatly improves the efficiency because the heat transfer is much better with water due to its increased heat capacity.
