Berechnung der Vergrößerung der Austauschflächen und Ventilationsleistungen beim Übergang von Wasser- auf Luftkühlung

Through use of a simple equation for the economic optimization of heat exchangers used to reject heat to the environment, a functional relationship is developed for heat transfer area and required system ventilator power. Thermal resistance has been neglected between the heat exchanger and heat rejecting fluid. It is found that for a system in which the heat absorbing fluid is air, both the required heat transfer area and ventilator power are 76 times greater than in a system in which the heat absorbing fluid is water.
