The Calculation of Over-all Volumetric Enthalpy Trani, fer Coefficient in Cross-flow Cooling Towers

Abstract

This paper proposes two analytical methods to obtain the over-all volumetric enthalpy transfer coefficients incross-flow cooling towers with the idea of cross-fiow heat exchangers, assuming that the actual satulated enthalpy of the air can be numerically determined as the first degree in temperature and the numerical values calculated by these two methods is compared with the values of the graphical method reported by Uchida.
As the result, authors find that the methods rePorted in this paper are considerably resonable and further it becomes clear that the numerical values of over-all volumetric en thalpy transfer coefficient for cross-flow cooling towers can be calculated more easily by these two methola than by the past methods.
