PC PSYCHROMETRIC PROPERTY PERMUTATIONS AND PROCEDURES.

Author(s) : GUY P. C., WEPFER W. J.

Summary

THE PAPER PRESENTS A TUTORIAL ON THE COMPUTATION OF PSYCHROMETRIC PROPERTIES ON THE PERSONAL COMPUTER. SPECIFICALLY, THE IDEAL GAS APPROXIMATIONS ARE USED TO ILLUSTRATE THE EASE WITH WHICH ONE CAN COMPUTERIZE PSYCHROMETRIC CALCULATIONS. THIS APPROACH REQUIRES ONLY THAT THE RELEVANT PSYCHROMETRIC EQUATIONS ARE IN ALGEBRAIC FORM AND INPUT THREE INDEPENDENT THERMODYNAMIC PROPERTIES FROM AMONG THE DRY-BULB TEMPERATURE, PRESSURE, WET-BULB TEMPERATURE, DEW-POINT TEMPERATURE, HUMIDITY RATIO, RELATIVE HUMIDITY, SPECIFIC HUMIDITY, MOLE FRACTIONS, MASS FRACTIONS, AND/OR SPECIFIC VOLUME. THE PROGRAM COMPUTES ALL PROPERTIES INCLUDING ENTHALPY, INTERNAL ENERGY, ENTROPY AND AVAILABLE ENERGY. THE RESULTS GENERATED BY THIS APPROACH ARE COMPARED TO THOSE BASED ON THE HYLAND-WEXLER FORMULATION, AND A GRAPHICAL DISPLAY OF THE ACCURACY FOR THE ENTHALPY AND ENTROPY IS SHOWN.
