Computer program for determining the thermodynamic properties of Freon refrigerants
Abstract
A subroutine for determining F11, F12, F13, F14, F21, F22, F23, F113, and F114 was written. The program can evaluate a thermodynamic state for these refrigerants given any of the following pairs of state quantities; pressure and quality; pressure and entropy; pressure and enthalpy; temperature and quality; temperature and specific volume; and temperature and pressure. These six pairs of knowns allow the user to analyze any thermodynamic cycle utilizing a refrigerant as the working fluid. The Downing form of the Martin equation of state was used. A flow chart is presented along with a listing of all subroutines required.
