After the paper "A General Computer Program of the Thermodyna- mic Properties for Fluorinated Hydrocarbons" written by this paper's authors, the authors have solved the problem of computer program for single stage compression refrigeration cycles for twelve freons. For theoretic refrigeration cycles, the input data supplied to the computer are only condensing temperature, evaporating temperature, superheated temperature at suction state and subcooling temperature before throuttling. For practical refrigeration cycles, some additional input data are neca- ssary. Output data of this program are thermodynamic properties at the characteristic points of the theoretic refrigeration cycle and the chara- cteristic values of the cycles. Using this program the calculating speed and accuracy can be increased. Inaddition, the paper has recommend a new thermodynamic calcul- ating method for using hermetically sealed compressor in the refrigera- tion cycles.
