In this paper, the author points out that there exist two different conditions of suppling low temperature heat. One is the unvariance of mass rate of the hot fluid, and another is the unvariance of amount of the suppling heat. From the thermoeconomic respect, these two conditions demand the working fluids differently or even contrarily in some thermophysical properties.Then, from the thermodynamic theory and the characteristics of electric generation from low temperature heat, the author has derived four formulas for calculating the optimal temperatures of vaporization and condensation of working fluids and other four formulas for calculating the correcting coefficients.Through a large amount of calculations for various working fluids and various parameters, these formulas are proved to be reliable and accurate. These formulas will serve as a convenient means for the thermodynamic calculations in designing power plant of low temperature heat, and a great deal of time spent on these calculations will be saved.
