A kind of curve-fitting method was established to simplify the thermal properties of R410A,which is known as the main substitutes of the phase-out refrigerant R22.The range of curve-fitting models was-40-60℃ for saturated temperature and 0-60℃ for superheated temperature.Meanwhile,the relative error was analyzed.Compared with the reference source data,the result showed that the accuracy of these models met the requirements for engineering calculation and guaranteed the calculation speed and stability.This curve-fitting method can be applied to simulation and optimization calculation of the device or process real-time control.
