PROBLEM TO BE SOLVED: To provide refrigerant heat properties calculating method for actualizing highly accurate calculation at a high speed to obtain a refrigerant heat properties and for actualizing the converging stability of a solution.;SOLUTION: By using a source data processing means for obtaining source data for the refrigerant heat properties, a regression treatment means by applying regression treatment to a specified high order polynomial with the refrigerant heat properties to be found out of the source data for the refrigerant heat properties to obtain the coefficient of the high order polynomial, and a solution and root selecting treatment means for solving the high order polynomial for which the found coefficient is substituted to obtain the roots of the high order polynomial out of which an effective root is selected, a positive equation is obtained which represents the relationship of the refrigerant heat properties to be found. The positive equation is used for calculating the refrigerant heat properties.;COPYRIGHT: (C)2006,JPO&NCIPI
