Abstract
In a study of a complex thermal system where fluids are used as werking media, it is
always necessary to calculate thermo-physical properties of the fluids involved. When such
a study is conducted by computer simulation, tabulated data of fluid properties are inconvenient
to use, especially if variations of the fluid properties are encomlCred. A
betterapproach is to make use of mathematical models representing the fluid in the
form of mathematical equations. This paper will outline the prodecure which may be
used to obtain such equations. A particular case of Refrigerant 12 is presented to
illustrate the modelling approach. Some important equations for determining R12 properties
are also presented. These equations are highly accurate as compared with the data published
by ASHRAE and HR.
