In these days of transition to new, more environmentally friendly working fluids, there is a definite need for good data and models of basic thermodynamic and transport properties of both pure compounds and mixtures to be used for cycle calculations and equipment redesign.Two annexes of the IEA Program on Advanced Heat Pumps have dealt with such data, namely Annex XIII-State and Transport Properties of High Temperature Working Fluids andNonazeotropic Mixtures and Annex XVIII-Thermophysical Properties of the Environmentally Acceptable Refrigerants. In this paper, highlights of these two annexes are presented.A sensitivity analysis (from Annex XIII) gives an estimate of how accurately these basic data need to be known to reach a certain accur...
