Résumé

The paper shows the thermodynamic properties of alternative refrigerant mixtures for R404A that can be used in the refrigeration systems and also in the calculation of COP and TEWI systems. As a result of the new legislative regulation on an international level regarding the refrigerants, new ecological alternatives in terms of global warming potential (GWP) must be found in the following years. The blending component has been simulated in different percents with the RefProp software. It contained the following refrigerants: R125 (CF3CHF2), R143a (CF3CH3) and R152a (CH3CF3). From the main refrigerant R404A, component R134a has been replaced by R152a which has the advantage of a lower GWP.
