Résumé

This paper deals with the influence of R12 fluid replacements on energy efficiency and global warming expressed by values of COP and Total Equivalent Warming Impact (TEWI). Experimental investigations are presented which relate the use of refrigerants R134a, R401A, R409A, R22 and the mixture of R134a with R12 to the values of COP and TEWI of refrigerating system in comparison with R12 application. It is shown that the use of R134a, R401A and R409A refrigerants enables the increase of COP coefficient and significantly reduces the value of TEWI in comparison with R12 application.
