R 22 is one of the dominant refrigerants for marine applications.This refrigerant is a HCFC chemical; its substitution in the marine sector demands efforts done to indicate the right refrigerant.On reefers (refrigerated ships), the substitutes for R 22 are R 410 A, R407 C and R 404 A, since a single ideal refrigerant is not nominated.Available literature shows that R 404 A can be used in best conditions as a substitute for R 22. Thus, in this paper is given a comparison between R 22 and R 404 A resulting alike properties.In time of crisis, the maintenance of the existing R 22 equipment provides an economic benefit.This study deals also with the retrofit aspect
