Abstract: The need to replace traditional refrigerants in marine refrigeration equipment with low-GWP alternatives is growing due to international climate regulations. This paper discusses the current status and potential of R290 (propane) as a long-term substitute in marine air conditioning systems. Compared to other refrigerants, R290 offers higher energy efficiency, low environmental impact, and compatibility with existing system designs. Challenges related to flammability are addressed through compliance with safety standards and technical solutions approved by major classification societies. Calculations of performance parameters under different climatic conditions support the feasibility of switching to R290 as a sustainable alternative.
