What type of refrigerant is utilized on board the ships?

The utilization of R-134A as a refrigerant on board ships is due to its favorable properties, particularly its low environmental impact compared to many traditional refrigerants. R-134A is an HFC (Hydrofluorocarbon) refrigerant that does not deplete the ozone layer, making it a more environmentally friendly choice in compliance with regulations regarding ozone-depleting substances. Its thermodynamic properties make it effective for a variety of cooling applications, which is critical in marine environments where reliability and efficiency are paramount. Additionally, R-134A operates well at a range of temperatures that are typically encountered in shipboard refrigeration systems. This makes it well-suited for maintaining optimal temperatures for cargo, provisions, and living quarters on ships, ensuring both safety and comfort during voyages.
