Performance characteristics of eco-friendly Seawater Ice slurry maker using Alternative Refrigerant R-1234yf

Nowadays, interest in environmental issues is increasing, and refrigerant regulations are getting stricter through the 1989 Montreal Protocol, the 1997 Kyoto Protocol. As a representative example, the slurry ice making device used to maintain the freshness of fish, caught by fishing boats is also using a refrigerant. And this conventional refrigerant has high GWP, so it will be regulated. However, since there is no suitable alternative refrigerant for refrigeration so far, in this study, HFO-based R-1234yf refrigerant was used as a working fluid, which has been widely used recently in vehicle air conditioning. Also, this paper represents whether this refrigerant is suitable for using in refrigeration system. From this experiment results, R-1234yf refrigerant can be judged to be sufficiently usable for refrigeration system.
