A research team has made a groundbreaking discovery in the quest to replace hydrofluorocarbons in refrigeration systems with natural refrigerants such as water and alcohol. Their study involved carrying-out a liquid-to-gas phase transition via a nanosponge, a soft, elastic material equipped with small nanopores less than 10 nanometers. Their findings could lead to more efficient refrigerants with a smaller carbon footprint.
Refrigeration systems are widely used in air conditioners and refrigerators. Conventional systems use hydrofluorocarbons as a refrigerant. However, hydrofluorocarbons are super pollutants. Their Global Warming Potential is about 1300 times higher than that of CO2.
The team of researcher...
