HFC: R-290

R-290, a hydrocarbon refrigerant falling under the category of hydrofluorocarbons (HFCs), is primarily composed of propane and is characterized by its low global warming potential. A molecular structure consisting of hydrogen and carbon atoms, R-290 is hailed as an environmentally friendly substitute for conventional refrigerants. Renowned for its thermodynamic efficiency, especially in medium to very high-temperature applications, it exhibits lower vaporization heat and improved performance in cold conditions. While R-290 is non-toxic, its flammable nature necessitates cautious handling. Economically advantageous, R-290 requires 45-60% less refrigerant compared to some alternatives, emphasizing resource efficiency.
