Experimental drop-in comparison of R516A and R134A for water-to-water refrigeration applications [PDF]
Libro de actas XI Congreso Ibérico y IX Congreso Iberoamericano de Ciencias y Técnicas del Frío Cytef2022. Avances en Ciencias y Técnicas del Frío - 11, 2023 R134a is still one of the most used hydrofluorocarbons (HFCs) in refrigeration and air conditioning applications. However, it should be phased out in the coming years because of its high global warming potential (GWP). The refrigeration sector needs to find as soon as possible technically suitable alternative refrigerants.
