As the latest HFO refrigerant, R452A has been widely used in low-temperature and ultra-low-temperature systems. Today I will introduce R452A refrigerant in detail.
Introduction of R452A refrigerant
R452A refrigerant is an HFO refrigerant, non-ozone depleting, non-flammable boiling mixture, designed as a low global warming potential (GWP) replacement for R-404A and R-507, suitable for existing and new systems Low and medium temperature applications.
Use of R452A refrigerant
R452A refrigerant is used in volumetric, direct expansion, medium and low-temperature commercial (large refrigerated vehicles, light refrigerated vehicles, refrigerated containers), and industrial and transportation refrigeration systems. R452A refrigerant is suitable for new equipment installation and existing equipment renovation. It can provide similar energy efficiency and improve environmental characteristics without increasing the discharge temperature of the compressor.
Composition of R452A refrigerant
Mole percentage: R32 accounts for 21.8864%, R125 accounts for 50.8838%, and R1234yf accounts for 27.2298%.
Mass percentage: R32 accounts for 11%, R125 accounts for 59%, and R1234yf accounts for 30%.
