Guante Refrigeration Cascade Refrigeration Technology

Most low-temperature cascade refrigeration units areR22/R13 is a refrigerant. To meet environmental protection requirements,Guante RefrigerationadoptR404A/R23 as refrigerant. Among them, R404A is a mixture of R125 (standard boiling point -49 ℃), R143a (standard boiling point -47.2 ℃), and R134a (standard boiling point -26.1 ℃) in a mass fraction of 44:52:4, which has the properties of....R22 (standard boiling point -40.8 ℃) has similar thermal and physical properties, with a standard boiling point of -46.6 ℃, zero ODP and CLP values, non-toxic, high safety, and a GWP value of 4540. Experiments have shown that compared with the same unit using R22 as refrigerant, the refrigeration capacity of a refrigeration unit using R404A as refrigerant will slightly increase, but its power consumption will increase even more. Overall, its COP is slightly lower than that of an R22 unit, which is an unfavorable aspect [2-3]; R23 standard boiling point -82.1 ℃, zero ODP and CLP, non-toxic, high safety, slightly higher GWP, about 14800 [4]
