2019年2月25日 · R-404A has it’s own pros and cons. Let’s take a look at some of them. Pros. R-404A provided an immediate replacement product for both R-12, R-22 and R-502. This allowed the world to stop using Ozone depleting refrigerants.

Freon™ 404A (R-404A) is a blended hydrofluorocarbon (HFC) refrigerant comprised of R-125, R-134a, and R-143a. It was designed to replace R-502 and R-22 used in commercial refrigerator equipment for low and medium temperature ranges. Its properties make it ideal for use in display cases, refrigerated vehicles, ice makers, and other applications.

What's the best replacement for the R404A refrigerant in refrigeration applications? Find details answers to all your questions related to R404A in this FAQ from Danfoss.

INHALATION: R-404A is low in acute toxicity in animals. When oxygen levels in air are reduced to 12-14% by displacement, symptoms of asphyxiation, loss of coordination, increased pulse rate and deeper respiration will occur. At high levels, cardiac arrhythmia may occur.

2024年6月11日 · R404a refrigerant is categorized as a hydrofluorocarbon (HFC) blend. It consists of three main components: 52% R125, 44% R143a, and 4% R134a. Each component plays a crucial role in determining the properties and performance characteristics of R404a.

R404A has been the standard OEM choice for commercial and industrial low temperature refrigeration. Available in 24, 100 and 800 lb. cylinders.

CHEMICAL PARAMETER: R-404a,Assay: Air & Other Non-condensable Gas (NCG) Water: All Other Volatile Impurities: High Boiling Residue: Halogenated Unsaturated Volatile Impurities

R-404A Refrigerant or R404/R404A Refrigerant is a mixture of chemicals similar to other HFCs such as R-410A or R-134A. R-404A isn’t as popular as the 410A or the 134A it’s main applications are for refrigerated trucks, grocery store freezers, and ice machines.

Similar PT and flow properties to R-502. Higher capacity than R-22, therefore requires TXV change.

Refrigerant R404A is a standard refrigerant blend used in low and medium-temperature refrigeration. It is the most common choice for commercial and industrial low-temperature refrigeration.
