R404A & R407C Refrigerant Gases

R404A Refrigerant: An Overview

Freon 404A (R-404A) is a hydrofluorocarbon (HFC) refrigerant mix consisting of R-125, R-134a, and R-143a. It was created to replace the R-507 and R-22 refrigerants used in commercial refrigerators for low and medium temperature ranges. Because of its qualities, it is perfect for use in display cases, refrigerated trucks, ice machines, and other uses.

Features and Benefits of R404A

Freon 404A is a nonflammable, low toxicity refrigerant with an A1 safety rating and qualities identical to the refrigerant it replaces. It has a global warming potential (GWP) of 3920 and zero ozone depletion potential (ODP).

When compared to R-507, Freon 404A has the finest overall characteristics. It has the same capacity and efficiency as R-507. It runs at equivalent physical and thermodynamic parameters, making it easy to migrate to new systems or adapt older systems. Freon 404A compressor discharge temperatures can be 9 °C (14 °F) lower than R-507, which may result in longer compressor life and greater lubricant stability. When replacing R-507 with Freon 404A, original equipment manufacturers (OEMs) recommend utilizing polyester (POE) oil in the compressor. Freon 404A will have the same operating range as R-507 after the oil change


Is R404A Safe for The Environment?

The ozone layer has been greatly harmed by the refrigerant R22. R404A is now the mainstream ecologically friendly refrigerant that is allowed and recommended by the majority of governments throughout the world, and it does no harm to the ozone layer. Furthermore, the difference in evaporator capacity between R410A and R22 decreases initially, then increases. The flow channel with the most circuits had the most heat exchange.

R22 and R404A have heat exchange rates of 4.40kW and 4.50kW, respectively. R404A had a higher heat exchange amount than R22, and the difference in heat exchange amount drops initially and then increases as the number of branches grows, with a maximum difference of 4.41 percent. R404A can be used in place of R22 and has a greater heat exchange rate. It is better for the environment and saves electricity.

Applications and Uses of R404A

New R404A plants will be restricted beginning in early 2020. The building of fixed refrigeration units that utilize a refrigerant with a GWP more than 2500 will be prohibited. 517/2014 EU F-gas Regulation).

R404 recycled: usage for maintenance will be authorized until the end of 2030. R404 is used at around 2000+ retail stores in UAE. There is no need to panic. Plants can operate until the end of their useful lifetimes, and substitute refrigerants will very certainly be discovered.

R407C Refrigerant: An Overview

Al Imran provides all of the primary types of refrigerants used in bus HVAC systems (R134a and R407C) and chooses the refrigerant dependent on the application. We recommend R407C for all-electric applications because it gives the most efficient outcomes, especially in hermetically sealed systems.

Since R407C operates at a greater pressure than R134a, it has a higher Coefficient of Performance in securely sealed systems. HVAC equipment is intended to perform efficiently with higher pressure refrigerants and has done so for more than ten years with R407C.


The Cost of R407C

The cost of R134a vs R407C is equivalent, with no major cost difference between the two. To preserve optimal operational efficiency. Refrigerant distribution units containing R407C can have refrigerant injected in the event of a leak.

To demonstrate this point, the refrigerant suppliers, WESTRON , allowed a system to leak 50% of its charge in vapor form before simply topping it off. They repeated this operation five times, which is an extreme circumstance, but after the fifth recharge, the system was evaluated and found to have lost just around 9% of its initial capacity.

Environmental Impact of R407C

It possesses thermos physical characteristics that are quite comparable to those of R-22. If you decide to go from R-22 to R407C, your refrigeration system should only require minor modifications. If you’ve been using R-22 for a while, you’ll notice that the components used in R-22 and R407C are nearly identical.

As the qualities and performance demonstrated, it is less hazardous to the environment than R22. R407C has the same global warming potential as R-22, but it has zero ozone depletion potential, which is one of the most critical considerations.
