So issue, both in terms of running leakage of 1 kg of R404A is two costs and energy-related CO2 to three times worse in terms emissions. The choice of of global warming impact than refrigerant has an effct on some other HFC refrigerants. energy efficiency and R404A is It is worth noting that, a poor choice.
Is R404a bad for the environment?
The ODP and GWP values of R404A exceed the standard, which has extremely adverse effects on the environment. R-449A is a refrigerant that is fully environmentally friendly.
What is the most environmentally friendly refrigerant?
The most environmentally friendly refrigerants are hydrofluorocarbons (HFC) and hydrofluoro-olefins (HFO). HFCs are comprised of fluorinated hydrocarbons. While HFCs can contribute to global warming, they do not affect the ozone layer directly.
Is R404a ozone depleting?
Although R-404A consists of a mixture of three HFC refrigerants and has an ozone depletion potential (ODP) of zero, it does have a GWP of 3,922, according to the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report, 2007.
Why is R404a being phased out?
R404a has the highest carbon dioxide rating of all refrigerants on the market, meaning the shift to a lower GWP refrigerant is imminent. A transfer to lower GWP products cannot wait until 2020 as it is necessary to move as soon as possible. This is because R404a will not be available to buy for virgin use.
What refrigerant will replace R404A?
For cold rooms and other small to medium commercial refrigeration applications, R448A and R449A and R452A or R134a are excellent alternatives to R404A, with from 50 to 65% reduction in GWP. R513A, newer alternative, is also very appropriate in medium back pressure (MBP) applications.
What class refrigerant is R404A?
R404A is a non-toxic, non-flammable, Class 2.2 product meeting the highest ASHRAE standard A1/A1 classification. R404A has an Ozone Depletion potential of 0, a Global Warming Potential of 3260.
Which refrigerant is not eco-friendly?
They are used in making aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants. Due to their high ODP (Ozone Depletion Potential) and high GWP (Global Warming Potential), they are considered non-eco-friendly refrigerant gases.
Which AC gas is eco-friendly?
The most environment-friendly refrigerants that are available in Indian market currently are “R-290” and “R-600A”.
|Refrigerant||Global Warming Potential||Ozone Depletion Potential|

Is R404a toxic?
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.
Is 404A a low temp refrigerant?
R404A is a zeotropic HFC refrigerant blend of R125, R143a and R134a. It is widely used in medium and low temperature refrigeration especially in the supermarket sector and for refrigerated transport.
Is 404A refrigerant being phased out?
All new cooling and refrigeration systems that support R-404a will no longer be available from 1st January 2020. Therefore throughout 2018 and 2019, the refrigeration systems running on R-404a will need to be replaced or support a retrofit alternative refrigerant.
Can R404A still be used?
While virgin R404A can no longer be used in new equipment, recovered or reclaimed R404A can be used until the end of 2030. After that point, all replacement R404A will be banned.
What is R404A refrigerant used for?
R-404A:Refrigerant for packaged air conditioners, commercial air-conditioning and vending machines. R-404A:Refrigerant for showcases, vehicle-mounted refrigerators, and commercial freezers.
What is the difference between r134a and R404A?
R134 is designed for what is called high/medium temp jobs such as chillers R404 is for lower temp work ie freezers. If its for “middle east trucks” then look to see what the supply is for these gases in the middle east and what units you fit to what is recommended by manufacturer.
