What is the GWP of R 1234ze?

(7)
The R1234ze refrigerant is a HFO refrigerant with a very low GWP (7). For this reason it is one of the most relevant options to ensure low impact on the environment and compliance with regulation.

What is HFO 1234ze gas?

1,3,3,3-Tetrafluoropropene (HFO-1234ze(E), R-1234ze) is a hydrofluoroolefin. It was developed as a “fourth generation” refrigerant to replace fluids such as R-134a, as a blowing agent for foam and aerosol applications, and in air horns and gas dusters.

What is the GWP of refrigerants?

The most common refrigerant today, R-22, has a 100-year GWP of 1,810, almost 2,000 times the potency of carbon dioxide, so just one pound of R-22 is nearly as potent as a ton of carbon dioxide.

Is HFO 1234ze a greenhouse gas?

The HFOs 1234yf, 1234ze and 1233zd are amongst a number of fluorinated greenhouse gases and fluorinated heat transfer fluids being added to the Environmental Protection Agency’s Greenhouse Gas Reporting Rule.

What is the GWP of r410a?

R-410A has an ODP of zero and a GWP of 2,088. Both R-32 and R-125 are HFCs and have ODPs of zero because their molecules do not contain chlorine. R-32 has a low GWP of 675, which is favorable when transitioning to lower GWP refrigerants.

What are HFO refrigerants?

HFOs (hydrofluoro-olefins) are the fourth generation of fluorine-based gases. HFC refrigerants are composed of hydrogen, fluorine and carbon atoms connected by single bonds between the atoms.

What is the GWP of R513A?

573
R513A is a blend composed by R134a/R1234yf at 44/56 mass (percentage) with a GWP value of 573 and it is a non-toxic and non-flammable fluid.

Is 1234ze flammable?

Hydrofluoroolefin 1234ze (1,3,3,3-Tetrafluoropropene) is a fluorinated hydrocarbon introduced as a low global warming potential alternative for HFC-134a (1,1,1,2-tetrafluoroethane) and is classified as mildly flammable (A2L).

What is HFO refrigerant?

What refrigerant has lowest GWP?

R-717
According to the California Air Resources Board, that would be R-717, which has a 100-year GWP of 0. R-717 goes by the trade name Ammonia, which has been around since the 1930s. Experts today recognize it as the most efficient refrigerant in the world.

What type of refrigerant is HFO?

unsaturated HFC refrigerants
HFO refrigerants are actually unsaturated HFC refrigerants and are widely recognized as the next generation of refrigerants because of their environmental friendliness, cost-effectiveness, and great energy efficiencies. HFOs are distinguished from HFCs by being derivatives of olefins rather than alkanes (paraffins).

What is the GWP of HFC?

Both HCFC-22 and HFC-134a are potent greenhouse gases, with global warming potentials (GWPs) of 1,760 and 1,300 on a 100-y time scale (2).
