What is R 1234ze?
R1234ze is a low Global Warming Potential (GWP) refrigerant, used as a replacement for R134a in medium temperature refrigeration and air conditioning applications including water chillers.
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.
Is R 1234ze an HFO?
R-1234ze belongs to a new family of HFOs (hydro-fluoro-olefins) that have a low GWP. R-1234ze can be used in air conditiong chillers, heat pumps, and some other R-134a applications.
What is the ASHRAE classification of R410A?
R-410A, the most common air conditioning refrigerant in use globally today, is not actually “non- flammable.” It is ASHRAE-listed as an A1 refrigerant, meaning that it has no flame propagation at 63°C. Toxicity is classified based on Occupational Exposure Limit (OEL).
Is R134a phased out?
On September 26, 2016, the EPA announced that, under the EPA SNAP (Significant New Alternatives Policy) program, specific refrigerants including R134a and R410A can no longer be used in new chillers, effective January 1, 2024.
Is R1234ze and A2L?
ASHRAE Standard 34: 2010 designates refrigerants according to their flammability. The most viable low GWP refrigerant alternatives to R410A and R134a, like R32 and R1234ze, are all A2L.
What is the molar mass of HFO 1234ze?
114.04 g/mol
The molecular formula C3H2F4 (molar mass: 114.04 g/mol) may refer to: 1,3,3,3-Tetrafluoropropene (HFO-1234ze)
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 ASHRAE number?
ASHRAE assigns numbers and safety classification to the refrigerants based on toxicity and flammability data submitted by the refrigerant’s producer. For blends, numbers are assigned sequentially based on the completion of a satisfactory review of data provided by the refrigerant’s producer.
What does ASHRAE mean?
using its full legal name of the American Society of Heating, Refrigerating and Air-Conditioning Engineers. Use of ASHRAE reflects the Society’s worldwide membership and that services will continue evolving globally.
