What is R1234yf GWP?

HFO R1234yf has a GWP of just 4, providing substantially lower direct greenhouse gas emissions than R134a systems. It thus significantly reduces the carbon footprint of refrigeration systems over the total lifetime.

How flammable is R1234yf?

R1234yf is classified as A2L mildly flammable. Technicians need to take the relevant safety measures for the correct transport, storage and handling of a flammable gas. This would include, but is not limited to, ensuring no open flames (including smoking) near the system.

Who manufactures 1234yf?

USA: Honeywell has today started commercial production of the refrigerant R1234yf at its new manufacturing plant in Geismar, Louisiana.

What does HFO-1234yf stand for?

hydrofluoroolefin
2,3,3,3-Tetrafluoropropene, HFO-1234yf, is a hydrofluoroolefin (HFO) with the formula CH2=CFCF3. It is also designated R-1234yf as the first of a new class of refrigerants: it is marketed under the name Opteon YF by Chemours and as Solstice YF by Honeywell.

What refrigerant has a GWP of 1?

Carbon dioxide
Carbon dioxide was chosen by the Intergovernmental Panel on Climate Change (IPCC) as the reference gas and its GWP is taken as 1.

What is SAE Standard J639?

HFC-134a (Relevant SAE Standard: J639) HFC-134a is the most common MVAC refrigerant used since the 1990s. Although HFC-134a does not deplete the ozone layer, it is a potent greenhouse gas with a high global warming potential.

Is R134a refrigerant explosive?

Under normal conditions, R134a is a non-flammable gas but exhibits an explosion range at higher oxygen percentages than those in air. At increased temperatures or pressures, R134a also has an explosion range in air, i.e. without any higher oxygen percentage.

Why did they switch to R1234yf?

The auto industry has transitioned some U.S. models to R-1234yf, although it’s not required by current U.S. law. The reason the auto industry is transitioning its U.S. models is to achieve commonality with European models, and to gain Corporate Average Fuel Economy (CAFE) “credits” from the EPA.

What oil is used with 1234YF?

PAG oil YF is suitable for both R1234yf and R134a refrigerants. PAG SP-A2 oil for refrigerants R1234yf and R134a For use in electric air conditioning compressors, such as those manufactured by SANDEN and VISTEON (Hanon).

What happens if you put 134a in a 1234yf system?

If you were to put R1234yf in a system designed for R134a, it looks like you’d end up with about a 10% loss of cooling capacity, but putting R134a into a R1234yf system would be a wash. It appears R1234yf oil is compatible with R134a (but not vice-versa), so shouldn’t be a problem there.

Is R134a a GWP?

The aim of this paper is to present the main operating and performance differences between R513A (GWP of 573) and R134a (GWP of 1300), the most used refrigerants for medium evaporation temperature refrigeration systems and mobile air conditioners.
