Introduction:
R1234yf is a colorless HFO refrigerant gas also called 2,3,3,3-Tetrafluoropropylene.
It is called the future of refrigerant gas because of having an extremely lower greenhouse gas damaging effect.
Its GWP rating is around one or less than that. R-1234yt or HFO-1234yf refrigerant is a hydro gen, fluorine, and carbon structure with one double tie of carbon atoms.
This synthetic HFO-1234yf refrigerant gas has nearly the same physical and thermal properties value as R134a refrigerant except for minor differences.
Specification:
| Name | 2,3,3,3-Tetrafluoropropylene |
| Model | R1234yf/HFO-1234yf/R-1234yf |
| Classification | Hydrofluroolefin |
| Formula | CF3CF=CH2 |
| Cas No. | 754-12-1 |
| Replacement for | R134A,R12 |
Application:
The new R1234yf refrigerant is designed as a choice for R134a. It has an A2L mild flammability rating.
This non-toxic refrigerant gas is very environmentally friendly. R-1234yf refrigerant has high efficient heat removal characteristics more than R134a.
As R134a refrigerant gas wasn’t designed for flammable refrigerant, the HFO-1234yf is a perfect choice.
R-134a refrigerant was a popular alternative for R-22, but because of its extremely high GWP R134a, it will be banned soon, and the new alternative is R1234yt refrigerant.
Though it is comparatively new, HFO-1234yf has no dangerous substance that damages greenhouse gas and has lower than 1 GWP, while R134a had 1300 GWP.
But HFO -1234yf has similar properties to R134a, and both use SAE J2842 evaporator.
