R-1234yf Refrigerant

R-1234yf is a low-global-warming-potential mobile air conditioning refrigerant.

It is used in many vehicles for environment protection & satisfaction of regulations.

HFO-1234yf is a highly-efficient, safe and effective replacement for HFC-134a, is already in use by the auto industry. It has a LOW Global Warming Potential (GWP) and NO Ozone Depletion Potential (ODP), both of which contribute to climate change. 

Most US major automakers have adopted R-1234yf in several or all of their models, with nearly 70% of  2019 vehicles using R-1234yf air conditioning systems. It is already the standard for all vehicles in Europe.

Excellent environmental properties

  • Very low GWP of 4, Zero ODP, Favorable LCCP
  • Atmospheric chemistry determined and published

Low toxicity, similar to R-134a

  • Low acute and chronic toxicity
  • Significant testing completed

System performance very similar to R-134a

  • Excellent COP and Capacity, no glide
  • From both internal tests and OEM tests
  • Thermally stable and compatible with R-134a components
  • Potential for direct substitution of R-134a

Mild flammability (manageable)

  • Flammability properties significantly better than 152a; (MIE, burning velocity, etc)
  • Potential for “A2L”ISO 817 classification versus “A2”for 152a based on AIST data
  • Potential to use in a direct expansion A/C system -better performance, lower weight, smaller size than a secondary loop system

The evolution of A/C Refrigerants:

A/C Refrigerants Global Warming Potential (GWP) Ozone Depletion Potential (ODP)
R-12 high high
R-134a high none
R-1234yf low none
