R1234yf will replace R134a to become the main alternative auPosition:Home > Blog
Since January 1, 2017, all new cars produced and marketed in the European territory, prohibit the use of GWP> 150 refrigerants. As can be seen widely as automotive air conditioning refrigerant R134a (GWP = 1300) of the phase-out will become an inevitable trend. DuPont and Honeywell introduced the fourth generation of refrigerants R1234yf and R1234ze be considered an alternative to a new generation of environmentally friendly refrigerant R134a, so R1234yf will first be applied to car air conditioning on.

Air conditioning and refrigeration market experts: Since no chlorine atom in the molecule, HFO1234yf of ODP is zero; because HFO1234yf life span of only 11 days in the atmosphere, GWP of 4, and the atmosphere and HFO134a same decomposition products, the impact of climate environment HFO1234yf almost negligible, far less than the HFC134a. Security HFO1234yf no flash point, ignition point 405 ?, weak flammability, HFO1234yf flammability known to be far less than several flammable refrigerant, HFO1234yf low toxicity of the chemicals, which belongs to ASHRAE toxicity classification of A level, but when inhaled can cause drowsiness and lack of concentration, dizziness, eye, skin and respiratory system irritation.

After several years of rigorous testing, HFO1234yf has been the United States, Europe, Japan and South Korea approved a number of car manufacturers, and has begun commercial preparation.
