China R1234yf Refrigerant for Mobile Air Conditioner

R-1234yf
( HFO-1234yf)
HFO-1234yf, is a new more environmentally sustainable refrigerant for automobiles that has a 99.7% better GWP score than the currently used refrigerant.
CAS NO.:754-12-1

Replace
R134a

Applications
Refrigerants. Low GWP. Substitute for R134a in automobile air conditioner.
MAC, bus&train a/c, small stationary
Benifits
HFO-1234yf will make an important contribution to a reduced environmental footprint for automobiles. If adopted in all new cars sold in the EU, North America, and Japan, every year those cars would have reduced emissions equivalent to using 2.3 to 4.9 billion fewer liters of fuel or driving 24 to 52 billion fewer kilometers. (This is equivalent to using 600 million to 1.3 billion fewer gallons of fuel or driving 15 to 32 billion fewer miles.)
When comparing HFO-1234yf and CO2 as an automotive refrigerant, HFO-1234yf has very distinct benefits with regard to fuel efficiency and overall sustainability. CO2 would require a much larger, heavier air conditioning system than what is used in most cars today, which is contrary to the trend toward smaller, more fuel-efficient, sustainable cars. Lifecycle climate performance evaluations have also concluded that CO2 is not as efficient as HFO-1234yf in warmer climates, and would therefore contribute considerably more overall to total greenhouse gas emissions, and even more so as the projected vehicle sales volume in warmer, developing countries such as India and China continues to increase.

Notes:
Starting in January 2011, all new vehicle types must have an air conditioning refrigerant with a global warming potential (GWP) below 150. From 2017 on, this will apply to all new vehicles. This is based on the MAC Directive (2006/40/EG), passed in July 2006.
