R1234yf

This colorless gas has been proposed as a replacement for R-134a as a refrigerant in automobile air conditioners. It thus significantly reduces the carbon footprint of refrigeration systems over the total lifetime. Due to environmental concerns, refrigerants with a low global warming impact are gaining importance in the refrigeration industry.

That same year, General Motors (GM) began using it in the Cadillac XTS. Experiments were conducted for a typical R134a compact European automotive air conditioning system equipped with an internally controlled variable displacement compressor, minichannel condenser, TXV, and minichannel evaporator.

There has been a lot of hype about the changeover to this refrigerant. Instea it will be a slow adoption the next three to five years. R134a will not be phased out, but it will be regulated and taxed heavily. Test your knowledge and earn certificates. Training by Honeywell and AVI OnDemand.
