Sorry GWP of 1 instead of 7.
The GWP of HFO-1234ze is not 7 but .
Reference : http://www.fluorocarbons.org/chemical-families/hfos quoring the IPCC 5th Assessment Report.
It is strange that Carrier is still using an outdated value.
Does somebody know which refrigerant will be used for cooling ?
What about this info in this case ?
CO2 confirmed as refrigerant in Sainsbury's leak
All chemicals can burn, depending on the conditions, and R134a was found to be explosive at high temperature and pressure.
"There is however, the potential, through large scale accidental leakage for explosions to occur. This happened in Germany in 1994 at a Hoechst production facility for HFC-134a (8).
Before this event HFC-134a had been considered safe and completely
inflammable in normal circumstances. Carbon containing gas mixtures should
never be considered completely inflammable; the potential for explosive mixtures to be spark ignited should not be overlooked. "
