EPA Approves New Low-GWP Refrigerants

Posted March 11, 2015 1:00 AM by larhere

On March 3, the Environmental Protection Agency (EPA) released a pre-publication Federal Register notice adopting new low-global warming potential (GWP) refrigerants under the Significant New Alternative Policy (SNAP) program. The final rule adopts the following refrigerants, subject to use conditions:

  • R-32 in room air conditioning units.
  • Isobutane in retail food refrigeration (e.g., stand-alone commercial refrigerators and freezers) and in vending machines;
  • Propane in household refrigerators, freezers, combination refrigerators and freezers, vending machines, and room air conditioning units;
  • R-441A in retail food refrigeration (e.g., stand-alone commercial refrigerators and freezers), vending machines and room air conditioning units; and
  • Ethane in very low temperature refrigeration and in non-mechanical heat transfer;

According to the EPA's definition, room air conditioning units include packaged terminal air conditioners and heat pumps, window air conditioners, and portable air conditioners designed for use in a single room.

Specifically excluded from the definition are central air conditioners, and mini-split and multi-split air conditioners and heat pumps.

Finally, with the exception of R-32, the EPA is exempting all the above listed refrigerants from the non-venting provision of the Clean Air Act.

There is " No " man made climate change, and the actual trend that is being seen is cooling, not warming.

Global Warming is a BIG politically driven lie based on fraudulent pseudo-science. Flammable Hydrocarbon refrigerants are a REAL BAD idea, along with all refrigerants that use Polyester oil. Whats going on with this entire scenario is a massive, political and ego driven mind control operation that has got 99% of people involved buying into it. R-32 is a component of former, " very effective " refrigerants. The EPA is in reality the environmental destruction agency. They are in the large creating far more problems than they are solving as is always the case with this kind of out of control "bureaucracy." All of this is driven by materialist reductionism which is a " Priest class." Its all rooted in falsehoods that are not and cannot be proven.
