The actual press release is pretty long so I won't copy it, but there's a blurb that says this:
The U.S. Department of Energy (DOE) today announced the publication of a report that summarizes the results of the DOE-funded testing program to evaluate the performance of alternatives to HFCs in mini-split air conditioning units in high ambient temperatures. The testing program was conducted at Oak Ridge National Laboratory (ORNL), and guided by a panel of international technical experts from Brazil, China, Egypt, India, Italy, Japan, Peru, Saudi Arabia, and the U.S. The panel also included representatives from the United Nations Environment Programme (UNEP) and the United Nations Industrial Development Organization (UNIDO). The testing program was launched in response to concerns that some stakeholders have raised about whether alternatives to HFCs can perform well in high ambient temperatures, and the results show that several viable replacements exist for both HCFC-22 and HFC-410A in those environments for mini-split air conditioning units. The report can be found at:
I may or may not know someone involved in that research... it's no invitation the White House (that's my dream, lol), but it's pretty cool to be part of a White House press release, however dorky.
