Four of the five winning projects in the ASHRAE-UNEP 2019 Innovation Awards – designed for developing countries – involve natural refrigerants. National Ozone Unit representatives from the winning regions accept certificates on behalf of the selected projects at an ASHRAE-UNEP side event held during MOP31. ASHRAE and the UN Environment Programme (UNEP) yesterday announced the project selections for the 2019 OzonAction Lower-GWP Refrigeration and Air-Conditioning Innovation Awards. Out of the five winning projects, four included natural refrigerants.  The projects were recognized at an ASHRAE UNEP side event held during the 31st Meeting of the Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer (MOP31) in Rome.   This annual international award program promotes innovative design, research and practice by recognizing people who have developed or implemented innovative technological concepts applied in developing countries to promote lower GWP refrigerants through refrigeration and air-conditioning applications. “The projects selected represent long-term, global and energy efficient solutions to lessen the impact of ozone depleting substances,” said Sheila J...
