Past IoR President and regular ASHRAE Journal columnist Andy Pearson of Star Refrigeration provides the background to refrigerant choices with a brief overview of ozone and climate change issues and comment on the practical implications of this shift for system designers owners and operators.
He reflects on European f-gas regulation development and its implications and the UNEP efforts to restrict HFCs under the Montreal and Kyoto protocols. He specifically considers the effect of the very recent Kigali agreement that aims to significantly reduce the worldwide use of HFCs being that HFC gases are thousands of times more destructive to the climate than carbon dioxide as well as the potential effects of Brexit - on regulations, on European standards and others.
He discusses the likely consequences on the future choices for refrigerants in building systems in light of the recent shifts in the political landscape on both sides of the Atlantic.
Andy is a past President of the Institute of Refrigeration and has served two terms as a director of the International Institute of Ammonia Refrigeration and is a member of the Refrigeration Safety Technical Committees for the British Standards Institute (BSI), the European Committee for Standardisation (CEN) and the International Standards Organisation (ISO) and is Chapter Lead Author for United Nations Environment Programme Refrigeration Technical Options Committee. His principal interests are in the design of more efficient refrigeration systems and troubleshooting of faulty, inefficient or unreliable equipment.
He is Fellow of Institute of Refrigeration, Fellow of Institution of Mechanical Engineers, Fellow of ASHRAE, Fellow of Institution of Engineers and Shipbuilders in Scotland and a Chartered Engineer
