Mark McLinden, of MML's Applied Chemicals and Materials Division, was awarded the rank of Fellow in the American Society of Heating, Refrigerating and Air-Conditioning Engineers. The presentation was made at the Winter Meeting of ASHRAE January 20 in Chicago. The rank of fellow is awarded for "substantial contributions and distinction in HVAC&R and the built environment;" only about 1 % of ASHRAE members hold this rank. In particular, McLinden was noted as a coauthor of every release of the NIST REFPROP database, which is the industry standard for refrigerant properties; the measurement of refrigerant thermodynamic properties at high accuracy; and the examination of the "universe of molecules" to identity refrigerants with low global warming potential.
