The ‘R’ in Refrigeration Service Engineers Society (RSES) got its due at the 76th RSES Annual Conference and HVACR Technology Expo in Pittsburgh, Pa. Topics ranged from the latest trends in refrigerants to the servicing of equipment, from basic components to complex systems using such refrigerants. Training was available for beginners and professionals.
In his keynote speech, Robert Wilkins, vice president of public affairs, Danfoss, said, “Change is coming. Refrigerants are the largest single issue with a global perspective.” He called on contractors and technicians to become involved in developments because it would be better to solve a problem before it reaches the critical phase. He specifically referenced efforts globally to move from primary use of hydrofluorocarbons (HFCs) to use of carbon dioxide and hydrocarbons (HCs). He said current proposals to phase down production of HFCs within the context of the Montreal Protocol are not imminent but may come in two to three more years with a few more years to negotiate adaptations in various countries.
