The HVACR industry is unique in that it is made up of professionals from many different sectors. And while we all ultimately address the same goals, the everyday disciplines and practices often look very different. It is with this in mind that the AHR Expo, in conjunction with ASHRAE; Air-Conditioning, Heating, and Refrigeration Institute (AHRI); and several other organizations, created the Industry Trend Report in 2020 to provide a thoughtful connection point for HVACR audiences.
John Galyen, president of Danfoss in North America, discusses his tenure as chairman of Air-Conditioning, Heating & Refrigeration Institute (AHRI); the factors driving Danfoss’s success; and the future of the HVACR industry as a whole.
In addition to the standard T1 test conditions (35°C outdoor dry-bulb), AHRI has been introducing the T3 test conditions (46°C outdoor dry-bulb) and T4-Kuwait (48°C) with operability tests at 52°C for a large range of “tropical” air conditioning products in the high ambient temperature (HAT) countries of the Gulf Cooperation Council (GCC).
For new residential and light commercial central air conditioning equipment, the AHRI petition seeks a regulation requiring that equipment manufacturers use refrigerants with a global warming potential (GWP) of 750 or less in equipment made after Jan. 1, 2025, with the exception of variable refrigerant flow (VRF) equipment, whose deadline would be Jan. 1, 2026.
