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.

Tested A2L refrigerants are difficult to ignite and had low flame speeds.

Important air quality information for employers and workers.

Since the Rees Scholarship Foundation was founded in 2003, it has awarded more than $1 million in scholarships to 643 deserving students and instructors.

AHRI-led program simulates real-life conditions in order to develop data and insights into the risks associated with the use of flammable refrigerants.

The ASHRAE Winter Virtual Conference will be held Feb. 9-11.

The campaign, which builds on an AHRI White Paper, Anatomy of a Healthy School, is designed to help building engineers maintain and design school buildings for occupancy in the wake of the COVID-19 pandemic.

The amendment is a bipartisan compromise based on the American Innovation and Manufacturing Act (S. 2754), a bipartisan bill introduced last year by Sens. Kennedy and Carper that would boost American manufacturing of next-generation refrigerant technologies, promote American innovation, and create tens of thousands of new domestic manufacturing jobs.
