Carrier has adopted the Chemours refrigerant R454B as its primary lower GWP replacement for R410A in ducted residential and light commercial air conditioners sold in North America.

Chinese air conditioning manufacturer Midea is to use R452B, a lower GWP alternative to R410A, in its unitary air conditioning units designed for the North American market.

Refrigerant manufacturer Chemours has broken ground on a new R1234yf production facility at its Corpus Christi plant in Ingleside, Texas.

The Oak Ridge National Laboratory High-Ambient-Temperature Evaluation Program for Low Global Warming Potential (Low-GWP) Refrigerants project was aimed to develop an understanding of the performance of low-GWP alternative refrigerants to hydrochlorofluorocarbon (HCFC) and hydrofluorocarbon (HFC) refrigerants in mini-split air conditioners under high-ambient-temperature conditions. This final report describes the parties involved, the alternative refrigerant selection process, the test procedures, and the final results.

The viability of new lower GWP alternative refrigerants in high ambients are said to have been proven in new tests.

A US manufacturer exhibited a ductless air-cooled water chiller using Opteon XL55, a lower GWP replacement for R410A, at the 2016 AHR Expo which opened on 25 January 2016.

HFO-1336mzz(Z) is to be promoted as a potential working fluid for high temperature heat pumps at this week’s ICR 2015 conference in Japan.
