Natural refrigerants deserve to be a bigger part of the climate-saving solution. CO2 has the potential to be as common of a refrigerant as R404A is today, at least for industrial process refrigeration systems.

Absorption chillers offer distinct, and sometimes surprising, advantages for industrial cooling applications. To truly evaluate the cost-effectiveness of an absorption chiller, it is critical to take into account how COPs correspond with actual energy costs.

A range of microchannel heat exchangers has been optimized for use with low density, low global warming potential (GWP) refrigerants like R-1234ze and R-515B.

Three ice rinks in China will utilize lower global warming potential (GWP) refrigerants as they prepare to host hockey and curling games at the 2022 Olympic and Paralympic Winter Games.

Cimco Refrigeration, a Canadian industrial refrigeration contractor who also serves the recreational refrigeration market, will no longer manufacture recreational ice-rink packages that use high GWP refrigerants, including HFO blends such as R513a.

Starting in June 2017, Real Alternatives 4 Life, led by eight project partners, aimed to develop training materials, practical exercises and assessments to standardize the skills set and requirements for handling low GWP refrigerants globally.

As of January 1, Chemours Co. suspended supply of high GWP refrigerants R-404A (GWP 3922) and R-507A (GWP 3985) in the European Union. The decision was made to support the market transition driven by the European Union F-Gas regulation to lower GWP alternatives and prepare for the next quota phasedown in 2021.

Carrier Transicold Europe, located in Rueil-Malmaison, France, will collaborate with Chemours to specify and adopt an Opteon XL low global warming potential (GWP) hydrofluoroolefin (HFO) refrigerant to replace R-452A in transport refrigeration in 2021.

The York YZ magnetic bearing centrifugal chiller won the 2019 AHR Expo Innovation Award in the Cooling category. Manufactured by Johnson Controls, the fully-optimized chiller is built with low-global warming potential (GWP) refrigerant to increase energy efficiency.

Opteon XL41 (R-454B) refrigerant, a low global warming potential (GWP) replacement for R-410A, was selected by Johnson Controls for its York YLAA scroll chiller platform in Europe. Reasons cited for the selection include Opteon XL41’s capacity ranging of 190 to 530 kW.
