Japanese OEM Nihon Netsugen System (NNS), a pioneer in CO₂ (R744) refrigeration in Japan, exhibited its SUPER GREEN, an industrial CO₂ refrigeration system.

Refrigerants market is expected to reach at USD 8.4 billion in 2027 at a CAGR of 6.2% during the forecast period. The most used natural refrigerants are ammonia, carbon dioxide, and HCs such as propane and isobutene. Technological advancements in cooling equipment are replacing traditional refrigerants such as HCFC and HFC with natural ones. This has increased the market share of natural refrigerants in applications such as air conditioning, refrigeration, and heating systems.

The cold chain must be sustainable everywhere to be able to meet the Millennium’s targets indeed.

Integrating a building glycol loop to a supermarket transcritical CO₂ (R744) system in Canada yielded “superior” results, according to Phillip Walker, Arneg’s Director of Refrigeration Solutions, who spoke during the ATMOsphere America 2022 conference on June 7–8.

Austrian manufacturer AHT, part of Daikin, highlighted its propane (R290)-based cabinets and Active Monitoring System (AMS) as part of World Refrigeration Day, celebrated yesterday (June 26) under the theme “Cooling Matters.”

Trane®, global provider of indoor comfort solutions and services and a brand of Trane Technologies, announced today it is expanding its Sintesis™ Balance CMAF portfolio of multi-pipe units for simultaneous cooling and heating. The new models are now available with R-454B refrigerant in capacities ranging from 150 to 1,400 kilowatts (kW). The units deliver better cooling and heating efficiencies, improved operating maps and lower environmental impact compared to equivalent models with R-410A.
