German manufacturer Viessmann Group has announced that it plans to open a new production site in Legnica, Poland, for its largest business area, Climate Solutions, with a particular focus on high-efficiency, propane (R290)-based heat pumps.

Israeli heat-exchanger manufacturer Lordan Coils has developed a cold-climate propane (R290) residential heat-pump water heater (HPWH), using 5mm (0.2in) MicroGroove copper tubes to achieve a low charge.

An ammonia heat pump from German manufacturer GEA is being used in a project using the water in an abandoned coal mine to supply a 6MW district heating network.

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.

OEM Kysor Warren Epta US has announced that it expects to bring its new CO₂ (R744)-based condensing unit to the U.S. market by the end of 2022, according to a recent presentation by the company’s Sustainability and New Technologies Manager, Ignacio Chaparro.

Konvekta, a German manufacturer of CO₂ (R744) heat pump systems for commercial vehicles, has developed a new software module – “Additional Energy Storage (AES) Mode” – that eliminates the need for an electric heater in electric buses, reducing both costs and energy consumption.

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.

Cimco Refrigeration, a Toronto-based industrial refrigeration contractor, has reduced energy consumption at a Quebec-based meat-processing plant operated by Viandes Paquette by 2.5 million kWh annually with a low-charge ammonia/NH₃ (R717) system. By reclaiming excess heat from the ammonia system, Cimco removed the need for any boilers at the plant.

German manufacturer Gea Heating & Refrigeration Technologies is expanding its ammonia product portfolio, adding two screw CompaX compressors and a brand-new Grasso X semi-hermetic screw compressor package.

The Centre for Energy Technology (ZET) at the University of Bayreuth has handed over a CO₂-powered air conditioning system to the Kulmbach Vocational School Centre (BSZ) for use in its operations and teaching.

The World Refrigeration Day (WRD) and the U.K.-based Stemazing campaign have joined forces to launch the International WRD Stemazing Inspiration Academy, in which women from the HVAC&R industry will teach children STEM (science, technology, engineering and math) disciplines.
