A new Daikin refrigerant announced last year as a more efficient alternative to R1234yf in electric vehicles has been designated as R474A by ASHRAE and given an A2L classification.

More than 60% of German electric buses (e-buses) in 2021 used Konvekta’s CO₂ (R744) heat pump systems, according to a recent statement from the German manufacturer.

The global HVAC-R market was valued at $193.6 billion in 2021 and is projected to reach $257.9 billion in 2027, following a CAGR of 5% during the forecast period 2022-2027. The growth in the global HVAC-R market is expected to be driven by increasing population and rapid urbanization, drastic change in weather conditions, and emerging innovation in HVAC-R.

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.

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.

SIAD, an Italian provider of gases, has for the first time publicly presented its COOOL FreeToGo compressor-free refrigeration transport system, which uses liquid CO₂ (R744) evaporation to generate cooling without the traditional vapor-compression cycle.

German OEM TEKO has entered a new market with its CO₂ (R744) cooling technology, introducing a unit called ROXSTAtrain for kitchens on trains, and other applications with very limited space.

GEA has had further marine success with its CO₂ refrigeration systems onboard an Alaskan fishing trawler.

Panasonic’s CO₂ condensing unit is contributing to an innovative mobile refrigeration test trailer for a pioneering UK contractor.

Following the first installation of transcritical CO₂ refrigeration technology on board a cruise ship last year, German manufacturer GEA says it has received orders for two new ships.

The Nordic Council of Ministers has recommended that the marine shipping industry convert its refrigeration systems to “natural” refrigerants.

The Trump administration is reported to be planning to restore compliance credits for US automakers that could encourage greater use of low GWP refrigerant R1234yf in car ac systems.

At the 2018 International Motor Show (IAA) in Hannover, Germany (20-27 September 2018), Eberspaecher Suetrak is showcasing its CO₂ mobile air conditioning (MAC) system for buses.

Global shipping company MSC Mediterranean Shipping is to lease 2,000 containers using Carrier Transicold’s NaturaLINE CO₂ refrigeration system.

GEA has installed a CO₂ refrigeration system on the P&O cruise ship Arcadia, with discussions ongoing to introduce the technology throughout P&O’s fleet.

Initial results show that energy savings of 33% have been achieved by the new Trane CenTraVac chillers using the HFO 1233zd(E) to cool the Channel Tunnel link between the UK and France.

Early bird registration is now open for the 2018 EuroventSummit, the Eurovent association’s major gathering for key decision-makers in HVAC, process cooling, and cold chain technologies.

New air conditioning efficiency standards are needed if the world is to avoid an energy “cold crunch” from the growth in cooling demand in coming decades.

Refrigerant supplier and reclaimer A-Gas has expanded its European influence with the acquisition of German company Arthur Friedrichs Kaeltemittel GmbH.
