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.
U.S.-based supermarket chain Hannaford has equipped the entire frozen section of its new store in Brunswick, Maine, with propane (R290) self-contained cases, according to a recent presentation by Harrison Horning, Director of Maintenance, Retail Business Services – Hannaford and Stop & Shop, part of Ahold Delhaize.
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.
We are all aware of the F-Gas legislation and the drive to low GWP refrigerants but this is only a small part of the overall solution to reduce climate changing emissions. Choosing a low GWP refrigerant does not guarantee a better energy efficiency and in some cases, it may even lead to an increase in the lifetime total emissions from the system if a lower efficiency option is selected. As well as refrigerant choice, there are other actions that can be taken to maintain or improve energy efficiency, reduce total emissions and in most cases they will even pay for themselves over the lifetime of the equipment.
Supermarket giant releases findings from store trial looking at energy efficiency impacts of switching from older CO2 solution to a lower flammability A2L system.
The F-gas regulation is continuously progressing with two new bans having come into effect from 1st January 2022 but most of the implications of the legislation are still hidden by the apparent abundant supply of higher GWP refrigerants.
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.
At the meeting in December of the American Geophysical Union (AGU), glaciologists released some alarming observations: the Antarctic Thwaites glacier is torn by cracks and risks of crumbling completely at time intervals estimated from 5 to 10 years. The news is alarming because this glacier – more or less, as big as Florida – contains enough water to raise sea levels around the world by about half a meter. Already today, the melting of the glacier contributes to 4% of the current annual rise in sea level. Not fortuitously, this glacier is also called “Doomsday glacier”.
A COVID-19 vaccine storage warehouse, opened in Spain last year, selected a PowerCO2OL CO2 (R744) refrigeration rack from OEM Carrier Commercial Refrigeration for its cooling needs.
In the light of the worldwide phase-down of high GWP refrigerants, Dave Richards, UK head of sales at refrigerant supplier Climalife, looks at the various options available for HVAC chillers.
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.
Rhoss has announced the launch of three new air-cooled water chillers ranges with screw compressors using R513A or R134a refrigerant.
Daikin Applied is set to launch a new addition to its Bluevolution portfolio of R32 products – the R32 Small Inverter Chiller.
Italian OEM Epta announced the availability of a new version of its Eco2Large commercial transcritical CO2 rack that includes integration of its FTE (Full Transcritical Efficiency) 2.0 and ETE (Extreme Temperature Efficiency) technologies during a recent webinar on the Life-C4R – Carbon 4 Retail Refrigeration project.
Environmental test chamber manufacturer Weiss Technik has proven the long-term compatibility of Danfoss AKV expansion valves with its newly developed cryogenic refrigerant R469A.
The FläktGroup’s latest generation of 4-pipe HeaMo Air heat pumps is offered with lower GWP refrigerant R454B.
Daikin has extended its DWSC centrifugal chiller series with the addition of models using the low GWP refrigerant R1234ze.
While Europe continues with the HFC refrigerant phase down, new proposals to be put before the Commission could see further restrictions or even bans on HFCs and HFOs.
The installation of a low charge ammonia chiller system at a major UK food manufacturer’s storage facility is said to have led to a 77.3% reduction in energy consumption.
