In a sign of the growing popularity of natural refrigerant systems in U.S. supermarkets, Parker Sporlan’s Micro Thermo, a control and energy management system, is increasingly being used with CO2 transcritical installations in the U.S.
Analysis conducted by technology company Emerson, in conjunction with HVACR research institute ILK Dresden has shown that European retailers could save hundreds of millions by making the right choice of refrigeration system as they transition away from HFCs to sustainable alternatives.
During the One Planet Summit held in Paris in December 2017, Supermarket group Carrefour signed the “French Business Climate Pledge 2018”, thus agreeing to a reduction of CO2 emissions. Carrefour plans to reduce emissions by 40% by 2025 and by 70% by 2025 compared to 2010 levels.
The International Institute of Refrigeration is now calling for abstracts of papers to be presented at the International Congress of Refrigeration (ICR) in Montreal in August 2019.
This will be a year of integrating air conditioning and heating technologies in commercial refrigeration systems, while ejectors will continue to dramatically improve the energy efficiency of CO2 transcritical systems, manufacturers said.
Some manufacturers and end users are expecting low-charge packaged ammonia systems and ammonia-CO2 cascade systems to face increased competition from CO2 transcritical in the industrial sphere, while foreseeing a boom for ammonia heat pumps.
In a bid to increase understanding of transcritical CO2 systems in North America, Hillphoenix’s senior corporate trainer Rusty Walker led a training session in an effort to educate technicians who typically work in industrial plants on the finer points of the technology at the RETA (Refrigerating Engineers and Technicians Association) National Conference, held in Hershey, Pa., September 25-29 2017.
The Kigali Amendment to the Montreal Protocol, which will phase down HFC consumption in developed countries by 85% by 2036 (compared to a 2011-2013 baseline period), will enter into force on 1 January 2019.
With the phase-out of HCFCs (hydrochlorofluorocarbons) under the Montreal Protocol on Substances that Deplete the Ozone Layer progressing, the introduction of alternatives with not only zero ozone depleting potential (ODP) but also low global warming potential (GWP) and improved energy efficiency is becoming an issue of increasing importance, especially in developing countries.
Pursuing a policy of continuous refinement of its products, Dorin has optimised the performance of its top of the range CD400 CO2 compressors.
Mitsubishi Heavy Industries Thermal Systems has added a large-capacity 20hp CO2 condensing unit to its commercial refrigeration line-up in the Far East.
The implications of the European F-gas regulations and phase down will be discussed in a new forum set up for public sector employees in London and the South East.
The permanent IceHotel, opened last year in Jukkasjärvi, Sweden, has been successfully retained this summer thanks to solar energy and a CO2 refrigeration system.
The European F-gas refrigerant training and certification scheme is to be emulated in Argentina as the country seeks to move to low GWP alternatives.
Two Yukon chillers provided by Italian firm Enex serve a new high-efficiency CO2 transcritical refrigeration system with heat recovery at the Abazzia di Novacella winery in the Alto Adige (South Tyrol) region of Italy.
With rapidly rising natural gas prices, a fast growing food processing industry, and the coming HFC phase-down, there is a very large opportunity for high-temperature heat pumps in Australia – including natural refrigerant-based systems – a recent report has found.
In another sign of natural refrigerants’ penetration into Europe’s retail sector, Spanish company Eurofred will begin offering natural refrigerant-based commercial refrigeration solutions.
Carrier Transicold has deepened the frozen range of its NaturaLine CO2 container refrigeration units to achieve and maintain a temperature of -40ºC.
Coming hot on the heels of Maersk Line’s decision to invest in Carrier Transicold’s NaturaLINE container refrigeration system, Singapore-based Seaco Global Limited – one of the world’s leading shipping container leasing companies – has ordered 100 of the units.
With natural refrigerants ready to step in as replacements for f-gases in HVAC&R technology, a workshop held on the margins of the 29th Meeting of the Parties to the Montreal Protocol (20-24 November 2017), organised by the Climate and Clean Air Coalition (CCAC), set out ways to combat growing use of high-GWP HFCs.
