Ammonia

More must be done to lift barriers to natural refrigerant uptake such as restrictive safety standards, the EIA’s Clare Perry told visitors to the EuroShop tradeshow yesterday.

Over 40 papers on alternatives have already been submitted for presentation at the next CO₂ and Ammonia Refrigeration Technologies conference in Ohrid in May.

Since February 27 till March 2, 2017, a meeting of representatives of refrigeration associations of Armenia, Kazakhstan, Kyrgyzstan, Moldova, Tajikistan, and Ukraine as well as working groups from Azerbaijan and Turkmenistan took place in Moscow. It resulted in establishing the Interstate technical committee which will help specialists in refrigeration solve their common problems.

New products for CO2, ammonia and propane refrigeration systems are being launched at leading tradeshow ‘Climatización & Refrigeración 2017’ in Spanish capital Madrid this week.

Low-charge ammonia systems are set to become increasingly popular worldwide, Professor Pega Hrnjak – a leading authority on natural refrigerants – told participants in yesterday’s ATMOsphere Japan conference.

As the global HFC phase-down gathers pace, participants in the first-ever ATMOsphere Japan conference – held yesterday at the Shin-Marunouchi Building Conference Square in Tokyo – heard how policy changes and technology developments are creating new opportunities for natural refrigerants in Japan.

By using natural refrigerants and an increase in energy efficiency, the global warming impact of data-centre cooling systems can be reduced to ‘virtually zero’, an Ecofys report found.

The ATMOsphere Review Panel has selected ammonia case studies from Evapco and Bohn de Mexico to be presented at ATMOsphere America 2017.

The new 10-foot models are part of BAC’s successful closed circuit cooling tower line.

According to the International Ice Hockey Federation (FIH), there are 1,800 indoor ice rinks depending on refrigeration for their ice in the USA, and 3 250 ice rinks in Canada. The most recent ones generally use ammonia as their refrigerant, but many older ice rink systems can still contain thousand of kilograms of R-22.

Leading Japanese manufacturers of natural refrigeration technology see 2017 as a growth year in Japan for CO₂ in commercial refrigeration.

The Food Storage and Distribution Federation and the British Frozen Food Federation have come together along with industry experts to deliver a Safe Management of Ammonia Refrigeration Systems seminar on 16th May 2017. This seminal event will provide suppliers, users, consultants and engineering contractors of ammonia refrigeration systems with key guidance and clarify their legal responsibilities and will be held at the Belton Woods Hotel in Grantham.

140 papers were presented during the successful 12th IIR Gustav Lorentzen conference on Natural refrigerants. CO₂ was the most addressed refrigerant (74 papers), followed by hydrocarbons (34), ammonia (21) and water (4). We present below the summary of a paper along with the direct link where the paper can be downloaded in Fridoc database.

GreenChill webinar with Consumer Goods Forum will take place February 28, as planned; check website for updates on others.

Australian gourmet food firm F. Mayer Imports has commissioned a transcritical CO₂ plant with ammonia chillers.

Mayekawa’s NewTon unit installed at a candy plant consumes 32% less energy than an R507A system, reports ASHRAE Journal.

The Canadian city has already converted most municipal skating and hockey rinks from R22 to environmentally friendly ammonia, with more conversions planned.

The air-cooled units employ CO₂ and water/glycol as secondary fluids as an alternative to HFC systems.
