Ozone-depleting chemicals detected by scientists in the atmosphere in 1951 – decades earlier than expected
An international team led by the University of Bremen, Germany, has uncovered evidence of ozone-depleting chlorofluorocarbons (CFCs) in the atmosphere as early as 1951. This finding pushes back the known...

Out of the ordinary: ATLAS LEGO® model
As part of an outreach project at the Niels Bohr Institute Sascha Mehlhase recently designed and built a model of the ATLAS experiment in LEGO® bricks. It illustrates all details, from the muon and magnet system to the innermost pixel...
Plans for a floating LNG factory
This new type of floating factory could give access to off-shore reserves, without the use of long and expensive ocean-bed pipelines
China’s plans to accelerate HCFC phase out
Through the HCFC Phase-out Management Plan (HPMP), 45 000 metric tonnes of HCFCs are to be eliminated
Low-GWP alternatives in refrigerated transport
An EPA fact sheet provides full details on alternatives to HFCs: R744, R717, hydrocarbons and HFOs, and describes alternative technologies: cryogenic systems, secondary loop systems, eutectic plates, hermetic and semi-hermetic vapour-compression...
Cryoablation benefits
Cryoablation involving freezing balloon technology is claimed to enable highly precise targeting of the tissues to be destroyed without damaging the surrounding tissues.
European Union: new projections regarding CO2 emissions
A report published on behalf of the European Partnership for Energy and the Environment (EPEE) by French research organizations ARMINES/ERIE at the end of 2011 reveals that CO2 eq. emissions from refrigeration, air-conditioning and heat pump...
China: what refrigerant to replace HCFCs?
In December 2011, the China Household Electrical Appliances Association (CHEAA) issued China’s first industry technology roadmap. For the refrigeration industry, the roadmap aims to increase energy efficiency by 20% by 2015, and by 2020 by another...
Refrigerated display cabinets: a growing global market
A comprehensive global report on refrigerated display cabinets released by GIA predicts that the market will grow to over USD 5.34 billion by 2017.

Frozen fish generates less waste
A recent study conducted by the UK Waste Resources Action Programme (WRAP) on waste in the fish and seafood supply chain shows that there is less retail waste in frozen fish products (1%) than in fresh fish (5%).
A design for a liquid-nitrogen-powered vehicle engine could provide an alternative to batteries and fuel cells
The engine developed by Dearman Engine Company (DEC), which is driven by the pressure created as liquid nitrogen (LN2) returns to its gas form could provide a way of powering a vehicle without producing CO2 tailpipe emissions but with a longer...
Converting waste heat into cooling
A prototype that has succeeded in converting waste heat into cooling capacity could lead to new solutions to harness excess energy produced by systems.
Cryogenic tyre grinding
Liquid nitrogen or other cryogenic fluids can be used in order to process used tyres, as temperatures under -80°C render the rubber brittle and easy to shatter.
HFO1234ze prototypes finally released
The prototype is said to be suitable for outdoor air-cooled chiller applications
New Eurovent certification programme for cooling towers
Eurovent, the European Certification body, has developed a certification programme for the thermal performance of cooling towers.
Arkema and Honeywell dismiss one of the claims in their suit
