Briefs: Cryocooling in outer space
MELFI (Minus Eighty degrees Celsius Laboratory Freezer) has been developed for the International Space Station (ISS) under a European Space Agency (ESA) contract for NASA. It is used to preserve biological and scientific samples until they return...
Briefs: Night wind
A European project designed to store wind energy produced at night in refrigerated warehouses then to use this energy during daytime peak hours has been launched in The Netherlands. Wind turbines are being installed and cold store refrigeration...
China
In the People's Republic of China, targets have been recently set by the 11th Five-Year Plan to cut energy consumption by 20% per unit of GDP between 2006-2010. This entails strict energy policies in all economic sectors, including refrigeration...
US
The US Department of Energy recently announced that the energy efficiency criteria necessary for refrigerators to be granted the Energy Star® label are to become more stringent. In order to qualify, refrigerators will need to be 20% more efficient...
Climate change issues: IPCC Report 2007
The IPCC 4th Assessment Report Climate Change 2007, which was released in May 2007, provides very valuable figures on greenhouse gas (GHGs) emissions, including those of fluorinated gases (CFCs, HCFCs, HFCs) used in refrigeration. - In 2004, the...
Climate change issues: G8 statement
The Group of Eight leading industrialized nations (G8) met with 5 major emerging countries (Brazil, China, India, Mexico and South Africa) early June in Heiligendamm and published a statement demonstrating a far greater will to address climate...
Ozone layer issues: Montreal Protocol
A recent policy article recommends "further adjustments to strengthen the Montreal Protocol and provide further insurance against the threat of abrupt climate change". According to the authors, "the Montreal Protocol's successful work to protect...
Ozone layer issues: China
China Closes Ozone Depleting Chemical Plants. On July 1, China, the world's largest producer of CFCs and halon, shut down five of its six remaining plants, putting the country two and a half years ahead of the Montreal Protocol's 2010 deadline for...
Briefs: BOCOG
The Beijing Organizing Committee for the Games of the 29th Olympiad (BOCOG) - in co-operation with China's State Environmental Protection Administration and UNEP - is addressing stratospheric ozone protection as part of the 2008 Beijing Olympic...
Briefs: HFC-free refrigeration, naturally
Three more companies have joined Refrigerants, Naturally!, a unique public-private partnership that promotes HFC-free refrigeration technologies that protect the Earth's climate and ozone layer for "point-of-sale" applications. The founding...
R&D topics
In this issue of the Newsletter dedicated to environmental issues, we present several initiatives related to promising refrigeration technologies or applications which have the potential to decrease the environmental impact of refrigeration plants...
Solar Air conditioning
With high summer temperatures, air-conditioning and thermal comfort are increasingly important issues, but raise the challenges of high energy consumption and of environmental consequences. Three recent projects use solar energy to operate...
Radiative Cooling in the Sub-Saharan Desert
A new way of lowering temperatures without using electricity has recently been developed. Iterrae, a French company, has discovered a way of using radiative cooling, a phenomenon that takes place at night, when the Earth is cooled by the 0 K...
Ice storage
Ice storage is not only beneficial in economic terms, it is also energy-saving, noise-free and helps extend the life of the systems. It consists in keeping a certain amount of ice, as a way of storing "cold", in order to use it later. It was...
Nanotechnology applications: Nanopackaging
Nanopackaging market worth billions Global sales of nanotechnology-related products approached 739 million € last year, and the food packaging industry could be worth as much as 22 billion €, according to a new study that provides an insight into...
Nanotechnology applications: Nano-insulation
It is claimed that a new material using nanotechnology and consisting in a micron-thickness film with tiny cells containing a vacuum could reduce the energy consumption of refrigerating units by as much as 20%. Nanoskin was developed by General...
Briefs: Thermoacoustics
A project led by the University of Nottingham aims at developing a device acting as a refrigerator, cooker and power generator, using biomass fuels such as wood. The SCORE (Stove for COoking, Refrigeration and Electricity) is based on the use of...
Briefs: Water savings thanks to hybrid condensers
Hybrid condensers offer significant water savings versus traditional water-cooled and evaporative condensers. They also make it possible to reduce energy consumption and refrigerant charge. In Australia, where water savings are a major issue since...
Briefs: Canberra Airport
Canberra Airport has recently ordered a cutting edge air-conditioning system using waste heat in order to generate heat and cooling which will be installed in December 2007. The heat is recovered from the 1200 kW gas generator that produces...
Briefs: Bright future for cool LEDS
Light-emitting diodes (LED), which are replacing traditional light sources in many fields, are beginning to be used in refrigerated and frozen display cabinets and are likely to make a big impact on refrigeration for several reasons. They are more...
Out of the ordinary: Microcebus danfossi
Danfoss has given its name to a lemur species recently discovered in Madagascar by researchers from the veterinary college Tierärztliche Hochschule (TiHo), in Hanover, Germany. The tiny (30-60 g) lemur is named Microcebus danfossi after Danfoss -...
Improving Cold Storage in Pakistan
The Pakistani government has recently announced that it will provide funds to the national food sector, in order to improve cold storage facilities. The scheme, called ‘Cool Chain and Cold Storage for Horticulture Products' aims at mitigating the...
A Research Project on Magnetic Refrigeration in Denmark
Very few laboratories are dedicated to research on magnetic refrigeration, but their number and the number of countries involved is slowly growing. The Danish Council for Strategic Research has recently donated 14 million DKK to the Risø National...
ARI launches a certification program for commercial refrigeration equipment
The Air-Conditioning and Refrigeration Institute (ARI) has announced the launch of a new certification programme for commercial display and storage cabinets. There are 25 other ARI certification programmes, all of them aim at giving consumers...
World AC and compressor trends
In its recent report, JARN estimates that the HVAC&R market in 2006 was about 66 billion USD and about half of sales were air conditioners and related products. - Regarding the AC market, China, the US, Japan and major European countries make...
