United States
A bill aimed to reform for the first time since 1976 the US Toxic Substances Control Act (TSCA) was introduced in the USA on April 15, 2010. The new legislation will require manufacturers to prove the safety of every chemical - including...
Briefs: Lifesaving pocket refrigerator
During the severe heatwave in Europe in 2003, Uwe Diegel realized that his brother was encountering problems keeping his insulin refrigerated while travelling. So the inventor decided to invent a pocket refrigerator based on the Peltier effect...
Figures: EU electricity consumption
A report issued by the European Commission's Joint Research Centre (JRC) shows that energy efficiency measures - such as labelling and minimum energy efficiency standards -together with national policies and incentives are contributing to...
Figures: refrigerated storage capacity in the US
In its January 2010 report, the US Department of Agriculture mentions that the general refrigerated storage capacity in the US totaled 107 million gross m3 in October 2009, an increase of 14% from October 2007. Usable refrigerated space in general...
Trends: compressors
- Global compressor sales JARN has published an extensive overview of compressor markets in 2009. On the whole, the compressor market has suffered from the decrease in the air-conditioning market (-2.9% compared with 2008). Sales of rotary...
Briefs: Frozen vegetables more nutritious than fresh?
According to a study conducted by the Institute of Food Research (UK) on behalf of frozen food giant Birds Eye, frozen vegetables can be more nutritious than supposedly fresh supermarket produce. Fresh vegetables can lose up to 45% of important...
Briefs: Fridges used as monitoring tools
Sensor-equipped domestic refrigerators are found to be a useful means of improving and protecting the well-being of senior citizens living on their own. Thanks to Carlston University's TAFETA Smart Systems for Health, residents in Ottawa Community...
Briefs: ozone hole
The Earth's ozone hole is slowly mending: this is considered a big victory for environmental policy makers. But in a new report, scientists say there is a downside: its repair may contribute to global warming. As it happens, the hole led to the...
Briefs: LCCP
The Air-Conditioning and Refrigeration Technology Institute (ARTI) has opened bidding for a new research project to establish a standardized methodology to calculate the Life Cycle Climate Performance (LCCP) for stationary heating, ventilation,...
Briefs: UNEP
The UNEP HCFC phase-out and mobile air-conditioning project has two components: - "JumpStart" project to encourage developing countries to expedite their compliance with the HCFC phase-out obligations and to adopt environmentally friendly...
Out of the ordinary: ice cream
A group of New Zealand scientists has developed a new therapeutic to help cancer patients recover from chemotherapy. Development of the ice cream, named ReCharge, began 8 years ago with the formation of LactoPharma, a collaborative research...
Out of the ordinary: trapped cat
A cat has survived despite being trapped for at least a month in a frozen food warehouse which operates at -33°C. Frosty, as the cat has been appropriately named, had lost one ear and vets had to amputate his other ear and his tail after the...
Optical refrigeration
A team in New Mexico University has created the first-ever optical cryocooler that could be applied to airborne and spaceborne sensors. It uses optical refrigeration which could enable miniaturization, an alternative to bulky mechanical...
Refrigeration’s contribution to CCS
Led by IFP (France), the European research project Cocate - which brings together 8 other research and industrial partners worldwide for a budget of 4.5 million € - tackles the problems of rolling out a shared transportation infrastructure capable...
Cryogenic applications: cryogenic system to recover volatile organic compounds
In 2007, in France alone 12 000 tonnes of volatile organic compounds (VOCs) were released from service stations, i.e. 1% of all such emissions in France. VOCs from service stations are detrimental to health and the environment and increasingly...
Cryogenic applications: India
India is developing semi-cryogenic propulsion technology using kerosene as a propellant to enhance its capability to launch satellites in the 6-tonne class. The technology utilizes liquid oxygen and aviation-grade kerosene instead of liquid...
Cryogenic applications: Spar Netherlands is implementing CO2 refrigerated transport units
The contract was awarded following a successful testing period during which Thermo Kingfs innovative CryoTech CO2 cooling units were tested for operational and environmental performance. Spar has already begun using the innovative technology and...
CO2 supermarkets: Tesco
Designed as Tesco's first zero-carbon store, the new store at Ramsey, Cambridgeshire, UK, is completely HFC-free. The supermarket is hence using natural refrigerants CO2 and hydrocarbons throughout its refrigerators, freezers, heating, ventilation...
CO2 supermarkets: Sainsbury’s
Sainsbury's has doubled the size of its supermarket in Durham, UK, and has cut energy consumption by 10%. The store will be "carbon negative" thanks to a number or technologies including ground-breaking CO2 refrigeration technology and on-site...
CO2 supermarkets: CAREL
CAREL and the French hypermarket chain Carrefour have joined forces to develop the first subcritical CO2 plant in a supermarket in Turkey. The Istanbul installation uses a cascade system that supplies the low-temperature units with R744. To...
Briefs: Chip cooling innovations
IBM researchers demonstrated a prototype that integrates a computer chip cooling system into 3-dimensional stacks by piping water directly between each layer in a chip stack. These so-called 3D chip stacks, which take chips and memory devices that...
Briefs: Thermoacoustics for air conditioning
The Palo Alto Research Center (PARC), is developing a new form of refrigeration for cooling at room temperature, based on thermoacoustics, which was previously used only for cryogenic temperatures. The technology PARC developed is claimed to...
Briefs: Thermal storage in public buildings in California
Energy storage equipment is to be installed in 28 city buildings and 250 local businesses as part of a partnership between Glendale Water & Power and Ice Energy. The USD 4.25 million programme will install 1.5 MW of energy storage and marks...
