Synopsis: Domenii: Energy: Energy colaterale: Refrigeration:

advances in refrigeration technology have struggled to offset the increasing number of units being introduced each year. For example, vending machine sales (EU-27) are expected to continue growing, from 126 000 in 2009 to 200 000 in 2020.

which in turn drives an absorption-refrigeration machine. This machine cools a water-glycol mixture up to negative temperatures of about-10°C."By using heat instead of electricity,

and tested by MEDISCO could really help the Mediterranean and indeed other areas with no conventional means of refrigeration due to a lack of water and nonexistent or unreliable energy sources y

and stored without refrigeration and it would produce answers by changing color so a person could read the answer by eye alone.

Demille and his colleagues built their own apparatus in a basement lab. It is an elaborate multilevel tangle of wires computers electrical components tabletop mirrors and a cryogenic refrigeration unit.

#New material set to change cooling industry"The world refrigeration market is expected to increase by about $7-8 billion by 2018,

"Stadler's team's technological discovery is a promising alternative for refrigeration and air conditioning that can reduce the use of harmful gas fluorocarbons."

Team Ahaar developed an automated refrigeration truck to reduce postharvest waste. First place went to team Innovision from the University of Dhaka, Bangladesh who won $10,

Daikin action is aimed at encouraging manufacturers worldwide to adopt sustainable comfort cooling and heating technologies that use HFC-32, a refrigerant with a lower global warming impact than commonly used refrigerants.

since 2011 to accelerate the phase out of ozone-depleting refrigerants, such as HCFC-22, said Shinya Okada, Daikin senior executive officer. iven the urgent need to address climate change,

Conversion from high-GWP refrigerants is already underway. Last year, the European union enacted the revised F-gas regulation*to reduce the global warming impact of refrigerants.

In the United states, the Environmental protection agency (EPA) is in the process of revising its regulations that establish acceptable alternatives for ozone depleting and high-GWP refrigerants.

In addition, Japan Act on Rational Use and Proper Management of Fluorocarbons, which came into force in April 2015,

encourages conversion from high-GWP refrigerants e

#Technology U s. scientists make tiny invisibility cloak A tiny invisibility cloak has been invented by U s. scientists who are edging ever-closer to a real version of

Emerging"elastocaloric"refrigeration is potentially much more efficient and, unlike vapor compression, relies on environmentally-friendly refrigerants.

In elastocaloric materials a change in mechanical stress can create a change in temperature. In the Journal of Applied Physics("Elastocaloric effect of Ni-Ti wire for application in a cooling device"),a team of researchers from Technical University of Denmark report that the elastocaloric effect opens the door to alternative forms

of solid-state refrigeration that are direct replacements for vapor compression technology. The elastocaloric effect is one of many flavors of"caloric effects"

expensive, require unbroken refrigeration from manufacture to use and up to 12 hours from testing to confirmed diagnosis The test provides rapid, inexpensive, accurate detection of Ebola viral antigens based on colour change within 30 minutes in individuals

No refrigeration required. She then used these silk-stabilised chemicals to design a paper-based test that requires only a serum sample (the clear part of the blood after the red blood cells have been removed) and water to run.

and the third-leading cause of death from food poisoning in the U s."It can grow under refrigeration,

fruits and soft cheeses that are stored under refrigeration.""Currently, the only means of detecting listeria bacteria contamination of food requires highly trained technicians

donated tissues are stored within a medical-grade refrigeration unit in sealed bags filled with a standard preservation solution.

Although the RDT requires refrigeration, this is already available in many health centers in endemic areas,

An inhalable vaccine may eliminate the need for refrigeration which can not only improve shelf life but also enable distribution of vaccines to low-resource areas including many developing countries where there is significant need for better access to vaccines s

In traditional preservation methods, donated tissues are stored within a medical-grade refrigeration unit in sealed bags filled with a standard preservation solution.
