PCM briefing: 2-day training school in Barcelona; Alexium to launch foam bedding, 'top of bed' products

Ben Welter - Friday, March 15, 2019

A training school on thermal energy storage material selection, optimization and characterization will be offered May 20-21 at the University of Barcelona. The university's Center for Design and Optimization of Processes and Materials is hosting the event. The fee is 230 euros. Lecturers include Camila Barreneche, Ana Inés Fernández, Mercè Segarra and Pablo Gamallo of the University of Barcelona; Luisa Cabeza and Alvaro de Gracia of the University of Lleida, Spain; and Yulong Ding of the University of Birmingham, United Kingdom.

Alexium International Group Ltd. was among the companies making presentations this week at the Gabelli & Company Specialty Chemicals Conference in New York City. Alexium, based in Greer, S.C., and Perth, Australia, makes flame-retardant and PCM-enhanced fabric treatments. Among its "cornerstone" initiatives is a plan to launch a new product line in early 2019, Alexicool FM, the application of the company's Alexicool technology to foam mattress and "top of bed" products.  

• Thermal materials specialist va-Q-tec reports that its annual revenue grew by 8 percent in 2018. The company, based in Würzburg, Germany, said sales from its products business, including vacuum insulation panels and phase change materials, increased by 12 percent to 20.1 million euros, up from 18 million euros in 2017. However, its earnings fell by 58 percent, to 3 million euros. It blamed earnings decrease on investment costs and a rise in sales from its lower-margin products business.

• Australian researchers are challenging the belief that 22° C (72° F) is the optimum temperature to maintain worker productivity. A team from Griffith University’s School of Engineering and Built Environment and Cities Research Institute performed an extensive review of research literature on the relation of moderate thermal environment to cognitive performance. "From the research point of view," the lead researcher, Fan Zhang, said in an interview with the Cooling Post, "there is no empirical evidence that this temperature [22ºC] should be maintained. In effect, it is inconsistent with the already-established comfort benchmarks such as ASHRAE 55-2017, which recommends a summer time thermal comfort zone of 23-26ºC. I would say 23-26 is a safe summer temperature set point range for western developed countries."

PCM briefing: Boston food bank installs Viking Cold TES system; 2-day workshop on microencapsulation

Ben Welter - Friday, March 08, 2019

The Greater Boston Food Bank is reporting a 75 percent reduction in energy use during targeted peak hours since the beginning of the year after installing a Viking Cold Solutions thermal energy storage system for the refrigeration units at its 117,000 square-foot, high-efficiency Yawkey Distribution Center.

Maria Telkes• To mark Women's History Month, 24/7 Wall St. has compiled a list of "50 Things You Never Knew Were Invented by Women." MIT researcher Maria Telkes, a pioneer in the field of solar thermal storage, is on the list at No. 30. She created the first solar-heated system for her home in Dover, Mass., in 1947. The system used a phase change material, sodium sulfate decahydrate, to store solar heat.

• Researchers at the Chinese Academy of Sciences say they have developed an inexpensive, flexible film that renders the objects it covers virtually invisible in infrared light. The film's main components are DuPont's Kevlar, a synthetic fiber with high tensile strength, and polyethylene glycol, a phase change material that can store heat. 

• French utility ENGIE has begun production at one of South Africa’s largest renewable energy projects, the 100MW Kathu Solar Park. The concentrated solar plant's molten salt storage system provides up to 4.5 hours of thermal energy storage.

• The Southwest Research Institute is hosting a two-day workshop on microencapsulation March 25-26 in San Antonio, Texas. The introductory course will cover topics such as atomization (spray drying, spray chilling, spray congealing) and spray coating (fluid bed coating, granulation). The cost is $950.

• The University of California is winning praise for its decision to end its subscription deal with Elsevier, the world’s biggest publisher of scientific journals. UC is the first major university system to push for open-access publishing. UC, which had been paying $11 million a year to Elsevier in subscription fees, generates about 10 percent of the research produced in the United States. “It’s ridiculous that, in this age of the internet, researchers are paying huge fees for access to academic papers and for publication of their own work,” the San Jose Mercury News said in a March 6 editorial.

MIT researchers have developed a way to use light to trigger the storage and release of waste heat from car engines and other sources. "Once melted and activated by ultraviolet light, the [phase change] material stores the absorbed heat until a beam of visible light triggers solidification and heat release," Phys.org reports. "Key to that control are added molecules that respond to light by changing shape from one that impedes solidification to one that permits it."
