PCM briefing: Viking touts hybrid cooling system in Australia; thermodynamic law takes a hit in Japan

Ben Welter - Thursday, September 01, 2016

Viking Cold Solutions of Houston introduced its hybrid cooling system at an industry conference in Australia this week. The system, which combines rooftop photovoltaic panels and PCM-based thermal energy storage, is designed to reduce energy costs at supermarkets and cold storage facilities. 

Phase Change Energy Solutions, BASF Education Lab and CALMAC are among the exhibitors scheduled to attend the Greenbuild conference and expo Oct. 5-7 in Los Angeles.

Chart showing 4 phases of substance coexisting at thermal equilibrium• In research that appears to conflict with thermodynamic law, scientists at the University of Tokyo have run simulations showing that four phases of a substance can coexist at thermal equilibrium, where all parts are at the same temperature and pressure. The research "may prove useful in the development of functional phase change materials," according to a university news release, "as it demonstrates that multiple phase transformation can be induced through weak disturbance (perturbation) near the quadruple point."

Emerson is expanding its cold chain presence with the acquisition of two temperature-monitoring companies: Locus Traxx of Jupiter, Fla., and PakSense of Boise, Idaho. Terms were not disclosed.

Ravi Teja, an R&D associate specializing in phase change materials at Pluss Advanced Technologies in India, is a finalist for the Energy Institute's Young Energy Professional of the Year award.
