(Image courtesy of Glaciem Cooling Technologies) Glaciem Cooling Technologies in conjunction with researchers from the University of South Australia have developed a unit, based on a CO2 refrigerant that uses dew point technology to pre-cool air before it enters the refrigeration system’s condenser. The system also has a thermal energy storage component that can store…

Details of the project can be found at http://www.architectour.net/opere/opera.php?id_opera=6869&nome_opera=Marxer%20Haus&architetto=Falkeis%C2%B2architects&language=1 and http://www.puretemp.com/pcmatters/inspired-by-nature-marxer-haus-takes-wing-in-liechtenstein. As well as many other sustainable features, the apartment block utilises movable “wings”. These climate wings contain 1.4 tonnes of Rubitherm PCMs enclosed in aluminium tubes. …
(Image and text courtesy of MIT) Researchers at the Massachusetts Institute of Technology have found a way to prevent wax-based PCMs from releasing their stored heat until triggered by light. MIT’s Professor Jeffrey Grossman stated that “the trouble with thermal energy is, it’s hard to hold onto it,” So his team developed what are essentially…
