Patent application: Portable apparatus using PCM to create temperature stable environment

Ben Welter - Friday, February 14, 2020

U.S. patent application 20200041147 (assignee Fruition LLC, Lexington, Mass.):

"A carrying case utilizes a layer of phase change materials and a thermal insulation layer in order to provide a temperature-stabilized environment for enclosed payloads such as musical instruments during transport through an environment in which temperatures differ greatly from those to which they are normally exposed. In one aspect, the phase change materials and thermal insulation provide an extended period of temperature constancy, without the addition of either active thermal control or excessively bulky insulation."

The brewer describes the beer as "somewhere between a solid and a liquid... a Phase Change of sorts."  

• More than 170 speakers are lined up for the 14th International Conference on Advanced Building Skins, to be held Oct. 28-29 in Bern, Switzerland. The Japanese architect and Pritzker laureate Shigeru Ban will deliver the keynote address. Thomas Friedrich of Innogration GmbH, Germany, will discuss "collection of thermal energy from the façade" and "decentralized PCM storage elements for saving thermal energy." Damien Mathis of Ai Environnement, Paris, will give a presentation on the "thermal performance of engineered wood flooring impregnated with phase-change materials." The registration fee is 680 euros and includes the conference documentation as well as meals during both days. Participants who register by Aug. 30 will receive a 10 percent discount.

Patent application: A passive temperature control system for transport and storage containers

Ben Welter - Thursday, July 18, 2019

U.S. patent application 20190219320 (applicant Softbox Systems Ltd., Long Crendon, Great Britain):

"The present invention relates to the field of the transportation and storage of goods and to a passive temperature control system for such a transport and storage containers. The present invention seeks to provide a system that can enable goods to be securely and reliably transported and stored for limited periods within specified temperature ranges. Pharmaceuticals, proteins, biological samples and other temperature sensitive products, including food items, are regularly shipped in containers year round and are subjected to a wide range of temperatures. Though they are shipped in insulated containers and/or climate controlled environments, the temperature stability of the shipping containers can be significantly improved by utilising suitable phase change materials in an ordered fashion. The present invention provides a simple solution to the maintenance of temperature profiles for the transport and storage of temperature sensitive products."

Mike HopkinsIn a LinkedIn post, former Ice Energy CEO Mike Hopkins shared his take on two of the California company's competitors in distributed thermal energy storage. "Look at @CALMAC, a Portfolio of Trane - been in our industry forever, good product, but haven't been able to secure utility deals because their large bespoke systems make it too risky to commit to MWs in a location on a schedule," wrote Hopkins, who is now CEO at Bakken Midstream. "Relative newcomer [Axiom Exergy] came to market with their #refrigeration #battery. Good concept but not plug and play. Not surprising, they seem to have recast themselves as a #cloud based power management company."
