PCM briefing: Ice Energy seeks distributors in Australia, Mexico and Saudi Arabia; Thermetrics' new manikin can measure PCM effects

Ben Welter - Friday, August 31, 2018

• In an interview with Energy Storage Report, CEO Mike Hopkins discussed Ice Energy's plans to distribute its ice-based thermal energy storage technology in Australia, Mexico and Saudi Arabia. In June, the California company announced a $40 million cash infusion from Argo Infrastructure Partners to finance the delivery of Ice Energy's residential and commercial thermal storage contracts.

Thermetrics manikin ANDIThermetrics says its new ANDI sweating thermal manikin has the "unrivaled ability" to measure both positive and negative heat flux and to respond to changing environmental conditions with "unprecedented" speed and accuracy. The new manikin was unveiled this week at the 12th International Meeting of Manikins and Modeling, hosted by the Swiss research institute Empa, in St. Gallen, Switzerland. The manikin can be used to evaluate the thermal performance of apparel, blankets and seats, as well as quantify the cool-to-touch or warm-to-touch temperature-buffering effect in fabrics containing phase change materials.

Viking Cold Solutions says the thermal energy storage system the company installed at a 93,000-square-foot frozen food distribution center in Richmond, Calif., has reduced peak period energy consumption by up to 43 percent and reduced overall freezer energy consumption by 35 percent. Viking installed the system at the Dreisbach Enterprises warehouse earlier this year. Plastic panels filled with a proprietary salt hydrate are installed evenly throughout the warehouse atop the existing product racks. The PCM absorbs heat as it melts, allowing chillers to run less frequently and still keep the warehouse within a few degrees of the target temperature. The system also includes intelligent controls and sensors to optimize energy use and alert managers to temperature abnormalities, equipment failure and power outages.

PCM briefing: AI tool could transform chemistry; Peli BioThermal opens Tokyo service center

Ben Welter - Monday, April 09, 2018

An artificial-intelligence tool that has digested nearly every chemical reaction ever performed could transform the chemistry world, reports Nature. The tool, developed at the University of Münster in Germany, uses "deep-learning neural networks to imbibe essentially all known single-step organic-chemistry reactions — about 12.4 million of them. This enables it to predict the chemical reactions that can be used in any single step."

Pelican BioThermal plans to open a service center in Tokyo next month to service its reusable Credo Cube temperature-control shippers, including refurbishment and repair. The center will also serve as a network station for the company’s Credo on Demand rental program.

So, which PCM product idea was phony?

Ben Welter - Monday, January 08, 2018

In 2017's final issue of Phase Change Matters, we challenged readers to identify which of these PCM product ideas was phony: an edible additive for chocolate, a feminine pad with cooling properties, a cooling pad for chickens, a thermally responsive bra and a temperature-controlled shipping container for mosquito eggs. 

It was a trick question: All five product ideas were serious inquiries submitted to Entropy Solutions in the past year. Thanks to Holger Böhme, Shaun Mann and Kosheela Poo Palam for submitting answers - and for subscribing to our newsletter. Each will receive a PureTemp temperature-control coffee tumbler.

Which PCM product idea is phony? Answer correctly for a chance to win a PureTemp mug

Ben Welter - Tuesday, January 02, 2018

PureTemp tumbler Entropy Solutions receives a dozen or so inquiries each week, most of them serious questions about PCM products, pricing and suitability for various applications. But some inquiries stretch the bounds of believability. Can you identify which of the product ideas below is fake? 

Send your answer to bwelter@puretemp.com. Five winners will be randomly selected from correct entries received by Jan. 4. The prize: a prototype coffee tumbler developed by Entropy Solutions several years ago, a product idea that was totally legit.

NOTE: You must be a Phase Change Matters subscriber to submit an entry. Representatives of organizations attending the first meeting of the PCM Industry Association of North America in October know the answer and are not eligible for this contest. Good luck to all the contestants!

Chocolate1. Mmm chocolate

We are exploring new ingredient technologies to produce a chocolate product that will release heat when it is consumed. Standard chocolate produces a minor cooling effect when it's melting in the mouth – the main fat is cocoa butter. The idea is to develop a new filling fat/oil that will release heat when consumed.

2. Premium padsWonder Woman

I represent a consumer goods company that is seeking materials that could help the feminine pad feel ‘cool’ in order to increase the comfort of use, especially when female is engaging in activities such as boxing, distance running and other extreme athletic challenges.

Chickens3. Chicken helper

I am hoping phase change materials could help solve a problem I have. First, I am completely serious. Second, here is the problem: I live in Texas and have 10 back yard laying hens. It is hot. Chickens start to go into heat stress at 85 degrees. Is it possible to enclose PCMs into a sort of pad for my chickens to rest near during the day?

Golden Girls4. Hot flashes

I am interested in using your product for a product I am developing for my design thesis. I am trying to make a responsive bra that senses a hot flash, and responds by turning on peltiers and "conducting" the cold through some sort of gel medium to the skin. Are any of your products the right thing for this?

Mosquito eggs5. Mosquito eggs

I'm wanting to ship mosquito eggs and need the parcel to stay dry, and within a prescribed temperature range of 10-35 degrees for up to three days. Would you be able to recommend a particular product of yours which could meet these requirements?

Patent application: Thermally insulated VIP sandwich shipper

Ben Welter - Thursday, November 30, 2017

U.S. patent application 9828165 (applicant Sonoco Development Inc., Hartsville, S.C.):

"A thermally insulated VIP sandwich shipper for a temperature sensitive payload is provided. The shipper comprises an outer shell, an inner shell and vacuum insulated panels sandwiched therebetween. The outer shell and the inner shell may be unitary rigid structures made of an expanded foam material and comprising a bottom having a perimeter and sides extending from the bottom perimeter and terminating in a rim. The inner shell rim may be spaced from the outer shell rim to define a gap, the gap being sealed to create an enclosed space within which the vacuum insulated panels are located. Each vacuum insulated panel may be oriented substantially orthogonally to at least one adjacent vacuum insulated panel and have an edge that abuts the adjacent vacuum insulated panels."

The UV-activated thermal energy storage material shows the rapid crystallization and heat discharge upon visible light (blue LED) illumination. (Grossman Group at MIT)MIT researchers have combined conventional phase change material with an organic compound that responds to a pulse of light. "The new system," MIT News reports, "uses molecular switches that change shape in response to light; when integrated into the PCM, the phase-change temperature of the hybrid material can be adjusted with light, allowing the thermal energy of the phase change to be maintained even well below the melting point of the original material." The system could be used in a thermal battery to store heat from the sun or any other source and release the heat when needed.

Stanford University researchers have developed a reversible fabric that keeps skin a comfortable temperature whatever the weather. "On one side," Stanford News reports, "a copper coating traps heat between a polyethylene layer and the skin; on the other, a carbon coating releases heat under another layer of polyethylene." The fabric can either warm or cool the wearer, depending which side faces out.
