Connect with PCM experts and industry leaders on LinkedIn

Ben Welter - Wednesday, March 25, 2015

Phase Change Matters logoNew on LinkedIn: A group devoted to the discussion of phase change material and thermal energy storage, a place for PCM and TES experts and industry leaders from around the world to gather and share ideas. It's called Phase Change Matters, and it's intended as a highly interactive complement to the blog and newsletter of the same name.

The first topic up for discussion: PCM and off-peak cooling systems:

TES pioneers like CALMAC and Ice Energy have been installing ice-based energy storage systems for years. And district cooling has been around for decades. What are the main barriers to wider adoption of phase change material in these types of thermal energy storage systems? Complexity? Education? Cost?

You are invited to join the discussion. Here's a link to the group:

Frigesco flash defrost system wins ACR News Award

Ben Welter - Tuesday, March 03, 2015

Frigesco Ltd.'s low-energy flash defrost system was among the winners at last week's ACR News Awards in London, earning Refrigeration Product of the Year honors.

The British company's technology harnesses waste heat to defrost refrigeration systems more efficiently, reducing supermarket cooling costs by up to 20 percent. Phase change material is used to store the waste heat. 

Other ACR winners include Toshiba, Cool Designs Ltd. and Sainsbury Triple Zero Stores.

Western Refrigeration using PCMs in coolers, freezers

Ben Welter - Tuesday, December 16, 2014

In countries like India, where power failures are commonplace, refrigerators and freezers need backup. Western Refrigeration and other manufacturers are incorporating phase change material in their coolers and freezers to keep food cold during outages -- and help the appliances operate more efficiently.
