Revolutionary New “Science Fridge” Coming Soon To A Kitchen Near You
March 1st, 2015 by Tina Casey
Getting a handle on energy-gobbling household appliances is a key part of the US Energy Department’s carbon management toolkit. In the latest development, a new energy-efficient refrigerator — make that hyper-super-duper-efficient — is now in the works, thanks to a partnership between Oak Ridge National Laboratory and global appliance innovator Whirlpool Corporation.
The last time the Energy Department put household gizmos in its crosshairs, it was to implement a Bush-era regulation that ditched conventional light bulbs in favor of more efficient technology. That caused quite an uproar among the usual suspects, but we’re guessing that this new energy-efficient refrigerator thing will cause barely a ripple. Or, won’t it?
The New Energy Efficient Refrigerator
CleanTechnica wouldn’t cover a new refrigerator unless it was a very special new refrigerator (or unless it was full of beer), and this one certainly doesn’t disappoint.
It’s going to be co-designed by the Energy Department’s Oak Ridge National Laboratory (ORNL) in Tennessee, so all of us taxpayers can go give ourselves a pat on the back.
The award-winning lab has some serious brainpower working away within its walls, to the tune of thousands of engineers and scientists on staff, visiting, or using the facility, all helped along with an annual budget of $1.4 billion.
ORNL’s roots go back to the 1943 Manhattan Project and, more lately, it’s been known for clean energy and sustainability R&D including next-generation energy storage, solar cells based on spinach, and electric vehicle batteries.
Our expectations are high and so are ORNL’s. According to the lab’s press materials, the goal is to design an energy-efficient refrigerator that uses less than 1 kilowatt-hour daily.
This is definitely not your father’s refrigerator, because depending on how old your father is, in the 1970s, his refrigerator would have used something in the range of 4 to 5 kilowatt-hours daily.
Today’s models range around 1.5 kilowatt-hours, so getting that down below 1 kilowatt-hour is a huge improvement. Here’s how the numbers stack up, according to ORNL’s director of Building Technologies Research & Integration Center:
If every refrigerator in the U.S. were replaced with the advanced refrigerator design, the projected primary energy savings would be 0.56 quads per year—the equivalent of 100 million barrels of oil.
The Magic Of The Linear Compressor
If you think this is one of those things that will take forever to get out of the lab and into your kitchen, guess again. The folks at ORNL and Whirlpool already have an idea how this is all this is going to come about, and the key is a little device called Wisemotion.
Wisemotion is a new type of linear compressor (a compressor is the part that makes your fridge frigid), launched by global compressor whiz Embraco just last April.
According to Embraco, without any other enhancements, Wisemotion gets you about 20% in energy savings. To gild the sustainability lily, the new compressor uses about half the raw materials of a conventional compressor, mainly by virtue of its compact size.
The real magic is in the use of a refrigerant gas that also lubricates the compressor, eliminating the need for oil.
If you want to see a nifty video of Wisemotion in motion, check this out:
Also, because the new compressor is so small, you can park it just about anywhere in the fridge, and this should have refrigerator designers all over the world practically salivating over the prospect of designing a refrigerator that is not shaped like a… well, like a refrigerator.
No word quite yet on all the other energy-efficient enhancements will arise from the ORNL-Whirlpool collaboration, but speaking of tiny houses, Whirlpool is the brains behind a mini-kitchen centered around a thermoelectric refrigerator, and if you’re thinking that probably belongs on the Space Station…
… you’re right. Whirlpool is happy to note that the mini-kitchen in the photo above is the result of a 1960s-era contract with the federal government, so time for another group hug, you taxpayers. It was used in the Gemini, Apollo, and Skylab space programs.
Also in case you missed it, in January, Whirlpool announced that it’s buying into an $18 million wind energy project that will offset about 22% of the energy used at its plant in Findlay, Ohio.
