Posted March 08, 2018 09:29:16 As the years have gone by, many people have noticed a decline in the sound of their refrigerators.
The reason is simple: Most refrigerators are now made of plastic, which is prone to rust.
When it’s broken, the plastic can cause it to explode.
Now, the researchers from the University of Pennsylvania are trying to find a way to create a vacuum that can keep those explosions at bay.
“We’re trying to create something that is really quiet that you don’t hear,” said Dr. James P. Zuckerman, the lead author of the study, in a press release.
The research is published in the journal Environmental Science & Technology.
“What we’re trying do is take the sound out of a refrigeration system and replace it with something that you can feel, so it’s a tactile sensation.”
Zuckerman is also a professor of mechanical engineering at Penn and a member of the Penn Energy and Environmental Engineering group.
“The refrigerator is the most noisy component of our life cycle,” he said.
“When we move, it’s always in the vicinity of people.”
A lot of refrigerators in the U.S. and elsewhere in Europe use a single, single-fan system, which allows the air in the fridge to flow into the room.
The fan blades are designed to spin at a constant speed.
A vacuum cleaner would be able to remove that airflow and force it out.
Zuckserman’s team made their idea using a “silent vacuum,” which is a vacuum made of materials that are both extremely thin and very flexible.
The researchers also made a new type of vacuum cleaner, a type that has two air chambers and a single fan.
The vacuum cleaner can be used to remove dust, debris, and other odors.
“You’re not trying to vacuum up the entire room,” said Zuckersman.
“Instead, you’re trying not to blow up the refrigerator itself.”
Zuckserman said that the vacuum cleaner could also be used for cleaning food and other items, as well as for “reactive” cleaning of the refrigerator.
The study has a number of limitations.
The scientists are still trying to figure out the best way to control the sound.
The refrigerators used in the study are only about five feet long, which means the vacuum could be a problem for people who are shorter than 5 feet.
“There are ways to make it smaller and smaller and still get the sound in,” Zuckert said.
The device can also be easily destroyed by fire, so the researchers will be testing the system in a closed-off area before they decide whether to make the new one commercially available.
“If we do a commercial version, we would be doing a much better job,” Zucksert said, noting that the system would be safer.
The Penn team also plans to study the acoustic characteristics of the vacuum, which could also help determine whether the system is effective.
“It’s still a research project,” Zinkser said.
Zuckerman is a former assistant professor of electrical engineering and computer science at the University at Buffalo, where he also worked on a system that was tested in the field.
He said the team plans to continue the research with a team of researchers.
