Does Vacuum Insulation Make Sense?

first_imgConvection is the transfer of heat by moving molecules from one place to another. Warm air rises, and these convection currents carry heat — for example, this is the primary means that heat is delivered to a room from baseboard convectors (often called radiators). In a vacuum there are far fewer air molecules, so convection of heat nearly stops.Only radiant heat flow occurs to a significant extent in a vacuum, because radiation is not dependent on air molecules. That’s why low-emissivity surfaces are so important in vacuum panels. The Stanley Thermos bottle has a very shiny, low-emissivity (low-e), inner surface that helps to control radiant heat transfer; the same sort of low-e surface is included in various vacuum insulation panels.The net result is that an inch-thick vacuum insulation panel can provide a center-of-panel insulating value of R-25 or even more — compared with R-6 to R-7 for standard rigid foam insulation. I’ve recently worked on revising the BuildingGreen Guide to Insulation Products and Practices (available as part of a webcast), so I’ve been steeped in all sort of insulation materials, including some oddball products. One of those is vacuum insulation — the principle of a Thermos bottle.In theory, vacuum insulation is a great idea. To understand why, it helps to know a bit about heat flow.

Using a vacuum to insulate more than our coffeeIf a vacuum works so well to keep our coffee hot all day, why not use one to insulate our houses? Vacuum insulation panels have been used to insulate some high-tech demonstration homes, such as entrants in the Solar Decathlon student design competition in recent years, but high cost makes them impractical for real buildings.There’s also the problem that puncturing that vacuum insulation panel will significantly reduce its insulating performance. (I can imagine how bummed one would be after spending thousands to insulate a home with vacuum insulation panels and then hearing a hiss while hanging a painting!)However, these vacuum insulation panels (sometimes called VIPs) could make a great deal of sense in certain value-added products like refrigerators, freezers, water heaters, and entry doors. Whirlpool actually used a VIP that Owens Corning produced for a while (the Aura panel) in a high-efficiency refrigerator in the mid-1990s, but then dropped both the refrigerator and the use of VIPs.But I believe the benefits of R-25 or more in a one-inch-thick panel are significant enough — especially as we try to get more usable volume in refrigerators without growing the exterior dimensions — to warrant the embrace of vacuum insulation. These could also be a great solution for exterior doors that are notoriously poorly insulated — as I’ve written about in this blog.There are at least a half-dozen manufacturers of vacuum insulation panels today. Most, including Microtherm and Nanopore, produce panels that have a rigid, porous substrate surrounded by an impermeable metal skin. A new VIP on the marketThe latest VIP to come along is made by Dow Corning (no relation to Owens Corning). This panel, not yet widely available, is one inch thick and has a center-of-panel insulating value of R-39 and a “unit R-value” (accounting for the edges) of R-30, according to the company.The Dow Corning product has a core made of fumed silica cake, a remarkable “microporous” material that provides R-8 per inch even without a vacuum. This material allows a very high insulating value even with a softer vacuum. The core is reinforced with silicon carbide and polyester fibers for structural support, and it is encased in an inner layer of polyethylene and an outer layer of polyethylene, polyester, and aluminum. The panels are vacuum-sealed, and the edges are heat-sealed.According to an Environmental Building News article, these Dow Corning panels should cost $10-12 per square foot. At that cost, I believe VIPs can be very practical for those appliance and exterior door applications noted above.center_img How a vacuum slows down heat transferThere are three modes of heat transfer: conduction, convection, and radiation, and if we remove most of the air molecules from a space — as occurs when we draw a vacuum — we largely eliminate the first two of those heat transfer mechanisms.Conduction is the flow of heat from molecule to molecule. It’s the reason a cast-iron skillet handle heats up. But thermal conduction also occurs across a layer of air, as kinetic is transferred from one air molecule to the one next to it. If we remove most of those air molecules by creating a vacuum, there will far less conductive heat flow. RELATED ARTICLES A Few Product Highlights from GreenBuildGBA Product Guide: Dow Corning Vacuum Insulation Panels Vacuum Insulation Panel The “hardness” of a vacuumThe key property of a vacuum is its pressure, or how “hard” it is. We often measure that with Torr units. One Torr is exactly 1/760th of a standard atmosphere (1.3 x 10-3 atm), or approximately 1 mm of mercury. With a very hard vacuum, more of the air molecules are sucked out, resulting a greater negative pressure. The walls of a typical Stanley Thermos bottle contain a relatively hard vacuum of 10-6 Torr. With such a hard vacuum, that Thermos bottle can keep coffee hot all day. By comparison, the vacuum in a flat vacuum insulation panel is typically no more than 1/1000th as strong (10-3 Torr).The harder the vacuum, the more difficult it is to maintain it. Thermos bottles are made with a cylindrical design for optimal strength. With flat panels, it’s very hard to achieve comparable strength and maintain such a hard vacuum, particularly at the edges.last_img read more

Corruption, reservation stall proceedings in Council for second day

first_imgThe Council was adjourned for the second consecutive day on Friday over State government’s “failure” to give reservation for the Dhangar (shepherd) community, and address the issue of corruption by Cabinet ministers. Like Thursday, the House was adjourned three times before continuous pandemonium forced the chairman to call off the proceedings for the day prior to lunch time. Leader of the Opposition Dhananjay Munde claimed that the Opposition had ‘conclusive evidence’ against 16 ministers of the BJP-Shiv Sena government and the treasury benches were causing commotion only to avoid a debate. “This Government is trying to protect the corrupt. This has been the policy of this government, and we condemn their casual approach to such a serious issue,” he said. The Opposition MLCs said the government has broken away from the traditions of the august house by evading important debates brought up under the Legislative Rules. “This Government has broken away from the tradition by not allowing the dissenting voices to put across a point of public interest,” said Bhai Jagtap (Congress). ‘Sena behind downfall of Marathi’ Members of the Opposition on Friday blamed the Shiv Sena for the downfall of the Marathi language, alleging that the party when in power had not done enough to preserve the language. Speaking in the Council over the proposal for grant of classical status to Marathi language and issues related to its conservation, Kapil Patil of the Lok Bharati Party said, “The Sena despite being in power for so many years has not done enough. It even enters agreement with its staff and members in English, and then claims to be a saviour of the language in public.” He also demanded at least 50 % subsidy for Marathi medium schools.last_img read more

Formula One: Sauber F1 team changes name to Alfa Romeo Racing

first_imgThe Sauber name will disappear from the Formula One grid this season after the Swiss-based team announced on Friday it had been renamed Alfa Romeo Racing as part of an extended sponsorship deal.The team, who finished eighth out of 10 in the constructors’ championship last year, will remain under the same independent ownership and management with Frenchman Frederic Vasseur as principal.Sauber made their Formula One debut as a privately-owned team in 1993, taking their sole victory at the 2008 Canadian Grand Prix while racing as BMW’s factory team.They have been partnered by Fiat Chrysler brand Alfa Romeo since last year.New name, same game! We’re excited to announce Sauber and Alfa Romeo to keep fighting for ambitious results in 2019 @F1 World Championship as Alfa Romeo Racing. + info: #AlfaRomeoRacing #SauberMotorsport #Bwoah Romeo Racing (@SauberF1Team) February 1, 2019The team use the same engines as Ferrari, with whom they have close ties, and have Finland’s 2007 world champion Kimi Raikkonen and Italian Antonio Giovinazzi in an all-new driver lineup for 2019.Alfa Romeo has a strong heritage in Formula One with the first two world championships in 1950 and 1951 won by Italian Giuseppe “Nino” Farina and Argentine Juan Manuel Fangio in cars carrying the four-leaf clover emblem.Ferrari’s late founder Enzo also started out racing and managing a team for Alfa Romeo, before setting up on his own in the late 1930s.Founded in 1910, Alfa Romeo supplied Formula One engines in the 1960s and 1970s and returned as a constructor in 1979 before again withdrawing at the end of 1985.advertisementAlso Read | Mick Schumacher follows in father Michael’s footsteps, joins Ferrari Driver AcademyAlso Read | Force India renamed to Racing Point F1, Lance Stroll comes on board for 2019 seasonlast_img read more

Dukes Lehigh Loss Was Bad But Mercer Was Worser

Some upsets aren’t as big as the seed lines suggest; some are bigger. Two years ago, the No. 2-seeded Duke Blue Devils were upset by No. 15 Lehigh in the first round of the NCAA tournament. But Duke was the weakest No. 2 seed in 2012, according to the FiveThirtyEight projections that year, whereas Lehigh was unusually strong for a No. 15. Our model had given Lehigh a 10 percent chance of winning.Something of the same pattern held last season when No. 2 Georgetown lost to No. 15 Florida Gulf Coast in the first round. Georgetown was just the 15th-best team in the country, according to our ratings, and was badly overseeded as a No. 2. Our model gave that upset a 10 percent chance of occurring as well.This afternoon, as a No. 3 seed, Duke lost to 14th-seeded Mercer — but the Blue Devils (and the FiveThirtyEight model) have fewer excuses. In fact, Duke was the strongest No. 3 by some margin this year, according to our ratings and other indices like Ken Pomeroy’s power ratings. Our projections had Mercer with just a 7 percent chance of winning before the game began. read more
