Air quality unlikely to improve amid Western wildfires: scientists

PORTLAND, Ore. — Relief from putrid, dangerous air spewing from massive wildfires across the West won’t come until later in the week or beyond, scientists and forecasters say, and the hazy and gunk-filled skies might stick around for even longer. People in Oregon, Washington and parts of California were struggling under acrid yellowish-green smog — the worst, most unhealthy air on the planet according to some measurements. It seeped into homes and businesses, sneaked into cars through air conditioning vents and caused the closure of iconic locations such as Powell’s Books and the Oregon Zoo in Portland, the state’s biggest city. “I don’t think that we should be outside, but at the same time, we’ve been cooped up in the house already for months so it’s kind of hard to dictate what’s ...

Wabtec begins trial of environmentally friendly air conditioning system

Wabtec has begun trials of the transit rail industry’s first air conditioning system using natural R290 refrigerant, a clean and environmentally friendly option. This Wabtec Green Air technology is part of the company’s initiative to bring clean, sustainable solutions to the transit market. “Transit authorities continually look for opportunities to reduce the carbon footprint of their operations,” said Lilian Leroux, president of Wabtec’s Transit business. “Traditional synthetic refrigerants provide a cool, comfortable environment for passengers, but those options are not healthy for the environment.” The refrigerant R290 used in the Green Air system has a Global Warming Potential (GWP) of three. Traditional heating, ventilation and air-conditioning systems use synthetic refrigera...

Fresno unveils homeless shelter units to replace aging ones. These have air conditioning

The Poverello House in southwest Fresno on Wednesday unveiled new homeless housing that is roomier, temperature controlled and can serve more people than its almost 20-year-old digs, according to officials. Load Error The 30 new pallet shelters are about 100 square feet, come with heating and air conditioning, and are hooked up to provide electricity to their tenants, according to Poverello House officials. “They look good, they look sturdy and most importantly they offer the conveniences that make life more comfortable,” Mayor Lee Brand said. “We’ve neglected the homeless housing problem for far too long.” The new shelters, which continue to go up Wednesday, replace 64-square-foot Tuff Shed brand shelters that had no temperature control or electrical outlets and have been in use ...

Slow improvement on wildfire front; air quality alert extended to Thursday

A week after wildfires began consuming thousands of acres in western Oregon, firefighters are making progress on some of the most destructive blazes in state history. State officials said Monday that 10 people have died, though that number was higher than the totals released by county officials, and 22 are still missing. Countless homes and businesses have been scorched.Much of the state remains under an air quality alert that has been extended until noon on Thursday, as winds forecasters were expecting didn’t materialize.Rebecca Muessle with the National Weather Service’s Portland office said that the thick smoke blanketing the west coast has made winds harder to predict, since they’ve stopped the warming afternoon temperatures that can create windy conditions.“We do have a system moving ...

Can indoor air filtration protect you against COVID-19? Maybe | Local News

MERIDIAN — Like many other business owners in the Treasure Valley, J.P. Green decided he needed to make changes to reopen his business this spring, after he was legally able to do so, following historic closures meant to slow the spread of the new coronavirus.He owns and operates CycleBar Village Meridian, a studio that offers stationary bike classes. The risk of the spread of the virus was there, he knew, but he was legally able to open the business again in May. He took precautions: smaller class sizes, a contactless check-in process, a 30-minute window between each class for deep cleaning.Green said he wanted to go further in making the studio safe for customers and staff, so installed the REME HALO, an air purification device that attaches to the studio...

Broken air conditioner delays Bricolage Academy students’ return to campus

Bricolage Academy has delayed the start of in-person learning several days due to a heating, venting and cooling system issue — rooted in one air conditioning unit that cools several classrooms — district and school officials confirmed Friday.  The school had been scheduled to reopen to students on Monday. It will now open on Thursday instead.  “Unfortunately, our Heating, Ventilation, and Air Conditioning (HVAC) system is performing inconsistently and several classrooms have experienced outages,” Bricolage CEO Troave’ Profice wrote in an email to parents Thursday night. “We were informed this afternoon that while the required parts have been ordered, they will not arrive until early next week.”The email did not elaborate on what the problem was. But Profice and a spokesperso...

Prevent wildfire smoke from entering your home: It’s OK to run air conditioners

Deadly wildfires in Oregon and Washington are taking lives, destroying property and making the air dangerous to breathe.Health experts are advising all residents to stay indoors unless absolutely necessary. Most non-medical grade masks won’t protect lungs from the fine particulates of wildfire smoke.The National Weather Service has issued an air quality advisory for most of the western, central and southern parts of Oregon and Southwest Washington.Conditions in Portland, which has the worst air quality of any major city, could improve on Monday, according to the National Weather Service. Until then, smoke, which is a mixture of air pollutants, and dense fog are thick enough to block out the view of the sun, but not the heat.“The biggest question we have been getting is, ‘Should I run my ai...

Custom truck paint job with Auto Air Colors, LMC Truck on 2003 Chevy Silverado overland build

When we left off last month, we had installed the SnugTop shell and giant Yakima rack, and we were pretty much out of things to do except tear the truck down for paint, so we can bolt on all the cool parts we've been collecting. Behind the scenes, we've slowly been taking care of the prep for paint, first by getting rid of all the stock trim, then roughing out the really bad spots on our junkyard bed and tailgate with some rudimentary metal shaping and filler work. Then we found a reasonable body man for hire who knocked out the rest of the bad spots for us. From there, we spot-primered the whole truck, then gave it a wet sand with 220-grit sandpaper. We did it all again with 400-grit then finally attached the new HD hood from LMC Truck and hit the road for LGE-CTS.While this quick and dir...

How to avoid the coming air conditioning crunch

As record-breaking heat waves baked Californians last month, the collective strain of millions of air conditioners forced the state’s grid operators to plunge hundreds of thousands of households into darkness. The rolling blackouts offered just a small hint of what’s likely to come in California and far beyond. Growing populations, rising incomes, increasing urbanization, and climbing summer temperatures could triple the number of AC units installed worldwide by midcentury, pushing the total toward 6 billion, according to the International Energy Agency’s Future of Cooling report. Indeed, air conditioning represents one of the most insidious challenges of climate change, and one of the most difficult technological problems to fix. The more the world warms, the more we’ll need cooling—not...

Warmed Tunnel Air Provides Heating/Cooling Energy

Researchers at EPFL have calculated the benefits of a geothermal heat recovery system, using fluid-filled plastic pipes, for train tunnels. (Image source:  LMS / 2019 EPFL)Turning waste energy into useful work is becoming a trend. Now, researchers at Ecole Polytechnique Fédérale de Lausanne (EPFL), a research institute in Switzerland, have proposed a way to capture the wasted heat energy in rail tunnels to provide heating and cooling to thousands of homes and municipal buildings.Trains produce heat that warms the surrounding air when they brake or accelerate. That hot air mixes with other air in the tunnel and with heat radiating from the ground. Even the body heat from the passengers adds to the overall heat energy that is pre...

Air circulation and coronavirus: How to judge a ventilation system

Stagnant, poorly circulated air could foster coronavirus transmission in some indoor spaces.But it can be hard to tell whether a building's heating, ventilation, and air conditioning (HVAC) system is working properly to minimize risk.Two HVAC experts offer tips on how to spot low-quality systems.Visit Business Insider's homepage for more stories. Imagine coronavirus particles in a space like glitter in a pool: The glitter is the virus, while the water is the air. That's how Theresa Pistochini, an engineer specializing in heating, ventilation, and air conditioning (HVAC) systems, likes to visualize it. To get glitter out of a pool, a system should have three main components: it must move water around (circulation), remove glitter from the circulating water (filtrat...

Rethinking indoor air to stop the spread of COVID-19

As we learn more about how COVID-19 spreads, it’s clear that air flow is a big deal, and that’s why masks are effective at slowing infection. That’s a problem for offices and commercial buildings and some homes because over the last couple of decades buildings have less ventilation. Instead, they recirculate air to save energy by not letting that cooled or heated air escape. But these buildings also end up recirculating viruses, especially if heating and cooling systems aren’t paired with really good filters that remove viral particles from the air.  I spoke with Jeffrey Siegel, a professor of engineering at the University of Toronto who specializes in indoor air quality. He says it’s a great time to talk about all of this. The following is an edited transcript of our conv...

Why Louisiana air conditioning business are feeling the heat more than usual this summer | Business

Here’s another industry being disrupted by the coronavirus pandemic: air conditioning sales and repair.Local air conditioning repair companies in Baton Rouge, New Orleans and Lafayette said they are seeing a shortage of parts and equipment, which was caused by manufacturing facilities in Mexico and China being shut down by the pandemic. At the same time, demand for air conditioning in other parts of the U.S. has gone up because people are spending more time at home and want to be comfortable.Daniel Bandy, owner of Aire Serv of south Baton Rouge, said parts that used to take a day or two to get are now arriving in a week or 10 days.“It’s not one supplier that had a time frame change, it’s all of them,” he said. “Trane, Lennox, Carrier have all had issues.”Ai...

What You Need to Know About Air Filters

There is still much we don’t know about HVAC and COVID-19 transmission, but HVAC best practices may reduce the risk of transmission somewhat, according to two statements by ASHRAE. ASHRAE’s statement on the airborne transmission of SARS-CoV-2, the virus that causes COVID-19, concluded, “Transmission of SARS-CoV-2 through the air is sufficiently likely that airborne exposure to the virus should be controlled. Changes to building operations, including the operation of heating, ventilating and air-conditioning systems, can reduce airborne exposures.” The organization also released an HVAC-specific statement: “Ventilation and filtration provided by heating, ventilating and air-conditioning systems can reduce the airborne concentration of SARS-CoV-2 and thus the risk of transmission through t...

Local HVAC Company Stresses The Importance of Proper Air Filtration During COVID-19 – Press Release

The pandemic has more than just a few people scrambling and looking for answers. Schools are beginning to reopen, and more than one has already shuttered its doors because of contact with people with the COVID-19 virus. While it is difficult to protect a family and loved ones in public even with personal protective equipment, it would make sense that the home would be one place where safety is all but guaranteed. Those living with someone with the COVID-19 virus are certainly taking as many precautions as feasible, including necessary social distancing, hygiene and sanitation. However, there is one part of the home that is often overlooked and could be a helpful ally in the fight against having the virus spread. The home HVAC system does much more than simply heat and cool a home. T...
