GM set the tone with greener air conditioning systems

Monday, July 26th, 2010, by Richard Salmon

air-conGM are keen to promote their greenhouse gas-friendly air conditioning unit in a bid to overcome the bad PR that surrounded their bailout by the US and Canadian Governments.

Any car purchased before the 1990’s was installed with a air conditioning unit most likely powered by Freon (R-12). The company were ideal in giving drivers a comfortable environment and even better at releasing greenhouse gases that were harmful to the ozone layer. So in the mid 1990’s GM’s switched to a less harmful R-134a.

The R-134a quickly became more popular but still emits greenhouse gases into the envrionment that don’t break down very quickly. The refirgerant has an atmospheric life of more than 13 years which gives it a global warming potential (GWP) rating over 1,400.

So through a partnership with Honeywell the new GM air conditioning unit will use HFO-1234yf a chemical that breaks down much faster in the air than a R134a. And instead of 13 years the chemical breaks down in 11 days making the GWP 4, which is 99.7 per cent lower than R-134a.

The greener air conditioning system will be used in 2013 editions of the Chevrolet, Buick, GMC and Cadillac models in the US. The new air con system will not only hit EPA’s new motor vehicle greenhouse gas regulations for 2016, but it will also set the standards for car companies around the globe.

1 in 20 Air Conditioners Not Meeting Required Standards

Tuesday, June 8th, 2010, by admin

According to research by the CIBSE (Chartered Institute of Building Services Engineers), a staggering 1 in 20 air conditioning units inspected by officials are failing to meet the required standards.

The CIBSE are leading a campaign to force the new Government to tackle the woeful level of compliance and to ensure air conditioning units run efficiently. Their campaign is backed by the UK Green Building Council, BRE Global, the Heating and Ventilating Contractors’ Association and the British Institute of Facilities Management and has already got the support of over 300 industry signatories – and of course, everyone here at Airconco.

Non-compliance with the Energy Performance in Buildings regs and the F-Gas regs is at an all-time low and the campaign argues that this is costing both the industry and the environment and an air conditioning service overhaul throughout the country is necessary.

CIBSE President Elect Rob Manning said: “The campaign aims to bring together the many voices of frustration and concern to form one united call for action. We need to raise the issue of non-compliance up the government agenda and promote the benefits of increasing compliance rates.

“Non-compliance has real costs; it costs the environment, it will cost the UK any chance of meeting the emissions targets and it costs non complying companies who are missing out on a real opportunity to increase their profits.”

How To Avoid The Dreaded Sneeze At The Wheel

Monday, June 7th, 2010, by Richard Salmon

Is there anything scarier than sneezing at the wheel? Think about it; you’re travelling at 30mph, 40mph, 70mph, wherever you may be – and for a couple of seconds you totally blank out, effectively driving blindfolded. And that’s not including the dreaded double sneeze! By the time you regain your composure, you realise you’re careering towards the car in front or drifting across the next lane – it can be a fairly harrowing experience.

In fact, in excess of 2 million UK motorists (7 per cent) have had an accident, near miss, or momentarily lost control of their car as a result of sneezing while driving, whilst almost 60% have, at some point, looked away from the road to search for a tissue. But did you know that air conditioning can help?

According to Kwik-Fit, a car’s air conditioning system can provide a defence against pollen, but to be effective the system needs an air conditioning service regularly and the pollen filter changed at least once a year, even more so if the car is often parked under trees.

“All too often, air conditioning units are ignored from one summer to the next,” says David White, customer services director at Kwik-Fit, “But air-con is most efficient if it’s used frequently and serviced regularly.

“As the weather gets warmer, motorists quickly realise that their air-con isn’t functioning as well as it could. But if you’re a hay fever sufferer with a fit of the sneezes, the incentive to have your system serviced is even greater – the benefits aren’t to be sniffed at.”

Knoxville Rarities Damaged By Malfunctioning Air Conditioner

Wednesday, May 5th, 2010, by Richard Salmon

One of Knoxville’s most important historical libraries – the Calvin M. McClung Collection – suffered water damage earlier this week, as air conditioners and humidifier systems leaked into the building’s storage areas. Approximately 200 books were damaged by the leak, with visibly ruined covers and dampened text reasonably common. Rare Book Collection Interior 6 by UBC Library Graphics.

While officials were upset by the extent of the damage, they were optimistic about the books’ recovery efforts. Water damage to most of the texts was relatively limited, with most books able to be restored and recovered by local experts.

Employees and volunteers were within the affected rooms within hours, those on the scene report, handling the texts and ensuring that they weren’t further damaged. Keeping in line with standard procedure for damaged books, all affected copies were wrapped up and placed in a freezer – designed to prevent further damage to the moist pages.

While the point of fault has been located – a humidifier in the building’s public storage area – it’s prompted more than just a swift replacement. Officials are investing in a new humidity and air conditioning service system for the building, designed to keep the books at an ideal temperature and free or risk.

Airlines Concerned About Volcanic Ash in Air Conditioning Systems

Friday, April 30th, 2010, by Richard Salmon

Europe’s airports have been troubled by Icelandic volcanic ash for the past three weeks. While a growing number of airports are reopening and accepting passengers, many are boarding flights hesitantly, concerned about the potential health problems caused by ash and dust caught in air conditioning systems.

Allergies, reactions, and ill-effects caused by airplane air conditioning are relatively common, with many passengers experiencing dry breathing passages or a common cold during their holiday. Most aircraft air conditioners are fitted with large filtration systems, ensuring the ash and grit won’t pass through into the cabin, but a number of passengers are still concerned. Air New Zealand by Fly For Fun.

The potential risks don’t seem to be limited to those inside the cabin, either. Pilots are concerned about emergency landings which could be caused by the ash. As grit and dust enters the plane’s air conditioning system – a system also responsible for regulating cabin air pressure – pilots may be required to switch air conditioning off to ensure passengers are kept safe.

While relatively inconsequential for local flights, international flights and long-haul carriers may need to land in order to clear out the dust and carry out air conditioning maintenance. With many British air travellers still stranded overseas, news of health risks from airlines certainly aren’t coming as welcome news.

6 Devastating Heat Waves and Bizarre Weather Events (Part One)

Wednesday, April 28th, 2010, by Richard Salmon

Ever wake up, get dressed, and step out the door to be greeted with a wave of ultra-hot air? Whether you’re located in the tropics or the subarctic, there’s little doubt you’ve felt that burst of warm air as you stepped outside of your home, mostly during the middle of summer. For some cities, it’s a near-blanket of tropical humidity and misty – a high-30s heat wave that forces you inside with the air conditioning cranked up.

For other cities, it’s a dry, arid heat – the type of temperature that makes concentration impossible and physical exertion a dream. Whether you fight it with a cool drink or a day huddled in front of the air conditioner is anyone’s guess – these days aren’t comfortable, and there’s no doubt about it.

We’ve found six truly devastating heat waves and hot weather events, each located in a different part of the world. From Chicago to Shanghai; Melbourne to Buenos Aires, these six heat waves brought sudden heat, devastating commercial effects, and potentially lethal disruption to the globe. Fans of a good old air conditioning service best close their eyes, but tanning gurus and hot weather fanatics will love these extreme heat waves.

1. The 2003 French Heat Wave

France’s 2003 heat wave was one of the most economically and socially devastating events in recent history. With almost the entire European continent affected by record temperatures and severe drought, a number of crop failures and agricultural setbacks pushed South and Central Europe’s countries into a spin.

However, few countries were hurt more than France. With over 30,000 deaths throughout Europe and multi-billion dollar financial damage, the heat wave’s epicenter was located directly above France’s central region. Temperatures were dangerously high from Paris all the way to Marseilles, with some cities experiencing heat well above 40ºC – a major change from France’s relatively temperate central conditions.

2. The Great Depression ‘Dust Bowl’ Years

The 1930s weren’t a great time to be American. There was the Great Depression – a sever economic downturn in the wake of some short-sighted financial decisions. There was also the ultra-cold winter of 1935 – one of the coldest and most disruptive on record. Finally, there was the the North American heat wave – one of the most extreme climate events in history, and a major source of health and financial woes at one of the United States’ worst points.

Piece it all together and you’re left with a fairly nasty decade. Unfortunately, the 1930s weren’t the best decade to experience a heat wave – air conditioning had yet to be invented, and due to the ongoing depression, most public buildings had severely reduced service and operating budgets. Besides sweating it out 24/7, most of the United States’ population were struggling to piece things together financially.

3. Southeast Australia’s Six-Day Fire and Sun Wave

Australia’s international reputation may paint it as the ‘warm’ continent, but in reality its southern corners can see some pretty extreme cool points during the year. From Melbourne to Adelaide; Hobart to ACT, Australia’s southern points experience a cool winter and relatively Spartan summer temperatures, with daytime temperatures rarely exceeding 30ºC.

It’s amazing then, that the region’s temperatures saw such a surge in early 2009. Record high temperatures – well above 40ºC in some cities, and over 46ºC in Melbourne – saw the giant country’s southern areas turn into an arid desert overnight. Following severe fires in the area surrounding Melbourne, the state of Victoria was put under alert – residents sat inside their houses watching the sky fill with drifting smoke.

Toyota’s New Solar Air Conditioned Prius

Friday, March 26th, 2010, by Richard Salmon

Fans of green technology and cool air are in for a surprise when they look inside Toyota’s new 2010 Prius. The new hybrid car comes equipped with a full solar power panel for its air conditioning and in-car entertainment system. In a move towards total green energy, Toyota have stripped away the standard power-hungry air conditioner and replaced it with one that’s closer to a solar cooling system than the gas-sucking system most people know.

It’s said that in most cars, just 15% of used gasoline makes it to the wheels. This alarming statistic is, in most cases, quite true. Air conditioning services, entertainment systems, engine control computers and lights each require a large amount of energy, most of which is generated through burning gasoline. 2010 Toyota Prius by alex4981.

Toyota certainly aren’t the first company to embrace solar air conditioning, although they are the first auto manufacturer to use the technology. A number of office buildings have made use of solar energy for their cool air systems, including the American Apparel factory and management building in Los Angeles.

‘Green conscience’ affects thousands of consumers annually, a spending trend backed up by strong sales of hybrid cars and power-saving equipment. Home air conditioners have been optimized to the point of impressive energy efficiency, however many automobile systems still lag behind in energy usage. While Toyota’s solution certainly doesn’t cut down on all energy usage, it’s a clear step in the right direction.

3 Ways to Keep Your Car Cool Without Air Conditioning

Wednesday, March 24th, 2010, by Richard Salmon

Every driver has experienced the ‘car oven’ phenomenon. You set off to work on a warm day only to realise that your low-end car lacks air conditioning. Next time you find yourself caught out in an ageing or low-cost automobile, don’t despair. Now, off course we’re total buffs when it comes to air conditioning but although it’s mightily important on a grand scale, it isn’t actually the be-all and end-all. These three tactics can help you keep the car cool, crisp, and comfortable for your commute or long distance journey.

1. Crack your windows, and crank up the fan Inside the New Car by Chris Campbell.

Fan systems are most effective when combined with a source of fresh, cool air. For most car owners, that means a slightly opened window. Don’t open it all the way if it’s warm outside – just crack the window and let a small amount of fresh air enter the car.

2. Store ice in the car

Unfortunately, it’s not quite as easy as popping down to the supermarket and dumping ice cubes in the car. By storing a container full of ice next to your car’s ventilation system, you’ll be able to cool and humidify the air without worrying about excess gas usage. This old-fashioned air conditioning method was popular in Arizona in the mid 20th century.

3. Apply window tints

Tinted windows don’t actively cool your car, but they do cut down on the amount of sunlight that can enter. By decreasing the transparency of your windows, you’ll let less light enter the car and quickly lower the overall temperature. Be careful – some country’s ban tinted windows, or apply limits to the transparency level of the glass.

And no air conditioning maintenance costs going forward…

The World’s Hottest Cities – 3 Destinations Where Air Conditioning is a Must

Thursday, March 18th, 2010, by Richard Salmon

Need to travel to somewhere hot? If the winter cold spell is getting you down, a quick trip to one of these tropical hot-spots could be just what’s needed. However, you’d better be comfortable with an air conditioner – with highs of almost 40 degrees Celsius, a holiday in one of these destinations could get painful quickly.

Before you step off the plane into any of these three cities, make absolutely sure your hotel’s got a good air conditioning service:

1. Bangkok, Thailand Bangkok Skyline by Mobile First.

The Thai capital may not be the hottest place on earth, but it does have the highest average annual temperature. With highs well into the high 30s coupled with the occasional 40 degree day, this tropical megalopolis doesn’t quite touch deadly heat, but it certainly does verge on uncomfortable.

2. Jizan, Saudi Arabia

Jizan isn’t the hottest place on earth (an honour that goes to California’s Death Valley) but it is one of the most consistently hot. This small city in western Saudi Arabia is closer to tropical than desert steppe, although it does experience the occasional dry month.

3. Wyndham, Australia

Wyndham certainly isn’t the place to go for relaxing summer temperatures. Despite being situated in tropical Western Australia, the small town rarely experiences temperatures below 30 degrees. Highs touch on 40 quite regularly, making Wyndham a pretty nasty place for cool weather fans.

US Researchers Aim to Improve Air Conditioning Efficiency

Tuesday, March 16th, 2010, by Richard Salmon

A team of researchers from the Palo Alto Research Center have been hard at work on a new thermoacoustic cooling technology that could reduce air conditioning power usage by 50%. With a prototype currently in production and plans to have the technology ready for the market within the next few years, the researchers hope to eliminate upwards of 10% of the United States’ energy usage.

Air conditioning maintenance account for approximately 25% of home energy usage, a figure that’s made up primarily of air conditioning systems in the ultra-hot Southern states. South-western states such as California, Nevada, and Arizona are known for their extreme temperatures, with daytime heat regularly exceeding 110 degrees Fahrenheit.

With standard air conditioning systems only approaching 12% total efficiency, the new technology could be a much-needed boost to systems’ value. With the recession still affecting employment and income for many families, a large amount of people are cutting down on air conditioning usage to escape a high power bill.

However, while air conditioning is often seen as a major expense, it’s rare to find inefficient modern units. The majority of air conditioning complaints come from those with ageing air conditioning installations, or households that operate their systems inefficiently.

Even so, any developments towards greater energy efficiency are great progress. The United States currently generates upwards of 600 million tons of carbon dioxide. The Palo Alto Research Center aim to use their technology for reducing carbon usage, with targets of under 300 million tons per year.
