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.

Nursing home fined after air conditioning failure

A nursing home in Baltimore, America has been fined $52,500 in state fines over air conditioning failures which forced the transfer of 150 patients from the facility.

The Ravenwood Nursing & Rehabilitation Centre – who have risked losing its licence – had air conditioning pumps and compressors that had been inoperable since last summer, with blowers and filters in patients’ rooms dirty and clogged.

The state Office of Health Care Quality found that on July 2 the centres chilled circulation pumps had failed and the temperatures of the patient care floors had begun rising, reaching 90-96 degrees by the time state inspectors arrived on July 6th. One of the West Franklin Street centre patients had to be treated for heat-related dehydration at a local hospital.

The home’s walk-in refrigerator was found with the door propped open with a food cart to help cool the kitchen down. Due to this, fridge temperatures had climbed to 60 degree. Safe temperature for food storage is 41 degrees.

“The chronic problem we saw was a failure to maintain a cooling system that could withstand the heat that was predicted that week,” said Nancy Grimm, director of the Office of Health Care Quality. “The acute problem was a failure to communicate and respond to the loss of the air conditioning” before it became a crisis, she said. “There may be some financial issues as well, which we’re working through right now.”

Chief Operating Officer of Ravenwood Healthcare Inc, Michael D. Smith, issued a statement expressing gratitude to the state and the city for full assistance with what he called  “our recent voluntary evacuation of our facility following unexpected air conditioning problems.”

The state’s report “reflects some needed work” on the air conditioning system, Smith said, but it “actually only became inoperable on [July 4]…It is unfortunate that the system could not be immediately repaired once inoperable.”

However the state’s investigation found that Ravenwood’s managers were aware about the breakdowns in the air conditioning for more than a year, failed to take timely, effective action to avoid a complete failire, and did notify the Department of Health and Mental Hygiene of their problem.

Grim said that Ravenwood did nothing to get people out saying, “They didn’t do anything to ensure or suggest that. So we said, ‘We’ve got to get these people out of here.’ And they agreed to it.”

“The outcome of these problems together is that 150 residents were abruptly uprooted from their home, family and belongings, and they had little control over the situation, which we found to be a psychosocial harm to the patients,” Grimm said.

At present the nursing home is empty and the $52,500 has been ordered to a draft plan of correction in 10 days. Ravenwood have three months to achieve ’substantial compliance’ with state and federal standards of care.

The Department of Health and Mental Hygiene will recommend that Ravenwood will be denied Medicare or Medicaid payments for new admissions if the home is not in substantial compliance by October 16th.

Patients will not return to the facility until it is reinspected.

Smith, Ravenwood’s COO, said the air-conditioning system has been repaired and inspected. “All the units are running and cooling the facility,” he said. “We are currently working with [the Office of Health Care Quality] and hope to begin returning residents to their home within the next several days following a revisit by their office.”

Authorities were made aware of the situation after a patient called 911 complaining that the building was too hot and ‘he wasn’t able to breathe’ on July 6th according to the state’s report.

When paramedics arrived Ravenwood personnel began to move patients to an area of the building with working air conditioning and portable air conditioning was brought in.

Air Conditioning Hero Helps the Homeless

Friday, July 2nd, 2010, by Richard Salmon

A shining knight has come to the rescue of a homeless shelter in the US after he’d heard that thieves had stolen the shelter’s five air conditioning units.

Monty Weeks, owner and vice president of Weeks Service, showed up at the Turning Point Center last Wednesday with five replacement units in tow to restore a cooling, comfortable temperature in what is now the hottest period in the USA’s summer.

“It’s a shame that happened,” Weeks said. “We just wanted to get that turned around for them as soon as possible.”

“It’s a way of giving back, it’s just part of what we do,” Weeks said. “Those people were in need, and that was a need we could fill, so we did it as soon as we could.”

Houston police continue to investigate the theft. The units cooled the building where clients attended classes on programs such as anger management, continuing education and social and life skills.

With the air conditioning working again, residents were back in the building for their classes within 24 hours.

“It was so gratifying and kind,” director George Gomez said. “They didn’t want any recognition. You can’t help but be moved.”

“It restores your faith in humanity. We get a lot of criticism as Americans, but we live in the best country in the world. The goodness of these people outweighs the bad. You just don’t hear much about the good things that happen.”

Portable Air Conditioning of the 21st Century

Monday, June 28th, 2010, by Richard Salmon

It’s that time of the year – lobster-red Brits are out in force in vest tops and cut-offs galore whilst foreign newcomers to our shores walk around in bemusement with scarves and three layers.

But more fool them – it’s time to embrace the rare sun that we have and, of course, keep cool while doing so. To their credit, Dyson have designed a funky product that does just that – showing that contemporary portable air conditioning is alive and well. dyson-fan-cool-001

The brand, renowned for their vacuum cleaners, launched a series of bladeless fans several months ago to provide a greener option in the air conditioning sector and a safer version of the traditional fan. It claims its specially developed technology generates a smooth, uninterrupted airflow without the buffeting of blade fans.

The bladeless Dyson air conditioning units have now become one of the UK’s hot sellers alongside barbecues and sun tan lotion.

With over 100 patents pending, the technology inside Dyson’s bladeless fans works by sucking up to 33 litres of air into the cyclone accelerator, in a similar way to a jet-engine or a turbo-charger in a car.

M&S reported a 300% surge in sales of the product as temperatures soared whilst a YouTube video showing the fan’s features has been inundated by fascinated fans, gaining over half a million hits.

Djokovic Beats Air Conditioning To Claim 11th Hour Win

Wednesday, June 23rd, 2010, by Richard Salmon

Serbian tennis star Nenad Djokovic sealed a dramatic late victory in the latest match ever to take place at Wimbledon with just two minutes left on the clock.

Tennis matches aren’t traditionally up against the clock but as the night draws in and those in close proximity to Wimbledon put their heads down, all action at SW19 must come to an abrupt halt to ensure those around aren’t disturbed. The main reason stipulated by Wimbledon officials is down to air conditioning.

The rules state that play must finish no later than 11pm after the issue of a special licence by the local council designed to minimise noise problems for residents. Generators that power the special air conditioning system, which prevent condensation forming on the roof and dripping on to the grass, can be heard outside the grounds. There is also the issue of getting thousands of fans away from the grounds on public transport late at night along with hundreds of cars leaving the area.

At 10:58pm, with the match two minutes away from the deadline of having to come back the next day, Djokovic finally prevailed in a marathon five-set match against the Belgian Olivier Rocchus.

Djokovic admitted he was fortunate to go through. The Serbian said: “I had a big challenge with myself in this match and only showed my real game in the final two sets.

“I had a big struggle against Olivier and the break for the roof to be closed was good for me. It helped me to focus and reset my game.

“It was interesting to have a late night match at Wimbledon. I am happy my name is in the history books. It was very humid out there and it’s different conditions.”

Air Con in the Car – What’s the Deal?

Wednesday, June 16th, 2010, by Richard Salmon

The sun’s out, the shades are donned, and the A/C is is turned up to the max – instantly we’re feeling cooler – but at what cost?

There are plenty of myths and half-truths doing the rounds about how your vehicle’s resources are drained by aircon – so what’s the actual deal here?

The truth is this; the air conditioning in your car is powered by a compressor, which, when switched on, places extra load on a car’s engine. This ultimately has a negative affect on the overall performance and efficiency. You can expect a 5-10% increase in fuel consumption by switching the air conditioning system on. Not dramatic enough to install a portable air conditioning device, such as a fan, pointing at your face but enough to make a difference.

But there are ways to limit its inefficiency; climate control systems in cars also include an air conditioner which automatically varies the amount of air conditioning depending on specific temperature set by the driver. Should you have a car with climate control, pressing ‘econ’ should switch off the air conditioning compressor, allowing you to drive more economically.

Many car manufacturers recommend that you keep the air-conditioning system on constantly, even if you are not using it to produce cold air. By continually circulating the coolant within the system all the parts are kept lubricated and in working order.

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.”

Toronto Residents Angered by Lack of Air Conditioning

Friday, June 4th, 2010, by Richard Salmon

Residents of WoodGreen community apartments – a housing project for people with HIV/AIDS in Toronto – are up in arms about the lack of sufficient air conditioning. The building, designed as a supportive housing area, lacks air conditioning in many rooms, areas that are home to hundreds of sick and unwell residents.

Temperatures in the housing units have exceeded 30ºC, leaving many residents unable to focus on tasks or live comfortably. Building staff have provided two cooled rooms in the lower floors, but many people are unable to access the shared cool areas due to disabilities or discomfort.

It’s certainly not the first public area in Toronto to lack adequate air conditioning. Many of the city’s high schools are left without air conditioning, deemed an unnecessary expense in Toronto’s harsh winter and a needless addition for the summer. With sweltering daytime temperatures, parents of students have expressed disbelief at the city’s refusal to install air conditioning systems.

For residents, portable air conditioning systems are a potential option. However, with many of WoodGreen’s residents lacking a source of income and reliant on building management, it remains unknown whether full access to cooled air will ever be available.

Indian Heat Wave: Temperatures Crack 50ºC in Northern Cities

Wednesday, May 26th, 2010, by Richard Salmon

India is known for its geographical diversity and unique culture, but it’s another subcontinental characteristic that’s gaining attention this month: the country’s truly staggering heat. A heat wave has rocked parts of India for the last month, causing over one hundred deaths and a lengthy list of infrastructure issues. Baha'i House of Worship - New Delhi, India by Adib Roy.

News stations have released various different heat-related death counts, putting the current figure between 120 and 140 people. Many north Indian homes lack air conditioning, leaving residents with few methods of completely sheltering themselves from the immense heat and seasonal humidity.

Temperatures have risen in the region for two years now, with 2009’s summer yielding some of the hottest temperatures on record. With recorded temperatures of over 49ºC, the current heat wave could go down in history as India’s warmest and most economically devastating, affecting thousands of farmers and potentially costing the warmest regions millions of dollars in lost agricultural income.

Residents of New Delhi, the country’s capital and India’s largest northern city have taken a unique approach to fighting the heat. Instead of relying on poor home cooling systems, locals have taken ‘long-distance’ continual rides on the city’s air conditioned subway system or invested in hand-fans and other portable air conditioning solutions.

New Delhi Robbers Use Air Conditioning ‘Gas’ Units

Monday, May 24th, 2010, by Richard Salmon

A gang of robbers in New Delhi have used air conditioners to aid their crimes, police claim. The thieves have stolen over £20,000 worth of jewellery and other luxury items from homes, each one rigged to ‘gas’ the residents into a sleep before robbers entered.

Most Indian air conditioners operate differently to their Western-style counterparts. In order to cool air more efficiently, the units funnel outside air through wet grass and ground and then into buildings. The alternative air conditioning systems are popular in South Asia, as they can cool the hot air more efficiently than standard units. out my apartment in bombay by Premshree Pillai.

They’re also significantly more at-risk of being tampered with, owing to their simplistic construction and outdoor installation. The gang of robbers had taken to modifying the portable air conditioning units to pump sleeping gas into homes, rendering residents unable to alert police to ongoing crimes.

Those affected by the crimes report smelling a “revolting odour” and feeling ill and uncomfortable before falling asleep. The substances used to rig air conditioners are currently unknown, although Indian police are involved in investigations to determine the ’sleeping gases’ and find the gang of robbers responsible for the crimes.
