GM will use "greenhouse gas-friendly" A/C refrigerant in U.S. vehicles

There are some people who cool their cars down with ice, but General Motors thinks drivers like standard air conditioning. Since the refrigerant used in most automotive air conditioning systems is not good for the environment, GM is proud to announce it will use a better type of refrigerant (called HFO-1234yf) in its vehicles that it s

California leaves "cool cars" regulation out in the, ahem, cold

The California Air Resources Board (CARB) has announced that the "cool cars" regulation has been canceled. "Cool cars" tried to reduce the need for air conditioning in new vehicles by mandating that their windows reflect or absorb a portion of the heat-producing rays from the sun.

Nissan Forest air-con utilizes aromatherapy, 'natural' breezes to reduce fatigue

Rolling down your vehicle window to get a breath of fresh air may be unnecessary in your next Nissan. The Japanese automaker just announced the development of its new "Forest AC" air conditioning system, an automotive climate control setup designed to control humidity, aroma, and other ambient factors in addition to the temperature and air cleaning features found with current systems. According to Nissan, the Forest AC is the first automotive system in the world created to make driving more comf

Efficient air conditioning could potentially save billions of gallons of gas

The U.S. Department of Transportation and National Renewable Energy Lab (NREL) are hard at work developing new ways to make the air conditioners more efficient and reduce the interior tempteratures in our cars and trucks. What's the big deal? Apparently, a whopping seven billion gallons of gasoline are used each and every year in the United States alone to run automotive AC units, which repr

EU calls for new eco-friendly air conditioners by 2011

Following a directive first created back in 2006, the European Union has passed down a ruling that would force European automakers to find a new refrigerant to use in their vehicle's air conditioners. There's some debate as to the timing of this mandate, as it's no secret that most automakers are in a fight to just remain in business.

Automakers work on sustainable air conditioning

It wasn't all that long ago that the auto industry was under fire for its use of ozone-depleting chemicals in its air conditioning systems. To curb those fears, the older R-12 refrigerant was replaced with R-134a refrigerant. Interestingly enough, CO2, long associated with harmful automobile emissions, is being touted as a desirable natural replacement for the chemical s

Are high gas prices making your car sick?

While "sick car syndrome" has been known about for quite some time now, the recent rise in gas prices may be causing a resurgence of sorts to the odd but mostly preventable issue. The cause of the problem is the air conditioning of your automobile, which features an evaporator which can be a haven for fungi, mold and mildew. If the AC unit is not switched on regularly, a buildup of the unwanted guests can be bl

Mobile Air Conditioning Society Worldwide: recycle your refrigerant

Even though the older types of refrigerant like Dichlorodifluoromethane (R-12) have been replaced with newer types like Tetrafluoroethane (R-134a), your car's air conditioning system could still be damaging to the environment. While not as harmful as the older refrigerants, recent research suggests that R-134a refrigerant is collecting in

How far would you go for A/C?

Scott Dawson finally had enough. After three years of motoring around town with no A/C in his car, this civil engineering grad from the University of Houston decided to do something about it. Rather than coughing up the $1,200 in cash to fix the A/C inside his car, he just bolted an aftermarket unit to the outside of his car. The cooler of choice for Dawson was a home-intended window A/C unit from Samsung. He just cut a whole in his roof and strapped it down and ran some duct work to blow air ri

Air conditioning could soon cost a lot more for Euro drivers

Air conditioning was once considered a luxury option but in the past decade it has become almost universally standard equipment. New European Union rules could put a stop to that for drivers over there. In an attempt to reduce atmospheric emissions of hydrofluorocarbons, the rules would require a standard of qualifications for engineers working on air conditioning systems which may raise the cost of developing systems.

Windshield reflects sun -> cools car -> reduces aircon -> improves mpg!

Picture the scene - its a stinking hot day and you're glad the windows are up and the air conditioner is on. But what setting do you have the chill on? You know in the long run that it all adds up to more fuel burnt and money spent if that bad boy's set to deep freeze.
