Automobile Air Conditioning Info: Automatic Temperature Control, Freon And The Environment

Published: August 15, 2007
The summers of the 21st century have overwhelmed both American and global populations with their cloying, heavily-sticking heat. Air conditioners have become a must for households everywhere; except for that rare individual who is not made ill-at-ease during extremely hot and humid weather. Beyond homes, a car can be one of the worst places to be when the weather is scorching.
There is nothing more torturous than sitting in a sweltering car during rush hour, unable to get out.
Automobile air conditioning is just as necessary as air conditioning for the home. It can make that long rush hour in late July bearable, even comfortable. But automobile air conditioning, like most technologies, has had some adverse effects on the environment.
The environmental concerns over automobile air conditioning are centered on the refrigerant by which it is powered. A refrigerant is any one of several chemical cooling agents which work by absorbing heat when it vaporizes. The temperatures produced from such a reaction can be shockingly cold. Therefore, they are perfect for fueling automobile air conditioning.
However, the types of refrigerants used in automobile air conditioning have been proven to contribute to depletion of the ozone layer. This ironically worsens global warming when actually intended to make the air cooler. Freon is one of the cooling substances in automobile air conditioning coming under fire due to this unforeseen problem. It is also referred to as R12 and was originally developed by chemists at DuPont. As long ago as 1994, the Environmental Protection Agency (EPA) published a report which detailed the then-current concerns about Freon's dangerous qualities, which are still being validated today.
In stores which carry automobile air conditioning equipment, it was once possible for customers to buy their own cans of Freon and add it to their cars themselves. Now it is forbidden in the United States and in other nations as well. They made this decision in the Montreal Protocol during the 1980s, after the nations met to address ozone layer concerns. Freon has since been replaced by the R-134a refrigerant for automobile air conditioning. The EPA advises consumers to check the Federal Register's list of viable alternative coolants to Freon, and others like it.
Automatic temperature control systems as a means of automobile air conditioning offer some hope on the horizon. It is one of the many technological advances that have cropped up in the newer car models during the past several years. The effectiveness of automatic temperature control systems is based on the acutely perceptive sensor mechanisms which detect the current temperature and adjust it to human comfort levels within the vehicle. It is so far the best automobile air conditioning mechanism yet developed.
However, this convenient breakthrough is still not problem-free. As far as refrigerants are concerned, they are still needed in this newer form of automobile air conditioning. R-134a has been called much less dangerous than Freon, but it soon may be replaced by yet another cooling substance for automobile air conditioning. Because problems with the environment are becoming increasingly more threatening, scientists around the world are on the lookout for safer coolants for automobile air conditioning.
While automobile air conditioning continues to be a necessity in these torrid summers, there is no reason why the planet should suffer so human beings can be comfortable. It is perfectly feasible both can avoid overheating at the same time; this is the aim of the present advancements being made in air conditioning.
