About air conditioning Bashny.Net

Air conditioning everywhere today. They help to put up with the heat, but also pose a threat. Interestingly, although the word has become customary for us not so long ago, the first air conditioners were invented thousands of years ago yet.





Perpetuum Mobile



The word "conditioner" was included & quot; in our active vocabulary is not so long ago. First sitsemy conditioning were produced in the Soviet Union only in the 70 years of the twentieth century. In the 90s it became fashionable to have a car with a "kondishn».
However, the problem itself conditioning, that is, if translated literally, improve air was always true. Great strides in overcoming it made the ancient Hindus. There is still cultivated vetiver grass, which is a natural air conditioner - cleans the air, provides a powerful cooling effect, treats malaria, fever and arthritis, reduces inflammation, fever and burning.
In addition, it is in India thousands of years ago still was invented a kind of "perpetual motion" with the effect of conditioning the room. He worked as simple and ingenious: on-site front door frame was placed upholstered Tatti (coconut), placed over it capacity, which was filled with moisture by capillary action. When the moisture reaches a certain level, the capacity of tipping and again poured over the frame.

Live conditioner



Camel - a unique animal, he is able to survive in such conditions where other fauna long would "lay down their legs." This is partly explained by the fact that camels are real live air conditioning. Dry air in the nose of a "ship of the desert" is saturated with moisture, and only then to the lungs. Amazingly, when you exhale camel does not give this moisture and filters it again, breathing in the cool air of the environment. This temperature difference can be up to 9 ° C. The man is, for example, the temperature of the exhaled air is temperature of his body (which is why, if breathe on a mirror, it will condensate, a camel this effect will not be).

Half the price of the machine



Nowadays the car without air conditioning is difficult to imagine, but the history of automobile air conditioners began only in 1939. The first car equipped with air-conditioning system, was "Packard". It was not yet mass production. While the "Ford" cost an average of 742 dollars, the cost of the air conditioner could be up to 250. In addition, consumer prices also confused many dimensions and weight of the installation - it took almost the entire trunk, did not have a thermostat and are not included. Cumbersome and expensive "improvers" automotive air market lasted only two years.
More acceptable and the price and quality of automobile air conditioners appeared later - in the 50s. They were installed in the cars' Nash Ambassador ". The first adjustable climate control was set to "Cadillac" only in 1968.

Danger



That the use of air conditioners poses a potential threat to health, say and write a lot. The first danger - directed cold air conditioners can cause myositis and cause colds. Also affect the health of the temperature difference, it could trigger a heat stroke and weakened immunity.

Conditioners and dangerous for people with allergies - on filters dusty plants, fungi, streptococci, staphylococci. In buildings where still used central air conditioning, there is a possibility of infection "Legionnaires' disease" - a rare form of pneumonia.
Another danger posed by air conditioners is that they dry air. From this can dry out the nasal mucosa and a person's chances of catching an infection increases significantly. Air conditioners do not clean the air and recycle carbon dioxide into oxygen and chase the air in the room. From this office imbalance may occur between the positively and negatively charged air ions. Number of positive ions increases, so air can not be considered useful to humans. Plus, the lack of light ions, some of which remain in the air conditioner makes the air "dead».

Precautions



What you need to do to avoid the problems that can bring into our lives conditioners? Firstly, they need to be cleaned regularly. Filters can wash themselves and change their own, but at least once a year, it is necessary to perform a complete cleaning of air conditioning systems. Secondly, you need to ensure that the temperature difference outside and inside the building did not exceed 9 ° C. Third, even with the use of split systems, it is necessary at least once a day to make room ventilation when the air conditioner is turned off. Air Conditioning - the same refrigerator, surpassing the same air (not always clean) indoors, it impoverishes him and only pollutes. Finally, we must ensure that the jet of air from the air conditioner was not aimed directly at the person. The best option - up. And do not forget from time to time just to turn off air conditioning, if available. This is especially important for motorists. From always-on conditioner driver, who has long breathes depleted air can worsen the reaction rate and even dizzy, which is fraught with trouble on the road.
