Air Conditioning - Would it be Environmentally Friendly?


Air conditioning means the cooling of indoor air for thermal comfort. It refers in the broader sense; any kind of cooling, heating, ventilation, or disinfection that modifies the healthiness of air. Any appliance, system, or machine which is designed to stabilize the environment temperature and humidity within an area (useful for cooling as well as heating with respect to the air properties in a given time), is referred to as an aura conditioner. Typically this uses a refrigeration cycle but sometimes evaporation, which is commonly for comfort cooling in buildings and automobiles.

Modern air conditioning emerged from advances in chemistry in the 19th century, and it was recorded the first large-scale electrical air-con was invented and utilized in 1902 by Willis Haviland Carrier in Buffalo, New York. The first air conditioners and refrigerators employed toxic or flammable gases like ammonia, methyl chloride, and propane which could result in fatal accidents after they leaked.

Air conditioning is broadly divides to comfort and process applications. In Comfort Applications it aims use a building indoor environment that remains relatively constant in the range preferred by humans despite alterations in external weather conditions or perhaps in internal heat loads, whereas in Process Applications it aims at providing a suitable environment for any process being performed, regardless of internal heat and humidity loads and external weather conditions. In addition to buildings, air conditioning can be used for many types of transportation - motor-cars and other land vehicles, trains, ships, aircraft, and spacecraft. Although often in the comfort range, it is the needs of the process that determine conditions, not human preference. In both comfort and process applications, the objective may be to not only control temperature, but additionally humidity, air quality and air movement from space to space.


Though built for man's comfort, air-con can constitute smog. Air pollution is the introduction of chemicals, particulate matter, or biological materials that induce harm or discomfort to humans and other living organisms, or damages all-natural environment into the atmosphere. Considering that the atmosphere is a complex dynamic natural gaseous system that is essential to support life in the world, its pollution will drastically affect human health and also the Earth's ecosystems.

Since chronic, low-level experience various chemicals, e.g., lead exposure - even at relatively 'abnormal' amounts - may result in numerous adverse outcomes, continuous contact with air conditioning appliances can have severe effects, like anaemia, malaise, and damage to the nerves. Children are particularly at risk of the neurotoxic effects of lead. Relatively low levels of exposure can reduce their IQ scores, cause learning disabilities, poor school performance, and violent behaviour, all of which may contribute to reduced lifetime earnings.

Aside from the problem of stratospheric ozone depletion, indoor pollution and urban air quality are listed because world's worst pollution problems within the 2008 Blacksmith Institute World's Worst Polluted Places report. Though atmospheric pollution could be caused by other combustible materials for example open burning of refuse, old tyres, old vehicles, exhaust pipes of engines and other locomotives which pollute the surroundings, yet pollution from air conditioning units are very dangerous. Protection against atmospheric pollution is very important because a lot of diseases like respiratory system infections can occur at their store and the major constituent of the gases which is carbon-monoxide can avoid the free flow of blood in the body by impairing the oxygen carrying capacity in the hemoglobin. A poorly maintained air-conditioning system will often promote the growth and spread of microorganisms, the infectious agent in charge of Legionnaires' disease, but as long because air conditioner is kept clean these health hazards can be avoided.

Conversely, air cooling, including filtration, humidification, cooling, disinfection, etc., enables you to provide a clean, safe, hypoallergenic atmosphere in hospital operating rooms and other environments where a proper atmosphere is critical to patient safety and well-being. Air cooling can have a positive effect on sufferers of allergies and asthma. In serious heat waves, air conditioning can save the lives from the elderly. Some local authorities have set up public cooling centers for people without home air conditioning.
