Air conditioning means the cooling of indoor air for thermal comfort. It refers in a broader sense; any form of cooling, heating, ventilation, or disinfection that modifies the condition of air. Any appliance, system, or machine naturally designed to stabilize atmosphere temperature and humidity in an area (used for cooling as well as heating depending on the air properties at a given time), is referred to as an air refresher. Typically this uses a refrigeration cycle but sometimes evaporation, which is commonly for comfort cooling in buildings and motor one of the biggest.
Modern air conditioning emerged from advances in chemistry during the 19th century, and it was recorded that the first large-scale electrical air conditioning was invented and used in 1902 by Willis Haviland Carrier in Buffalo, The big apple. The first air conditioners and refrigerators employed toxic or flammable gases like ammonia, methyl chloride, and propane which you could end up fatal accidents when they leaked.
Air conditioning is broadly divides to comfort and process applications. In Comfort Applications it aims to provide a building indoor environment that remains relatively constant in a range preferred by humans despite changes in external weather conditions or in internal heat loads, whereas in Process Applications it aims at providing a suitable environment for a process being carried out, 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 as comfort range, it’s the needs of the task that determine conditions, not human desire. In both comfort and process applications, the aim may be to not only control temperature, likewise humidity, air quality and air movement from space to space.
Though built for man’s comfort, air cooling can constitute air pollution. Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural world into the environs. Since the atmosphere is a complex dynamic natural gaseous system that is important to support life on planet Earth, its pollution will drastically affect human health as well as you move the Earth’s ecosystems.
Since chronic, low-level exposure to various chemicals, e.g., lead exposure – even at relatively ‘abnormal’ amounts – may lead to a number of adverse outcomes, continuous contact with air conditioning appliances can have severe effects, such as anaemia, malaise, and damage to the nervous system. Babies are particularly vulnerable into the neurotoxic effects of lead. Relatively low levels of exposure to decrease their IQ scores, cause learning disabilities, poor school performance, and violent behaviour, all of which may contribute to reduced lifetime earnings.
Apart from issue of stratospheric ozone depletion, indoor smog and urban air quality are listed because world’s worst pollution problems in the 2008 Blacksmith Institute World’s Worst Polluted Places report. Though atmospheric pollution can be caused by other combustible materials such as open burning of refuse, old tyres, old vehicles, exhaust pipes of engines and other locomotives which pollute the environment, yet pollution from air conditioners are very unfavorable. Prevention of atmospheric pollution is very important because a involving diseases like respiratory system infections can occur from them and the major constituent of all of these gases which is carbon-monoxide can steer clear of the free flow of blood in cups of water by impairing the oxygen carrying capacity of the hemoglobin. A poorly maintained air-conditioning system can on occasion promote the growth and spread of microorganisms, the infectious agent responsible for Legionnaires’ disease, but as long as the air conditioner is kept clean these health hazards can be avoided.
Conversely, air conditioning, including filtration, humidification, cooling, disinfection, in addition to., can be used to provide a clean, safe, hypoallergenic atmosphere in hospital operating rooms and other environments where an appropriate atmosphere is vital to patient safety and well-being. Air conditioning can have a positive effect on sufferers of allergies and all about asthma. In serious heat waves, air conditioning helps save the lives for the elderly. Some local authorities have even set up public cooling centers with regard to without home air conditioner.
