Air conditioning WikipediaAC redirects here. For other uses, see AC. Air conditioning units outside a building. Air conditioning often referred to as AC, A. C., or AC is the process of removing heat from the interior of an occupied space, to improve the comfort of occupants. Air conditioning can be used in both domestic and commercial environments. This process is most commonly used to achieve a more comfortable interior environment, typically for humans or animals however, air conditioning is also used to cooldehumidify rooms filled with heat producing electronic devices, such as computer servers, power amplifiers, and even to display and store artwork. Air conditioners often use a fan to distribute the conditioned air to an occupied space such as a building or a car to improve thermal comfort and indoor air quality. Electric refrigerant based AC units range from small units that can cool a small bedroom, which can be carried by a single adult, to massive units installed on the roof of office towers that can cool an entire building. The cooling is typically achieved through a refrigeration cycle, but sometimes evaporation or free cooling is used. Air conditioning systems can also be made based on desiccants chemicals which remove moisture from the air and subterraneous pipes that can distribute the heated refrigerant to the ground for cooling. 1In the most general sense, air conditioning can refer to any form of technology that modifies the condition of air heating, cooling, de humidification, cleaning, ventilation, or air movement. In common usage, though, air conditioning refers to systems which cool air. In construction, a complete system of heating, ventilation, and air conditioning is referred to as heating, ventilation, and air conditioning HVAC as opposed to AC. 2HistoryeditEvaporative coolingeditSince prehistoric times, snow and ice were used for cooling. The business of harvesting ice during winter and storing for use in summer became popular towards the late 1. This practice was replaced by mechanical ice making machines. The basic concept behind air conditioning is said to have been applied in ancient Egypt, where reeds were hung in windows and were moistened with trickling water. The evaporation of water cooled the air blowing through the window. This process also made the air more humid, which can be beneficial in a dry desert climate. In Ancient Rome, water from aqueducts was circulated through the walls of certain houses to cool them. Other techniques in medieval Persia involved the use of cisterns and wind towers to cool buildings during the hot season. 4The 2nd century Chinese mechanical engineer and inventor Ding Huan of the Han Dynasty invented a rotary fan for air conditioning, with seven wheels 3 m 1. In 7. 47, Emperor Xuanzong r. Tang Dynasty 6. 189. Cool Hall Liang Tian built in the imperial palace, which the Tang Yulin describes as having water powered fan wheels for air conditioning as well as rising jet streams of water from fountains. During the subsequent Song Dynasty 9. In the 1. 7th century, the Dutch inventor Cornelis Drebbel demonstrated Turning Summer into Winter as an early form of modern air conditioning for James I of England by adding salt to water. 7Development of mechanical coolingeditModern air conditioning emerged from advances in chemistry during the 1. American inventor Willis Carrier. The introduction of residential air conditioning in the 1. Sun Belt in the United States. citation neededIn 1. Benjamin Franklin and John Hadley, a chemistry professor at Cambridge University, conducted an experiment to explore the principle of evaporation as a means to rapidly cool an object. Franklin and Hadley confirmed that evaporation of highly volatile liquids such as alcohol and ether could be used to drive down the temperature of an object past the freezing point of water. They conducted their experiment with the bulb of a mercury thermometer as their object and with a bellows used to speed up the evaporation. They lowered the temperature of the thermometer bulb down to 1. C 7 F while the ambient temperature was 1. C 6. 4 F. Franklin noted that, soon after they passed the freezing point of water 0 C 3. F, a thin film of ice formed on the surface of the thermometers bulb and that the ice mass was about 6 mm 14 in thick when they stopped the experiment upon reaching 1. C 7 F. Franklin concluded From this experiment one may see the possibility of freezing a man to death on a warm summers day8In 1. English scientist and inventor Michael Faraday discovered that compressing and liquefying ammonia could chill air when the liquefied ammonia was allowed to evaporate. In 1. 84. 2, Florida physician John Gorrie used compressor technology to create ice, which he used to cool air for his patients in his hospital in Apalachicola, Florida. He hoped to eventually use his ice making machine to regulate the temperature of buildings. He even envisioned centralized air conditioning that could cool entire cities. Though his prototype leaked and performed irregularly, Gorrie was granted a patent in 1. Though his process improved the artificial production of ice, his hopes for its success vanished soon afterwards when his chief financial backer died and Gorrie did not get the money he needed to develop the machine. Welcome to the VA Office of Small And Disadvantaged Business Utilization OSDBU. In 1902, the first modern electrical air conditioning unit was invented by Willis Carrier in Buffalo, New York. After graduating from Cornell University, Carrier.

OIL BURNER WONT RUN CONTENTS Diagnostic steps for an oil burner that wont start. According to his biographer, Vivian M. Sherlock, he blamed the Ice King, Frederic Tudor, for his failure, suspecting that Tudor had launched a smear campaign against his invention. Dr. Gorrie died impoverished in 1. James Harrisons first mechanical ice making machine began operation in 1. Barwon River at Rocky Point in Geelong Australia. His first commercial ice making machine followed in 1. This novel system used a compressor to force the refrigeration gas to pass through a condenser, where it cooled down and liquefied. The liquefied gas then circulated through the refrigeration coils and vaporized again, cooling down the surrounding system. The machine produced 3,0. Though Harrison had commercial success establishing a second ice company back in Sydney in 1. American advantage of ice refrigerated beef sales to the United Kingdom. He wrote Fresh meat frozen and packed as if for a voyage, so that the refrigerating process may be continued for any required period, and in 1.

Norfolk for an experimental beef shipment to the United Kingdom. His choice of a cold room system instead of installing a refrigeration system upon the ship itself proved disastrous when the ice was consumed faster than expected. citation neededElectrical air conditioningeditIn 1. Willis Carrier in Buffalo, New York. After graduating from Cornell University, Carrier found a job at the Buffalo Forge Company. While there, he began experimenting with air conditioning as a way to solve an application problem for the Sackett Wilhelms Lithographing and Publishing Company in Brooklyn, New York. The first air conditioner, designed and built in Buffalo by Carrier, began working on 1. July 1. 90. 2. citation neededDesigned to improve manufacturing process control in a printing plant, Carriers invention controlled not only temperature but also humidity. Carrier used his knowledge of the heating of objects with steam and reversed the process. Instead of sending air through hot coils, he sent it through cold coils filled with cold water.
