Project Report on Assembly Of Air-Conditioner

The early attempts at air conditioning were aimed solely at providing human comfort. Coider fields were sought to be covered in the nineteenth century, and it was during this period that the foundation of modern air conditioning was laid with the controlling of humidity conditions in cotton textiles mills. In the initial stages, the air in the textile mills was humidified by evaporating water from steam ports in order to reduce breakages and static electricity of cotton yarns. The principles of air conditioning were then gradually extended to industries like printing. Candy making, wood production, tobacco manufacturing and to the storage of food and other perishable products. By 1897, the first form of humidification, namely an air washer, was patented and used on a wider scale. It cooled and humidified  in addition to its primary function of  cleaning the air. The term air-conditioning was first suggested and used in 1906 by an American Stuart W.Cramer, who developed an air conditioning system which could control both humidity and temperature. At about the same time, another American, Willis H.Carrier, devised a control air conditioner unit of  the air washer type which automatically controlled  the humidity and saturation temperature of the air. With the development of  new machines the applications of air conditioning were extended to the fields of commerce and transport. Commercial air-conditioning was started with the more heartness. In 1930, a small unitary air-conditioner was first installed in a railway coach operating in the Baltimore and Ohio railroad of the USA. In 1931 entire train running between New York and Washington was air-conditioned.
