A General Approach to the Air-Conditioning System essays Human beings are born into a hostile environment, but the degree of hostility varies with the season of the year and with the geographical locality. For removing these effects of environment and changing outdoor conditions to the conditions we feel comfortable we use mechanical systems. Air conditioning system is the most developed system using for this purpose. Automotive air conditioning systems are used for controlling the conditions of air using in automotive. After investigations, negative effects of this system on the automotive are minimized and with using safety devices the usage area of the system are broaden. Now automotive air conditioning system are one of the most needed systems in automotive. Full air conditioning implies the automatic control of an atmospheric environment either for the comfort of human beings or animal or for the proper performance of some industrial or scientific process. The adjective full demands that the purity, movement, temperature and relative humidity of the air be controlled, within the limits imposed by the design specification. Air conditioning is always associated with refrigeration and it accounts for the high cost of air conditioning. The ability to counter sensible and latent heat gains is, then, the essential feature of an air conditioning system and, by common usage, the term air conditioning means that refrigeration is involved. Human beings are born into a hostile environment, but the degree of hostility varies with the season of the year and with the geographical locality. This suggests that the arguments for air conditioning might be based solely on climatic considerations, but although these may be valid in tropical and subtropical areas, they are not for temperate climates with industrialized social structures and rising standards of living. Air conditioning is necessary for the following reasons. Heat gains from human bodies, sunlight and el...
