Air Conditioning in Industry

Abstract

AIR conditioning, as the term implies, is the A treatment of air necessary to give certain conditions of heating, cooling, moistening, or drying of air contained in a given space. It may be more exactly defined as the application of scientific principles and engineering practice for the obtaining of specified and predetermined physical effects upon materials, human beings, or the atmospheric conditions in buildings, by treatment with air the temperature, humidity, and purity of which is definitely controlled. This treatment must, however, only be regarded as a means of securing a certain objective, either physiological effects on human beings, or physical effects on materials.
