RATIONAL PSYCHROMETRIC FORMULAE
THEIR RELATION TO THE PROBLEMS OF METEOROLOGY AND OF AIR CONDITIONING
By Willis H. Carrier
ABSTRACT OF PAPER
In many industries such as the manufacture of textiles, food products, high explosives, photographic films, tobacco, etc., regulation of the humidity of the atmosphere is of great importance. This paper deals with the subject of the artificial regulation of atmospheric moisture, technically known as air conditioning. It gives a theoretical discussion of the subject in which formulae are developed for the solution of problems. These formulae are based upon the most recently determined data and in order to establish a logical basis for the presentation of these data and the derivation of the formulae, the principles governing atmospheric moisture are reviewed and the present methods of determining atmospheric humidity are discussed.
