Air conditioning of industrial plants is not a luxury; it is essential. Man is entitled to an environment reasonably close to that of his home: this requires air conditioning. Air conditioning also reduces energy consumption.

Therefore it was felt that (a) a study of the effects that supply outlets and return openings have on temperature stratification, (b) a study of the effects of using radiant cooling panels on the temperature stratification was necessary.
