Full Description

Air conditioning of industrial plants is often dismissed as being too costly both in first cost and operating cost. In the period from 1960 to 1970, one of the investigators was retained by a major industrial corporation to study the environment of its automotive assembly plants. At that time this corporation used exhaust ventilation and velocity cooling in most of the plants. It was felt that air conditioning might be a better alternative when one considered the large amount of duct work and related equipment needed to supply the air necessary to maintain thermal conditions at all close to the comfort zone of ASHRAE Standard 55-74. Studies by Olivieri indicated that air conditioning shoud have an installed cost equal to or less than ventilating systems with a lower energy usage.
