The invention relates to a method and apparatus for precise temperature and humidity control within a confined or determined chamber. Essentially, the method involves determining a desired condition in a controlled space. The essence of the concept is to provide humidity control by the addition of moisture at all operating conditions and, in effect, never having to control dehumidification. Hence, the system is much more controllable than previous approaches, which as a result achieves energy conservation. In addition, the method for heating or cooling is to insure that the heating or cooling does not affect the humidity, but that humidity is added after all the desired temperature relationships are achieved, which enables the system to eliminate control into the dehumidification mode. Further, the process includes a higher air flow rate than normally utilized, all of which improves the precision of the humidification and temperature control process. The apparatus to achieve the invention is arranged in a neat configuration to achieve better mixing of steam humidification with dry heated air, the positioning of the apparatus to achieve the desired air flow characteristics through the room, and more uniformity with substantial elimination of temperature variations by lights, or people entering or leaving. Further, the apparatus includes structure to cool the conditioned air without stripping moisture. The system is overall more energy conservative when contrasted to previous systems because only a small percentage of makeup air is added to a large quantity of circulated air with the makeup in effect controlling the temperature and humidity of the circulated air.

A method to achieve precise controlled humidity and temperature within a confined space wherein the process operates to the right of a line of a physchrometric chart between the point of desired temperature and humidity entering the confined space and the temperature and humidity in the air leaving

A method to achieve precise controlled humidity and temperature within a confined space wherein the process operates to the right of a line of a physchrometric chart between the point of desired temperature and humidity entering the confined space and the temperature and humidity in the air leaving the space, comprises the steps of: (a) effecting circulation of a predetermined volume of air through the control space to achieve a substantially uniformed distribution of the air throughout the space; (b) thoroughly mixing into the main stream a small portion of makeup air at a controlled humidity and temperature level to return the main stream to about the desired temperature and humidification levels; (c) additionally selectively cooling the main stream of air with makeup air mixed without stripping any moisture therefrom; (d) selectively adding moisture to the mixed air flow stream to bring the humidification level up; (e) providing moving force to the air stream immediately subsequent to moisture addition to uniformly distribute the moisture throughout the air stream; and (f) effecting control of the makeup air input, the selective cooling and selective moisture addition by control means within the confined space.
