Air conditioning of air supply for emulsion paint spray cabin - controlling humidity matched to each exterior air temp. and fixing of constant psychrometric temp. difference measured by known psychrometer

摘要

The psychrometer (Ps) is acted upon with the same water soln. mixture (WL) as the mixture applied in the paint. The temp./humidity regulation is necessary to produce the required finishing result when using automatic spraying or robots. When spraying by hand, the experienced sprayer can balance different parameters. With measurement values above the line of constant psychrometric difference, moisture (6, 6a) is applied, with measurement values under this line, the heating elements (5, 5a) are connected into the circuit. ADVANTAGE - Regulation is carried out without expensive auxiliary units, and has stable operation at any time of year and under all external weather conditions.
