The design of saturated steam dispersion apparatus installed either in ducts or in air handling units (AHU) is studied in order to avoid wetting any HVAC components during humidification process. The non-wetting distance (NWD) correspond to the distance, downstream the steam dispersion apparatus, at which any obstacle to the humid airstream can’t get wet. An experimental method to measure such distance has been proposed. Experimental data, consisting of non-wetting distance, humidity ratios upstream and downstream humidification as well as steam dispersion apparatus configuration have been collected. Steam dispersion apparatus consist of vertical steam dispersion distributor (VSDD) where their configuration refers to the equal distance between each of them. Results show that the distance between de VSDD increases NWD. For any fixed air humidity increasement, the upstream humidity ratio also varies the NWD. Regressions are used to establish equations that would predict experimental data. From those equations, a steam dispersion apparatus design algorithm is then developed based on available upstream distance and humidification parameters. The effect of air humidity homogeneity on the results is discussed and further experimental measurement improvements are formulated.
