HVAC application areas
Too low room humidity can lead to health problems through drying out of the mucous membranes. Dryness affects the functioning of the cilia in the air passages. Consequently the self-cleaning of the air passages is impaired and the susceptibility to colds increased.
Plastic parts become electrically charged in low air humidity and attract dust particles. Additionally unpleasant discharge effects can occur when touching charged surfaces.
The air in heated rooms becomes especially dry in winter. Air conditioned systems that only circulate the air by mixing it proportionally with fresh air will not humidify the room. Whereas room air humidifiers will contribute to the well-being and health for people who remain in rooms for longer periods of time.
Room air humidifiers are used in office spaces just as in schools, nurseries, hospitals and operating theatres. In such areas air humidities of 30-65% r.h. (for operating theatres in hospitals as high even as 50-70%) are recommended.
Electrostatic charging will be reduced above 40% r.H. and can even be prevented if air humidification is increased. This is essential, especially in computer rooms, IT centres and telephone exchanges.
