Abstract

Dans la présente invention, une unité de production d'eau d'acide hypochloreux (19) produit de l'eau d'acide hypochloreux. Une unité d'alimentation en eau d'acide hypochloreux (28) fournit l'eau d'acide hypochloreux de l'unité de production d'eau d'acide hypochloreux (19) à un réservoir de mélange (16). Une unité d'alimentation en eau (32) fournit de l'eau au réservoir de mélange (16). Une unité de détection de quantité d'eau (17) détecte la quantité d'eau dans le réservoir de mélange (16). Une unité de purification d'humidification (14) améliore un mélange d'eau de l'eau d'acide hypochloreux et de l'eau contenue dans la cuve de mélange (16) et le libère dans l'air. Une unité de commande (42) commande l'unité d'alimentation en eau d'acide hypochloreux (28), l'unité d'alimentation en eau (32) et l'unité de purification d'humidification (14). L'unité de commande (42) commande de manière dynamique le moment d'alimentation en eau d'acide hypochloreux par l'unité d'alimentation en eau d'acide hypochloreux (28) en fonction de la quantité d'humidification par l'unité de purification d'humidification (14) de sorte que la quantité d'acide hypochloreux contenue dans la quantité d'eau d'humidification par unité de temps est presque constante.
