Abstract

L'invention concerne une technique de nettoyage et de stérilisation qui, dans un environnement comportant de multiples zones présentant des niveaux différents de prise en charge de l'hygiène dans un espace unique, peut assurer le nettoyage et la stérilisation conformément aux divers niveaux de prise en charge de l'hygiène. Ce procédé de stérilisation implique une stérilisation conforme à chaque niveau de prise en charge de l'hygiène dans un environnement dans lequel existent de multiples zones 2 à 8 présentant différents niveaux de prise en charge de l'hygiène. Dans ce procédé, de l'eau électrolysée, générée par l'électrolyse de l'eau à électrolyser, est vaporisée, et la matière gazeuse formée de l'eau électrolysée vaporisée est mise en circulation dans une zone (la sixième zone 8) des multiples zones, et stérilise ladite zone.
