Air humidification system for large enclosed spaces and humidification module usable in such system

Abstract

An air humidification system for large enclosed spaces, comprising at least one humidification line constituted by at least one humidification module comprising a box-like container with a water flow pipe inside which is functionally connected at its inlet to a water pump and at its outlet to a water discharge space. The pipe has, along its extension, a plurality of nozzles adapted to provide a water aerosol. The nozzles are open onto a first opening provided in the box-like container and are oriented toward the outside of the first opening. A cross-flow impeller is provided within the box-like container along a rotation axis which is parallel to the pipe and is suitable to aspirate air from a second opening of the box-like container and direct it toward the first opening.
