A ducted air humidifier includes a housing containing a water tray, a valve for supplying water to the tray, a float for controlling the water level in the tray, and an evaporator, the housing of which contains a water-absorbing and air-permeable honeycomb material, is provided with an electric drive for controllable rotation of the evaporator about the axis thereof. Furthermore, the evaporator is mounted so as to be partially and adjustably submerged in the water tray. If the honeycomb material of the humidifier is anisotropic, then in order to increase the uniformity of air humidification, several layers of honeycomb material are arranged in the housing of the evaporator, the layers of honeycomb material being offset from one another about the axis of the evaporator to increase the effectiveness of air humidification in ducted air humidifiers.

A humidifier includes a shell, a fixing bracket, an atomizer, and a control circuit assembly, and the fixing bracket is disposed in a containing cavity of the shell and divides the containing cavity into a first isolating cavity and a second isolating cavity opposite to each other; the control circuit assembly is disposed in the first isolating cavity, and a solution is contained in the second isolating cavity; the atomizer is positioned in the solution of the second isolating cavity and electrically connected to the control circuit assembly. The control circuit assembly controls the atomizer to atomize the solution.

An evaporative cooling device may be provided. The device may comprise a plurality of rollers, a screen looped around the plurality of rollers, a motor coupled to at least one roller and configured to drive the at least one roller, a basin configured to hold a liquid within an interior of the basin, and wherein at least one roller is at least partially within the interior of the basin. The screen may travel into the basin and capture an amount of the liquid. As the liquid is drawn into an airstream feeding a heat rejection device, the liquid may evaporate, cooling the air. The cooled air may provide a more efficient heat rejection device.

An air scrubber has an electrically driven fan and a drum having a mat forming a closed circulating band spanning a support of the drum. The mat is electrically rotatably driven about a rotation axis, wherein a lower part of the drum is immersed in a water basin. The mat can be removed from the drum by a movement in the axial direction and pushed back on again by a movement in the axial direction.

Presented is a humidifier, comprising: a rotatable wick (101); a means for rotating the wick (102); characterized in that: the humidifier further comprises a disinfection unit (103a, 103b) adapted such that different parts of the wick are disinfected when the wick rotates.

A humidifier includes a main housing, a fan unit and an air guiding arrangement, which includes a guiding roller and a partitioning assembly. The partitioning assembly is supported in the main housing at a position adjacent to the guiding roller to substantially enclose the water storage compartment. The partitioning assembly defines at least one air slot and an air passage channel, wherein when the fan unit and the guiding roller are driven to rotate, air is drawn from the air inlet and guided to pass through the air slot to reach the water storage compartment for effectively mixing with the water in the water storage compartment to form a predetermined amount of mist. The mist is arranged to pass through the partitioning assembly through the air passage channel and the fan unit, and eventually discharged out of the main housing.
