A humidifier/dehumidifier device is disclosed herein. The humidifier and dehumidifier both, respectively, evaporate water from and condense water into a shared (same) water storage container. The device is fitted with an air intake and at least one air outtake. In embodiments of the technology, one or more of the air intakes receives air from outdoors. One or both of an indoor and/or the outdoor intake is used to receive air based on a determination that an indoor and outdoor humidity and temperature is most efficient to achieve a desired indoor humidity or temperature.

A method for applying a chemical treatment to a cooling medium in an evaporative cooling system. The method includes applying the chemical treatment to the cooling medium, and the chemical treatment includes at least one of a phosphonate and a dispersant polymer.

An antibacterial device that includes a substrate, a first electrode on the substrate, a second electrode on the substrate, and a protective layer covering the first electrode and the second electrode and having a first surface opposing of the substrate and a second surface opposite the first surface. Further, the first electrode and the second electrode are arranged such that the protective layer has an electric field strength on the second surface thereof of 150 kV/m or more when a voltage is applied to the first electrode or the second electrode.

The invention provides a humidifier apparatus (100) comprising (i) a first chamber (110) for containing water (101), (ii) a humidifying element (120) configured to facilitate evaporation and/or nebulization of water (101) contained in the first chamber (110), wherein the humidifying element (120) comprises a wick element (130), (iii) a replaceable or refillable unit (230) for containing an immobilized phosphate removing material (150), wherein the phosphate removing material (150) is configured to reduce a concentration of phosphate in water (101) before evaporation and/or nebulization of the water (101), and wherein the wick element (130) comprises the phosphate removing material (150), wherein the phosphate removing material (150) is comprised by the wick element (130) as one or more of impregnated phosphate removing material (150) and coated phosphate removing material (150), and wherein the wick element (130) is configured as the replaceable unit (230). Further, a wick element (130) comprising a phosphate removing material (150) is presented.

A convertible humidifier that includes a base portion that produces mist, a control panel that controls the production of the mist by the base portion, a reservoir, detachably connectable to the base portion, which holds water to be used by the base portion to produce the mist, and a nozzle configured to direct the mist. The reservoir includes a pass-through connection that allows the mist produced by the base portion to be directed to an opening on a top surface of the reservoir. The nozzle is detachably connected to the opening on the top surface in a first operation mode, and the nozzle is detachably connected to an extending portion, which is detachably connected to the opening on the top surface, in a second operation mode.

A sterilization and humidification apparatus includes a heating chamber, a filter and a humidification chamber. The heating chamber heats a gas so as to sterilize the gas. The humidification chamber is adapted so that a liquid, which has been filtered by the filter, evaporates into the sterilized gas, thereby causing the sterilized gas to cool, and outputting a humidified gas at a desired temperature. The apparatus may include a bypass chamber to provide a path for the gas to bypass the humidification chamber. The apparatus may be adapted particularly for use in an incubator.

Provided is an air treatment apparatus comprising an air flow generator arranged to generate an air flow, a moisture source arranged to introduce water vapour into the air flow, a body that in use surrounds both air flow generator and the moisture source, and a water supply system arranged to provide water to the moisture source. The water supply system comprises a water tank assembly separable from the body, the water tank assembly comprising a water tank, a water supply pipe arranged to convey water from water tank, and an ultraviolet light source arranged to irradiate the water passing through the water supply pipe. The water tank comprises a tank opening and the water tank assembly further comprises a removable tank cap that is arranged to fit over the tank opening, with the ultraviolet light source and the water supply pipe being provided on the removable tank cap.

An air treatment device and a control method are provided. The air treatment device includes a water tank assembly, a water trough and a sterilization device. The sterilization device includes a sterilization portion, the sterilization portion is provided in the water trough, a water replenishing switch is provided between the water tank assembly and the water trough, and the water replenishing switch is configured to control connection and disconnection between the water tank assembly and the water trough. The air treatment device further includes a control portion, and the control portion is capable of controlling an opening and closing of the sterilization portion according to an on-off state of the water replenishing switch to ensure a good sterilization effect.

A sanitizing system for water treatment in appliances that use or that have an associated water cycle where sanitization of the water in the water cycle is beneficial. The system comprises a controller, a biocide, and a biocide injection subsystem, wherein the controller provides a signal to the injection subsystem to release a biocide into a water reservoir contained within the appliance, and further wherein the signal provided by the controller is in response to a signal received by the controller from the appliance.

This application relates to a humidifying device, including a shell, an air duct and an air blowing apparatus disposed in the shell, wherein a mist outlet channel, an atomizing cavity and a heating cavity communicated with the mist outlet channel are disposed in the shell; the air duct includes a first air duct communicated with the atomizing cavity and a second air duct communicated with the heating cavity; the air blowing apparatus is provided with an air outlet member, and the air outlet member is aligned with the first air duct and the second air duct, and is configured to supply a first air flow to the first air duct and supply a second air flow to the second air duct. When the humidifying device operates, the first air flow forms an atomized air flow and the second air flow forms a heated air flow then are mixed.
