An evaporative air cooler is described. The evaporative air cooler includes a housing defining an interior of the evaporative air cooler; a tank positioned adjacent to a top portion of the housing, wherein the tank is configured to receive, store, and release liquid; a mister in fluid communication with the tank, wherein the mister is configured to create a mist from the liquid; a filter structure with a filter, wherein the filter is configured to absorb the mist; a fan configured to draw the air into the interior, wherein the air is cooled by at least one of the mist and the filter, and wherein the fan directs the air through the filter structure and from the interior; and a clip coupled to the housing.

An apparatus, system, and method for providing a non-linear fluid stream into an environment for cooling purposes are disclosed. Such an apparatus includes a body portion and a nozzle, the nozzle being adapted to direct water into the environment. Such an apparatus may include a body portion having a flow channel defined therein for gas flow therethrough; and, a nozzle operatively disposed within the flow channel; said nozzle adapted to direct a liquid therefrom; wherein the channel and the nozzle are operatively disposed relative to each other so that a gas flowing through the channel and the liquid are combined into a fluid stream directed from the apparatus into the surrounding environment.

Space purification device according to the present disclosure includes hypochlorous acid water generator, mixing bath, hypochlorous acid water supply unit, water supply unit, humidifying purification unit, and control unit. Control unit is configured to, after a humidifying purification operation using the mixture water has finished, perform a first washing operation of causing water supply unit to supply water to electrolytic bath and of causing hypochlorous acid water supply unit to supply water stored in electrolytic bath to mixing bath, without performing the electrolyzing.

A portable misting fan in which the user controls the spray mist and the fan operation separately. A lower compartment stores a fluid and a pump provides the pressure to propel the fluid through a delivery tube to a spray nozzle. The flow of fluid to the nozzle is controlled by a valve that is operated by the user pushing a button. An upper compartment houses a fan which is powered by batteries and provides an air stream that is directed to the user. The fan is mounted in a fan housing in the upper compartment that is pivotally connected to the upper housing. There axe passageways in the fan housing and pivot connection for receiving the fluid delivery tube and electrical wires so that all they are all internal to the misting fan.

A system for purifying and pre-conditioning intake air in an air conditioning unit comprises an energy exchange unit having an air inlet, an air outlet, a primary air flow running from the air inlet to the air outlet, and an active energy exchanging element or elements, and at least one spray washer having at least one nozzle, the spray washer positioned between the air inlet and the next active element, wherein the at least one spray washer is configured to dispense droplets of a fluid into the intake air from the at least one nozzle. A method for purifying and pre-conditioning intake air in an air conditioning unit is also described.

A humidification system including a water-delivery system, an air-delivery system, a control system, and at least one fog-generation system. In example forms, the system includes a water-and-air delivery bar, a fog-delivery block, and/or a tubing-and-track delivery system. In another example form, a humidification system includes a housing having a nozzle discharge body, an air inlet coupling having an air delivery conduit extending therethrough, and a water inlet coupling having a water delivery conduit extending therethrough, and further including means for providing heating and/or a consistent back-pressure and flowrate across multiple nozzles in a multi-nozzle array.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes a water tank storing water; a visual body forming at least a portion of the water tank and formed of a transparent material; a watering housing disposed in the water tank, drawing water stored in the water tank to pump water to an upper side, and spraying the pumped water; a nozzle disposed in the watering housing and spraying the pumped water; and a watering motor rotating the watering housing. Here, when the watering housing rotates, water sprayed from the nozzle forms at least one spray line on an inner side surface of the visual body.

A humidification and air cleaning apparatus including a water tank; a transparent body forming at least a portion of the water tank; a watering housing disposed in the water tank to spray water stored in the water tank; a nozzle disposed in the watering housing to spray the pumped water; an air wash inlet disposed in the water tank to receive external air into the water tank; and an air wash inlet disposed in the water tank to discharge internal air out of the water tank. During rotation, the sprayed water forms a certain trajectory and collides with an inner side surface of the visual body. Air flowing outside the water tank forms an outer main stream before passing the air wash inlet. Air passing the air wash inlet forms an inner main stream inside the water tank, which passes the trajectory of sprayed water to the discharge port.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes a water tank storing water; a visual body forming at least a portion of the water tank and formed of a transparent material; a watering housing disposed in the water tank, drawing water stored in the water tank to pump water to an upper side, and spraying the pumped water; a nozzle disposed in the watering housing and spraying the pumped water; and a watering motor rotating the watering housing. Here, when the watering housing rotates, water sprayed from the nozzle forms at least one spray line on an inner side surface of the visual body.

Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes: a water tank storing water; a visual body coupled to the water tank, disposed over the water tank, and formed of a transparent material; a display module disposed outside the visual body; and a watering housing disposed in the water tank and having a nozzle to spray water. Here, water drops, formed on an inner side surface of the visual body, and the display module are disposed on an eye line of a user.
