An inductive-humidification and evaporative-cooling ventilation system comprising: means for generating a flow of air; a channel for conveying said flow of air, said channel comprising a plurality of inductive holes for transferring said flow of air into the environment, said channel further comprising at least one outflow mouth for expelling said flow of air, which has a three-dimensional structure open both at the back and at the front, and a fluid-thread straightener set at the rear end of said at least one outflow mouth, which recalls a flow of air from the environment surrounding said channel; and at least one humidification device for introducing nebulised water into the environment; wherein said at least one humidification device is set within said at least one diffusion mouth, and said plurality of holes are arranged in a number of rows aligned longitudinally along the ducts.

A dry fog diffuser comprises a support. A shroud is mounted to the support. The shroud comprises a tubular elbow having an inlet end and an outlet end. The shroud is mounted with a long side of the elbow including a drain port facing downward. An atomizing nozzle is mounted at the inlet end of the elbow and aligned with an axis of the elbow at the inlet end. The nozzle is connected, in use, to a water supply and an air supply. The diffuser produces a dry fog exiting shroud at the outlet end of the tubular elbow.

The disclosure is related to a blowing apparatus with expandable functions, an expansion device, and an operating method. The blowing apparatus has an electrical interface used to connect one of the expansion devices with various functions. The blowing apparatus has a control unit used to identify an operating mode of the expansion device connected with the blowing apparatus. A control signal is therefore generated. According to the control signal, the control unit controls rotating speed of a fan unit and a heating temperature of a heating unit. The expansion device can be disposed with a mist unit having a container and a mist generating unit. The mist unit sprays the mist to an outlet cap of the expansion device. The blowing apparatus then blows the mist out of the outlet cap by means of the rotating speed of fan unit and the temperature of heating unit.

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.

The present invention provides a potable pneumatic atomizing device. It includes a mounting seat, a small type fan, a water tank, an ultrasonic atomizing piece and a fixing clip. The small type fan and the water tank are respectively installed on the upper part and the side part of the mounting seat, and an air passage is formed among the small type fan, the water tank and the mounting seat; the mounting seat is provided with a lifting support frame, the lifting support frame stretches the clothes to extend the gap between the clothes and the human body. The ultrasonic atomizing piece is arranged on the top of the water tank and atomizes water in the water tank to release into the gap between clothes and the human body. The small type fan transfers outside air into the air passage, then passing the air passage, into the gap.

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.
