The air conditioner includes a housing that has an inlet and an outlet for air that is to be supplied, a humidifying means for spraying humidifying mist into the air taken in through the inlet, and a vaporizing means for vaporizing unvaporized humidifying mist contained in the air into which the humidifying mist was sprayed by the humidifying means by causing the unvaporized humidifying mist to come into contact with the air flowing through the vaporizing means. The air subjected to humidity adjustment by the humidifying means and the vaporizing means is supplied to the paint booth via the outlet.

Provided is a humidifier, including a machine base, a water tank, a water suction pump, and a water inlet pipe. The machine base is located on the water tank, which includes an atomization water reservoir, a water feed base, a control base, an atomization air channel and an atomizer disposed inside. The water feed base includes a water feed opening and a first outflow opening, and the first outflow opening is in communication with the water tank; a water inlet is disposed on the atomization water reservoir, and water in the water tank will flow into the atomization water reservoir through the water inlet pipe by the water suction pump; the atomizer is in communication with the atomization water reservoir through an atomization opening disposed at the atomization water reservoir, and water vapor flows into the atomization air channel and flows to outside along the atomization air channel.

The present utility model provides an anti-drip rotatable sprayer, which is characterized in that: an inlet pipe and an outlet pipe are interconnected to pass through two opposite sides of the sprayer on the casing, the casing is provided with a reduction gear set driven by the driving shaft lever passing through the casing. The driving shaft lever passing through the casing is provided with a turntable, the inlet pipe passing through is provided with a nozzle to spray the water column towards the turntable, the turntable drives the reduction shaft lever and interlocks the outlet pipe to rotate on the casing. The sprayer is installed in a casing, the casing is provided with an external water source access passage for connecting the inlet pipe sprayer, and the casing is also provided with an outlet pipe through-outlet for passing through the outlet pipe of the sprayer. The outlet pipe after passing through the casing is connected to a spray head set, and the lower part of the casing is provided with a discharge outlet. The present utility model not only improves the overall spraying effect that the water mist after spraying the turntable is accumulated to form the water drips, and also it can be recycled.

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.

A humidifier is provided that typically includes a water filtration unit and a pump that draws filtered water from the water filtration unit, typically a carbon nanotube filter. The humidifier further includes a nozzle having an outlet orifice, wherein the nozzle is connected to the pump, where the pump forces the filtered water through the nozzle, thereby expelling the filtered water into an atmosphere in the form of a purified vapor or mist.

A mist generating device is provided with: a housing provided with a water tank; a shaft portion provided inside the housing; an impeller disposed so as to be rotatable in the horizontal direction with the shaft portion as the rotation axis; and a nozzle jetting the water in the water tank to the impeller. the water jetted from the nozzle collides with the impeller to thereby smash the jetted water to cause mist. The housing is provided with an outside air introducing port, which is provided with outside air introducing means for actively introducing outside air into the housing, the housing is provided with a mist releasing port, the mist releasing port is smaller in opening diameter than the outside air introducing port, and the inside of the housing can be pressurized by the active introduction of outside air into the housing by the outside air introducing means.

A cooling system including cooling unit having an electrical transformer, a control module, a water valve controlling water flow from a water source, a series of misting units, a delivery-unit, and a power supply. The delivery-unit is mounted proximal to condenser coils of an HVAC system. The delivery-unit delivers water to the series of misting units when activated. The misting units are configured to spray mist on the condenser coils of the HVAC system thereby lowering a temperature of outdoor air passing through the condenser coils and increasing efficiency of the HVAC system.

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.

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 water injector for an aviation cooling system includes a body having a first end, a second end, and an intermediate portion extending therebetween. A conduit extends through the body from the first end to the second end. A spray nozzle is fluidically connected to the conduit and arranged at one of the first end and the second end. A mounting plate is arranged at the other of the first end and the second end. The mounting plate is configured and disposed to secure the body to an aviation cooling component. A filter is supported at the body and is fluidically exposed to the conduit. The filter is configured and disposed to capture particulate flowing into the water injector towards the spray nozzle.
