Systems and methods for evaporatively cooling air using a medialess cooling system. In one embodiment, a medialess evaporative cooling system comprises an enclosure, an air inlet that enables air to flow from an exterior of the enclosure to an interior of the enclosure, an air outlet that enables air to flow from the interior of the enclosure to the exterior of the enclosure, and an atomizer positioned within the enclosure, wherein the atomizer receives water from a water source and generates a mist of the water within the enclosure, and wherein air from the air inlet is passed through the enclosure and thereby cooled by evaporation of the mist, and the cooled air is provided at the air outlet.

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.

An adiabatic cooling system includes a condenser coil and one or more adiabatic pads positioned such that intake air for the adiabatic cooling system passes through the pads prior to contacting the condenser coil. The adiabatic cooling system includes a vibration device attached to each adiabatic pad. A controller is communicatively coupled to the vibration device for each of the adiabatic pads. The controller determines that cleaning of the adiabatic pads is needed. In response to detecting cleaning is needed, the controller causes the vibration device attached to each adiabatic pad to vibrate, thereby causing debris in the one or more adiabatic pads to become loosened and/or removed from the adiabatic pads.

A humidifier having a multiplicity of metallic flow plates and a multiplicity of water transfer membranes, in particular for humidifying process gas for an electrochemical system or for HVAC applications is described. The humidifier has a construction in which the metallic flow plates and the water transfer membranes are arranged such that in each case at most one of the single-layer flow plates is arranged between adjacent water transfer membranes of the stack; and at least one of the water transfer membranes is in each case accommodated in a sealing manner, in particular clamped in a sealing manner, between the mutually facing sealing lines of adjacent flow plates of the stack. The humidifier has lower production costs, greater efficiency and lower weight.

An apparatus for humidification of air to be delivered to a patient's airways may include a reservoir, and a humidifier chamber. The humidifier chamber may include a humidifier wick and a heating element for heating the humidifier chamber. The humidifier wick may comprise a fibrous sheet material. The humidifier chamber and wick may be vertically oriented in use such that a first end of the wick is above the second end of the wick. A deioniser may be provided to deionise the liquid prior to the humidifier wick. The apparatus may pasteurise liquid to be delivered to the humidification wick.

In the present disclosure, air passing through the inside of a humidifier is readily humidified. The humidifier includes a water chamber having a first circulation opening and a second circulation opening for allowing air to circulate. An outlet baffle that covers at least part of the second circulation opening from below is provided on an inner surface of a top cover of the water chamber. A third circulation opening is formed by the outlet baffle. The direction in which the third circulation opening opens intersects the direction in which the first circulation opening opens. A baffle protrudes from the inner surface of the top cover. The baffle is located on a straight path between the third circulation opening and the first circulation opening and extends in a direction that intersects the straight path.
