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.

Systems and methods for dispensing compositions, such as beverages, are provided. A beverage dispenser may be configured to receive input corresponding to a selection of a beverage, and in response, a graphical representation of the beverage at a display device. The beverage dispenser may receive additional input corresponding to an adjustment of an amount of an ingredient of the selected beverage, and in response, the graphical representation of the beverage may be updated. The graphical representation of the beverage may include graphics depicting the beverage container, the volume of liquid in the beverage container, and the adjusted ingredient.

A humidification and air cleaning apparatus is provided that may include a lower base, a lower housing, a plurality of legs, a leg wall, and an input assembly. The lower base may be supported by an installation surface. The lower housing may be spaced apart upwardly from the lower base and form a suction gap by being spaced apart from the lower base. The plurality of legs may be disposed on at least one of the lower base or a lower housing. The plurality of legs may support the lower housing. The leg wall may connect two adjacent legs to each other. The input assembly may be disposed at the lower housing. The input assembly may protrude toward the suction gap. The input assembly may receive a wireless signal. The plurality of legs may include a first leg and a second leg adjacent to each other. The input assembly may be disposed outside of the leg wall. As an input assembly receiving a voice signal is exposed to the outside, a user's voice may be effectively recognized. Further, as the leg wall is disposed between the input assembly and the lower housing inlet, it is possible to suppress propagation of operating noise generated by a blowing unit to the input assembly.

Methods and apparatus for vaporizing liquid from a liquid source into the surrounding environment, are disclosed, where the apparatus comprises at least one manifold comprising at least one liquid port formed by a through-hole and at least one ridge structure, wherein the liquid port is in fluid communication with the liquid source and the one ridge structure At least one vaporization port is included in a planar structure connecting a first side of the structure to a second side, in fluid communication with the at least one ridge structure and the surrounding environment, wherein fluid flow through the liquid and vaporization ports is substantially perpendicular to the plane of the structure, and the ridge structures are substantially parallel to the plane of the structure. At least one heating element is present that is in thermal communication to the at least one vaporization port and at least one ridge structure.

The installation means for a device for treating, in particular humidifying and/or cleaning, a net fluid, in particular a gas, by means of a working fluid, in particular a liquid, and particularly for cooling water vapor by means of spray water and/or drip water, is provided with at least one installation package (10) of several square, waved mat elements (12) being arranged in an overlying or adjoining manner Adjacent mat elements (12) are mechanically connected to each other by pin-hole-arrangements in which pins (42) protruding from the one mat element (12) and each comprising a free end are inserted in receiving openings (34) formed in the other mat element (12). The receiving openings (34) each comprise an opening edge (36) from which a flexible clamping tongue (38) protrudes into the receiving opening (34). Each receiving opening (34) comprises an area size limited by the free end of the at least one clamping tongue (38) and the region of the opening edge (36) opposite to said end, or by the free ends of several, in particular two or three clamping tongues (38), wherein the area size (40) being smaller than the cross-section of the pin (42) in the state of the pin (42) in which the pin (42) is received by the receiving opening (34), and in which the at least one clamping tongue (38) is bend with its free end to the free end of the pin and abuts against the pin (42).

An HVAC system includes an indoor heat-exchange coil disposed between a supply air duct and a return air duct. A damper is disposed in a re-circulation duct and is moveable between an open position and a closed position. A controller is configured to determine if the HVAC system is operating in a heating mode or an air-conditioning mode. Responsive to a determination that the HVAC system is operating in the air-conditioning mode, the controller is configured to determine if the variable-speed indoor circulation fan is operating at a minimum speed and if the relative humidity measured by the humidity sensor is above a pre-determined threshold. Responsive to a determination that the variable-speed indoor circulation fan is operating at the minimum speed and the relative humidity of the enclosed space is above the pre-determined threshold, the controller signals the damper to move to the open position.

There is provided an air treatment apparatus comprising an evaporative humidifier comprising an evaporator assembly. The evaporator assembly comprises an arrangement of spacer fabric that is multi-layered, and an evaporator frame that supports the arrangement of spacer fabric, wherein the evaporator frame comprises at least one of an outer grille that surrounds an outer surface of the arrangement of spacer fabric and an inner grille that extends over an inner surface of the arrangement of spacer fabric.
