The casing includes an air inlet and an air outlet. The water mesh includes multiple orifices and is accommodated between the air inlet and the air outlet of the casing. The water distribution seat is secured on a top of the water mesh and includes an aperture and multiple passages. The water collection device communicates with a bottom of the water mesh, and the water collection device includes a water accommodation chamber and a pump, wherein the pump has a water output segment connecting with a guide tube which communicates with the aperture of the water distribution seat, such that the water is outputted by the pump to flow toward the aperture via the guide tube.

The purpose of the present invention is to provide a condensing boiler employing an eco-friendly evaporation device, in which condensed water generated in a latent heat exchanger is removed by using the evaporation device, so that the condensing boiler can be installed in a site without a processing facility for discharging condensed water and contribute to energy saving. For implementation thereof, the present invention comprises: a blower (110) for supplying a supply-air; a sensible heat exchanger (140) for absorbing combustion sensible heat generated in a combustion chamber (130) by combustion by a burner (120); a latent heat exchanger (150) for absorbing latent heat of steam included in combustion gas which has finished heat exchange in the heat sensible exchanger (140); and an evaporation device (160) which absorbs condensed water generated in the latent heat exchanger (150), and has an evaporation type humidifier (161) for evaporating and removing the absorbed condensed water by using air supplied from the blower (110).

Cooling units are provided. The cooling units include a base having a housing with control components and a cooling tower attached to the base and having an inner flow path and an exterior surface. An air distribution system is attached to the cooling tower and includes an air distribution chamber defined between first and second enclosures, air dispensers are configured in the first enclosure, and a cover is disposed on an exterior surface of the second enclosure. The control components are configured to convey air through the base, the cooling tower, and the air distribution system to dispense air through the cool air dispenser and the warm air dispenser. A cooling unit water supply is arranged to provide cooling water to the air distribution system through the cooling tower and a water treatment module connected to the cooling unit water supply to treat the cooling water.

A humidifier has a base and a housing. The housing has a steam exhaust vent and a vaporizer. The vaporizer includes a heating element surrounded by a removable porous sleeve that protrudes downwardly into water within a reservoir of the base. The sleeve wicks the water including its minerals and impurities into contact with the heating element wherein energization of the heating element causes the wicked water to convert to steam that rises through the exhaust vent and from the housing during a humidification mode.

A humidifier with regular addition of fixed quantity of essential oil is located in public areas and configured such that humidified air contains fragrance regularly. The humidifier is provided with a main body, water storage bucket mounted to the main body, and essential oil supplier mounted to the main body. The essential oil supplier includes a casing, at least one essential oil bottle within the casing and stored with essential oil, at least one peristaltic pump corresponding to each bottle and connected to the main body to be controlled. Each peristaltic pump is controlled by the main body, such that fixed quantity of essential oil is supplied regularly by the humidifier with the water storage bucket being not dismounted to keep fragrance in atomizing air continuous and eliminate the problem of only presence of fragrance at the beginning of addition of essential oil due to conventional method of addition.

A filter cartridge for filtering water, for use in an air humidifier, having a storage chamber for storing filter material, and having at least one opening for feeding to the storage chamber and/or for releasing from the storage chamber the water to be filtered is proposed. For the purpose of relatively quick filling, the filter cartridge is formed to be arranged in a container, containing water to be filtered, such that the filter cartridge can project at least partially into the water stored in the container, with the at least one opening formed both as a water inlet for feeding water from the container into the storage chamber and as a water outlet for discharging water from the storage chamber into the container. A roller, an air humidifier and a filtering method are also proposed.

A wet-pack assembly includes a water panel, a scale control configured to surround the water panel on at least three sides, and a distribution tray disposed on a top portion of the water panel and coupled to the scale control via one or more joints. The one or more joints prevent separation of the distribution tray from the scale control. The wet-pack assembly also includes a feed tube extending from a basin formed within the scale control to the distribution tray, where the feed tube is structured to direct water flow from the basin to the distribution tray for recirculation to the water panel.

The invention relates to a humidifier (10) for a test chamber, in particular a climate chamber or the like, as well as to a method for conditioning air of a test space of a test chamber, said humidifier comprising a container (11) having a container interior (12) for receiving a water bath (13), a heating device (15) of a temperature-control system (14) for controlling the temperature of the water bath, and a ventilation system (17) for generating air bubbles (18) in the water bath, a container opening (28) being formed in the container above the water bath in order to connect the container interior to a test space of a test chamber, said humidifier comprising a cooling device (16) of the temperature-control system.

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.

There is provided an air treatment apparatus comprising a body, an air flow generator housed within the body that is arranged to generate an air flow, an evaporator assembly removably disposed within the body and that is arranged to introduce water vapour into the air flow, and a water supply system that is arranged to provide water to the evaporator assembly. The water supply system comprises a water tank assembly that is separable from the body, the water tank assembly comprising a water tank having a tank opening. The tank opening is configured to allow the evaporator assembly to fit through the tank opening and the evaporator assembly is configured to fit within an interior volume of the water tank.
