An air-conditioning system is provided that may include a first air-processing apparatus, which includes a first outlet formed to be open toward a floor and a first inlet formed to be open in a direction inclined relative to a direction in which the first outlet is open and is configured to deliver heat-exchanged air to the first outlet, and a second air-processing apparatus, which includes a second outlet formed to be open in a direction parallel to the first outlet and a second inlet formed to be open in a direction parallel to the first inlet and is configured to deliver purified air to the second outlet. The first outlet and the second outlet extend in a lateral direction, and the first air-processing apparatus and the second air-processing apparatus are arranged in the lateral direction.

An air-conditioning system is provided that may include a first air-processing apparatus, which includes a first inlet formed in a first surface thereof that extends perpendicular to a floor or a ceiling and a first outlet formed in a second surface thereof perpendicular to the first inlet and induces air introduced into the first inlet to exchange heat with refrigerant and to be discharged through the first outlet, and a second air-processing apparatus, which includes a second outlet formed therein so as to be open in a same direction as the first outlet and a second inlet formed therein so as to be open in a same direction as the first inlet. The air-conditioning system may be driven in a combined operation mode in which the first and second air-processing apparatuses operate simultaneously or an independent operation mode in which one of the first air-processing apparatus or the second air-processing apparatus operates.

A hydro-enhanced air cleaner is provided as a stand-alone unit or as a component of a heating, ventilation, air conditioning system for a building which cleans and purifies ambient air and is also capable of producing potable water in humid environments. The device includes a dehumidifier which extracts polluted humid air and produces condensate including water and pollutants which adhere to the water. A degasser is connected with the dehumidifier to purify and degas the condensate to produce deionized water and pollutants. A humidifier is connected with the degasser to vaporize at least a portion of the deionized water for delivery to a living space. Excess deionized water may be collected as a potable water supply. In accordance with a method, the apparatus is used to continuously recycle air within a building further continuously clean the air.

An exhaust and filtration assembly includes: a housing; an exhaust vent configured to guide unfiltered air out of the exhaust and filtration assembly; a filter assembly configured to filter air and guide the filtered air out of the exhaust and filtration assembly; an exhaust assembly configured to direct raw air from an entry port of the exhaust and filtration assembly and direct air out of the exhaust vent without the air having been filtered; and a controller comprising computing logic configured to control so that only one of air filtration and raw air exhaust occurs at any given time.

A cooling electronic cabinet assembly includes a cabinet that has a plurality of storage compartments that is each defined within an interior of the cabinet to store an electronic device. The cabinet has a plurality of air holes each being integrated into the cabinet. A plurality of blowers is each coupled to the cabinet and each of the blowers is aligned with a respective air hole. Each of the blowers urges air in a first direction when the blowers are turned on to urge the air over the electronic devices in the cabinet for cooling the electronic devices. A plurality of filter housings is each coupled to the cabinet and each of the filter housings is aligned with a respective one of the air holes. A plurality of filters is each of the filters is removably insertable into a respective one of the filter housings to filter particles from the air is blown through the filters.

An indoor pollution prevention system includes a plurality of gas detection modules, one or more intelligent control-driving processing devices, one or more gas-exchange processing devices, one or more intake passages, and one or more discharge passages. The intake passage is connected to the gas-exchange processing device and has an intake opening for guiding the outdoor gas into an indoor space. The discharge passage is connected to the gas-exchange processing device and has a discharge opening for discharging the air pollution source to the outdoor space. The intelligent control-driving processing device controls the gas-exchange processing device to be enabled under a surveillance condition of the gas detection module, so that the air pollution source passes through the discharge passage, filtered and purified by a cleaning and filtration assembly, and is discharged to the outdoor space, thereby allowing the indoor space to have a clean air.

Air purification devices include an air inlet and outlet, upstream and downstream sections in air flow communication with the air inlet and outlet and a filter removably positioned between the upstream and downstream sections to filter at least pathogens from air being passed through the filter. One or more ultraviolet (UV) illuminating sources may be positioned in at least the upstream section proximate the filter to illuminate at least an upstream surface of the filter with sufficient UV radiation to kill viable pathogens that accumulate on the filter. One or more ozone generating sources may be positioned to generate ozone in sufficient concentrations to kill viable pathogens proximate the device. The UV illuminating sources and ozone generating sources may be positioned to provide a predetermined pressure drop across the sources and air flow pattern proximate the filter, and enable the filter to be removed without handling the sources.

Air diffusion terminal apparatus (1) for wall or ceiling (33), fluidly connectable to an air ventilation system (3), comprising: a frame (4) comprising a framework (8,9) and a through-hole (35), the framework (8,9) being configured to be installed and housed in a cavity of the wall/ceiling (33); a cartridge (5) configured to be insertable in the frame (4) according to a first direction (F) parallel to a longitudinal axis (L) of the through-hole (35) so to fill the through-hole (35) of the frame (4); said cartridge (5) comprising a plurality of housings (6) for receiving respective modules (7), said modules (7) comprising at least an air diffusion module in turn comprising deflecting blades (7A,7B,7C) or a plate (7D) provided with holes (7E) or nozzles (7F).

An air filtration system is disclosed. The system comprises an air conduit having an inlet and an outlet, a self-contained electric power source, an electrically powered fan, an air filter located transversely across said air conduit, and an air boundary containment nozzle at the outlet of the air conduit. The nozzle has an outlet diameter of between about 0.5 centimeters and about 4 centimeters. The nozzle minimizes the mixing of the unfiltered ambient air with the filtered air directed to the wearer.
