Based on at least one of an operation mode input or the pollution level, the controller may operate one of (1) the first fan, (2) the first and second fans, (3) the first and second fans and the circulation fan, or (4) the second fan and the circulation fan.

An air cleaner is provided that may include a first air cleaning module having a first fan that generates air flow from a first suction inlet toward a first discharge outlet; a second air cleaning module having a second fan that generates air flow from a second suction inlet toward a second discharge outlet; a dividing plate provided between the first air cleaning module and the second air cleaning module; and a display provided at inside of the dividing plate and in which a light source is provided.

An air cleaner is provided that may include a first air cleaning module having a first fan that generates air flow from a first suction inlet toward a first discharge outlet; a second air cleaning module having a second fan that generates air flow from a second suction inlet toward a second discharge outlet; a dividing plate provided between the first air cleaning module and the second air cleaning module; and a display provided at inside of the dividing plate and in which a light source is provided.

An air cleaner is provided that may include a first air cleaning module having a first fan that generates air flow from a first suction inlet toward a first discharge outlet; a second air cleaning module having a second fan that generates air flow from a second suction inlet toward a second discharge outlet; a dividing plate provided between the first air cleaning module and the second air cleaning module; and a display provided at inside of the dividing plate and in which a light source is provided.

An air-conditioning apparatus (1), for treating air in enclosed environments, endowed with a constructive arrangement capable of absorbing vibrations of its inner components. The airconditioning apparatus (1) includes at least a cabinet (2), arranged to accommodate internal components of the apparatus (1), endowed with at least an outer face (4, 5, 6, 7). The apparatus (1) includes at least an absorber (3) capable of absorbing vibrations from internal components of the apparatus (1). The absorber means (3) is disposed tangentially to at least an outer face (4, 5, 6, 7) of the cabinet (2).

Air conditioner units are provided. An air conditioner unit includes an outdoor heat exchanger disposed in an outdoor portion, an indoor heat exchanger disposed in an indoor portion, and a bulkhead disposed between the outdoor heat exchanger and the indoor heat exchanger. The air conditioner unit further includes a pump disposed in the outdoor portion, and a conduit in fluid communication with the pump. The air conditioner unit further includes a receptacle disposed in the indoor portion, the receptacle in fluid communication with the conduit for receiving fluid from the conduit. The receptacle includes a tray defining a channel, and a riser extending from a bottom wall of the tray. The riser includes a raised surface disposed above the bottom wall along a vertical direction. A bore extends through and is defined in the raised surface and the bottom wall.

An air conditioner unit and methods of operating the same is provided. The air conditioner unit may include a refrigeration loop having a variable speed compressor, an electronic expansion valve, an indoor heat exchanger, and an outdoor heat exchanger. An indoor fan and an outdoor fan may be configured to urge air through the indoor and outdoor heat exchangers, respectively. A bulkhead may be disposed between the indoor heat exchanger and the outdoor heat exchanger to define an indoor portion and an outdoor portion of the unit. A vent aperture may be defined in the bulkhead, and the indoor and outdoor fans may be configured to urge make-up air from the outdoor portion through the vent aperture to the indoor portion. In addition, an auxiliary fan may be disposed within the vent aperture to provide additional boost make-up air, and a heating bank may be used to heat make-up air if desired.

Air conditioner units and bulkhead assemblies for air conditioner units are provided. A bulkhead assembly includes a bulkhead which includes a first sidewall, a second sidewall spaced apart from the first sidewall along a lateral direction, and a rear wall extending laterally between the first sidewall and the second sidewall. The rear wall includes an indoor facing surface and an opposing outdoor facing surface. The bulkhead assembly further includes a vent aperture defined in the rear wall, and a vent unit. The vent unit includes a frame, a door, and a hinge rotatably connecting the door to the frame. The frame is positioned on one of the indoor facing surface or the outdoor facing surface and defines a frame aperture generally aligned with the vent aperture. The door is rotatable between an open position and a closed position.

A window air conditioner is provided. The window air conditioner includes an air conditioner body; and a sealing plate assembly disposed at at least one side of the air conditioner body and including a fixed sealing plate group and a sliding sealing plate group connected with the fixed sealing plate group in a sealing manner, in which the fixed sealing plate group is disposed on a side wall of the air conditioner body, and the sliding sealing plate group is disposed at a side of the fixed sealing plate group away from the air conditioner body slidably in a direction approaching to or moving away from the air conditioner body.

Heating, ventilating and air conditioning are provided to a temporary, flexible shelter, especially in a rugged, remote and/or extreme environment, including locations and/or conditions where access to electric power may be limited and/or expensive. A portable system may include a light weight HVAC unit, with variable-speed components that are dynamically managed for efficiency, reliability and safety, and a flexible, self-insulating duct for connecting the HVAC unit to the temporary shelter.
