A modular high-efficiency particulate air (HEPA) filtration system includes first and second modular filtration units and a blower unit. The blower unit draws air from an isolated indoor space of a facility via a ventilation input to maintain negative air pressure within the isolated indoor space. The first modular filtration unit and the second modular filtration unit are connected in parallel with the ventilation input and the blower unit. The first modular filtration unit is disposed between the blower unit and the ventilation input and at least a portion of air drawn through the ventilation input by the blower unit passes through the first modular filtration unit, and the second modular filtration unit is disposed between the blower unit and the ventilation input and at least a portion of the air drawn through the ventilation input by the blower unit passes through the second modular filtration unit.

Disclosed is a powerless humidification module for an air cleaner which is capable of preventing leakage of water into the air cleaner. A powerless humidification module for an air cleaner which is detachably mounted on an upper portion of a body of the air cleaner and is capable of preventing leakage of water includes a base cover having a first opening opened toward the air cleaner and a second opening opened toward a side surface of the first opening, a cistern part located in the interior of the base cover and located such that a space defined between an inner partition wall and an outer partition wall having predetermined heights such that water supplied to one side thereof is stored surrounds a periphery of the first opening whereby water supplied to one side thereof is stored, and a humidification filter located in the second opening.

An air purifier includes a display mounted between a front panel of a cabinet of the air purifier and an upper panel of the cabinet. The front panel includes a door which is configured and supported to be drawn in to the cabinet toward the display or drawn out from the cabinet away from the display. A display module including the display is disposed below the upper panel.

An air purifying system includes first, second, and third air purifiers controlled independently and a docking station having first, second, and third supports configured to support and charge the first, second, and third air purifiers. The docking station has a vertical backbone, and the first, second, and third supports horizontally extend from the backbone. At least the second and third air purifiers are configured to be separated from the docking station and include handles to assist a user in transporting the second and third air purifiers to separate rooms or indoor spaces.

A temperature control (“TC”) unit and associated method for providing simultaneous independent temperature control of conditioned air to first and second rooms. The TC unit includes a cabinet. The cabinet may be divided into first and second compartments, the first compartment being adapted to receive and exhaust air from and to, respectively, the first room, and the second compartment being adapted to receive and exhaust air from and to, respectively, the second room. Sound dampening insulation may be positioned between the first and second compartments. First and second evaporators may be positioned within the cabinet so that: air from the first room passes through the first evaporator before exhausting back to the first room; and air from the second room passes through the second evaporator before exhausting back to the second room. The TC unit may be or include a vertical terminal air conditioning (“VTAC”) unit.

A floor-standing air conditioner indoor unit includes a main unit and a sub-unit detachably connected to the main unit. The main unit includes an indoor heat exchange module. The sub-unit includes an air treatment module configured to operate independently in a scenario that the sub-unit is separated from the main unit.

An air conditioner indoor unit is provided. The air conditioner indoor unit includes: a base module, having a base part which is arranged with a fan motor; a heat exchange module having a heat exchanger and a connection pipeline for connecting the heat exchanger to an air conditioner outdoor unit; the heat exchanger and the connection pipeline are arranged in such a way that in a mounted state, the heat exchanger and the connection pipeline are entirely located at a front side of the base module; an air and water duct module having an air duct assembly; the air duct assembly is suitable to be entirely disassembled from the base part without disassembling the fan motor in the base part. During mounting, pre-assembly is first performed and then general assembly is performed; in such manner, the time needed to assemble the whole unit may be reduced.

A climate control system coupled within an opening of a structure, with the opening separating an internal area within the structure and an exterior area external to the structure with the climate control system straddling the opening. The system consists essentially of: an interior unit disposed at the opening within the internal area; an exterior unit disposed at the opening in the exterior area; and a connector between the interior unit and the exterior unit that extends through the opening, the connector including: a circulation hose that extends through the opening to connect the exterior unit and the interior unit.

An air conditioner includes a main body including a body fan, a heat exchanger, and a body housing. A ventilation hose connects the main body to outdoor air. A ventilation module is attached to an outer side of the body housing, and includes a ventilation fan. The ventilation module switches between an exhaust mode in which indoor air is exhausted to the outdoors through the ventilation hose and an air supply mode in which outdoor air is supplied to the main body through the ventilation hose.

Some embodiments of the present disclosure provide an air conditioning system. The air conditioning system includes: a housing, having an indoor air supply port; a first heat exchanger, disposed in the housing, an air outlet of the first heat exchanger being communicated with the indoor air supply port; a first air supply mechanism, disposed in the housing, an air outlet of the first air supply mechanism being provided correspondingly to an air inlet of the first heat exchanger; and a plurality of replaceable assemblies, wherein each of the plurality of replaceable assemblies can be assembled in the housing, and the housing is selectively cooperated with one or more of the plurality of replaceable assemblies.
