An air conditioner unit may include a housing, an outdoor heat exchanger, an indoor heat exchanger, a compressor, a sterilization light assembly, and a controller. The controller may be configured to initiate a sterilizing operation. The sterilizing operation may include receiving a first command signal and directing activation of the sterilization light assembly at a first active intensity level for transmission of ultraviolet light emissions within the indoor portion in response to receiving the first command signal. The sterilizing operation may further include receiving a second command signal following the first command signal and directing activation of the sterilization light assembly at a second active intensity level for transmission of ultraviolet light emissions within the indoor portion in response to receiving the second command signal. The second active intensity level may be different from the first active intensity level.

An indoor unit apparatus of a split-type air conditioner and a method for using the same are provided, which can realize both of an impinging jet ventilation manner and a displacement ventilation manner. A thin air layer can be formed on the ground through using the indoor unit apparatus of a split-type air conditioner, and the indoor unit apparatus of a split-type air conditioner is adapted to be used both in summer and in winter.

An antibacterial device that includes a substrate, a first electrode on the substrate, a second electrode on the substrate, and a protective layer covering the first electrode and the second electrode and having a first surface opposing of the substrate and a second surface opposite the first surface. Further, the first electrode and the second electrode are arranged such that the protective layer has an electric field strength on the second surface thereof of 150 kV/m or more when a voltage is applied to the first electrode or the second electrode.

An ion generator, a fan coil unit and an air conditioning system. The ion generator includes: a power module; a negative plate connected to the power module; a ground plate spaced apart from a first side of the negative plate, the first side of the negative plate includes a plurality of plasma needles extending toward the ground plate; a positive plate spaced apart from a second side of the negative plate, the positive plate is connected to the power module and has a polarity opposite to that of the negative plate, and the respective sides of the negative plate and the positive plate that are facing toward each other are respectively provided with a plurality of carbon fiber brushes at corresponding positions.

A method and apparatus for an inline air purification system is described herein. An example apparatus includes a housing, a high-velocity air flow guide, a filter assembly, and a fan. The high-velocity air flow guide includes a first portion and a second portion. The first portion is configured to form a passage within the housing, and the second portion is configured to divert and accelerate air flow of the ambient air from the passage to a chamber of the housing. The filter assembly includes one or more filtering elements configured to receive the ambient air from the chamber. The fan is configured to draw the ambient air from the chamber through the filter assembly and to generate processed air from the ambient air. The housing is located in an HVAC duct, and occupies only part of the cross-sectional area of the duct. The remaining area of the duct accommodates bypass air flow to a primary fan in the HVAC system.

An air conditioner includes a dust collection sheet including a first electrode and a second electrode separated from the first electrode and facing the first electrode, and to collect particles in air, a power supplier electrically connected to the first and second electrodes, and a controller configured to control the power supplier to apply a direct current (DC) voltage to the first electrode to perform a dust collecting operation, determine to perform at least one of a first sterilizing operation at a preset first temperature for a first period of time and a second sterilizing operation at a second temperature higher than the first temperature for a second period of time shorter than the first period of time, and control the power supplier to apply an alternate current (AC) voltage to the first electrode and the second electrode for the first sterilizing operation or the second sterilizing operation.

An air conditioner capable of efficiently collecting foreign substances in the air is disclosed. The air conditioner includes a cabinet, an air blower disposed in the cabinet to cause air to flow, a dust collector case forming a channel for the air caused to flow by the air blower, at least one electrode provided in the dust collector case and formed of carbon fibers to generate ions, and a charged dust collecting filter to collect foreign substances charged by ions generated by the electrode.

An improved high-efficiency electrostatic air filter device implements a dust collection function and incorporates a material that captures and that is toxic to viruses/bacteria and causes viruses and bacteria to be rendered harmless by contact with this material. The device is composed of a charging section having a conductive antiviral media to charge any particles in the gas with a high electric voltage and a collecting section which contains or is composed of conductive material which has antiviral/antibacterial properties and a surface of opposite polarity or lower potential that will cause the aforementioned charged particles to adhere to the toxic material as the gas flows through or around the media. The collection section is formed with or coated by an inactivating material that inactivated pathogens when physically contacted.
