An air conditioner device having a housing or duct with an opening for exit of air and one or more rotatable flaps for adjusting air flow rate and angle exiting through the opening. An ionizer having an electrode is configured to ionize air exiting through the opening, and a cleaning pad is adapted to frictionally remove debris from the electrode consequent to rotation of the flaps without requiring manual operation by a user.

An air conditioning device includes an air purifier, a sensor, a communicator, and a processor. The sensor is configured to measure an air pollution level. The communicator comprises circuitry and configured to communicate with a server. The processor is configured to activate the sensor in a state where the air purifier is not driven, in response to receiving a first signal requesting an air pollution level state information from the server based on a location of a mobile terminal, transmit a second signal indicating that the air conditioning device needs to be driven to the server based on the air pollution level measured by the sensor, and drive the air purifier in response to a driving instruction received from the server.

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.

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.

A fan coil apparatus for a closed greenhouse that recirculates are within the greenhouse includes a housing with an intake and an outtake further including a filter that filters recirculating air that enters the intake, cooling coils that cool the recirculating air and condense water therefrom, heating coils that heat the recirculating air, a sterilization system that kills and prevents the spread of airborne pathogens, and a fan that directs the recirculating air through the outtake outside the housing.

An air conditioner is provided that may include a main body having an air inlet and an air outlet; a filter received in the main body to filter air; a heat exchanger configured to allow heat exchange between a refrigerant and air suctioned into the main body; and a lamp module configured to radiate ultraviolet (UV) rays and infrared (IR) rays to the heat exchanger. The lamp module may include a porous main body, a plurality of UV lamps, and a plurality of IR lamps. The plurality of UV lamps and the plurality of IR lamps may be arranged in parallel on one surface of the porous main body at predetermined intervals.

An electric dust collecting device according to the invention includes an electric charging unit for electrically charging dust in air, a first filter unit including a plurality of discharge electrode plates spaced apart from each other to define passages therebetween through which dust electrically charged by the electric charging unit passes, and a second filter unit disposed downstream of the plurality of discharge electrode plates in an air flow direction and connected to a ground to cause corona discharge between the plurality of discharge electrode plates and the second filter unit and to collect electrically charged dust. Dust particles electrically charged by the electric charging unit pass through the passages of the first filter unit and then are collected at the second filter unit, and dust particles electrically charged between the first filter unit and the second filter unit are electrically charged by the second filter unit, thus improving electric charging efficiency and dust collecting efficiency.
