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 housing may define an indoor portion and an outdoor portion. The housing may further define an exhaust outlet downstream from the indoor portion to exhaust air therefrom. The sterilization light assembly may be disposed within the indoor portion. The controller may be in operable communication with the indoor fan and the sterilization light assembly. The controller may be configured to initiate a sterilizing operation. The sterilizing operation may include directing activation of the indoor fan to motivate air through the indoor portion, detecting activation of the indoor fan to motivate air through the indoor portion, and directing activation of the sterilization light assembly to transmit an ultraviolet light emission within the indoor portion based on detected activation of the indoor fan.

In an embodiment, a portable cooling device comprises a duct having two ends at opposing sides. An end is adapted for air intake while an opposing end is adapted for air expulsion. A fan is positioned within the duct and in communication with a motor. Further, a heat sink is positioned within the duct comprising adapted to receive a cooling pod insertably mounted in a central through-hole of the heat sink. The cooling pod is removable and replaceable. The motor is in communication with a power source. In an embodiment, a solar panel is positioned on the duct providing auxiliary power to the power source. Each end of the duct comprises an aperture each adapted to receive an air intake grate and air expulsion grate.

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.

An air handling system comprising a base (5) and one or more air handling devices (2, 3, 4) disposed on the base (5), wherein each of the air handling devices (2, 3, 4) comprises an air inlet (431), an air outlet (432), and a power-supply structure; and the base (5) comprises an air inlet, an air outlet, an external power source, and a power-supply output structure for powering the adjacent air handling device (4).

Air disinfection/sterilization device and group is described conveniently usable for the disinfection/sterilization of air conditioning systems, comprising: an air conditioner comprising an internal unit comprising an outlet mouth, crossed by air in output from the internal unit and an inlet mouth crossed by air in input from the internal unit; a disinfection/sterilization device comprising: a boxed longitudinal frame, extending longitudinally along the length of the outlet mouth or the inlet mouth of the air conditioner; disinfection/sterilization means, adapted to purify air in output from the outlet mouth and/or in input from the inlet mouth; the disinfection/sterilization means comprise at least one IIV-C type LED; means for coupling the boxed longitudinal frame to the air conditioner and means for coupling the boxed longitudinal frame to the air conditioning system; the means for coupling the boxed longitudinal frame to the air conditioner comprising gluing and adhesive tapes used to anchor the boxed longitudinal frame near the outlet mouth or the inlet mouth of the air conditioner and, further, to an air conditioning duct which is afferent to air intake and/or exhaust vents.
