An air treatment system comprises an air conditioner; a bipolar ionization assembly; and a power supply. The air conditioner may portable and include a wheeled housing; an evaporator or entry grill for ambient air; a condenser grill for hot air discharge; a cold air supply discharge grate; a motor; an evaporator coil; and an evaporator blower intake. The bipolar ionization assembly includes electrical leads, and is mounted by a bracket to the evaporator blower intake to position the electrical leads within the air stream of the evaporator blower intake. The power supply is operably connected to the portable air conditioner and to the bipolar ionization assembly. When mounted in the air conditioner, the bipolar ionization assembly creates an antimicrobial plasma capable of killing harmful pathogens including bacteria, mycoplasma, viruses, mold and odors, and reducing the presence of Volatile Organic Compounds (VOC's), particulates, and static electricity in the air.

A mobile air conditioner, comprising: a first heat exchanger, having a first interface and a second interface for a refrigerant to enter and exit; a phase-change energy storage heat exchange device, including a second heat exchanger and a phase-change energy storage working medium, wherein the second heat exchanger and the phase-change energy storage working medium may exchange heat therebetween, and the second heat exchanger has a third interface and a fourth interface for the refrigerant to enter and exit; a first refrigerant pipeline, connected to the first interface and the third interface; and a second refrigerant pipeline, connected to the second interface and the fourth interface.

Providing simultaneous independent temperature control of conditioned air to first and second rooms. First and second evaporators may be positioned 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.

An air treatment device includes: a casing having an inlet through which air is drawn, and an outlet out of which the air drawn through the inlet is blown; a blade configured to adjust a direction of the air blown out of the outlet; and a generator configured to generate an antimicrobial element that sanitizes the blade. The blade has a first surface, and a second surface opposite to the first surface. The blade is shiftable between a first position in which the antimicrobial element is provided to the first surface and a second position in which the antimicrobial element is provided to the second surface.

A portable air cooler is fashioned as a storage chest for ice cubes, dry ice, or other pre-chilled articles such as reusable freezable blocks. Sidewalls of the chest include air intakes, and a baffle forces intake air to pass by or through the chilled articles to that the air is cooled by heat exchange. Fans in the chest lid exhaust the cooled air, which may be used to cool waste heat from a heat-producing device lain atop the chest. The lid also includes stand-offs to allow airflow under the device being cooled, and guardrails help maintain the device in position over the fans providing cooling air and prevent the device from being casually knocked off the top of the lid of the chest.

The present invention discloses a base unit and a desktop cooling fan having the base unit, wherein the base unit comprises a base for detachably carrying a front panel unit, and/or a cooling unit, and/or an air supply unit mounting part, and/or a cover unit, and/or a refrigerant unit, and the base is formed with a lower liquid storage tank structure which can be closed. This freely disassembled and assembled structure provides flexible and convenient use performance. Meanwhile, the cooling device provided also effectively overcomes the problems of easy discoloration, aging, high noise, easy overflow of a refrigerant medium in use of the wet curtain of the existing apparatus.

An embodiment provides an air conditioner, including: an outer housing that contains therein one or more of a condenser, a compressor, coils, a fan, an enclosure air intake, and an enclosure air return; one or more rainwater drains configured to transmit rainwater that enters the housing through the outer housing to ambient; and one or more condenser drains configured to transmit condensation from within the outer housing to an exterior location via one or more conduits.

An air conditioner unit may include a housing, an outdoor heat exchanger assembly, an indoor heat exchanger assembly, a compressor, and a sterilization light assembly. 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 outdoor heat exchanger assembly may be disposed in the outdoor portion and include an outdoor heat exchanger. The indoor heat exchanger assembly may be disposed in the indoor portion and include an indoor heat exchanger and an indoor fan. The compressor may be in fluid communication with the outdoor heat exchanger and the indoor heat exchanger to circulate a refrigerant between the outdoor heat exchanger and the indoor heat exchanger. The sterilization light assembly may be disposed within the indoor portion and directed at the indoor fan to transmit an ultraviolet light emission thereto.
