The bulkhead assembly further includes a drive assembly connected to the vent door and operable to selectively move the vent door between the open position and the closed position.

Various air conditioner systems and methods are presented. An air ventilation chamber assembly may include a first chamber and a second chamber through which air is circulated into an environment to be cooled. A cooling element of a heat pump, may pass through the first chamber of the air ventilation chamber assembly, wherein the cooling element does not pass through the second chamber of the air ventilation chamber assembly. A Peltier cooler may be present that has a cold side and a hot side. The cold side may be is thermodynamically coupled with a surface of the second chamber.

A set for assembling a heat source unit of an air conditioner at the site of the air conditioner, includes a heat source heat exchanger module having a first casing, a heat source heat exchanger and a compressor module port fluidly communicated with the heat source heat exchanger, a compressor module having a second casing separate from the first casing, a compressor and a heat source heat exchanger module port fluidly communicated with the compressor, wherein the heat source heat exchanger module and the compressor module are fluidly communicatable via the compressor module port and the heat source heat exchanger port, a main board comprising a control logic of the air conditioner and a first electric connector, wherein at least one of heat source heat exchanger and compressor modules has a circuit board comprising a second electric connector, the circuit board of such a module being configured for data communication with the main board upon electrical connection of the circuit board and the main board via the first and second connectors. Further, a method for assembling a heat source unit of an air conditioner at the site of the air conditioner uses such a set.

An adjustable bar window lock is a straight bar with a foot at each end, and a snap-locking buckle in the center wherein the two double hung halves of the bar are able to be adjusted incrementally and solidly locked at a preferred length to lock a double hung window in a partially opened position against a window cooling unit to prevent removal or access to the interior of the home.

Various embodiments of air conditioner units are detailed. Such air conditioner units may use multiple air ventilation chambers arranged on both an indoor and outdoor portion of the air conditioner unit. A through-unit window may be present that permits an unobstructed view through the air conditioner unit between the first air ventilation chamber and the second air ventilation chamber.

A portable DC air-conditioner has a cooler circulation system inside a housing, including a DC compressor, a condenser, an expansion valve and an evaporator. The evaporator is disposed inside an air duct which has an end thereof connected to a fan and another end thereof forming a discharging exit. The condenser is arranged below the evaporator and the air duct has a guiding tube at the bottom thereof so that the water drops made by the evaporator would be guided to flow into the condenser. A distributing portion is disposed on the housing, including a base connected to the discharging exit and at least one hollow frame having a circular slit on the inner edge for cooled air to be discharged. The evaporator in the air duct would produce cooled air and transport the cooled air to the discharging exit to flow out from the circular slit, forming a cooler circulation system with small volume and great efficiency.

An air-conditioning apparatus includes an indoor unit including a pair of lateral air-directing vanes each configured to adjust an orientation of an air flow blown from an air outlet in a lateral direction, and a remote control device configured to receive selection of at least two of a plurality of air flow directions in the lateral direction. The indoor unit includes an indoor-unit controller configured to individually adjust operations of the pair of lateral air-directing vanes in accordance with the selection of the plurality of air flow directions in the remote control device such that a left partial air flow does not collide with a right partial air flow.

An air cleaner is provided. The air cleaner may include a first air cleaning module including a first fan, a first filter, and a first inlet through which air is suctioned in a radial into the first filter; a second air cleaning module provided over the first air cleaner including a second fan, a second filter, and a second inlet through which air is suctioned in the radial direction to the second filter; and an air flow controller coupled with the second air cleaning module and including a third fan to control a flow of the air discharged from the second air cleaning module.

A dehumidifier is provided that may include a main body, a compressor provided within the main body to compress a refrigerant, a plurality of heat exchangers provided within the main body to condense the refrigerant compressed in the compressor or to evaporate the refrigerant, a first fan to discharge air, having undergone heat exchange with the refrigerant evaporated in the plurality of heat exchangers and having subsequently undergone heat exchange with the refrigerant condensed in the plurality of heat exchangers, out of the main body, a mode switch to perform switching between operating modes, including a cooling mode and a dehumidification mode, and a second fan to discharge air, having undergone heat exchange with the refrigerant evaporated in the plurality of heat exchangers in the cooling mode, out of the main body.
