A window air conditioner includes a casing including an indoor portion and an outdoor portion, an indoor fan wheel arranged in the indoor portion, and an indoor heat exchanger arranged in the indoor portion. The indoor portion includes an air inlet and an air outlet. The indoor heat exchanger includes a first heat exchange portion extending vertically and a second heat exchange portion connected to the first heat exchange portion and extending obliquely towards the indoor fan wheel.

Described herein is a heating/cooling window unit designed to be compact and reversible in operation to provide both heated and cooled air to an indoor room. The heating/cooling device is equipped with a touch control panel, a heat pump, and a set of cooling and circulating fans.

An air conditioner includes a suction panel including a suction grille that defines a suction port configured to receive air, an heat exchanger and a fan that are positioned within the case, and an ion generator disposed in the suction panel and configured to generate ions in the air received through the suction port. The suction panel defines an installation groove recessed from an upper surface of the suction panel and configured to receive the ion generator therein. The ion generator is accommodated inside the installation groove and configured to provide ions toward the upper surface of the suction panel in an upward direction that defines a preset angle with respect to the suction panel.

A movable air conditioner includes an air conditioner main body, an air conditioning unit installed in the air conditioner main body and configured to generate a cold air or a warm air, a moving unit configured to move the air conditioner main body, a control unit configured to control the air conditioning unit and the moving unit, and a human body recognition unit configured to recognize a person existing in a specific space. The control unit is configured to control the moving unit so that the air conditioner main body is moved toward the person recognized by the human body recognition unit so as to supply the cold air or the warm air from the air conditioning unit to the person recognized by the human body recognition unit.

A turbo fan includes a hub for coupling a rotating shaft of a motor, a shroud, and a plurality of blades. Each blade includes an inner insertion portion disposed between the hub and the shroud, and an outer extension portion extending from the inner insertion portion and protruding beyond an outer circumference of the hub. Each blade has a positive pressure surface that includes a front surface facing toward a rotational direction and has a convex shape, and a negative pressure surface that includes a rear surface facing toward an opposite direction to the rotational direction and has a concave shape. Each blade further includes a first flow guide protrusion protruding from the positive pressure surface and arranged at an outer end of the outer extension portion, and extends from one side to the other side of the outer end of the outer extension portion in an axial direction.

An air conditioning and heat pump tower includes a main casing, a plurality of connecting pipes, a compressor, a front heat exchanger, a rear heat exchanger, a fan unit, and an energy efficient arrangement. The energy efficient arrangement includes a first pre-heating heat exchanger supported in a front compartment of the main casing, and positioned between an outdoor air intake opening and an outdoor heat exchanging portion of the front heat exchanger. The air conditioning and heat pump tower may be operated between an air conditioning mode for absorbing heat from the indoor space, and a heat pump mode for producing heat to the indoor space. A predetermined amount of ambient air may be drawn through the outdoor air intake opening and may be pre-heated by the energy efficient arrangement before delivering to the indoor space.

Disclosed herein is an air conditioner comprising, a housing in which an outlet is formed, a heat exchanger positioned inside the housing, and a fan positioned behind the heat exchanger. The fan configured to blow air to the heat exchanger. And a filter assembly coupled to the housing. The filter assembly configured to filter air entering the fan. The filter assembly covering a rear portion of the fan.
