An air conditioner, including an outdoor unit and a control system, an air outlet being provided at the top of a box body of the outdoor unit. The air conditioner further includes a snow hood in communication with the air outlet, a rotation driving device connected to the snow hood, and a wind direction detection device provided on the box body. The snow hood is rotatably provided on the top of the box body, and the rotation driving device and the wind direction detection device both communicate with the control system.

A heat exchanger includes: a surface with a water-repellent coating. The surface has a surface structure that includes protrusions. Condensed water droplets, each having a droplet diameter that allows a subcooled state to be maintained even under a predetermined freezing condition, combine with one other on the surface and generate an energy. The surface structure uses the energy to remove the combined condensed water droplets from the surface.

The present disclosure provides an air conditioner outdoor unit that includes: a motor having first and second output shafts; a first-stage fan blade connected to the first output shaft; a second-stage fan blade connected to the second output shaft. The motor is configured to drive the first-stage and second-stage fan blades to rotate, and rotation directions of the first-stage and second-stage fan blades are opposite. The motor is located between the first-stage and second-stage fan blades, or on the same side of the first-stage and second-stage fan blades. The outdoor unit is provided with a motor, and first-stage and second-stage fan blades, so that the motor drives the first-stage fan blade to rotate through the first output shaft, and drives the second-stage fan blade to rotate in the opposite direction through the second output shaft. By recovering the rotational energy of the airflow, higher wind pressure is achieved.

Disclosed herein is an air conditioner. The air conditioner includes a housing having an inlet and an outlet, and having a first guide surface forming the outlet and a second guide surface facing the first guide surface provided therein, a heat exchanger configured to heat-exchange air suctioned through the inlet, a blower fan configured to suction air from the inlet, heat-exchange the air by passing air through the heat exchanger, and discharge air toward the outlet, and an airflow control unit provided to be movable between a first position adjacent to one end portion of the outlet from which air is discharged and a second position spaced apart from the end portion of the outlet from which air is discharged, and protruding from the first guide surface or the second guide surface when the airflow control unit placed at the first position.

Embodiments of the present disclosure are therefore directed toward a condenser section that is configured to draw an air flow into the condenser section, a control section configured to enclose electrical components, and a partition extending between the condenser section and the control section. The partition may include a first air passage and a second air passage formed therein, where the first air passage is configured to enable a portion of the air flow to flow from the condenser section into the control section to cool the electrical components and the second air passage enables the portion of air flow to from the control section to the condenser section.

A hood assembly for a heating, ventilation, and air conditioning (HVAC) unit includes a top panel comprising a first panel portion and a second panel portion adjustably coupled to one another, wherein the top panel is configured to rotatably couple to a housing of the HVAC unit. The hood assembly further includes a filter frame rotatably coupled to the top panel, wherein the filter frame is configured to support at least one filter. The hood assembly is adjustable between a collapsed configuration and a deployed configuration, the first panel portion and the second panel portion are configured to translate relative to one another during transition of the hood assembly between the collapsed configuration and the deployed configuration, and the top panel is configured to contain the filter frame within the housing in the collapsed configuration.
