A building system for a building including one or more storage devices storing instructions thereon that, when executed by one or more processors, cause the one or more processors to operate one or more pieces of building equipment associated with a building space based on a first operating mode. The instructions cause the one or more processors to receive an indication to update operation of the building space based on an emergency situation and responsive to receiving the indication to update operation of the building space based on the emergency situation, operate the one or more pieces of building equipment based on a second operating mode, wherein the second operating mode defines one or more second parameters for the one or more pieces of building equipment and is adapted to reconfigure the operation of the building space to address or mitigate the emergency situation.

Disclosed are an air outlet structure, an air outlet method for an air conditioner, and the air conditioner. The air outlet structure may include: a main air outlet channel, a main air outlet, an auxiliary air outlet and an adjusting device; the main air outlet and the auxiliary air outlet are communicated with the main air outlet channel; the adjusting device is provided between the main air outlet channel and the auxiliary air outlet as to make the main air outlet channel send out air through the main air outlet and/or the auxiliary air outlet. With the above structure, the air conditioner may have a broad air supplying scope and a uniform air speed and supply the air to an entire plane, and comfort of the air conditioner may be improved. Thus, the problem that an existing air conditioner has non-uniform air outlet effect may be effectively solved.

A door assembly for an air conditioner indoor unit includes a door mounting plate, including a receiving chamber having a fitting opening on one side and a bottom wall on another side, a door arranged adjacent to the bottom wall of the receiving chamber and configured to be movable toward and away from the door mounting plate, and a plurality of driving assemblies arranged in the receiving chamber. An end of each driving assembly passes through the bottom wall of the receiving chamber to be connected to the door. Locations of the ends of the plurality of driving assemblies connected to the door are uniformly distributed on the door. The plurality of driving assemblies are configured to drive the door to move.

A door unit for an air conditioning system includes a stationary inner screen part, an outer casing part rotatable between different operational positions in relation to the inner screen part, and a flap member attached to the outer casing part. The outer casing part includes first and second inlet openings. The door unit directs a first flow of air in a first air flow channel and a second flow of air in a second air flow channel to a third air flow channel or to the third air flow channel and a fourth air flow channel. The flap member blocks the first air flow channel or the second air flow channel, wherein an internal volume of the door unit enclosed by the inner screen part and the outer casing part forms the fourth air flow channel.
