A packaged terminal air conditioner unit (PTAC) includes a bulkhead that defines an indoor portion and an outdoor portion. An outdoor fan is positioned within the outdoor portion and a controller is communicatively coupled with the outdoor fan for receiving a command to generate white noise and operating the outdoor fan to create the white noise at a desired decibel level to block out ambient sounds. A user may regulate the outdoor fan speed when the PTAC is not heating or cooling by setting a desired decibel level, e.g., using a control panel of the PTAC.

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 unit comprising a bracket configured to be coupled to a sill of an opening between a first and second environment, the bracket comprising a pivot arm configured to be disposed and extending within the first environment. The bracket is configured to have a first unit positioned on top of the bracket; have the first unit moved on top of the bracket onto the pivot arm; and have the pivot arm and first unit rotated downward so that the first unit is disposed in the first environment and extending downward below the sill of the opening to cause one or more pivot arm guide slots of the pivot arm to rotate from a first configuration to a second configuration.

A method of installing an air conditioning unit in an opening. The method includes securing a bracket to a sill of the opening between a first and second environment where the bracket has a pivot arm disposed and extending within the first environment. The method also includes positioning a first unit of the air conditioning unit on top of the bracket; moving the first unit on top of the bracket onto the pivot arm; and rotating the pivot arm and first unit downward so that the first unit is disposed in the first environment and extending downward below the sill of the opening.

The apparatus and method disclosed herein is a new system that can be used as windows air conditioner's accessary and its possible embodiments.

By first attaching base modules to the window air conditioner's housing and/or window frames, it can create an foundation with opening for attaching other functional modules. The functional modules attached on later are interchangeable and allow a variety of applications and combination of applications.

The invention also makes installing and remove window AC unit more safer and easier.

The invention had built a new ecosystem around the window air conditioner unit. It turns the current wasted spaces around windows AC housing into a unique area where users can design and customize for different functional uses. Because the functional modules are interchangeable, user can switch easily between different modules and designs with different possible combination from time to time to achieve different goals and meet different needs.
