A mobile climate control assembly that includes a portable housing with a first fan blower-wheel assembly and a second fan blower assembly each respectively having a wheel blade member, partially surrounded by an air deflector wall, disposed within a housing cavity and operably configured to rotate 360° around an axis of rotation parallel and non-co-planar with respect to one another. The assembly also includes a fan motor operably coupled to the wheel blade members and an electronic controller electronically and communicatively coupled to the fan motor and operably configured to independently and selectively control rotation of the wheel member of each of the first and second fan blower-wheel assemblies to generate an ambient air velocity gradient along at least an approximate 90° angular traverse path from the front face and without rotation of the portable housing.

A window fan is provided that includes a fan housing and chamber assembly. The fan housing includes a front panel with an air outlet and a rear panel with an air inlet and defines a central chamber. The chamber assembly is positioned within the central chamber of the fan housing and includes a cylindrical fan rotatably mounted within the chamber and driven by a fan motor. An air duct assembly is rotatably mounted within the chamber having an air duct panel that is moveable from an open to closed position such that the air duct panel, when in the closed position blocks the airflow through the window fan and permits air flow through the window fan when in the open position. The fan of the window fan assembly may be a cross flow blower fan.

A method of a fan system directing an air stream at a target can include receiving, with a controller, a first image from an image capture sensor and analyzing the first image from the image capture sensor to determine a first location of the target. The method can also include receiving a second image from the image capture sensor and analyzing the second image from the image capture sensor to determine a second location of the target. The method can also include comparing the first location of the target and the second location of the target and sending a signal to a first motor to rotate a housing about a first axis respective to a base to direct an air stream exiting an outlet of a channel at the target.

An air blower according to an embodiment of the present invention comprises: a support body through which a suction part is formed; a tower coupling part which is formed above the support body and in which a rotation module is installed; a dual discharge part which is coupled to the rotation module and includes a first discharge tower and a second discharge tower extending upward from the support body to be symmetrical to each other; and a control part which individually controls the rotation of the dual discharge part, wherein the control part can control the rotation angles of the first discharge tower and the second discharge tower so that air discharged from the first discharge tower and air from the second discharge tower is mixed, and the mixed air has an air volume larger than that of the air discharged from any one discharge tower among the first discharge tower and the second discharge tower.

First and second towers may discharge air. An airflow guide or converter may change a direction of the air discharged from the first tower and the second tower by moving a gate inside and outside of at least one of the first or second towers so as to block discharged air flowing forward and selectively facilitate an upward air flow. The airflow converter may include a guide motor to provide a driving force, the gate, which may reciprocate between the inside and the outside of the first and/or second towers; and a board guider connected to the gate to transmit a driving force of the guide motor to the gate as a linear motion force.
