1. An air circulation apparatus comprising:
at least one flow generator to generate an airflow;
an inlet to pass air from surroundings to the at least one flow generator;
a first air outlet and a second air outlet, each air outlet for exhausting the airflow from the at least one flow generator;
a drive apparatus operable to move the second air outlet;
an air conditioning device operable to air condition the airflow to be exhausted from at least the second air outlet; and
a controller configured to operate an air circulation mode to circulate air by movably positioning the second air outlet below the first air outlet,
operate the at least one flow generator to generate the airflow, and
operating the air conditioning device to air condition the airflow to be exhausted from the second air outlet, wherein an air temperature of the exhausted airflow of the second air outlet is greater than an air temperature of the exhausted airflow of the first air outlet,
wherein the air circulation apparatus comprises:
a body,
a bar, and
the drive apparatus provided between the body and the bar and operable to drive the bar relative the body, and
the first air outlet is disposed at the body and the second air outlet is disposed at the bar,
wherein the first air outlet extends around a periphery of the body, the body comprises one or more dampers, the controller configured to operate the one or more dampers to selectively shut off a lower portion of the first air outlet.
