Air conditioner and control circuit

摘要

This air conditioner (12) is provided with a main body unit (25) and an auxiliary casing (26). The main body unit (25) forms a first blow-out opening (31) that blows out an airflow of cold air or warm air. The auxiliary casing (26) forms a second blow-out opening (56) that is attached to at least one side of the first blow-out opening (31) in a movable manner, and that blows out indoor air that has been taken in. A control circuit causes the indoor air to be blown out from the second blow-out opening (56) at a greater wind speed than that of the cold air or warm air blown out from the first blow-out opening (31).
