Abstract
A separate air conditioner includes a heat exchanger, an upper fan, a lower fan, the first air flow control for controlling the upper and lower fans in an initial heating period such that the ratio of an upper air flow from the upper fan to a total air flow from both the upper and lower fans decreases as the total air flow increases; and the second air flow control for controlling the upper and lower fans in a stable heating state such that the ratio increases as the total air flow increases. The first air flow control controls the upper and lower fans in a cooling operation such that the upper air flow is inversely proportional to the total air flow, while the second air flow control controls the upper and lower fans in a heating operation such that the upper air flow is proportional to the total air flow.
