Abstract: An air conditioner includes an outdoor unit, a plurality of mode change devices including at least one mode changer including a branch duct and a changing valve, and configured to receive a control signal from the outdoor unit to control an operation of the at least one mode changer. A plurality of indoor units are connected to the outdoor unit or the plurality of mode change devices. The outdoor unit may determine an operation mode to operate the plurality of mode change devices a plurality of times. Each of the plurality of indoor units may detect a temperature change of an indoor heat exchanger in response to the operation of the mode change devices, to determine the number of connected mode changers and a connectable mode changer candidate group based on the temperature change of the indoor heat exchanger.

Abstract: An air conditioner and a method for controlling the same are disclosed. The air conditioner is able to operate in an efficient cooling cycle while simultaneously guaranteeing superior cooling performance in a low-temperature operation region. In the air conditioner, an airflow directing apparatus, which is installed in an outdoor unit, suppresses not only natural convection of the air, but also heat exchange between the condenser and outdoor air by the blowing fan, such that the air conditioner forms a normal cooling cycle by guaranteeing condenser pressure. The air conditioner guarantees cooling performance of a low-temperature operation region by adjusting the amount of outdoor air flowing through blade control of the airflow directing apparatus, and operates in an efficient cooling cycle, resulting in acquisition of compressor reliability.
