AIR CONDITIONER AND CONTROL METHOD THEREOF

摘要

An aspect of the present invention relates to an air conditioner and a method for controlling the same, which restrain a refrigerant stored in a refrigerant storage part from rapidly flowing into a main refrigerant circuit when the type of operation is switched. An air conditioner according to an embodiment of the present invention comprises: a refrigerant circuit including a compressor, a condenser, an expansion valve, and an evaporator; a refrigerant amount detection apparatus for determining whether a refrigerant state at the exit of the condenser is a super-cooled state or a gas-liquid two-phase state, and calculating a refrigerant amount ratio within the refrigerant circuit on the basis of a setting value predetermined according to the refrigerant state and at least one of the temperature and the pressure detected in the refrigerant circuit; and a control unit for controlling the refrigerant circuit according to the refrigerant amount ratio calculated by the refrigerant amount detection apparatus.
