Abstract: PURPOSE: A method for controlling dehumidified operation of inverter heat pump air conditioner is provided to control for using a capillary for heating on dehumidified operation by closing a two-way valve of an expansion device on low-frequency operation area. CONSTITUTION: A method includes the steps of: a dehumidified operation step(S11) lowering operational frequency of a compressor to operate when indoor temperature reaches a fixed temperature; an examining step(S12) examining whether the frequency of the compressor is lower than a fixed frequency(X) during the dehumidified operation; a two-way valve closing step(S13) closing a two-way valve in an expansion device when the operational frequency is lower than the fixed frequency; and a dehumidified operation examining step(S14) periodically examining whether the dehumidified operation is executed to keep the two-way valve closed when the dehumidified operation is being executed and to finish the dehumidified operation when the dehumidified operation is not executed.
