In an inverter air conditioner that performs a cooling function by forming a refrigerant cycle in the order of a compressor, an outdoor heat exchanger, a capillary tube, an indoor heat exchanger, a receiver, and a compressor, a temperature sensor and a pressure sensor are configured to sense the temperature and pressure at the inlet and outlet of the compressor. On / off valves are disposed between the evaporator and the capillary to control the amount of refrigerant circulated along the refrigerant cycle, respectively. Residual refrigerant remaining except for reverse reverse operation and optimum circulating refrigerant To temporarily store the gas, an on / off valve that controls the flow of refrigerant discharged from the receiver, and a capillary tube that compresses the refrigerant passing through the on / off valve to low temperature and low pressure and discharges it to an indoor heat exchanger. It is characterized in that it is sequentially disposed between the heat exchanger to form another refrigerant cycle.
