<p><P>PROBLEM TO BE SOLVED: To provide an air conditioner capable of reducing a power distribution time to a switch valve for a gas-liquid separator to save electric power and to secure reliability of a compressor by suppressing the use of the switch valve for the gas-liquid separator in a case when a specific capacity is secured without using the gas-liquid separator in a cooling operation. <P>SOLUTION: The gas-liquid separator 8 disposed in a refrigerant pipe P connecting an electric expansion valve 5 and an indoor heat exchanger 6 is received in an outdoor unit 1A, a gas-phase refrigerant after the gas-liquid separation is returned to the compressor 2 from a bypass circuit 10, the switch valve 11 for the gas-liquid separator controlled by a control section S is disposed in the bypass circuit, and the control section controls the switch valve for the gas-liquid separator to be opened only when all of conditions that an operation command from the inside of a room is the cooling operation, an operational frequency of the compressor is an optional set value or more, an indoor temperature is an optional set temperature or more, and a rotational frequency of an indoor fan motor is an optional set rotational frequency or more, and controls the switch valve for the gas-liquid separator to be closed when even one condition is not satisfied. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
