PROBLEM TO BE SOLVED: To solve such problems that re-heating and dehumidifying operation in a heating circuit can not be effected whereby the control range of an indoor temperature or a humidity is limited and a second flow rate control valve is installed in an indoor heat exchanger whereby a refrigerant pressure loss is increased and the deterioration of performance upon normal cooling or heating operation is caused, in a conventional air conditioner, in which a compressor, the indoor heat exchanger, a first flow rate control valve, an outdoor heat exchanger and a four-way valve are provided, and the indoor heat exchanger is divided into a first indoor heat exchanger and a second indoor heat exchanger while a second flow rate control valve is provided between the first and second heat exchangers to realize the re-heating and dehumidifying operation. SOLUTION: The second flow rate control valve is provided and a gas and liquid separating vessel is provided between the first flow rate control valve and the indoor heat exchanger while a gas bypass circuit from the gas and liquid separating vessel is connected to the suction side of the compressor and a third flow rate control valve is provided on the gas bypass circuit. |
