摘要： An outdoor unit is configured to include a compressor and a heat source side heat exchanger. Indoor units are configured to include first expansion devices and use side heat exchangers, and air-condition an air-conditioned space. Branching devices, connected by pipes to the outdoor unit by a plurality of main pipes and connected by pipes to each indoor unit by a plurality of branch pipes, are configured to branch a refrigerant from a side of the main pipes and circulate the refrigerant to the branch pipes, and converge the refrigerant from a side of the branch pipes and circulate the refrigerant to the main pipes. A refrigerant concentration detecting device is installed in a non-air-conditioned space. A shutoff valve control device is configured, upon determining that the refrigerant has leaked, to control shutoff devices and to shut off the refrigerant flows.
