The relay unit and the outdoor unit forms a refrigerant circuit. The outdoor unit includes first and flow switching devices each switching an associated flow passage for the refrigerant between a plurality of flow passages, according to an operation mode. An outflow pipe and an inflow pipe through which refrigerant flows from the outdoor unit to the relay unit and from the relay unit into the outdoor unit, respectively, are between the outdoor unit and the relay unit. The first flow switching device is connected to the compressor, the second flow switching device, and the outflow pipe. The second flow switching device is connected to the first flow switching device and the inflow pipe.

  • Patent number: 5829997
    Abstract: A connecting apparatus which permits the connection of a connector unit (9) to a connector of external equipment (2) by the actuation of an operating lever (11) only when the external equipment (2) is placed in a mounting recess (6), whereas when no external equipment is placed in the recess (6), associated parts for moving the connector unit (9) do not respond to the actuation of the operating lever (11). Hence, movable terminals of the connector unit (9) will not be exposed to the outside even if the operating lever (11) is actuated inadvertently. The connecting apparatus is provided with a sensor mechanism for sensing the presence of the external equipment (2), and a switching mechanism operatively associated with the sensor mechanism to selectively engage the operating lever (11) with a part (12) for moving the connector unit (9) or disengage them from each other.
