Zusammenfassung:PROBLEM TO BE SOLVED: To enable one kind of device to perform an operation suitable for a pressure reducing operation of a mating device even if the mating device shows any type of pressure reducing operation. SOLUTION: In an air conditioner 10 provided with an outdoor device 20 and an indoor device 30 in which a changing-over of cooling operation and heating operation can be carried out, the outdoor device 20 is provided with a manual switch 51a which can change over a pressure reducing operation of an outdoor electric expansion valve EV-1. When the indoor device 30 is not provided with a pressure reducing mechanism, the manual switch 51a is changed over in such a way that the outdoor electric expansion valve EV-1 always performs a pressure reducing operation. When the indoor device 30 performs a pressure reducing operation only in a cooling or heating mode, the manual switch 51a is changed over in such a way that the outdoor electric expansion valve EV-1 may perform a pressure reducing operation only in a mode where the indoor device 30 does not perform the pressure reducing operation.
