摘要： Electricity wasting due to an unnecessary operation is prevented and the usability is improved. A multi air conditioner includes an outdoor unit, a first indoor unit and a second indoor unit. The first indoor unit and the second indoor unit are connected to the outdoor unit and are respectively disposed in different rooms. When the first indoor unit is operated based on a first operating mode, if an operation start instruction based on a second operating mode which is different from the first operating mode is sent to the second indoor unit from a remote controller without using an internet (S5: YES, S7: NO), the first indoor unit becomes an operation stop state and the second indoor unit starts an operation based on the second operating mode on condition that the last instruction to the first indoor unit is sent from a smart phone via the internet (S9: YES) (S12).

摘要： An air conditioner which is able to prevent leaked refrigerant gas from disadvantageously stagnating at a part of a room space when leakage of refrigerant gas occurs in an indoor unit is provided.An air conditioner of the present invention includes an indoor unit having an upper outlet port and a lower outlet port and uses flammable refrigerant, the air conditioner including: a shutter provided at the lower outlet port and is configured to switch between a blowout capable state in which wind is blown out and a blowout incapable state in which no wind is blown out; a refrigerant gas sensor provided in the indoor unit, and a controlling unit configured to control the shutter. In a driving state in which the lower outlet port is in the blowout incapable state, when the refrigerant gas sensor detects the refrigerant gas, the controlling unit switches the lower outlet port from the blowout incapable state to the blowout capable state.
