更部５dとを有している。FIG. 1 is a schematic configuration diagram of a multi-type air conditioner according to an embodiment of the present invention, wherein 1 is an outdoor unit having a compressor 10, and 2 to 4 are indoor units connected to the outdoor unit, respectively. Reference numeral 5 denotes a control device for controlling the outdoor unit 1 and the indoor units 2 to 4. The control device 5 sets a priority room selection unit 5a as an indoor unit selection unit that selects any one of the indoor units 2 to 4 as a priority room, and sets the indoor unit selected by the priority room selection unit 5a. The operation mode setting unit 5b that sets the same operation mode as the selected operation mode to the other indoor units, and increases the blowout air volume of the indoor unit selected as the priority room and the operation frequency of the compressor 10 of the outdoor unit 1. When increasing the air flow rate of the air conditioner control section 5c and the blowout air volume of the indoor unit preferentially selected by the air conditioner capacity control section 5c and the operating frequency of the compressor 10 of the outdoor unit 1, the other indoor units are easily thermo-off.

When performing the cooling operation or the heating operation, one of the indoor units 2 to 4 is selected by the priority room selection unit 5a of the control device 5.
One is selected as the priority room. Then, when the indoor unit selected as the priority room is in the cooling operation mode, the operation mode of the indoor unit in the other room is set to the cooling operation mode by the operation mode setting unit 5b even if the previous operation state is the heating operation mode. Is set. As described above, since the operation mode set for one indoor unit selected as the priority room is unified with the operation mode of the indoor unit for another room, a different operation mode is not set for each indoor unit. By changing the operation mode of the indoor unit selected as the priority room, the operation modes of all the indoor units can be changed at the same time.

ップが十分でない。Further, the multi-type air conditioner has a powerful operation function of temporarily increasing the air-conditioning capacity by increasing the blowing air volume of the indoor unit and the operating frequency of the compressor of the outdoor unit for a predetermined time. In this powerful operation, when the priority room is not selected, when a request for the powerful operation is made in any one of the indoor units 2 to 4, the air conditioning capability control unit 5c of the control device 5 causes the powerful operation to be performed. The blower air volume of the indoor unit that has been requested to be operated is increased, and the operating frequency of the compressor 10 of the outdoor unit 1 is increased. In this case, since the operating conditions of the indoor units in other rooms do not change, the air conditioning capacity of the other indoor units also increases, and the blowout temperature of the indoor units in the room where the powerful operation was requested does not change much, and the air conditioning capacity increases. Is not enough.

せるのである。Therefore, in the above-mentioned multi-type air conditioner, in order to increase only the air conditioning capacity of the indoor unit selected as the priority room, the priority unit selection unit 5a of the control unit 5 controls the indoor units 2 to 5.
One of the four rooms is selected as a priority room. Then, when the powerful operation is requested by the indoor unit selected as the priority room, the air conditioning capability control unit 5 of the control device 5 receives the instruction to increase the air conditioning capability of the indoor unit selected as the priority room.
c, the blowing air volume of the indoor unit for which a powerful operation was requested is increased, the operating frequency of the compressor 10 of the outdoor unit 1 is increased, and the set temperature changing unit 5d of the control device 5 is used to turn off the thermo-off of the other indoor units. Change the set temperature. That is, in the cooling operation, the set temperature of the thermo-off is increased, and in the heating operation, the set temperature of the thermo-off is lowered, and the thermo-off is performed earlier than usual. Focus on the machine.
