摘要： An air-conditioning system (1) includes: an air conditioner (10) including an outdoor unit (20) and a plurality of indoor units (30) each provided in a corresponding one of a plurality of indoor spaces (A) and each including a first control unit (33); and a second control unit (27) capable of communicating with the first control units (33). Each first control unit (33) is capable of communicating with a countermeasure device (60, 65) if the countermeasure device (60, 65) is installed in correspondence with one of the indoor spaces (A) where the first control unit (33) is located. The second control unit (27) has a first function of prohibiting operation of the air conditioner (10) if a first condition where communication between the first control unit (33) and the countermeasure device (60, 65) is not established in any of the indoor units (30) is satisfied.

摘要： An air conditioning system (10) includes an outdoor unit (12) including a control device (12A), an indoor unit (13) communicably connected to the control device (12A), and an outside air processor (21) communicably connected to the control device (12A). The indoor unit (13) is capable of performing ordinary operation control to adjust a temperature of air in a room, the air being taken in the indoor unit (13), and supply the air into the room, and output restriction control under which an output is restricted as compared with an output under the ordinary operation control. The outside air processor (21) is capable of performing ordinary operation control to adjust at least one of a temperature and a humidity of air outside the room, the air being taken in the outside air processor (21), and supply the air into the room, and output restriction control under which an output is restricted as compared with an output under the ordinary operation control. The control device (12A) causes the outside air processor (21) to shift from the ordinary operation control to the output restriction control on condition that the indoor unit (13) shifts from the ordinary operation control to the output restriction control.

摘要： In a refrigeration apparatus including a refrigerant circuit in which a refrigerant in a gas-liquid two-phase state flows through a liquid-side connection pipe, a refrigerant-amount determining method and a refrigerant-amount determining device capable of grasping an appropriate refrigerant charging amount corresponding to the length of the connection pipe is provided. Provided is a refrigerant-amount determining method for a refrigerant to be charged to a refrigeration apparatus (1) including a refrigerant circuit (10) in which a compressor (21), an outdoor heat exchanger (22) that functions as a condenser, an outdoor expansion valve (28), indoor heat exchangers (41a, 41b) that function as evaporators, a liquid-side connection pipe (5) that feeds the refrigerant, which has passed through the outdoor heat exchanger (22) and then has been decompressed by the outdoor expansion valve (28), to each of the indoor heat exchangers (41a, 41b), and a gas-side connection pipe (6) that feeds the refrigerant, which has passed through each of the indoor heat exchangers (41a, 41b), to a suction side of the compressor (21), are connected to one another. The method determines a refrigerant amount of the refrigerant to be charged to the refrigerant circuit (10) such that a refrigerant amount per unit length of the liquid-side connection pipe (5) increases as a length of the liquid-side connection pipe (5) is larger.
