摘要： An air conditioning system includes an outdoor unit including a control device, an indoor unit communicably connected to the control device, and an outside air processor communicably connected to the control device. The indoor unit is capable of performing ordinary operation control to adjust a temperature of air in a room, the air being taken in the indoor unit, 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 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, 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 causes the outside air processor to shift from the ordinary operation control to the output restriction control on condition that the indoor unit shifts from the ordinary operation control to the output restriction control.

摘要： An air conditioner has a refrigerant circuit in which a refrigerant circulates and a controller, and is configured to condition air in an indoor space. A countermeasure device is provided against leakage of the refrigerant to the indoor space. A detector is configured to detect a concentration of the refrigerant in the indoor space. A first relay is connected to the controller and the countermeasure device. The controller closes the first relay when the concentration of the refrigerant detected by the detector exceeds a predetermined allowable concentration. The countermeasure device operates when the first relay is closed.

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

摘要： A refrigeration cycle system includes a refrigeration cycle, a communication line, a refrigerant sensor to detect a refrigerant leak, a safety device, and a first electric wire different from the communication line. The refrigeration cycle unit includes utilization-side and heat source-side units connected by refrigerant connection pipe. The sensor is connected to the utilization-side unit. The safety device includes at least one of an alarm that makes a notification of refrigerant leak upon detection by the sensor, a ventilation device that operates upon detection of the leak, and a shutoff valve device that closes a shutoff valve on the pipe upon detection of the leak. The first electric wire is dedicated for interlock and connects between the utilization-side unit and safety device. The heat source-side unit is prohibited from operation when the utilization-side unit is not connected to the safety device via the first electric wire.
