Abstract: A ventilation system includes a first ventilation device, a second ventilation device, a sensor, and an electronic controller. The first ventilation device includes a first fan. The second ventilation device includes a second fan. The sensor is attached to the first ventilation device. The sensor is configured to detect a state of air and to transmit a detection signal indicative of the detected state of air. The electronic controller is configured to receive the detection signal of the sensor and to control the first ventilation device and the second ventilation device based on the detection signal.

Abstract: A ventilation system includes a plurality of ventilation devices, a sensor, a setting unit, and a transmitter-receiver. The sensor is attached to a predetermined ventilation device of the plurality of ventilation devices. The sensor detects a state of air. The setting unit sets, from the plurality of ventilation devices, a first ventilation device to which the sensor is to be attached, and a second ventilation device with which a detection signal of the sensor is to be shared. The transmitter-receiver receives the detection signal of the sensor and transmits the detection signal to control devices of the first and second ventilation devices. The first and second ventilation devices are set in the setting unit. Each of the control devices of the first and second ventilation devices controls an associated one of the ventilation devices based on the detection signal transmitted from the transmitter-receiver.

Abstract: A ventilation device performs ventilation by supplying outdoor air indoors as supply air and exhausting room air outdoors as exhaust air. The ventilation device includes a heat exchange unit provided with a heat exchange element that performs heat exchange between the supply air and the exhaust air and a humidification unit provided with a humidification element that humidifies the supply air. The heat exchange unit is provided with a supply air blower with which the outdoor air is suctioned and sent to the humidification unit and a supply air delivery port with which supply air sent from the supply air blower is delivered and guided to the humidification unit. The humidification unit is provided with a supply air introduction port that introduces supply air delivered from the heat exchange unit, and a supply air duct that regulates spreading of supply air introduced from the supply air introduction port.

Abstract: A shut-off valve mounting structure is for holding shut-off valves in place in an outdoor unit of an air conditioner, and includes bases, and a fixing portion. The shut-off valves are connected to an indoor unit of the air conditioner via refrigerant communication pipes. The bases extend upwards from a bottom frame of the outdoor unit (2). The fixing portion is continuous with the bases, and holds the shut-off valves in place such that a space exists below the shut-off valves.
