Abstract: An air-conditioning system includes a humidifier, a dehumidifier, transfer fans for transferring air of an air-conditioned room to a room, a damper for independently controlling an air volume transferred to the room, a system controller for controlling the humidifier, the dehumidifier and the damper, a room humidity sensor and an air-conditioned room humidity sensor. The system controller further includes an air-conditioned room humidity controller for maintaining the humidity of the air-conditioned room within a specified humidity range defined by a minimum humidity and a maximum humidity, an air volume determiner for determining an air volume passing through the damper according to the humidity of the room obtained by the room humidity sensor and the humidity of the air-conditioned room obtained by the air-conditioned room humidity sensor and a damper controller for controlling the air volume transferred to the room passing through the damper.

Abstract: The extruder includes: a cylinder having a first end portion and a second end portion respectively formed at two ends of the cylinder in an axial direction, and an ejection port formed in the first end portion; a screw including a shaft that is configured to rotate within the cylinder, and a screw blade that is provided on an outer circumferential surface of the shaft; a supplier that is attached to the second end portion side of the cylinder and is configured to supply a kneading target to an inside of the cylinder; and a plurality of protruding members that protrude from an inner wall surface of the cylinder.

Abstract: A method for producing a rubber member according to the present invention includes the steps of: supplying a rubber composition to a cylinder provided in an extruder; extruding the rubber composition to a downstream side of the cylinder while kneading the rubber composition in an internal space of the cylinder that includes a plurality of protruding members protruding from an inner wall surface of the cylinder; compressing the rubber composition at least once in the step of extruding the rubber composition to the downstream side; discharging a gas generated from the compressed rubber composition to outside of the cylinder; discharging, through a discharge outlet of the cylinder, the rubber composition after the gas has been generated; and molding the rubber composition that has been discharged through the discharge outlet into a predetermined rubber member shape.
