摘要： PURPOSE:To use one damper for air conditioning control and disaster prevention and obtain a disaster preventing damper meeting regulations by providing a disaster preventing circuit operating an operation motor from an air conditioning board with a separate power source and a separate wiring as a circuit prior to an air conditioning control circuit. CONSTITUTION:The mechanism of a damper 32 has nearly a known constitution, and it is provided with a casing 40 of the same size as a duct to insert, flanges 42, 44 mounted on the duct, a blade 46 opening and closing in the casing, and a motor device 48 operating the blade 46. A temperature fuse 50 is protruded into the duct, and the blade 46 is closed at the time of a determined temperature. In the case of a fire, relay coils R1, R2 are operated by a disaster preventing closing command 72 from a disaster preventing control board 60, relay contact points 11-R14, R21, R22 are reversed from the position shown and connected to a disaster preventing power source 62, and an air conditioning circuit 70 is interrupted from a motor M. The damper blade 46 is closed by the operation of the motor M. This state is continued until the disaster preventing control board 60 again operates the motor M by a disaster preventing opening command 74 to return the glade 46 to the open position.

摘要： PURPOSE:To perform constant air capacity control over a wide range and to measure the current capacity of air passing through an air duct by making a force which balances with a blade closing force with necessary air capacity operated on blades, and holding the blade and maintaining specific air capacity. CONSTITUTION:An air capacity controller 15 is fitted to a damper. The device 15 is provided with a housing which is fitted to an outer shell, a torsion coil spring 17 which is fixed at one end on a shaft 10, a blade opening extent adjusting lever 18 which is fixed on the shaft 10, and an air capacity control lever 19 which is fitted to the other end of the coil spring 17 and rotatable around the fitting shaft 10. Further, a stud fixed to the lever 18 is projected from a slot formed in the housing and the opening extent of the blade is fixed as usual with a setscrew upon occasion. Then, the stud fixed to the tip part of the lever 19 is projected from the slot formed in the housing 15 and fixed with a thumbscrew at a necessary position of the slot and controlled to necessary constant air capacity. Consequently, the constant air capacity control is performed over a wide range and the current capacity of air flowing through the duct can be measured.
