Abstract
PURPOSE:To prevent breakage of a damper motor and to ensure a motion of switching a damper at a processing air flow, by a method wherein, when a power source is fed to a damper motor, a voltage, simultaneously, is also applied on the motion coil of a relay, connected in parallel to the power source to run the damper motor, and the NC contact of a relay connected in series to the power source of the motor is released. CONSTITUTION:Through rotation of a damper motor 16 under a state to run a motor 11, a damper 15 is moved from a position, where a suction port 5 on the indoor side and a delivery port 6 on the outdoor side intercommunicated with a heat exchange element 8, to a position where a suction port 5 on the indoor side and the delivery port 6 on the outdoor side communicates with an exhaust passage 12. Or, when the damper is moved in a reverse direction to the above, when the power source is fed to the damper motor 16, a voltage, simultaneously, is also applied on a motion coil 18 of a relay 17 connected in parallel to the power source to operate the motion coil. An NC contact 19 of the relay 17 connected in series to the power source of the motor 11 is released to stop the motor 11. Thus, the wind pressure of a blade 10 for exhaust is not exerted on the damper 15, and the bearing of the motor 16 and a built-in gear for reduction are prevented from being damaged.
