Abstract
The utility model relates to a single air flue variable wind rate terminal control device, comprising a box body with a ventilating flue inside, an air inlet opening arranged on end of the box body, and an air outlet opening arranged on the other end of the box body. A wing type flux sensor and an air inlet controlling valve are arranged in the air inlet opening, and a regulating device is arranged on the air inlet controlling valve. An air outlet controlling valve is arranged in the air outlet opening, and a regulating device is arranged on the air outlet controlling valve. The flux signal is transferred to the controlling box by the wing type flux sensor. The air inlet controlling valve is regulated by the controlling box to maintain the stabilization of the temperature in a room. When the charge of an air condition changes, the controlled value of the air amount is reset according to the signal of a thermostat in the room. The wing type flux sensor overcomes the disturbance to the main airflow, and increases the measuring precision of the flux sensor. On the condition of lower air speed, the measuring value obtained is still very accurate, and the effect of energy saving is achieved.
