Energy-saving fan unit for air conditioner ventilation system

Abstract

The invention relates to an energy-saving fan unit for an air conditioning ventilation system. The energy-saving fan unit comprises an air conditioner fan, a ventilation pipeline, an air volume adjusting valve and a sealing mechanism, the air conditioner fan comprises an air inlet, a driving motor, fan blades and an air outlet, the ventilation pipeline comprises a plurality of pipe sections which are sequentially communicated, and one pipe section is connected with the air outlet; the air volume adjusting valve is located between the two pipe sections, one pipe section, the air volume adjusting valve and the other pipe section are sequentially communicated, the air volume adjusting valve comprises a valve body, a valve clack and a valve driving mechanism, a first mounting hole is formed in the inner wall of the valve body, the valve clack is provided with a first blade shaft, and the first blade shaft is in pivot joint with the first mounting hole; the sealing mechanism is arranged on the valve body and installed at the annular gap in the connecting position of the first blade shaft and the valve body so as to block the annular gap, and therefore gas leakage between the valve clack and the outer frame is reduced, the air pressure of the ventilation pipeline is maintained, the air volume is stabilized, and draught fan energy is saved.
