Airbus A32F Avionic equipment ventilation system

Once again we will take look on ATA 21. The skin air-outlet valve 22HQ is installed in the fuselage skin on the forward-lower right side. This valve is an electrically-operated single-flap valve that includes a second smaller flap. When the aircraft is on the ground, the valve is fully open. In flight, the valve is fully closed. The smaller flap opens during the flight: - When the skin temperature is more than 34 deg.C (93.20 deg.F) (partially open circuit) - If there is smoke in the avionics ventilation system - If the Avionics Equipment Ventilation Computer (AEVC) 10HQ does not operate correctly - If the skin temperature sensor is incorrectly calibrated or does not operate. On the ground, if the valve does not close after the take-off sequence signal, the ground crew can manually close it. Before the manual closing of the valve, the crew must operare toggle switch of the valve to isolate it electrically. The air conditioning system keeps the air in the pressurized fuselage compartments at the correct pressure, temperature and freshness.
