In this segment we will discuss the Ventilation section of the Airbus A320 Overhead. The avionics ventilation system is fully automatic. It cools the electrical and electronic components in the avionics compartment and on the flight deck, including the instrument and circuit breaker panels. It uses two electric fans to force the circulation of cooling air. Whatever the configuration of the avionics ventilation system is, a part of the avionics ventilation air is sucked from the cockpit through the different cockpit panels. FANS Two electric fans continuously circulate air around the avionics equipment, when the aircraft is electrically supplied. The Fan Speed Controller (FSC)  controls the avionics ventilation fan speed as a function of temperature:: 1. High speed when the ventilation air temperature is above +40 °C (104 °F ) 2. Low speed when the ventilation air temperature is below +35 °C ( 95 °F) SKIN AIR INLET AND OUTLET VALVES These valves admit air from outside the aircraft and evacuate hot air from the avionics equipment. SKIN EXCHANGE INLET AND OUTLET BYPASS VALVES These valves enable air to circulate between the avionics bay and the space under the cargo compartment floor. AIR CONDITIONING INLET VALVE This valve opens to enable the air conditioning circuit to supply fresh air to the avionics bay. SKIN EXCHANGE ISOLATION VALVE This valve connects or isolates the skin heat exchanger. AVIONICS EQUIPMENT VENTILATION CONTROLLER (AEVC) The AEVC controls the operation of all fans and valves in the avionics ventilation system.
