 A. AFT Cargo-Compartment Ventilation-System Suction from the extraction fan 35HN causes air to flow into the ventilation system of the AFT cargo compartment when the extraction fan 35HN operates on the ground or in flight. Three inlets installed along the compartment lower left-hand sidewall, direct the air towards the compartment floor area. An isolation valve 34HN is installed in distribution ducts upstream of the compartment inlets. The AFT compartment air is extracted through two outlets near the compartment ceiling on the aft end wall. The air goes through the extraction fan 35HN and an isolation valve 33HN and is discharged in the area of the outflow valve 10HL.
 B. System Performance
 (1) Flowrate
 The flowrate through the AFT cargo compartment is: Volumetric Airflow Mass Flow
 -ground 160 l/s 190 g/s,
 -flight 160 l/s 141 g/s.

 A. Cargo Ventilation Controller (Ref. Fig. 001) The cargo ventilation controller 10HN is of a modular construction and consists of: - a chassis, - a common power supply module, - a FWD cargo ventilation module, - a FWD cargo power relay, - an AFT cargo ventilation module, - an AFT cargo power relay, - a spare module connector, - a spare power relay socket. These modules are enclosed in a metal case. They are installed on the outboard side of relay box 103VU, in the avionics compartment. The cargo ventilation controller 10HN controls and monitors the isolation valves 33HN, 34HN and the extraction fan 35HN. The controller sends a signal to ECAM and CFDS if there is a fault in the isolation valves or extraction fan.
