AIR CONDITIONING MENU Cargo System Pres. 1/17 AIR CONDITIONING Cargo System Pres. 2/17 The conditioning of the air in the two cargo compartments is fully automatic. The operation for both compartments is similar so we will only look at the forward cargo compartment initially. Ambient air from the cabin area enters the cargo compartment via an inlet isolation valve. Inlet Isolation Valve Inlet Isolation Valve FWD Cabin Ambient Air MENU AIR CONDITIONING Cargo System Pres. 3/17 FWD The air is removed from the compartment either by an extractor fan, or by differential pressure. The air is discharged overboard via an outlet isolation valve. EExxtrtraacctotorrfafann Outlet Isolation Valve Outlet Isolation Valve Overboard Cabin Ambient Air MENU AIR CONDITIONING Cargo System Pres. 4/17 FWD The operation of the two isolation valves and the extraction fan is controlled automatically by a cargo ventilation controller. Cargo Ventilation Controller Overboard Cabin Ambient Air MENU AIR CONDITIONING Cargo System Pres. 5/17 FWD To provide heating of the cargo compartment, hot bleed air is supplied via a trim air valve. The operation of the cargo trim air system is very similar to the trim air system for the air conditioning system. Overboard Cabin Ambient Air HOT BLEED AIR Trim Air Valve Trim Air Valve MENU AIR CONDITIONING Cargo System Pres. 6/17 FWD Each cargo compartment has a Cargo Heating Controller which controls the trim air valve position to regulate the temperature of the compartment. Let’s look at the ECAM COND page to see how information on the Cargo conditioning system is presented to the pilots. Overboard Cabin Ambient Air HOT BLEED AIR Cargo Heating Controller MENU AIR CONDITIONING Cargo System Pres. 7/17 The Cargo heating system is an extension of the Air conditioning system. Hot air is routed from the trim air system, for the Forward cargo hold, and via an independent Hot Air valve for the Aft cargo hold. MENU AIR CONDITIONING MENU Cargo System Pres. 8/17 AIR CONDITIONING MENU Cargo System Pres. 9/17 AIR CONDITIONING MENU Cargo System Pres. 10/17 AIR CONDITIONING MENU Cargo System Pres. 11/17 AIR CONDITIONING Cargo System Pres. 12/17 On the ECAM COND page the indications associated with the cargo compartments are; • the isolation valves • the trim air valves • duct inlet temperature • compartment temperature • aft cargo hot air valve Notice that there are no indications for the extractor fans. MENU AIR CONDITIONING Cargo System Pres. 13/17 On the Overhead Panel there is a CARGO HEAT panel that contains the controls associated with cargo heating and conditioning. MENU AIR CONDITIONING Cargo System Pres. 14/17 For each cargo compartment there is an ISOLATION VALVE pb sw. These pb sws normally remain in their “lights out” auto position. When in this position the cargo ventilation controller will automatically open and close the isolation valves. Aft Cargo Ventilation Controller Forward Cargo Ventilation Controller MENU AIR CONDITIONING Cargo System Pres. 15/17 The temperature selectors send demand signals to the associated cargo heat controllers. The cargo heat controllers then move the trim air valves to adjust the temperature of the air entering the compartment. Aft Cargo Heating Controller Forward Cargo Heating Controller MENU AIR CONDITIONING Cargo System Pres. 16/17 The HOT AIR pb sw controls the aft cargo compartment hot air valve via the aft cargo heating controller. This pb sw normally remain in the “lights out” auto position. Notice that the forward cargo compartment does not have an independent hot air valve. The forward cargo trim air system is fed from the cabin hot air valve. Aft Cargo Heating Controller MENU AIR CONDITIONING Cargo System Pres. 17/17 For normal operation of the cargo conditioning system the only pilot inputs required are: • to confirm that the pb sws are in their normal “lights out” position • to set the required temperatures. Note that the mid position of the temperature selector is approximately 16 degrees C (60 degrees F). The abnormal operation of the system is very similar to those already seen in the Air Conditioning abnormal modules.
