AIR CONDITIONING MENU Normal Operation 1/69 AIR CONDITIONING Normal Operation 2/69 We will look at using the Air Conditioning system during a normal flight. As part of the aircraft walk around check that the pack inlet and outlet areas are clear of debris, and the RAM Air Valve is closed. MENU AIR CONDITIONING Normal Operation 3/69 Let’s assume that you are about to start the flight. The APU is running and you require Air Conditioning. MENU AIR CONDITIONING Normal Operation 4/69 You are now in the cockpit, and this is how you find the AIR COND panel during your scanning sequence. Notice that, except for the OFF lights on the two PACK pbs, all other pbs are in the normal lights out position. MENU AIR CONDITIONING Normal Operation 5/69 One of the items in the cockpit preflight is to extinguish all white lights on the overhead panel. So that you can watch what is happening let’s have a look at the ECAM BLEED page. Call the ECAM BLEED page MENU AIR CONDITIONING MENU Normal Operation 6/69 One of the items in the cockpit preflight is to extinguish all white lights on the overhead panel. So that you can watch what is happening let’s have a look at the ECAM BLEED page. No, to call the ECAM BLEED page, press the BLEED pb on the ECP. AIR CONDITIONING MENU Normal Operation 7/69 One of the items in the cockpit preflight is to extinguish all white lights on the overhead panel. So that you can watch what is happening let’s have a look at the ECAM BLEED page. No, to call the ECAM BLEED page press the BLEED pb on the ECP. AIR CONDITIONING Normal Operation 8/69 Now extinguish the PACK 1 OFF light. For that, switch PACK 1 to ON. Switch PACK 1 to ON. MENU AIR CONDITIONING MENU Normal Operation 9/69 Now extinguish the PACK 1 OFF light. For that, switch PACK 1 to ON. No, to Switch PACK 1 on press the PACK 1 pb. AIR CONDITIONING MENU Normal Operation 10/69 Now extinguish the PACK 1 OFF light. For that, switch PACK 1 to ON. No, to Switch PACK 1 on press the PACK 1 pb. AIR CONDITIONING MENU Normal Operation 11/69 AIR CONDITIONING Normal Operation 12/69 Notice : • the amber FAULT light on the PACK 1 pbs • the control valve indication switching from green to amber. Both of these amber indications occur because PACK 1 is ON but no bleed air is available to it. Switch PACK 2 on. MENU AIR CONDITIONING MENU Normal Operation 13/69 Notice : • the amber FAULT light on the PACK 1 pb • the control valve indication switching from green to amber. Both of these amber indications occur because PACK 1 is ON but no bleed air is available to it. No, to Switch PACK 2 on press the PACK 2 pb. AIR CONDITIONING MENU Normal Operation 14/69 Notice : • the amber FAULT light on the PACK 1 pb • the control valve indication changes from green to amber. Both of these amber indications occur because PACK 1 is ON but no bleed air is available to it. No, to Switch PACK 2 on press the PACK 2 pb. AIR CONDITIONING MENU Normal Operation 15/69 AIR CONDITIONING Normal Operation 16/69 As for PACK 1, notice : • the amber FAULT light on the PACK 2 pb • the control valve indication changes from green to amber. As before , there is no available bleed air to PACK 2. MENU AIR CONDITIONING Normal Operation 17/69 Since you are expecting a standard passenger load, the pack flow selector can be selected to NORMal. Set PACK FLOW to NORM MENU AIR CONDITIONING MENU Normal Operation 18/69 Since you are expecting a standard passenger load, the pack flow selector can be selected to NORMal. No, to set NORM pack flow use the PACK FLOW selector AIR CONDITIONING MENU Normal Operation 19/69 Since you are expecting a standard passenger load, the pack flow selector can be selected to NORMal. No, to set NORM pack flow use the PACK FLOW selector AIR CONDITIONING Normal Operation 20/69 There are no changes to the ECAM indications. The PACK FLOW selector only affects the pack flow rate once the engines are running and supplying bleed air to the packs. We will look at the use of the PACK FLOW selector later in this module. MENU AIR CONDITIONING Normal Operation 21/69 It is now time to get some air to the packs. As the APU is already running, set the APU BLEED to ON and watch the ECAM indications. Switch APU BLEED to ON. MENU AIR CONDITIONING MENU Normal Operation 22/69 It is now time to get some air to the packs. As the APU is already running, set the APU BLEED to ON and watch the ECAM indications. No, to switch on the APU BLEED use the APU BLEED pb. AIR CONDITIONING MENU Normal Operation 23/69 It is now time to get some air to the packs. As the APU is already running, set the APU BLEED to ON and watch the ECAM indications. No, to switch on the APU BLEED use the APU BLEED pb. AIR CONDITIONING MENU Normal Operation 24/69 AIR CONDITIONING MENU Normal Operation 25/69 AIR CONDITIONING Normal Operation 26/69 Notice: • the APU valve indication has changed to inline green, • the X-BLEED valve has automatically opened. Notice the X-BLEED switch is in the AUTO position, • both feed lines to the packs have been connected. Let’s now look at the packs. MENU AIR CONDITIONING MENU Normal Operation 27/69 AIR CONDITIONING MENU Normal Operation 28/69 AIR CONDITIONING MENU Normal Operation 29/69 AIR CONDITIONING MENU Normal Operation 30/69 AIR CONDITIONING Normal Operation 31/69 Notice; • The FAULT lights are extinguished, due to the air supply, • the pack flow valves are opened, • the pack flows increase, • the bypass valves move, • the supply lines to the mixing unit are now connected. MENU AIR CONDITIONING Normal Operation 32/69 Call the ECAM COND page. Both packs are now providing air conditioning. Let’s look at temperature regulation of the Air Conditioning system. This is better seen on the ECAM COND page. MENU AIR CONDITIONING MENU Normal Operation 33/69 Both packs are now providing air conditioning. Let’s look at temperature regulation of the Air Conditioning system. This is better seen on the ECAM COND page. No, to call the ECAM COND page press the COND pb on the ECP. AIR CONDITIONING MENU Normal Operation 34/69 Both packs are now providing air conditioning. Let’s look at temperature regulation of the Air Conditioning system. This is better seen on the ECAM COND page. No, to call the ECAM COND page press the COND pb on the ECP. AIR CONDITIONING MENU Normal Operation 35/69 AIR CONDITIONING MENU Normal Operation 36/69 AIR CONDITIONING Normal Operation 37/69 Look carefully at the indications, notice in particular: • The zone temperatures, • and the duct inlet temperatures. MENU AIR CONDITIONING Normal Operation 38/69 Temperature regulation is achieved the same way for all zones. We will demonstrate the concept using the cockpit zone as an example. MENU AIR CONDITIONING Normal Operation 39/69 The Cockpit zone temperature selector is in the 12 o’clock position. In this position, a zone temperature of approximately 24 degrees Celsius is demanded. MENU AIR CONDITIONING Normal Operation 40/69 As the 15 degrees Celsius of the cockpit zone is well below the demanded 24 degrees, the zone controller sends a command to increase the amount of hot air added. MENU AIR CONDITIONING MENU Normal Operation 41/69 AIR CONDITIONING MENU Normal Operation 42/69 AIR CONDITIONING Normal Operation 43/69 Due to this command; • the trim air valve opens, • the zone duct temperature increases and so, warm air is supplied to the cockpit zone, • the cockpit zone starts to warm up. MENU AIR CONDITIONING Normal Operation 44/69 Once the Cockpit zone reaches the demanded temperature the trim air valve will move reducing the amount of hot air. And then will move as required to maintain the zone temperature. MENU AIR CONDITIONING Normal Operation 45/69 It is now time to start the engines. So that you can watch what is happening let’s go back to the ECAM BLEED page. Note; Normally the ENGINE page is displayed during engine start. For training purposes we will display the BLEED page. Call the ECAM BLEED page. MENU AIR CONDITIONING MENU Normal Operation 46/69 It is now time to start the engines. So that you can watch what is happening let’s go back to the ECAM BLEED page. No, to call the ECAM BLEED page press the BLEED pb on the ECP. AIR CONDITIONING MENU Normal Operation 47/69 It is now time to start the engines. So that you can watch what is happening let’s go back to the ECAM BLEED page. No, to call the ECAM BLEED page press the BLEED pb on the ECP. AIR CONDITIONING Normal Operation 48/69 Let’s start the engines. Be sure to watch the pack valves on the ECAM BLEED page. Click on either engine. MENU AIR CONDITIONING Normal Operation 49/69 As soon as the Engine Start sequence begins the Pack Valves close. This is so that all of the APU bleed air can be used to start the engines. Let’s complete the sequence. MENU AIR CONDITIONING MENU Normal Operation 50/69 AIR CONDITIONING Normal Operation 51/69 When the engine starting sequence is completed: • the pack valves open • the APU bleed supplies the packs. MENU AIR CONDITIONING Normal Operation 52/69 Notice that the Engine bleed valves are closed, even with both engine running. This is because APU bleed has priority over the Engine bleed. So, if you were departing from a performance limited runway, the packs could run from the APU bleed air, resulting in no loss of engine performance (no weight penalty). MENU AIR CONDITIONING Normal Operation 53/69 However, today, in our example, the APU is no longer required. Switch Off the APU Bleed. MENU AIR CONDITIONING MENU Normal Operation 54/69 However, today, in our example, the APU is no longer required. No, to switch off the APU Bleed use the APU BLEED pb. AIR CONDITIONING MENU Normal Operation 55/69 However, today, in our example, the APU is no longer required. No, to switch off the APU Bleed use the APU BLEED pb. AIR CONDITIONING MENU Normal Operation 56/69 AIR CONDITIONING MENU Normal Operation 57/69 AIR CONDITIONING Normal Operation 58/69 When the APU Bleed switch is selected off; • the APU Bleed and Cross bleed valves close, • the link lines disappear, • and both engine bleed valves open supplying the packs with bleed air. MENU AIR CONDITIONING Normal Operation 59/69 Notice that the Pack flow reduces. This is because the engines provide a higher flow rate than the APU. Also note that the Air Conditioning Control panel is now in a Normal lights out configuration. MENU AIR CONDITIONING Normal Operation 60/69 When the APU is shutdown, the APU symbol on the BLEED Page is removed. MENU AIR CONDITIONING Normal Operation 61/69 During the flight phase the air Conditioning system will work automatically and the only likely pilot input that may be required is to adjust zone temperature. Let us assume that you wish to cool down the cockpit. To demonstrate, please select the cockpit zone selector to cold. MENU AIR CONDITIONING MENU Normal Operation 62/69 During the flight phase the air Conditioning system will work automatically and the only likely pilot input that may be required is to adjust zone temperature. Let us assume that you wish to cool down the cockpit. No. Click on the cockpit zone selector. AIR CONDITIONING MENU Normal Operation 63/69 During the flight phase the air Conditioning system will work automatically and the only likely pilot input that may be required is to adjust zone temperature. Let us assume that you wish to cool down the cockpit. No. Click on the cockpit zone selector. AIR CONDITIONING Normal Operation 64/69 You have now demanded a cockpit zone temperature of 18 degrees. Because a low temperature has been demanded, the trim air valve will close and the cool pack output will feed the cockpit zone. MENU AIR CONDITIONING Normal Operation 65/69 Note that each increment on the zone temperature selector scale is 2 degrees which gives a selectable range from 18 degrees at COLD to 30 degrees at HOT. 180 200 220 260 280 300 240 MENU AIR CONDITIONING Normal Operation 66/69 In situations of low passenger numbers the Pack flow selector can be set to LOW. This has the effect of reducing the bleed demand from the engines and will therefore save fuel. MENU AIR CONDITIONING Normal Operation 67/69 Occasionally with a full passenger load and high ambient temperatures it may be necessary to select High pack flow and COLD to reduce the cabin temperature. Using high pack flow will increase the bleed demand from the engines and use more fuel. Once airborne the Flow selector should be returned to Normal and the temperature selectors adjusted as required. MENU AIR CONDITIONING Normal Operation 68/69 After landing and engine shutdown the system can be set to run from the APU , switched off completely, or MENU AIR CONDITIONING Normal Operation 69/69 an external conditioning unit can be connected via a low pressure connection point on the underside of the aircraft. The low pressure air is fed to the mixing unit and then into the three zones. There are no indications in the cockpit to show that an external conditioning unit is in use.
