A. Operation of the Cockpit and Cabin Temperature Control The temperature of the conditioned air, which is supplied to the individual zones, is either determined by the Zone Controller (ZC) or by the maximum capabilities of the system. The system capacity limiting supply air-temperatures are only required for extreme operating conditions e.g. cooling the cabin on a very hot day or heating the cabin in a cold soaked airplane. Between these two extreme operating conditions the conditioned air temperature must be modulated to maintain a stable cabin temperature.
The pilot selects the desired cockpit and cabin temperatures on the temperature selectors within a range from +18 DEG.C (+64.40 DEG.F) up to +30 DEG.C (+86.00 DEG.F). The zone controller determines from the input values of the: - temperature selectors, - cabin sensors, - duct sensors, - mix manifold sensors, an appropriate pack discharge temperature to the zone with the lowest supply air demand. The zone duct air temperature is normally limited from +8 DEG.C (+46.40 DEG.F) to +50 DEG.C (+122.00 DEG.F). During full up/down operations these limits can be overridden when the cabin temperature exceeds the nominal zone temperature (+18 DEG.C up to
R 1EFF : ALL 1 21-60-00Page 18 1 1 Aug 01/05 1 1 1CES 1 +27 DEG.C). In this case the zone inlet duct limitations will extend from +2 DEG.C (+35.60 DEG.F) to +70 DEG.C (+158.00 DEG.F). The pack temperature control will only satisfy the zone with demand for the coldest air. The other two zones will receive additional heating from the trim air system so that the mix of the trim air and of the mix manifold air supply satisfy their zone duct-air temperature demands. 中國航空網 www.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：A320飛機維護手冊 AMM AIR CONDITIONING 空調 4(134)
