24、ces commonly occupied by peo-ple. Occupant density is typically high, and occupant activitylevels range from almost completely sedentary (passengers)to very active (flight attendants). Aircraft passengers andcrew make up a wide cross section of the general population,ranging from the very young to t

25、he very old, from the healthyto the infirm, and from frequent fliers to inexperienced fliers.In addition, the aircraft must be regarded as both a publicplace (passengers) and a workplace (crew). A unique aspectof the aircraft environment is that, unlike many other indoorenvironments, including those

26、 for some other modes of trans-portation, occupants do not have the ability to remove them-selves from the environment. The controlled atmosphereaboard the aircraft in flight is at a lower pressure and relativehumidity than that found in many other environments. Fur-ther, unlike other indoor environ

27、ments, the outside airintended for ventilation is first compressed and heated in theaircraft engines/APU, creating the potential for engine-sourced and entrained compounds to contaminate the cabinair. The environment outside the aircraft in flight is hostile tohuman life and, while aircraft are oper

28、ated with the comfortof passengers and crew in mind, their safety and health mustalways be paramount.This standard addresses these unique characteristics ofaircraft cabin environments as well as characteristics that arecommon to many other indoor environments. The scope ofthis standard references 14

29、CFR25 to define the category ofaircraft to which the standard applies. It is not intended toexclude aircraft of the same category certified in other juris-dictions. The term “commercial aircraft” as used in this stan-dard refers to aircraft engaged in common carriage asdefined in the Airworthiness H

30、andbook, Order 8300.10, Vol-ume 2, Chapter 60, Section 5 (U.S. Federal Aviation Adminis-tration, Department of Transportation, U.S. GovernmentPrinting Office, Washington, DC, October 2006).Standard 161 is updated using ASHRAEs continuousmaintenance procedures. According to these procedures, thestand

31、ard is continuously revised by addenda that are publiclyreviewed, approved by ASHRAE and ANSI, and publishedand posted for free on the ASHRAE website. Instructions andforms for submitting a proposed change can be found at theend of the standard.1. PURPOSEThis standard defines the requirements for ai

32、r quality inair-carrier aircraft and specifies methods for measurement andtesting in order to establish compliance with the standard.2. SCOPE2.1 This standard applies to commercial passenger air-carrieraircraft carrying 20 or more passengers and certified underTitle 14 CFR Part 25.12.2 This standard

33、 considers chemical, physical, and biologi-cal contaminants as well as moisture, temperature, pressure,and other factors that may affect air quality.2.3 Because this standard cannot take into account everyvariable, especially those relating to safe operation of the air-craft, the diversity of source

34、s and types of contaminants inaircraft cabin air, and the range of susceptibility in the popu-lation, compliance with this standard will not necessarilyensure acceptable aircraft cabin air quality for everyone.3. DEFINITIONSair, ambient: the outside air surrounding the aircraft.air, engine bleed: ai

35、r extracted from the compressor stages ofgas turbine propulsion engines and auxiliary power units.air, outside: as used in this standard, this term always refersto ambient air supplied to the aircraft cabin by the environ-mental control system.air, recirculated: air from the aircraft passenger cabin

36、 that isreused as part of the supply air.air, supply: air delivered to the aircraft cabin and used forpressurization, ventilation, temperature control, and humiditycontrol.air-conditioning system (packs): a part of the environmentalcontrol system, typically pneumatically powered, that providescoolin

37、g and heating for aircraft cabin temperature control.aircraft, commercial: an aircraft engaged in common car-riage according to FAA 8300:10.2auxiliary power unit (APU): a gas-turbine powered unit thatprovides electrical power and compressed air to operate air-craft systems independent of the aircraf

38、t propulsion engines.cabin: a term applied to any spaces in the aircraft occupied bypassengers or crew members.cabin altitude: the effective altitude to which the aircraftcabin is pressurized.cabin pressure control system (CPCS): part of the environ-mental control system that regulates cabin altitud

39、e.contaminant: an airborne constituent that may reduce accept-ability of the air.cockpit: see flight deck.environmental control system (ECS): the equipment in anaircraft used to pressurize, ventilate, air condition, dehumid-ify, or humidify the aircraft cabin. It includes cabin-supplyairflow control

40、, temperature control, distribution, recircula-tion, and filtration.flight: a term used in this standard to describe the status of theaircraft anytime it is not in contact with the ground.

42、t operation. Also referred to as the“cockpit.”ground operations: a term used in this standard to describethe status of the aircraft anytime it is in contact with theground and is occupied by any passengers or at least one crewmember.occupiable space: space that is within the pressurized cabinand int

43、ended for human activities. Spaces with equipmentthat is periodically maintained but not normally attended arenot considered occupiable.ozone converter: a part of the environmental control systemor air-conditioning system used to reduce the ozone present inthe outside air supply to acceptable levels

44、 for cabin occupantrespiration.pack burn: the practice of operating the air-conditioningpacks and/or pneumatic system at a high temperature settingintended to clean suspected contamination from the inside ofthe high pressure environmental control components.personal airflow outlet (PAO): an adjustab

45、le air supply noz-zle located at each passenger seat overhead console or crewstation and individually controlled by the passenger or crewmember. Also commonly known as a “gasper” or an individ-ual outlet.ventilation: the process of supplying air to or removing itfrom a space for the purpose of contr

46、olling air contaminantlevels, cabin pressure, humidity, airflow patterns, and temper-ature within the space.ventilation effectiveness (VE): for the purpose of this stan-dard, VE is defined as the fraction of the outside air deliveredto the space that reaches the breathing zonethe regionwithin the oc

47、cupied space that is located between planes 3 in.(75 mm) and 72 in. (1830 mm) above the floor and 2 or morein. (50 or more mm) from the wall.ventilation, total: the sum of the outside air and recirculatedair supplied to the aircraft cabin and other occupied spaces.4. COMPLIANCETo comply with this st

48、andard, the requirements of Sec-tions 5, 6, 7, 8, and 9 shall be met. This standard is intendedto be independent of specific aircraft systems and equipment.Applying this standard requires some knowledge of com-mon aircraft environmental control systems and equipment.Descriptions of common environmen

49、tal controls systems andequipment may be found in Chapter 10 of the 2011 ASHRAEHandbookHVAC Applications.35. GENERAL REQUIREMENTSExcept where specified otherwise, Section 5 and its sub-sections apply anytime the aircraft is occupied by passengersor crew members. When the cabin is divided into parts by par-titions, curtains, seating density, or temperature control zones,the requirements of Section 5 and its subsections apply toeach such part of the cabin. These requirements also apply tothe flight deck.5.1 Pressure. This section addresses aircraft compartmentpressuri
