    29、ental conditions and human factors on the other. Such data were called for in the NRC report to Congress (2002),(2)and are needed to support ASHRAEs standard setting process. Part I of the project has used the results from past studies and a literature review to guide the development of a measuremen

    30、t system and protocol, and a survey tool. These tools were then pilot tested and validated on four commercial aircraft flights. Part II, which will be under separate contract, will utilize the validated measurement and survey tools to collect data on a statistical sample of aircraft types and routin

    31、gs, and relate the health and comfort survey results from passengers and crew to the air quality and environmental variables observed. In the Part I study reported here, three carry-on instrument packages were developed. Two were suitcases designed to fit under passenger seats. The third package was

    32、 used to make spatial measurements of air speed, temperature, and noise throughout the passenger cabin. The underseat instruments measured temperature, relative humidity, light intensity, motion (acceleration), ozone, carbon dioxide, carbon monoxide, fine particulate matter, volatile organic compoun

    33、ds and semivolatile organic compounds. The instruments are battery powered, independent of aircraft systems, and can be installed and put into operation in 5-10 minutes. The instruments were tested for electromagnetic interference and certified for use aboard commercial aircraft. Two interrelated qu

    34、estionnaires were developed to assess passenger and crew perceptions of health and comfort in the cabin environment. The questionnaires, measurements systems, and procedures were tested on four commercial flights on two participating airlines in April, 2004. Measurements were made on two MD-80 aircr

    35、aft, a 757-200 and a 737-800. Procedures developed to obtain passage through airport security and for preboarding the aircraft worked smoothly. Cooperation with airlines and flight crew was excellent. Passenger and crew acceptance of the onboard measurement systems was excellent. Questionnaire retur

    36、ns averaged 50% for passengers and 71% for flight crew, without incentives. Measurements systems performed well with the exception of the fine particle monitor (malfunction) and passive ozone samplers (operator error). Measurements were made of cabin air throughout each flight from boarding through

    37、deplaning. In addition, short-term measurements of O3, CO, CO2, VOC, and fine particles were made in bleed air for a few minutes during each flight. The data from the four flights have been analyzed empirically and statistically. The statistical analysis was exploratory in nature and was focused on

    38、eight study questions that are proposed for the future Part II study. Results from this exploratory analysis should be useful in the design of the Part II study.

    39、r Quality and Other Factors to Comfort and Health Symptoms Reported by Passengers and Crew on Commercial Transport Aircraft (Part I) (ASHRAE Project 1262-TRP) INTRODUCTION The aircraft cabin is a challenging microenvironment for maintaining the health, comfort, and well-being of passengers and crew.

    40、 Space is limited, conditions can feel cramped, the outside environment is extreme, and travelers experience anxiety over loss of control over their situation and their environment. During flight the passengers and crew experience noise, reduced atmospheric pressure, vibration, low relative humidity

    41、, somewhat variable temperature, and potential air quality degradation. It is perhaps not surprising that passengers and crew have registered complaints about the aircraft cabin environment for decades. A number of studies have been conducted to investigate these complaints. The National Research Co

    42、uncil (NRC) studied the issue of commercial aircraft cabin air quality and issued reports in 1986(1)and 2002.(2)The 2002 report(2)recommended “ rigorous scientific investigation to ensure that the regulations governing air quality in commercial aircraft cabins are adequate to protect public health”.

    43、 ASHRAE recommends ventilation standards for public buildings, residences, and commercial aircraft among its many activities. These latter standards influence the air quality and therefore, the comfort and health of aircraft cabin occupants. Aircraft manufacturers and airlines attempt to balance cab

    44、in environmental factors which affect comfort with economic realities that affect their competitive position. For example, providing more leg room decreases passenger load which tends to drive up ticket prices, and in the same manner, providing additional ventilation requires energy to heat and filt

    45、er the air, tending to raise the per-passenger cost. The ventilation standards provide a basis for assuring cabin occupants a safe and comfortable environment. As technologies change and new information emerges, the standards are reviewed and revised if necessary. As part of its effort to review air

    46、craft cabin ventilation standards, ASHRAE has supported previous research into the aircraft cabin environment.(3,4)ThisfileislicensedtoAshraeAssociate(associateashrae.org).ThisdownloadwasmadeavailablewithsupportfromASHRAE.CopyrightASHRAE2017.2The present study is the first part of a two-part program

    47、 to greatly expand the database on the in-service aircraft cabin environment, and the comfort and health perceptions of passengers and crew. The program is being developed in collaboration with FAA and with input from many stakeholders. Part I is developing and testing instrumentation and survey too

    48、ls for use on commercial aircraft; Part II will gather data and survey passengers and crew on a substantial number of flights to obtain required information with an appropriate degree of statistical confidence. This report describes Part I of ASHRAE Project 1262-TRP entitled “Air Quality and Other F

    49、actors Relating to Comfort and Health Related Symptoms Reported by Passengers and Crew on Commercial Transport Aircraft”. Under Part I we have initiated the development of a study design for Part II of the project. In order to ensure that the data collected within Part II of the study meet ASHRAEs needs, we implemented the Data Quality Objectives (DQO) process.(5)The DQO Process comprises seven procedural steps used to clarify study
