21、Guideline 23-2016(This foreword is not part of this guideline. It is merelyinformative and does not contain requirements necessaryfor conformance to the guideline.)FOREWORDThis guideline was developed in response to a need expressedwithin the rail passenger vehicle industry to adopt a moreconsistent

22、 approach to the design and application of heating,ventilating, and air-conditioning systems in rail passengervehicles that can be used as a basis for future designs. Thisneed evolved from informal discussions among the rail vehi-cle industrys operating, supply, and technical support mem-bers and se

23、veral different professional committees that workto address rail passenger vehicle issues, including the Ameri-can Public Transit Association (APTA), the American Societyof Mechanical Engineers (ASME), and the Rail Transit Stan-dards Committee (RTSC), a Division of the Institute of Elec-trical and E

24、lectronics Engineers (IEEE). Current inconsistent design approaches and sometimeswidely varying requirements for similar applications haveresulted in minimal standardization, excessive developmentefforts for similar equipment, and the resulting inefficiency anddisproportionately high cost of equipme

25、nt. In an attempt to findan approach that would address the concerns of all interestedparties, participation was solicited from different areas of theindustry, including operating authorities, supply industry,labor, government regulatory authorities, and the industry con-sulting community. Based on

26、the interest of persons and entitiesin participating in this effort it was further agreed to form anASHRAE Guideline Project Committee (GPC) under the super-vision of ASHRAE Technical Committee (TC) 9.3, Transporta-tion Air Conditioning to perform this task.This document conveys what GPC 23 has join

27、tly deter-mined through experience and successful practice to be tech-nically appropriate and reasonable design, application, andtesting guidelines for this equipment. 1.
