Consensus is defined by the American National StandardsInstitute (ANSI)
7、, of which ASHRAE is a member and which has approved this standard as an ANS, as “substantial agreement reachedby directly and materially affected interest categories. This signifies the concurrence of more than a simple majority, but not necessarilyunanimity. Consensus requires that all views and o
8、bjections be considered, and that an effort be made toward their resolution.”Compliance with this standard is voluntary until and unless a legal jurisdiction makes compliance mandatory through legislation.ASHRAE obtains consensus through participation of its national and international members, assoc
9、iated societies, and publicreview.ASHRAE Standards are prepared by a Project Committee appointed specifically for the purpose of writing the Standard. TheProject Committee Chair and Vice-Chair must be members of ASHRAE; while other committee members may or may not be ASHRAEmembers, all must be techn
10、ically qualified in the subject area of the Standard. Every effort is made to balance the concerned interestson all Project Committees.

23、 STANDARD 134-2005 3(This foreword is not part of this standard. It is merelyinformative and does not contain requirements necessaryfor conformance to the standard. It has not been pro-cessed according to the ANSI requirements for a stan-dard and may contain material that has not been subjectto publ
24、ic review or a consensus process. Unresolvedobjectors on informative material are not offered theright to appeal at ASHRAE or ANSI.)FOREWORDThis standard provides a comprehensive set of symbolsfor use in drawings and other documents relating to the designof heating, ventilating, air-conditioning, an
25、d refrigerating(HVAC&R) systems. The symbols are intended to be usable inboth the manual and automatic (CAD system) creation ofdrawings.To develop this standard, the project committee surveyedsymbols solicited from governments, standards organizations,and consultants from around the world. While the
26、 committeefound general agreement in some areas of symbol usage andsymbolic practice, it discovered wide variation in others. Thisstandard therefore intends to establish a common symbol lan-guage for use in HVAC&R drawings, thereby facilitating theunderstanding of these documents and making them acc
27、essi-ble to a wider variety of users. It is anticipated that as the useand understanding of these symbols increase, the accuracyand efficiency with which engineering drawings are translatedinto actual systems will also increase.This standard is intended for international use. The text,fonts associat
28、ed with a symbol, and description box in thetables should be translated into the language of the standard.The filename alpha character should not be changed. The useof I-P (inch-pound) or SI (Standard International) metric unitsshould be used where dual units are shown in the text or with asymbol.Th
29、is standard will be under continuous maintenance byASHRAE, allowing it to be updated on a regular and ongoingbasis. Continuous maintenance permits input from users andallows the standard to reflect the changes occurring in tech-nology and engineering practices.1. PURPOSEThe purpose of this standard
30、is to define graphic symbolsfor heating, ventilating, air-conditioning and refrigeratingsystems.2. SCOPE2.1 This standard covers graphic symbols for heating, ven-tilating, air-conditioning, and refrigerating systems andequipment, including related controls.2.2 This standard identifies graphic symbol
31、s by name, con-figuration, and description.2.3 The graphic symbols in this standard are intended foruse in manual drawings and drawings produced by computer-aided drafting (CAD).3. DEFINITIONS3.1 Definitions of terms used in this standard may be foundin ASHRAE Terminology of Heating, Ventilation, Ai
32、r Condi-tioning, and Refrigeration.13.2 Additional terms used in this standard but not found inASHRAE Terminology are defined in this section.accessories (controls): equipment such as air compressors,air line dryers, compressed air filters, and indicating devices(pressure and temperature) to facilit
