Consensus is definedby the American National Standards Institute (ANS

6、I), of which ASHRAE is a member and which has approved this Standard as an ANS, as“substantial agreement reached by directly and materially affected interest categories. This signifies the concurrence of more than a simple majority,but not necessarily unanimity. Consensus requires that all views and

7、 objections 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, as

8、sociated societies, and public review.ASHRAE Standards are prepared by a Project Committee appointed specifically for the purpose of writing the Standard. The ProjectCommittee Chair and Vice-Chair must be members of ASHRAE; while other committee members may or may not be ASHRAE members, allmust be t

9、echnically qualified in the subject area of the Standard. Every effort is made to balance the concerned interests on all Project Committees.

It is merely informative and does not contain requirements necessary for conformance to the standard. It has not been pro-cessed according to the ANSI requirements for a s

20、tandard and may contain material that has not been subject to public review or a consensus process. Unresolved objec-tors on informative material are not offered the right to appeal at ASHRAE or ANSI.)FOREWORDThis addendum simplifies Normative Appendix A, “Methods for Determining Operative Temperatu

21、re,” to be a single proce-dure for calculating operative temperature. Case 1 is removed because it is overly permissive, and Case 3 is removed because it is redundant with Case 2.Note: In this addendum, changes to the current standard are indicated in the text by underlining (for additions) and stri

22、kethrough (for deletions) unless the instructions specifi-cally mention some other means of indicating the changes.Addendum c to Standard 55-2013Revise Normative Appendix A as follows.(This is a normative appendix and is part of this stan-dard.)NORMATIVE APPENDIX AMETHODS FOR DETERMININGOPERATIVE TE

23、MPERATUREDetermine operative temperature (to) in accordance with one of using the following casesmethod or Chapter 9 of ASHRAE HandbookFundamentals.3Note: Average air speed and average air temperaturehave precise definitions in this standard. See Section 3 for all defined terms.Case 1: Average air t

24、emperature (ta) is permitted to be used in place of operative temperature (to) when these three conditions are met:a. There is no radiant and/or radiant panel heating or radiant panel cooling system.b. The area weighted average U-factor of the outside win-dow/wall satisfies the following inequality:

25、UW50td ,itd ,e- (SI)UW15.8td ,itd ,e- (IP)whereUw= average U-factor of window/wall, W/m2K (Btu/h ft2 F)td,i= internal design temperature, C (F)td,e= external design temperature, C (F)c. Window solar heat gain coefficients (SHGC) are less than 0.48.Case 2: Calculation of the operative temperature (to

26、) is based on average air temperature (ta) and mean-radiant tem-perature.Operative temperature (to) is permitted to be calculated per the following formula: toAta1 Atr+=whereto= operative temperatureta= average air temperaturetr= mean radiant temperature (For detailed calculation procedures see the

27、“Thermal Comfort” chapter of most current edition of ASHRAE HandbookFundamentals3.)A can be selected from the following values as a function of the relativeaverage air speed vr(Va).vrVa0.2 m/s(40 fpm)0.2 to 0.6 m/s(40 to 120 fpm)0.6 to 1.0 m/s(120 to 200 fpm)A 0.5 0.6 0.7Case 3: For representative o

31、ctivities on both the indoor and outdoor environment.ASHRAEs members will strive to minimize any possible deleterious effect on the indoor and outdoor environment ofthe systems and components in their responsibility while maximizing the beneficial effects these systems provide,consistent with accept

32、ed Standards and the practical state of the art.ASHRAEs short-range goal is to ensure that the systems and components within its scope do not impact theindoor and outdoor environment to a greater extent than specified by the Standards and Guidelines as established byitself and other responsible bodi

33、es.As an ongoing goal, ASHRAE will, through its Standards Committee and extensive Technical Committee structure,continue to generate up-to-date Standards and Guidelines where appropriate and adopt, recommend, and promotethose new and revised Standards developed by other responsible organizations.Thr

34、ough its Handbook, appropriate chapters will contain up-to-date Standards and design considerations as thematerial is systematically revised.ASHRAE will take the lead with respect to dissemination of environmental information of its primary interest andwill seek out and disseminate information from

35、other responsible organizations that is pertinent, as guides to updatingStandards and Guidelines.The effects of the design and selection of equipment and systems will be considered within the scope of thesystems intended use and expected misuse. The disposal of hazardous materials, if any, will also

36、 be considered.ASHRAEs primary concern for environmental impact will be at the site where equipment within ASHRAEs scopeoperates. However, energy source selection and the possible environmental impact due to the energy source andenergy transportation will be considered where possible. Recommendation

37、s concerning energy source selectionshould be made by its members. ASHRAE (www.ashrae.org). For personal use only.
