24、al are notoffered the right to appeal at ASHRAE or ANSI.)FOREWORDWhen the potential link between release of chlorofluoro-carbons (CFCs) and depletion of stratospheric ozone wasfirst discovered, ASHRAE appointed a task group to studythe issue and to develop appropriate policy and program rec-ommendat

25、ions to the Board of Directors. In response, a com-prehensive action program was initiated. It includedresearch, education, communication, and training directedtoward the various aspects of the CFC issue.A part of this program was the development of a guide-line for reducing CFC refrigerant release.

26、 This was pub-lished as ASHRAE Guideline 3-1990, Reducing Emission ofFully Halogenated Chlorofluorocarbon (CFC) Refrigerantsin Refrigeration and Air-Conditioning Equipment and Appli-cations.C1Since that date, it has been determined that allreleases of chlorine-containing refrigerants, hydrochloroflu

27、-orocarbons (HCFCs) as well as CFCs, contribute to deple-tion of the stratospheric ozone layer. Not long after, it wasalso determined that the release of CFCs, HCFCs, andhydrofluorocarbons (HFCs) contributes to global warming,adding new urgency to controlling their release. In 1996,Guideline 3 was r

28、evised to reflect this need for a more strin-gent policy, and in 2002 ASHRAE published Standard 147,Reducing the Release of Halogenated Refrigerants fromRefrigerating and Air-Conditioning Equipment and Sys-tems.C2Standard 147 took many of the recommended prac-tices of Guideline 3 and made them manda

29、tory requirements,thus further increasing the stringency of the guideline, whichwas later withdrawn. However, some of the material fromGuideline 3 was preserved in the standard in informativeappendices that provide recommended practices that are notrequired by the standard.This revision of Standard

30、147 updates the 2002 editionby expanding the number of equipment types and systemscovered by providing significant requirements for field-erected systems, by adding more sections on leak checking,by adding requirements for systems with larger charges, byaddressing the shipping and handling of contai

31、ners forrefrigerants, and by making many formerly recommendedpractices mandatory.1. PURPOSEThis standard establishes practices and procedures thatwill reduce the inadvertent release of halogenated refriger-ants.2. SCOPEThe practices and procedures in this standard coverrelease reduction of halogenat
