18、This document provides a standardized framework for conducting an energy assessment of pumping systems, here-after referenced as an “assessment.” A pumping system is defi ned as one or more pumps and those interacting or interrelating elements that together accomplish the desired work of moving fl u
19、id. A pumping system thus generally includes pump(s), driver, drives, distribution piping, valves, sealing systems, controls, instrumentation, and end-use equipment such as heat exchangers. Assessments involve collecting and analyzing system design, operation, energy use, and performance data and id
20、entifying energy performance improvement opportunities for system optimization. An assessment may also include additional information, such as recommendations for improving resource utilization, reducing per unit production cost, reducing life-cycle costs, and improving environmental performance rel
21、ated to the assessed system(s).This Standard provides a common defi nition for what constitutes an assessment for both users and providers of assessment services. The objective is to provide clarity for these types of services which have been variously de-scribed as energy assessments, energy audits
22、, energy surveys, and energy studies. In all cases, systems (energy-using logical groups of industrial equipment organized to perform a specifi c function) are analyzed through various tech-niques such as measurement, resulting in the identifi cation, documentation, and prioritization of energy perf
23、ormance improvement opportunities. This Standard sets the requirements for conducting and reporting the results of an assessment that considers the entire system, from energy inputs to the work performed as the result of these inputs. An assessment complying with this Standard need not address each
24、individual system component or subsystem within an industrial facility with equal weight; however, it must be suffi ciently comprehensive to identify the major energy effi ciency opportunities for improving the overall energy performance of the system. This Standard is designed to be applied primari
25、ly at indus-trial facilities, but many of the concepts can be used in other facilities such as those in the institutional, commercial, and municipal sectors. This Standard is part of a portfolio of documents and other efforts designed to improve the effi ciency of industrial facilities. Initially, a
26、ssessment standards are being developed for compressed air, process heating, pumping, and steam systems. Other related existing and planned efforts to improve the effi ciency of industrial facilities include(a) ASME guidance documents for the assessment standards, which provide technical background
27、and applica-tion details to support understanding of the assessment standards. These guidance documents provide rationale for the technical requirements of the assessment standards and give technical guidance, application notes, alternate approaches, tips, techniques, and rules-of-thumb.(b) a certif
28、i cation program for each ASME assessment standard that recognizes certifi ed practitioners as individu-als who have demonstrated, via a professional qualifying exam, that they have the necessary knowledge and skills to properly apply the assessment standard.(c) an energy management standard, “A Man
29、agement System for Energy, ANSI/MSE 2000:2008,” which is a stan-dardized approach to managing energy supply, demand, reliability, purchase, storage, use, and disposal, and is used to control and reduce an organizations energy costs and energy-related environmental impact. Note: This ANSI standard wi
30、ll eventually be superseded by ISO 50001, now under development.(d) an ANSI-accredited measurement and verifi cation protocol that includes methodologies for verifying the results of energy effi ciency projects.(e) a program, Superior Energy Performance, that will offer ANSI-accredited certifi catio
31、n for energy effi ciency through application of ANSI/MSE 2000:2008 and documentation of a specifi ed improvement in energy performance using the ANSI measurement and verifi cation protocol.The complementary documents described above, when used together, will assist organizations seeking to establish
32、 and implement company-wide or site-wide energy plans.ASME EA-22009 was approved by the EA Industrial System Energy Assessment Standards Committee on October 1, 2009 and approved by the American National Standards Institute (ANSI) on December 2, 2009.vEA INDUSTRIAL SYSTEM ENERGY ASSESSMENT STANDARDS

42、MS1 SCOPE AND INTRODUCTION1.1 ScopeThis Standard covers pumping systems, which are defi ned as one or more pumps and those interacting or interrelating elements that together accomplish the de-sired work of moving a fl uid. A pumping system thus generally includes pump(s), driver, drives, distributi
43、on piping, valves, sealing systems, controls, instrumenta-tion, and end-use equipment such as heat exchangers. This Standard addresses open and closed-loop pumping systems typically used in industry, and is also applicable to other applications.This Standard sets the requirements for conducting and
44、reporting the results of a pumping system assess-ment (hereafter referenced as an “assessment”) that con-siders the entire pumping system, from energy inputs to the work performed as the result of these inputs. An as-sessment complying with this Standard need not address each individual system compo
45、nent or subsystem within an industrial facility with equal weight; however, it must be suffi ciently comprehensive to identify the major ef-fi ciency improvement opportunities for improving the overall energy performance of the system. This Standard is designed to be applied primarily at industrial
46、facilities, but many of the concepts can be used in other facilities such as institutional, commercial, and water and waste-water facilities.Assessments involve collecting and analyzing system design, operation, energy use, and performance data, and identifying energy performance improvement op-port
47、unities for system optimization. An assessment may also include other information, such as recommendations for improving resource utilization, reducing per unit production cost, reducing life-cycle costs, and improv-ing environmental performance related to the assessed system(s). Assessment activiti
48、es may include, but are not limited to, engaging facility personnel and provid-ing information about the assessment process; collecting and analyzing data on system design, operation, energy use, and performance; identifying energy performance improvement opportunities; and making recommenda-tions f
49、or system improvement and implementation in a written report. This report should document system design; quantify energy consumption and performance data; document the assessment process; show results, recommendations and savings projections; and improve facility personnels understanding of system energy use and operation.All system assessments start with identifying the ul-timate goal of the system. When the ultimate goal of the system has been established, the assessment continues to investigate how well-suited the existing system is to deliver the needed output from the per
