12、Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the r

13、ight to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedur

14、es used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial r

24、ndards Institute on 2015-02-06.ISO/ASME 14414:2015(E) ISO/ASME 2015 All rights reserved vIntroductionPumping systems account for a significant portion of a facilitys energy consumption in many industries. In the majority of pumping systems the energy added to the working liquid by the pump is much g

25、reater than is required by the process. The excess energy added to the system (e.g. due to throttled control valve) increases heat, noise and vibration but also can bring the systems maintenance costs. The addition of excessive energy to the system often results in over-sizing piping system componen

26、ts such as pumps, process components, and control valves, resulting in an increase in capital costs.This International Standard provides a method to assess pump systems, to identify and quantify pump system energy consumption reduction opportunities and reliability improvement opportunities. It give

27、s a common definition for what constitutes an assessment for both users and providers of assessment services. Its objective is to provide clarity for these types of services which have been variously described as energy assessments, energy audits, energy surveys and energy studies.In all cases, syst

28、ems (energy-using logical groups of equipment organized to perform a specific function) are analysed through various techniques such as measurement, resulting in identification, documentation and prioritization of energy performance improvement opportunities.When contracting for assessment services,

29、 facility personnel may use this International Standard to define and communicate their desired scope of assessment activity to third party contractors or consultants.This International Standard is expected to contribute to decreased energy consumption and consequently to decreased carbon footprint.

30、This International Standard includes the required assessment report content in Annex A. It gives examples of efficient system operation and energy reduction opportunities in Annex B, information on competencies and experiences welcomed to perform audit in Annex C, guidelines for analysis software in

31、 Annex D, a typical example of pre-screening worksheet in Annex E, information on specific energy in Annex F, information on the concept of parasitic power in Annex G and examples of pumping system efficiency indicator in Annex H.This International Standard is developed within the framework of ISO 5

32、0001, ISO 50002 and ISO 50003.ISO/ASME 14414:2015(E)vi ISO/ASME 2015 All rights reservedPump system energy assessment1 ScopeThis International Standard sets the requirements for conducting and reporting the results of a pumping system energy assessment (hereafter referenced as “assessment”) that con

33、siders the entire pumping system, from energy inputs to the work performed as the result of these inputs.The objective of a pumping system energy assessment is to determine the current energy consumption of an existing system and identify ways to improve system efficiency.These requirements consist

34、of organizing and conducting an assessment, analysing the data from the assessment, and reporting and documenting assessment findings.This International Standard is designed to be applied, to open and closed loop pumping systems typically used at industrial, institutional, commercial, and municipal

35、facilities, when requested.This International Standard is focused on assessing electrically-driven pumping systems, which are dominant in most facilities, but is applicable with other types of drivers, such as steam turbines and engines, and drives such as belt.The International Standard does nota)

36、specify how to design a pumping system,b) give detailed qualifications and expertise required of the person using the International Standard although provides a list of body of knowledge in Annex C,c) address the training or certification of persons,d) specify how to implement the recommendations de

37、veloped during the assessment, but does include requirements for an action plan,e) specify how to measure and validate the energy savings that result from implementing assessment recommendations,f) specify how to make measurements and how to calibrate test equipment used during the assessment,g) spe

38、cify how to estimate the implementation cost or conduct financial analysis for recommendations developed during the assessment,h) specify specific steps required for safe operation of equipment during the assessment. The facility personnel in charge of normal operation of the equipment are responsib

39、le for ensuring that it is operated safely during the data collection phase of the assessment,i) address issues of intellectual property, security, confidentiality, and safety.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indi
