DIN EN ISO 11011:2015-08 EN ISO 11011:2015 (E) 4 IntroductionThis International Standard ha
27、s been developed with reference to available documentation1)(see Bibliography) relating to energy assessment of compressed air systems.This International Standard is produced to support the objectives of energy management for those organisations utilizing compressed air and wishing to improve the en
28、ergy efficiency of such systems. Remembering the words of Lord Kelvin who said in 1883, “If you cannot measure it, you cannot improve it”, this International Standard aims to assist with measurement and provide the knowledge to enable improvement.The prime consideration for any compressed air system
29、 is the ability to generate air with the least amount of energy. Having done this, the next consideration is to transmit energy from the point of generation to the point of use with the least loss. The final consideration is to eliminate waste and use the least amount of air for the production proce
30、ss.This International Standard uses speciality terms which relate the needs of assessment activities to those of compressed air systems. Many terms will appear new to the users of this International Standard who are familiar with general compressed air terms.A general introduction to energy assessme
31、nt is given in Annex A.1) Extracts from ASME EA-4-2010 were used with permission from ASME.

33、ssessment (hereafter referenced as an “assessment”) that considers the entire system, from energy inputs to the work performed as the result of these inputs.This International Standard considers compressed air systems as three functional subsystems: supply which includes the conversion of primary en
34、ergy resource to compressed air energy; transmission which includes movement of compressed air energy from where it is generated to where it is used; demand which includes the total of all compressed air consumers, including productive end-use applications and various forms of compressed air waste.T
35、his International Standard sets requirements for analysing the data from the assessment, reporting and documentation of assessment findings, and identification of an estimate of energy saving resulting from the assessment process.This International Standard identifies the roles and responsibilities
36、of those involved in the assessment activity.This International Standard provides indicative information in Annexes B, C, D, and E of the type of data to be collected to assist in a successful assessment. The information provided is not exhaustive and therefore is not intended to restrict the inclus
37、ion of other data. The form and presentation of the information given in the annexes is also not intended to restrict the manner of presentation of the reporting to the client.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indi
