GB/T 13470-2008Economical operation for the fan system (English PDF)

Foreword

This standard replaces GB/T 13470-1992 "Ventilator System Economic Operation." This standard compared with GB/T 13470-1992 main changes are as follows:

--- Highlight the economic operation of the system transformation measures;

--- The scope of the words "for AC electric drive with a ventilation system, the new system is designed for implementation." Delete the original Standard "applicable to enterprises and institutions";

--- Deleted the original term, increase the "pipeline" of terms and definitions;

--- Increased its equipment, crew, pipe network, the system requirements for running the basic economic requirements;

--- Respectively equipment, units, pipe network, the system proposed specific evaluation methods;

--- Original "excellent, good," "qualified" and "unqualified" to evaluate the term. "Run Economy", "Run reasonable" and "not run economy";

--- Deleted the original concept and calculation method of standard energy efficiency, the use of unit rated unit efficiency and method for comparing the efficiency of As the main basis for discrimination;

--- Increasing the economic operation of the system test method chapter;

--- Proposed separately by management and technical measures. This standard by the National Standardization Technical Committee for Energy and management proposed. This standard is under the jurisdiction of the National Energy Commission on the basis of rational use of electricity points and Management Standardization Technical Committee. Drafting of this standard. Shenzhen real smart Co., Ltd., China National Institute of Standardization, Shenyang Blower Research Institute, a wide set of Guangzhou Pump Co., Ltd. a group. The main drafters of this standard. Zhao Yuejin, Li cattle, Dike Jun, Li Xianrui, PAPTY, Peinian Jiang, Liu Fu Yun. This standard was first published in 1992, this is the first revision. Fan System Economic Operation

1 Scope

GB/T 13470-2008 is the Chinese national standard on economical operation for the fan system, in the field of fluid systems and general-purpose components. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 27 May 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 November 2008. Classification: ICS 23.120, CCS J72. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the basic requirements for the ventilation system AC electric drive economic operation, determination and evaluation methods, test methods and transformation Measures. This standard applies to the fan in the AC drive systems, the new system is designed for implementation.
