Foreword

This Standard was drafted as per the rules specified in GB/T 1.1-2009. This Standard replaced GB 19153-2009 Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Displacement Air Compressors. Compared with GB 19153-2009, this Standard has the following major technical changes besides the editorial modifications.

--- Adjust the scope of the standard (see Clause 1 of this Edition; Clause 1 of 2009 Edition);

--- Change the terms from actual volume flow rate to volume flow rate of packaged compressor; from input power of air compressor to power of air compressor; from input specific power of air compressor to the specific power of air compressor (see 3.1, 3.2,

3.3 of this Edition; 3.1, 3.2,

3.3 of 2009 Edition);

--- Add the definition of variable speed rotary air compressor (see

3.5 of this Edition);

--- Delete the target energy efficiency limit value of air compressor and the energy saving evaluation value of air compressor (3.5,

3.6 of 2009 Edition);

--- Increase the energy efficiency indicators for some products (see Table 1, Tables 3~6 of this Edition; Tables 1~7 of 2009 Edition);

--- Add the energy efficiency evaluation of variable speed oil-injected rotary compressor (see

4.2 of this Edition);

--- Unify the energy efficiency indicators of general-use oil-injected screw air compressor, oil-injected scroll air compressor, oil-injected vane air compressor into the energy efficiency indicators of general-use oil-injected rotary air compressor (see Tables 1 and 2 of this Edition; Tables 6 and 7 of 2009 Edition);

--- Unify the energy indicators of miniature, general-use reciprocating piston air compressor into the energy efficiency indicators of reciprocating piston air compressor (see Table 3 of this Edition; Tables 3 and 5 of 2009 Edition);

1 Scope

GB 19153-2019 is the Chinese national standard on minimum allowable values of energy efficiency and energy efficiency grades for displacement air compressors, in the field of energy and heat transfer engineering. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 31 December 2019 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 July 2020. Classification: ICS 27.010, CCS F01. 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 energy efficiency grades, energy efficiency limit values, test and calculation methods for the displacement air compressors. This Standard is applicable to.
