GB/T 18429-2018Hermetic scroll refrigerant compressor (English PDF)

Foreword

This standard was drafted according to the rules given in GB/T 1.1-2009. This standard replaces GB/T 18429-2001 "Fully enclosed scroll refrigeration compressor", compared with GB/T 18429-2001 main technologies The content changes as follows:

---Modified the name of the standard and scope of application (see Chapter 1, Chapter 1 of the.2001 edition);

--- Modify the nominal conditions and performance tolerances of the compressor (see 4.2, 5.3.3, 4.1,

5.2.1 of the.2001 version);

--- Increased compressor volume flow requirements and test methods (see 5.3.2, 6.2.2);

--- Increased the evaluation of heating capacity and heating performance coefficient of the compressor (see 5.3.3, 6.2.3);

--- Increased test evaluation of speed-controlled compressors (see Chapter 6);

--- Increased safety requirements and marking requirements for flammable refrigerants (see 5.2, 8.1.3, 8.2.2);

--- Increased airtight inspection requirements and test methods (see 5.3.1, 6.2.1);

--- Modify the compressor internal impurity content, residual moisture content and accelerated life requirements and test methods (see 5.3.4, 5.3.5, 5.3.10, 6.2.4, 6.2.5, 6.2.10, 5.2.8, 5.2.7, 5.2.10, 6.10, 6.9, 6.12) of the.2001 edition;

--- Modify the relevant provisions of the inspection project (see Chapter 7,.2001 version of Chapter 7). This standard is proposed by China Machinery Industry Federation. This standard is under the jurisdiction of the National Refrigeration Air Conditioning Equipment Standardization Technical Committee (SAC/TC238).

--- GB/T 18429-2001. Totally enclosed scroll type refrigerant compressor

1 Scope

GB/T 18429-2018 is the Chinese national standard on hermetic scroll refrigerant compressor, in the field of energy and heat transfer engineering. 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 14 May 2018 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 December 2018. Classification: ICS 27.200, CCS J73. 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 terms and definitions, basic parameters, and technical requirements for a totally enclosed scroll-type refrigerant compressor (hereinafter referred to as "compressor"). Requirements, test methods, inspection rules and signs, packaging, transportation and storage. This standard applies to totally enclosed scroll type refrigerant compressors. This standard does not apply to compressors with refrigerant R744.
