GB/T 9098-2008Hermetic motor-compressors for refrigerators (English PDF)

Foreword

This Standard replaces GB/T 9098-1996 "Hermetic Motor - Compressors for

Refrigerators".

Compared with GB/T 9098-1996, the main technical changes in this Standard are as

follows.

- the R12 refrigerant compressor in "Application Scope" was replaced by R600a

and R134a refrigerant compressors;

- the terms and definitions of rated parameter, variable speed (variable frequency)

compressor, and variable capacity compressor were added;

- the classifications of speed control and capacity change were added in the

product classification;

- the basic contents of expression methods for compressor specification and model

were specified;

- the requirements of product technical specification were added in the technical

requirements, indicating the rated parameters and test conditions of technical

indexes such as product refrigerating capacity and coefficient of performance

(COP) of the manufacturer;

- the grading of all performance indexes of compressor by nominal working volume

of cylinder was replaced by nominal refrigerating capacity;

- the nominal coefficient of performance (COP) of compressor was graded by

efficacy level;

- the performance indexes, test methods, and assessment contents of variable

speed (variable frequency) compressor were added;

- the requirements of compressor inclining starting test were added;

- the determination methods for residual moisture content and internal impurity

content of the complete un-oiled compressor were specified;

- the test methods and assessment contents for capillary tube plugging rate of

R134a refrigerant compressor were added;

- the requirements of "motor winding temperature" and "shell temperature" were

replaced according to the relevant contents in GB 4706.17 "Household and

Similar Electrical Appliances - Safety - Particular Requirements for

Motor-Compressors";

- the fire warning sign for combustible refrigerant compressor was added.

This Standard was proposed by China National Light Industry Council.

This Standard shall be under the jurisdiction of National Technical Committee on

Hermetic Motor - Compressors for

Refrigerators

1 Scope

This Standard specifies the terms and definitions, product classification, technical

requirements, test methods, inspection rules and the requirements of marking,

packaging, transportation and storage of hermetic motor-compressors for refrigerators.

The safety requirements of compressor are detailed in GB 4706.17 "Household and

Similar Electrical Appliances - Safety - Particular Requirements for

Motor-Compressors".

This Standard is applicable to the hermetic motor-compressors used for

low-back-pressure * household and similar electric refrigerators with R600a and

R134a refrigerants, and the nominal refrigerating capacity not exceeding 400 W under

the specified working conditions in this Standard (hereinafter referred to as

"compressor").

For similar compressors with other types of refrigerants, this Standard may also be

referred to.

This Standard is not applicable to vehicular refrigerator compressors.
