Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 7941-1987 "Refrigeration Unit Test", compared with GB/T 7941-1987, the standard is in the structure, requirements, etc.
There is no obvious correspondence between the two aspects, and the main technical contents are changed as follows.
--- Removed the test provisions, test methods and other related content (see Chapters 2 to 4 of the 1987 edition);
--- Increased the design, construction, commissioning and acceptance requirements for test equipment for refrigeration and air conditioning products and their components (see Chapter 4 to
Chapter 7).
This standard was proposed by the China Machinery Industry Federation.
This standard is under the jurisdiction of the National Refrigeration and Air Conditioning Equipment Standardization Technical Committee (SAC/TC238).
This standard was drafted. Hefei General Environmental Control Technology Co., Ltd., Zhuhai Gree Electric Co., Ltd., York (Wuxi)
Air Conditioning Refrigeration Equipment Co., Ltd., Guangdong Shenling Environmental System Co., Ltd., Zhejiang Zhengli Shengneng Technology Co., Ltd., Hefei General Electromechanical
Product Testing Institute Co., Ltd., Daikin (China) Investment Co., Ltd.
