A method for screening refrigerator compressor refrigeration capacity comparison test standard prototype

Abstract

The invention discloses a method for screening standard model machines for a refrigerator compressor refrigeration capacity comparison test. The method comprises the following steps: selecting the number of refrigerator compressors of the same type, meeting refrigeration capacity requirements, of a manufacturer as preliminarily selected samples; connecting the preliminarily selected samples into a test refrigeration loop; in a set working condition, performing a stability test and a repeatability test; and selecting out refrigerator compressors with stability test data and repeatability test data meeting the requirements as the standard model machines for the refrigerator compressor refrigeration capacity comparison test. According to the method, the standard model machines for the refrigerator compressor refrigeration capacity comparison test are selected out by adopting the stability test and the repeatability test pioneered in test field, and a refrigerator compressor refrigeration capacity detection platform can be constructed between each refrigerator compressor manufacturing plant and a detection mechanism, so that the detection of the refrigerator compressor refrigeration capacity is standardized and normalized, the refrigeration capacity test uniformity of refrigerator compressor industries is improved, and the industrial exchange and platform construction are facilitated.

Description

technical field [0001] The invention relates to a method for screening standard prototypes for comparison testing of refrigeration capacity of refrigerator compressors, which can screen out standard prototypes for comparative testing of refrigeration capacity of refrigerator compressors. Background technique [0002] With the rapid development of the economy, at this stage, refrigerator products have entered thousands of families and become one of the indispensable household appliances in the daily life of the public. The compressor is one of the core components of the refrigerator product, and its performance plays a vital role in the overall performance of the refrigerator. [0003] At present, all major refrigerator compressor manufacturers will test the cooling capacity of the refrigerator compressors produced. However, since the performance test data of each manufacturer does not have a unified platform, the reliability of the test data cannot be approved. Therefore, in...

Problems solved by technology

[0004] However, domestic comparison methods and comparison platforms for refrigerator compressor products are still in the missing stage. As a result, major refrigerator compressor manufacturers claim that they have the ability to test the cooling capacity of refrigerator compressors. However, Since there is no authoritative platform for inspection, the cooling capacity test values ​​of refrigerator compressors they claim cannot form a unified communication platform due to various errors, which seriously restricts the further development of the compressor industry.

[0005] How to prepare a standard prototype that can be used for the comparison test of the refrigeration capacity of refrigerator compressors, there is currently no effective and feasible solution in this industry, which has become a technical problem that needs to be solved urgently in this industry
