Measuring device and oil-in-refrigerant content measuring method for compressor system

Abstract

The invention provides a measuring device and an oil-in-refrigerant content measuring method for a compressor system. The measuring device comprises a measuring and adjusting module, a data acquisition module and a control module, wherein the measuring and adjusting module is used for measuring a working condition parameter and a refrigerant parameter of a compressor under a working condition and adjusting the working condition parameter during operation of the compressor; the data acquisition module is used for acquiring the working condition parameter and the refrigerant parameter; and the control module is used for judging the stability of the operating condition of the compressor according to the working condition parameter acquired by the data acquisition module and calculating the oil-in-refrigerant content during operation of the compressor according to the refrigerant parameter when judging that the operating condition of the compressor is in a stable state. According to the measuring device for the compressor system, the oil-in-refrigerant content during operation of the compressor system can be measured accurately, the measuring accuracy is improved, accurate data can be provided for the compressor and related refrigeration equipment, the testing efficiency is improved, and the application range is enlarged.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a measuring device for a compressor system and a method for measuring the oil content of a refrigerant used in the compressor system. Background technique [0002] The oil content of the refrigerant in the working cycle of the compressor has a great influence on the cooling / heating capacity of the refrigeration / heating equipment, the mechanical life of the compressor, the use effect of the capillary tube and the throttling structure, etc. [0003] Generally, for an ideal compressor, the oil content of the refrigerant in its working cycle (that is, the percentage of lubricating oil in the total amount of lubricating oil and refrigerant) should be less than 0.5%. The above-mentioned effects may occur during operation, and the cooling / heating performance will be more seriously affected when the oil content is higher. Therefore, during the development of compressors and their as...
