Problems solved by technology

However, if the high-parameter single-atom working medium equipment is directly loaded into the system device for debugging, since the high-parameter single-atom working medium equipment has functional uncertainty, and the high-parameter single-atom working medium equipment is the key equipment in the system. Important functions, once the performance or reliability of the high-parameter single-atom working fluid equipment has problems, not only the risk of the equipment itself will occur, but also bring hidden safety hazards to the entire system device
In addition, the application scenarios of high-parameter single-atom working medium equipment are often single-working conditions, and it is difficult to provide guidance for establishing the internal relationship between the actual performance and design performance of high-parameter single-atom working medium equipment. The relationship between design performance and actual performance can only be understood by performing performance tests of working fluid equipment under various working conditions, and the relationship between design performance and actual performance can be used as a reference for optimizing equipment design tools and methods

Abstract

The invention discloses a performance test system for high-parameter single-atom working fluid equipment, which includes a gas source unit, a pre-cooling heat exchanger, a main circuit compressor, a test compressor, a low-temperature heat exchanger, a test heat exchanger, and a water-cooled heat exchanger. Heater; the test compressor is connected in parallel with the main circuit compressor; the test heat exchanger is connected in parallel with a test heat exchanger bypass. The present invention can realize the individual performance test and joint performance test of the test compressor and the test heat exchanger, and simulate the actual working conditions by performing a closed cycle of the single-atom working fluid in a high-parameter state exceeding the critical pressure and temperature. conditions and test the performance parameters of related equipment.

Description

technical field [0001] The invention relates to the technical field of equipment performance testing using single-atom working medium as the operating medium, in particular to a performance test system for high-parameter single-atom working medium equipment. Background technique [0002] Single-atom working fluids usually refer to simple rare gases, such as helium, neon, argon, etc., which are difficult to chemically react with other substances. High parameters refer to high temperature and high pressure. The working substance refers to the medium substance used by various heat engines or thermal equipment to complete the mutual conversion of thermal energy and mechanical energy. Due to the low critical temperature and critical pressure of the single-atom working fluid, it is easy to be in a supercritical state in a high-temperature, high-pressure, high-parameter environment. In this state, the single-atom working fluid often has fluid density, viscosity, solubility, A phe...
