AI Technical Summary

Technical Problem

The existing AHRI ten-coefficient model relies on measured data of specific compressors, has weak generalization ability, and cannot be applied to automotive volumetric compressors with different displacements, speeds, structures, and refrigerants. Furthermore, it cannot predict power consumption in the early stages of compressor development and selection.

Method used

By obtaining the discharge pressure, suction pressure, and speed of the target compressor, the system evaporation temperature, condensation temperature, pressure difference correction coefficient, and speed correction coefficient are calculated. Combined with the ten-coefficient power consumption model of the benchmark compressor, the power consumption is predicted using volumetric efficiency, isentropic efficiency, and displacement correction coefficient.

Benefits of technology

It enables accurate power consumption prediction under different compressor types and refrigerant conditions, improves the development efficiency of vehicle thermal management, reduces model development and application costs, supports the rapid development of air conditioning systems for new energy vehicles, and enhances range stability and user experience.
