Abstract

This paper presents the development and validation of a simulation model of an injection scroll compressor that can be used for optimization of a heat pump system for electric vehicles. The modeling considered the effects of refrigerant leakage and suction gas heating. The simulation model solved continuity and energy conservation equations using 4th Runge-Kutta scheme to predict the pressure and temperature variations according to scroll revolution. The refrigerant mass flow rate, compressor discharge temperature, and compressor power input were calculated. The results of the simulation model were validated with the experimental data. The simulation model predicted the compressor performance within ±10% deviation.
