Modeling on the performanc eof an inverter driven scroll compressor

摘要

Thermodynmaci modeling of low-pressure scroll ocmpressor was devleoepd by combining continuity with energy conservation equation.Suctin gas heating was considered using energy balance inside the low pressure shell.Pressure ,temperature and mass of refrigerant-22 as a function of orbiting angle were calculated by solving the governign equations using fourth order Runge-Kutta scheme.Motor efficiency as a funciton of frequency was estimated using experimental results.The develoepd model was appleid to an inverter driven scroll compressor with a variation of frequencies and major operating prameters.To confirm validity of the model,simulation results were ocmpared with expeirmental results at the same operating conditions.
