This paper presents a practical method of calculating hermetic scroll compressor performance, considering mechanical fiction losses leakage loss and heat exchange in the compressor shell. Mechanical friction losses due to fluid resistance of moving parts in the compressor, such as the balancing weight and the orbiting scroll, are considered and estimated. Heat exchange of the refrigerant gas between compressor components is calculated using a simplified thermal analysis model.
The results of these calculations are compared with some measured data. The calculated adiabatic efficiencies agree with the measured values within 3% error, and the calculated discharge gas temperatures agree with the measured va1ues within 3K error, in the revolutionary range from 20 Hz to 150 Hz.
