Summary

We developed an oil circulation rate (OCR) simulation technology with particle motion analysis that can quantitatively evaluate the influence of the shape and structure in the scroll compressors. It became clear that particle moving analysis was good for analyzing oil mist behavior. The analysis consists of three simulations. These simulations have three different injectors that define particles starting positions. The first one is at the discharge port of the fixed scroll, and another is on the oil pool in the bottom of scroll compressor. And the last injector is on the motor top, and these three simulations calculate number of particles that discharge out from the compressor to the cycle unit. The mechanism of the oil mist behavior inside the scroll compressor was clarified, and these simulations made it possible to be calculated mostly within ± 1wt% to the measured OCR in various model’s case.
