Development of a high efficiency scroll compressor with MS motor.

Author(s) : TOJO K., MIYAKE M, OOTAHARA M., et al.

Summary

With the increase of recent environmental concerns, energy saving is one of the most important issues in the air-conditioning and refrigeration industry. Likewise, in order to improve the annual performance factor of heat-pump air conditioners, capacity modulation by means of motor rotational speed control and multiple fixed speed compressor system are becoming widespread. To meet these demands, the authors developed a new scroll compressor series for packaged air conditioners with revolutionary high efficiency. The scroll compressor has an advanced asymmetric scroll wrap, an optimized axial compliant mechanism and a sophisticated oil feeding system. The newly developed ultra-high efficiency magnetic synchronous (MS) motor is adopted instead of a conventional induction motor. As a result, the motor's energy loss has been reduced by 40%, thus realizing a noticeable improvement in the compressor's efficiency.
