Development of highly efficient compressor series driven by IPM motors.

Author(s) : OBITANI T., OZAWA H., TANIWA H., et al.

Summary

The demand for highly efficient compressors with inverter speed control is escalating as well as those with HFC refrigerants. The authors have developed highly efficient compressor series with inverter speed control consisting of five models (capacity ranging from 2.2 to 16 kW). The Interior Permanent Magnet (IPM) synchronous motors using rare-earth permanent magnets are adopted for all the compressors of this series. Swing compressors are adopted for small range from 2.2 to 8 kW and scroll compressor is adopted for large range up to 16 kW. The efficiency is improved by 17 to 32% in the low speed range and by 12 to 18% in the high speed range. All the models are designed for R410A, R407C and R22.
