This section provides a brief overview of the Compressor Module.
The Compressor Module is comprised of three (3) portions:
• Aerodynamics - The aerodynamics portion manages the compression of refrigerant
through the compressor from suction to discharge comprising centrifugal and IGV
technologies.
• Motor - The motor portion contains a direct-drive, high-efficiency, permanent-magnet
synchronous motor powered by pulse-width-modulating (PWM) voltage supply.
The high-speed variable-frequency operation that affords high-speed efficiency,
compactness and soft start capability. Motor cooling is by liquid refrigerant
injection.
• Electronics - The electronics is divided into two (2) sections: Power electronics
located on the top of the compressor including soft-start, DC-DC, SCR, capacitors
and inverter. Control electronics located on the side of the compressor including:
backplane, BMCC, serial driver and PWM.
