Construction
D The electric inverter compressor consists of a spirally wound fixed scroll and variable scroll that form
a pair, a brushless motor, an oil separator, a motor shaft and A/C inverter.
D The fixed scroll is integrated with the housing. Because the rotation of the shaft causes the variable scroll
to revolve while maintaining the same posture, the volume of the space that is partitioned by both scrolls
varies to perform the suction, compression, and the discharge of the refrigerant gas.
D Locating the suction port directly above the scrolls enables direct suction, thus realizing improved
suction efficiency.
D Containing a built-in oil separator, this compressor is able to separate the compressor oil that is
intermixed with the refrigerant and circulates in the refrigeration cycle, thus realizing a reduction in the
oil circulation rate.
D This inverter converts the HV battery's nominal voltage of DC 244.8 V into AC and supplies power to
operate the compressor.
