First orbit; SUCTION gas enters at the perimeter of the scroll elements and is
sealed as the scrolls rotate approximately one revolution.
Second orbit; During the COMPRESSION process, the gas is further compressed towards the center of the scroll elements to an intermediate
pressure.
Third orbit; In the DISCHARGE orbit, the gas is further compressed to
discharge pressure and then exits at the center through the discharge port.
With a three step simultaneous process of suction, compression and
discharge and two gas pockets in each step that are 180 degrees apart, the
compression process is balanced and very smooth, resulting in high efficiency,
low sound/vibration and excellent reliability.
- Sound sources are minimized – The SANYO scroll has a fixed
eccentric offset, completely eliminating scroll contact in the radial
direction, and the noise generated from radial scroll contact. Axial
sealing is accomplished with PPS resin tip seals that are
significantly quieter than the cast iron used on other scrolls. - Transmission through the shell is significantly reduced – With
thicker center shell, structural discharge baffle, optimized top shell
design and heavy duty seam and location welds. - The resulting overall sound level is 5-8 dB(A) lower than the
competition on a weighted average basis.
- Initial compressor design from Japan, supported by Abusive
Reliability Testing at Dalian to monitor factory process. - Rigorous customer application approval process assures reliable
system designs. - First year reliability < 0.08%
