Some HP29 units utilize a scroll compressor. The scroll
compressor design is simple, efficient and requires few
moving parts. A cutaway diagram of the scroll compressor is
shown in figure 8. The scrolls are located in the top of the
compressor can and the motor is located just below. The oil
level is immediately below the motor.
FIGURE 8
SCROLL COMPRESSOR
DISCHARGE
SUCTION
The scroll is a simple compression concept centered around
the unique spiral shape of the scroll and its inherent properties.
Two identical scrolls are mated together forming concentric
spiral shapes. One scroll remains stationary, while the other is
allowed to "orbit." The orbiting scroll does not rotate or turn but
merely orbits the stationary scroll. Due to its efficiency, the
scroll compressor is capable of drawing a much deeper
vacuum than reciprocating compressors. Deep vacuum
operation can cause internal fusite arcing resulting in
damaged internal parts and will result in compressor
failure. Never use a scroll compressor for evacuating or
for deep vacuum operation (operating compressor at 0
psig or lower) on the system. Table 7 shows the
specifications of scroll compressors used in the HP29
series units.

TABLE 7
Three-Phase Compressor Rotation
Three-phase scroll compressors must be phased
sequentially to ensure correct compressor rotation and
operation. At compressor start-up, a rise in discharge and
drop in suction pressures indicates proper compressor
phasing and operation. If discharge and suction pressures
do not perform normally, follow the steps below to correctly
phase the unit.
1 − Disconnect power to the unit.
2 − Reverse any two field power leads to the unit.
3 − Reapply power to the unit.
Discharge and suction pressures should operate within
their normal start-up ranges.
NOTE − Compressor noise level may be significantly higher
when phasing is incorrect and the unit will not provide
cooling when compressor is operating backwards.
Continued backward operation will cause the compressor
to cycle on internal protector.
