System design recommendations

Essential piping design

considerations

Proper piping practices should be employed to
ensure adequate oil return, even under minimum
load conditions with special consideration given
to the size and slope of the tubing coming
from the evaporator. Tubing returns from the
evaporator should be designed so as not to trap
oil and to prevent oil and refrigerant migration
back to the compressor during off-cycles.

If the evaporator lies above the compressor, the
suction line must have a loop at the evaporator
outlet to prevent refrigerant from draining into
the compressor during off-cycles.

If the evaporator were situated below the
compressor, the suction riser must be trapped so
as to prevent liquid refrigerant from collecting at
the thermal bulb location (see fig. 1).

When the condenser is mounted at a higher
position than the compressor, a suitably sized
«U»-shaped trap close to the compressor is
necessary to prevent oil leaving the compressor

from draining back to the discharge side of the
compressor during off cycle. The upper loop also
helps avoid condensed liquid refrigerant from
draining back to the compressor when stopped
(see fig. 2). The maximum elevation difference
between the indoor and outdoor section cannot
exceed 8 m. System manufacturers should specify
precautions for any applications that exceed
these limits to ensure compressor reliability.

Piping should be designed with adequate three-
dimensional flexibility. It should not be in contact
with the surrounding structure, unless a proper
tubing mount has been installed. This protection
proves necessary to avoid excess vibration, which
can ultimately result in connection or tube failure
due to fatigue or wear from abrasion. Aside from
tubing and connection damage, excess vibration
may be transmitted to the surrounding structure
and generate an unacceptable noise level within
that structure as well (for more information on
noise and vibration, see the section on: "Sound
and vibration management").

General

Successful application of scroll compressors is
dependent on careful selection of the compressor
for the application. If the compressor is not correct

for the system, it will operate beyond the limits
given in this manual. Poor performance, reduced
reliability, or both may result.
