Compressor
Copeland Scrollt Compressor
D
Compressor features high
efficiency with uniform suction
flow, constant discharge flow
and high volumetric efficiency
and quiet operation.
Compressor consists of two
involute spiral scrolls matched
together to generate a series of
crescent shaped gas pockets
between them.
During compression, one scroll
remains stationary while the
other scroll orbits around it.
Gas is drawn into the outer
pocket, the pocket is sealed as
the scroll rotates.
As the spiral movement
continues, gas pockets are pushed to the center of the
scrolls. Volume between the pockets is simultaneously
reduced.
When pocket reaches the center, gas is now at high
pressure and is forced out of a port located in the center of
the fixed scrolls.
During compression, several pockets are compressed
simultaneously resulting in a smooth continuous
compression cycle.
Continuous flank contact, maintained by centrifugal force,
minimizes gas leakage and maximizes efficiency.
Scroll compressor is tolerant to the effects of slugging and
contaminants. If this occurs, scrolls separate, allowing
liquid or contaminants to to be worked toward the center
and discharged.
Low gas pulses during compression reduces operational
sound levels.
Compressor motor is internally protected from excessive
current and temperature.
Compressor is installed in the unit on resilient rubber
mounts for vibration free operation.
Compressor Crankcase Heater
Protects against refrigerant migration that can occur
during low ambient operation.
OPTIONS
Compressor Low Ambient Cut−Off
Non-adjustable switch (low ambient cut-out) prevents
compressor operation when outdoor temperature is
below 35°F.
Compressor Sound Cover
A reinforced vinyl compressor cover containing a 1−1/2
inch thick batt of fiberglass insulation.
All open edges are sealed with a one−inch wide hook and
loop fastening tape.
Compressor Timed−Off Control
Kit prevents compressor short−cycling and allows time for
suction and discharge pressure to equalize.
Permits compressor start−up in an unloaded condition.
Automatic reset with 5 minute delay between compressor
shut−off and start−up.

CONTROLS
OPTIONS
L Connection® Network
See L Connection Engineering Handbook Bulletin in
Controls section for details.
Low Ambient Control
Air conditioners operate satisfactorily down to 45°F
outdoor air temperature without any additional controls.
The Low Ambient Control Kit allows unit operation down
to 30°F.
Freezestat should be installed on compressors equipped
with a low ambient kit.
A compressor lock−out thermostat should be added to
terminate compressor operation below recommended
operation conditions.
Freezestat
Installs on or near the vapor line of the indoor coil or on the
suction line.
Senses suction line temperature and cycles the
compressor off when suction line temperature falls below
it’s setpoint.
Opens at 29°F and closes at 58°F.
Time Delay Relay Kit
Delays the indoor blower−off time during the cooling cycle.
