This manual is for the application of the Carlyle
®
Com-
pound Cooling 06CC compressor. The operational limits,
required accessories, and operational guidelines are
contained in this manual and must be complied with to
stay within the compressor warranty guidelines.
The Carlyle Compound Cooling compressor offers the
highest energy efficiency available for low temperature
refrigeration when using a single compressor. A single
Carlyle Compound Cooling compressor provides the
capacity and efficiency equal to a two-compressor
booster system.
The Carlyle Compound Cooling compressor is designed
with two compression stages in a single body and utilizes
subcooling from a simple plate to plate heat exchanger
that is the system subcooler. Figure 1 shows a simple
single compressor system.
Features and Benefits
•
Very high capacities and efficiencies when compared
to a single-stage, low-temperature compressor
•
Very low compression ratios for low temperature
refrigeration
•
Two-stage booster performance in a single-compres-
sor body
•
Subcooling allows for smaller system refrigerant lines
and therefore a smaller refrigerant charge
•
Simple application of subcooling
•
Eliminates compressor short cycling as capacity
remains stable over a wide range of head pressures
•
Can be used with R-22, R-404A, R-407A, and R-507
•
No separate subcooling rack or compressor needed
How Compound Cooling Works
A variation of the two-stage booster system, the internally
compounded compressor has both the high and low
stages built into one compressor body. In this arrange-
ment, compression is accomplished in two stages, safely
and economically.
All eight 06CC models have six cylinders. Four cylinders
act as the low stage and “boost” the suction pressure
from the refrigeration load to the intermediate pressure.
The remaining two cylinders, acting as the high stage,
complete the compression to normal condensing temper-
atures. The result is lower internal losses and a compres-
sor that delivers more capacity in the same displacement.
The lower losses increase operating efficiencies. See
Fig. 1, Single Compressor System diagram, for review of
system operation.
Obsolete Compressors
Model 06CC016, 06CC018, and 06CC124 compound
compressors are not manufactured at this time. Informa-
tion on these sizes is included in this manual as a refer-
ence for existing systems.
