Suction Line Selection
Purpose of the suction line is to return superheated
vapor to the condensing unit from the evaporator�
Proper suction line sizing is important because it
plays an important role in returning oil to the com-
pressor to prevent potential damage to the bear-
ings, valves, and scroll sets� Also, an improperly
sized suction line can dramatically reduce capacity
and performance of the system� The procedure for
selecting the proper suction line is as follows:
• The total amount of suction line needed
• Add all of the equivalent lengths associated with
any ttings or accessories using the table on
previous page�
• Add the total length and tting pressure drop.
This will equal your total equivalent length�
• Reference Table 2 to verify that the calculated
equivalent length falls within the compatibility
region of the chart�
• Verify Table 3 to verify the capacity dierence is
compatible with the application�
Refrigerant Migration During
Off Cycle
Long line set applications can require a consider-
able amount of additional refrigerant� This addition-
al refrigerant needs to be managed throughout the
entire ambient operating envelope that the system
will go through during its life cycle. O-Cycle mi-
gration is where excess refrigerant condenses and
migrates to the lowest part of the system� Exces-
sive build-up of refrigerant at the compressor will
result in poor reliability and noisy operation during
startup� This section demonstrates the required
accessories and unit conguration for dierent ap-
plications�
