Long Line Set Applications
/RQJOLQHVHWDSSOLFDWLRQVDUHGHÀQHGDVDSSOLFDWLRQV
that require accessories or alternate construction
methods. The following are special considerations
that need to be addressed when installing a long line
set application:
• Additional refrigerant charge
• Fitting losses and maximum equivalent length
considerations
• Refrigerant migration during the off cycle
• Oil return to the compressor
• Capacity
losses
• System oil level adjustment
Table 2 is used to determine if the application is
considered to have a long line set.
The region of
the chart that is shaded grey is considered to be
a long line set application.
Oil Level Adjustments for Long
Line Set Applications
Additional oil will need to be added for long line set
applications. (Ref. Table 2). Below is the equation for
the oil level adjustment and the compressor name
plate oil charge for the different OD units.
Oil to be Added = [(Charge Adju OD Unit
Name Plate Charge (oz.)) × (0.022) – [(0.10) ×
(Compressor Name Plate Oil Charge (oz.))]
Example: An application requires 125ft of line set
with a liquid line diameter of 3/8”, Charge Adjustment
= 52.4 oz., Name Plate Charge = 107 oz., Name
Plate Oil Charge = 25 oz., Oil to be Added = ((52.4
