4.4.5.5 Compressor Oil Level
Adjustment
Additional oil will need to be added for long line set ap-
plications. Below is the equation for the oil level adjust-
ment. The compressor name plate oil charge for the
different outdoor units is shown in the table below.
Oil to be Added = [(Charge Adju OD Unit
Name Plate Charge (oz.)) × (0.022) – [(0.10) × (Com-
pressor Name Plate Oil Charge (oz.))]
Example:
An application requires 125 ft. of line set
with a liquid line diameter of 5/8”, Charge Adjustment =
52.4 oz., Name Plate Charge = 107 oz., Name Plate Oil
Charge = 25 oz., Oil to be Added = ((52.4 oz. +107 oz.) ×
.022) – (.10 × 25 oz.) = 1.0 oz.
4.4.5.6 Capacity Losses
Long line lengths can result in a reduction in capacity
due to suction line pressure drop and heat gain. Refer
to Table 2 for capacity loss multipliers for various vapor
line diameters and lengths. Only use vapor lines listed in
Table 2 to assure proper oil return. This table does not
account for any capacity loss due to heat gain from the
environment. It is extremely important not to oversize the
suction line to minimize capacity loss at the expense of
proper oil return. The full length of the suction line must
be insulated to minimize heat gain.
