2.8.1.2 Refrigerant Pipe Sizing
Refrigerant lines for split systems must be sized
according to the piping distance between the
evaporator and the condenser. Each valve, fi tting and
bend in the refrigerant line must be considered in this
calculation. Pipe sizes are given for “equivalent feet”,
not linear feet. Do not confuse the terminologies.
For example, a 7/8” standard 90° elbow has an
equivalent length of 1.5 feet; a 7/8” branch Tee has
an equivalent length of 3.5 feet. These corrections
must be accounted for when sizing your piping.
debris to get inside refrigerant lines. Dry nitrogen
should be fl owing through the tubing while soldering
at a rate of not less than 1-2 CFM (0.028-0.57 M 3/
minute).

Note
Refrigerant piping between the CyberRow unit
and the remote condenser must not exceed 150
feet (total equivalent length). The maximum
level drop from the CyberRow unit to the
condenser must not exceed 20 feet.
Note
Consult ASHRAE standards and refer to the
Copeland applications data guide for more
detailed information regarding refrigerant line
traps and line sizing.
Refer to the following table for standard equivalent
lengths, in feet, of straight pipe.
