5. Equivalent Pipe length conversion
Equivalent pipe length means converting pipe elbow to straight pipe length after
considerate the pressure loss.
Bend and Oil Loop Conversion tablet
Equivalent Pipe length L=Actual Pipe length L+ Bend Qty× Equivalent pipe bend length+
Oil Loop Qty × Equivalent Oil Loop length
Sample:
ALCA-H42/5 Actual Pipe length is 25 meters, Gas pipe diameter is 15.88mm. If there’s 5
bends and 2 oil loops during the installation, then the equivalent pipe length should be:
L=25+0.25×5+2.0×2=30.25(m)
Note:
If there is relatively level difference of indoor and outdoor unit, S-shaped oil trap must be
installed every 8~10m for vertical pipe.
