Piping Diameter
for Grouped
Drain Pipes
Select piping diameter from the below table in accordance with the amount of condensation
drained by all units with a common drain pipe.
Consider 2 l/hr of drainage for every 1 HP. For example, drainage from 3 units running at 2 HP
and 2 units running at 3 HP is calculated as follows.
2 (l/hr) × 2 (HP) × 3 (units) + { 2 (l/hr) × 3 (HP) × 2 (units) = 24 l/hr
1. Relationship between horizontal pipe diameter and allowable drainage (for extended ventilation
system)
Note:
Calculations have been made with water area inside the pipe as 10%.
Allowable flow rate figures below the decimal have been discarded.
Use VP30 or larger pipe after the convergence point.
2. Relationship between riser diameter and allowable drainage (for extended ventilation system)
Note:
Allowed flow rate figures below the decimal have been discarded.
Use VP30 or larger pipe in risers.
Use the same drain pipe for the humidifier as the indoor unit.
