Select the indoor auxiliary connection pipe a to k
The capacity of indoor units N1 to N9 is larger than
5.6kW, so the indoor auxiliary connection pipe a to i
is Φ15.9/Φ9.52.
The capacity of indoor units N10 to N11 is equal or
less than 5.6kW, so the indoor auxiliary connection
pipe j to k isΦ12.7/Φ6.35.
Select main pipe (L1) and first indoor branch A
The system's equivalent length of all liquid pipes is
less than 90m, and the total capacity of the outdoor
units is 32HP. Main pipe L1 is Φ31.8/Φ19.1, first
Indoor branch A is SDV4-HN03k.
Arrangement and layout of
multiple outdoor units
The piping between the outdoor units must be level
and lower than the outdoor unit piping connection.
