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 indoor units (N1 to N11) downstream of indoor
branch joint A have a total capacity of 80+65.6 =
145.6kW. The system's equivalent length of all liquid
pipes is less than 90m. The total capacity of the
outdoor units is 32 + 20= 52HP. Main pipe L1 is Φ
38.1/Φ19.1. First Indoor branch A is SDV4-HN04k.
Select outdoor connection pipes (g1 and g2) and
outdoor branch (L)
There are two outdoor units in the system. The
master unit is 32HP, the slave unit is 20HP. Outdoor
connection pipes g1 isΦ38.1 / Φ19.1, g2 is Φ31.8 / Φ
15.9. Outdoor branch L is SDV5-HW02N1M.
