Figure 14-2
The example below illustrates the piping selection procedure
for a system consisting of 1 ODU (16 kW) and 6 IDUs (2.2
kW × 1 + 2.8 kW × 5), as shown in Figure 14-2.
The system's total equivalent piping length for all liquid and
gas pipes is not more than 90 m.
● Select the main pipe (L1) and first branch joint (A)
The ODU capacity is 16 kW, and the equivalent piping length
of all liquid and gas pipes is not greater than 90 m. According
to Table 14-4, the gas and liquid pipe sizes are Φ15.9 and
Φ9.52 respectively. The capacity of the downstream IDUs is
16.2 kW. Then refer to Table 14-6; the main gas/liquid pipe
size is Φ19.1/Φ9.52. Referring to the max value principle,
the gas and liquid pipe sizes are Φ19.1/Φ9.52 and the first
branch joint A is FQZHN-01D.
● Select indoor main pipe (L2 to L5) and branch joint (B to E)
The downstream IDUs of L2 are N1 to N2, with the capacity
of 5.6 kW.
Referring to Table 14-6, the gas and liquid pipe sizes of L2
are Φ12.7 and Φ6.35 respectively, and the branch joint B is
FQZHN-01D.
Similarly, the gas and liquid pipe sizes of L3 are Φ15.9 and
Φ9.52 respectively, the gas and liquid pipe sizes of L4 and
L5 are Φ12.7 and Φ6.35 respectively. The branch joints B to
E are all FQZHN-01D.
● Select the IDU auxiliary pipe (a to f)
The capacity of IDUs N1 to N6 is all less than 6.3 kW.
According to Table 14-7, the gas and liquid pipe size of a to f
are Φ12.7 and Φ6.35 respectively.

Figure 14-3
The example below illustrates the piping selection procedure
for a system consisting of 1 ODU (12 W) and 6 IDUs (5 VRF
IDUs (2.8 kW × 5) and 1 DHW kit (6.0 kW × 1)), as shown in
Figure 14-3. The system's total equivalent piping length for
all liquid and gas pipes is more than 90 m.
● Select the main pipe (L1) and first branch joint (A)
The ODU capacity is 12 kW, and the equivalent piping length
of all liquid and gas pipes is not more than 90 m. According
to Table 14-5, the gas and liquid pipe sizes are Φ19.1 and
Φ9.52 respectively. The downstream IDU capacity is 14.0
kW (The DHW kit capacity does not need to be included).
Then check Table 14-6 to get the main gas/liquid pipe size
of Φ15.9/Φ9.52. According to the maximum value principle,
it shall apply the Φ19.1/Φ9.52, and the first branch joint A
is FQZHN-01D.
● Select indoor main pipe (L2 to L5) and branch joint (B to E)
The downstream IDUs of L2 are N1 to N2, with the capacity
of 5.6 kW. Referring to Table 14-6, the gas and liquid pipe
sizes of L2 are Φ12.7 and Φ6.35 respectively, and the branch
joint B is FQZHN-01D.
Similarly, the gas and liquid pipe sizes of L3 are Φ15.9 and
Φ9.52 respectively, the gas and liquid pipe sizes of L4 are
Φ12.7 and Φ6.35 respectively. The downstream IDUs of
L5 are N5 to N6, with the capacity of 2.8 kW (The DHW kit
capacity does not need to be included). Referring to Table
14-6 and the max value principle, the gas and liquid pipe
sizes of L5 are Φ12.7 and Φ6.35 respectively, and the branch
joint C to E are all FQZHN-01D.
● Select the IDU auxiliary pipe (a to f)
The capacity of IDU N1 to N5 is all less than 6.3 kW.
According to Table 14-7, the gas and liquid pipe sizes of a to
e are Φ12.7 and Φ6.35 respectively.
According to Table 14-7, the gas and liquid pipe sizes of f are
Φ12.7 and Φ6.35 respectively.
