113 Installation Procedure
6.3 Example
The example is as blow:
Provided that the capacity of outdoor unit is (16+12+10) HP, the equivalent length of all pipes in this system is
larger than 90m, the pipe length from the 1
st
branch joint to the farthest indoor unit is less than 40m, and the
pipe from indoor unit to the nearest branch joint or direct connected MS is less than 10m.
1. Select indoor unit auxiliary pipes from indoor unit to the nearest branch joint or direct connected MS: b, c, d,
e, f, h, i, l, m, n, p, q, r.
Refer to table 6, the pipes of b, c, e, f, h, i, m, n, p, q and r are Φ 15.9/ Φ 9.53, and the pipes of d and l are
Φ 12.7/ Φ 6.35.
2. Select indoor unit auxiliary pipes between MS and downstream branch joint: a, g, j, k.
Refer to table 5, the pipes of a, g, j and k are
Φ 15.9/ Φ 9.53, the brand pipe assembly
Ⅰ
,
Ⅱ
,
Ⅲ
and
Ⅳ
are
FQZHN-01D.
3. Select indoor unit main pipes: L1~L13
 The downstream indoor units of L3 are N1 and N2, which capacity is 7.1×2=14.2kW. Refer to table 1, the
indoor unit main pipe L3 is Φ 19.1 / Φ 15.9/ Φ 9.53, select MS02/N1-C for MS1.

The downstream indoor unit of L5 is N3, which capacity is 14 kW. Refer to table 1, the indoor unit main pipe
L5 is Φ 19.1 / Φ 15.9/ Φ 9.53, select MS02/N1-C for MS2.
 The downstream indoor unit of L6 is N4, which capacity is 2.8 kW. Refer to table 1, the indoor unit main pipe
L6 is Φ 12.7/ Φ 9.53/ Φ 6.35, select MS02/N1-C for MS3.
 The downstream indoor units of L4 are N3 and N4, which capacity is 14+2.8=16.8 kW. Refer to table 1, the
indoor unit main pipe L4 is Φ 22.2/ Φ 19.1/ Φ 9.53, the branch pipe assembly C is FQZHN-02SB.
 The downstream indoor units of L2 are N1, N2, N3 and N4, which capacity is 7.1×2+14+2.8=31 kW. Refer to
table 1, the indoor unit main pipe L2 is Φ 22.2/ Φ 19.1/ Φ 12.7, the branch pipe assembly B is FQZHN-02SB.
 The downstream indoor unit of L12 is N5, which capacity is 14 kW. Refer to table 1, the indoor unit main pipe
L12 is Φ 19.1/ Φ 15.9 / Φ 9.53, select MS02/N1-C for MS4.

The downstream indoor units of L13 are N6 and N7, which capacity is 7.1×2=14.2 kW. Refer to table 1, the
indoor unit main pipe L13 is Φ 19.1/ Φ 15.9 / Φ 9.53, select MS02/N1-C for MS5.
 The downstream indoor units of L10 are N5, N6 and N7, which capacity is 14+7.1×2=28.2 kW. Refer to table
1, the indoor unit main pipe L10 is Φ 22.2/ Φ 19.1/ Φ 12.7, the branch pipe assembly F is FQZHN-02SB.
