Indoor 1: 36 A: ø12.7 [1/2 in] 40 m [131 ft] a: ø9.52 [3/8 in] 10 m [32 ft]
At the
conditions
below: 2: 30 B: ø9.52 [3/8 in] 10 m [32 ft] b: ø9.52 [3/8 in] 5 m [16 ft]
3: 15 C: ø9.52 [3/8 in] 15 m [49 ft] c: ø6.35 [1/4 in] 10 m [32 ft]
4: 12 D: ø9.52 [3/8 in] 10 m [32 ft] d: ø6.35 [1/4 in] 10 m [32 ft]
5: 24 e: ø9.52 [3/8 in] 10 m [32 ft]
The total length of each liquid line is as follows:
ø12.7 [1/2 in]: A = 40 m [131 ft]
ø9.52 [3/8 in]: B + C + D + a + b + e = 10 [32] + 15 [49] + 10 [32] + 10 [32] + 5 [16]
+ 10 [32] = 60 m [193 ft]
ø6.35 [1/4 in]: c + d = 10 [32] + 10 [32] = 20 m [64 ft]
Therefore, additional refrigerant charge
= 40 m [131 ft] × 0.11 kg/m [1.19 oz/ft] + 60 m [193 ft] × 0.054 kg/m [0.59 oz/ft]
+ 20 m [64 ft] × 0.021 kg/m [0.23 oz/ft] + 3.0 kg [106 oz] = 11.1 kg [391 oz]

Indoor 1: 30 A: ø28.58 [1-1/8 in] 40 m [131 ft] a: ø9.52 [3/8 in] 10 m [32 ft]
At the
conditions
below:
2: 96 B: ø9.52 [3/8 in] 10 m [32 ft] b: ø9.52 [3/8 in] 5 m [16 ft]
3: 12 C: ø9.52 [3/8 in] 20 m [64 ft] c: ø6.35 [1/4 in] 5 m [16 ft]

5: 12 E: ø9.52 [3/8 in] 5 m [16 ft] e: ø6.35 [1/4 in] 5 m [16 ft]
6: 24 F: ø22.2 [7/8 in] 3 m [9 ft] f: ø9.52 [3/8 in] 5 m [16 ft]
G: ø19.05 [3/4 in] 1 m [3 ft]
The total length of each liquid line is as follows:
ø28.58 [1-1/8 in]: A = 40 m [131 ft]
ø22.2 [7/8 in]: F = 3 m [9 ft]
ø19.05 [3/4 in]: G = 1 m [3 ft]
ø9.52 [3/8 in]: C + D + E + a + b + f = 50 m [164 ft]
ø6.35 [1/4 in]: c + d + e = 20 m [64 ft]
Therefore, additional refrigerant charge
= 40 m [131 ft] × 0.33 kg/m [3.55 oz/ft] + 3 m [9 ft] × 0.21 kg/m [2.26 oz/ft]
+ 1 [3 ft] × 0.14 kg/m [1.51 oz/ft] + 50 m [164 ft] × 0.054 kg/m [0.59 oz/ft]
+ 20 m [64 ft] × 0.021 kg/m [0.23 oz/ft] + 3.0 kg [106 oz] + 2.0 kg [71 oz]
+ 5.0 kg [177 oz]
= 27.1 kg [956 oz]
