Limitation of the amount of refrigerant to be charged
Sample calculation
Indoor A: ø28.58 40m 1: 50 a: ø6.35
B: ø9.52 10m 2: 250 b: ø9.52
C: 3: 15 c: ø6.35 ø12.70 20m
4: 20 d: ø6.35 D:
5: 140 e: ø9.52
ø9.52 5m
6: 200
The total length of each liquid line is as follows:
ø28.58: A = 40 m
ø22.20: F + G = 4 m
ø12.70: C = 20 m
ø9.52: B + D + E + b + e + f = 35 m
ø6.35: a + c + d = 25 m
Therefore,
<Calculation example>
Additional refrigerant charge
= 40 × 0.33 + 4 × 0.21 + 20 × 0.11 + 35 × 0.054 + 25 × 0.021 + 3
+ 2 + 2 + 6
= 31.7 (31.655) kg
