CAUTION
Charge liquid refrigerant (as opposed to gaseous refrigerant) into the system.
If gaseous refrigerant is charged into the system, the composition of the refrigerant in the cylinder will change and may
result in performance loss.

All the pipes in the figure are liquid pipes.
15.88 : 30 m + 10 m = 40 m
9.52 : 3 m + 1m + 10 m + 10 m + 20 m + 10 m + 10 m = 64 m
6.35 : 10 m
According to the above formula
The calculation result would be 17.08, and it is rounded up to the nearest 0.1.
The final result will be as follows:
Amount of refrigerant to be charged (kg) = (0.2 X 40) + (0.06 X 64) + (0.024 X 10) + 5.0 = 17.08kg
Amount of refrigerant to be charged = 17.1kg
All the pipes in the figure are liquid pipes.
[3/4"] : [98 ft] + [32 ft] = [130 ft]
[3/8"] : [9 ft] + [3 ft] + [32 ft] + [32 ft] + [65 ft] + [32 ft] + [32 ft] = [205 ft]
[1/4"] : [32 ft]
According to the above formula
The calculation result would be 598.07 oz, and it is rounded up to the nearest 1 oz.
The final result will be as follows:
Amount of refrigerant to be charged (oz) = (2.15 X 130) + (0.65 X 205) + (0.26 X 32) + 177 = 598.07oz
Amount of refrigerant to be charged = 599 oz
