1) Amount of additional refrigerant depending on the pipe size(X)
Total length of each liquid pipe: Φ9.52
:
A+B+C+D+a+b+c+d=10+5+4+5+3+3+2+1=33m
2) Amount of additional refrigerant depending on Quantity of IDU(Y)
Quantity of indoor unit: 4 sets
3) Amount of additional refrigerant depending on certain model of IDU(Z)
IDU includes GMV-NDR40PH/B1-T
Therefore, the total charging amount
=
(33×0.054)+(4-2)×0.3+0.5x4
=
4.382kg
