If the total refrigerant pipe length (liquid pipe) is smaller than that listed in the table below, no
additional refrigerant will be charged.

Note: if the total refrigerant pipe length is larger than that listed in the table above, the additional
refrigerant for the extra length of the pipe needs to be charged as per 22g/m.

The total length of each liquid refrigerant pipe is: e+d+c+b+a=20+20+15+5+5=65m. Thus, the
minimum additional refrigerant charge
=
(65-50)
×
0.022=0.33kg (Note: no additional refrigerant is
needed for the liquid pipe within 50m).
