The amount of additional refrigerant charging
1) The amount of additional refrigerant depending on the pipe size .
- Amount of additional refrigerant has to be calculated based on the sum of all liquid pipe length .
Size of liquid pipe [mm(inch)]
Additional amount [kg/m (lb/ft)]
Additional refrigerant charging calculation = The sum of total length of Ø 9.52 liquid pipe(m) x 60g + the sum of
Ex) a(Ø 9 . 5 2)=40m(131 . 2 3'), b+c+d(Ø 9 . 5 2)=15m(49 . 2 1'), e+f+g(Ø 6 . 3 5)=15m(49 . 2 1')
The amount of additional refrigerant = 55m(180 . 4 5') x 60g + 15m(49 . 2 1') x 20g = 3600g
2) The amount of additional refrigerant for each indoor unit

MSP duct (AM0✴✴✴FNMDCH/AA)
HSP duct (AM0✴✴✴FNHDCH/AA)
Wall mounted (AM0✴✴✴FNTDCH/AA)
Ceiling (AM0✴✴✴FNCDCH/AA)
Ex) When the indoor unit AM023FN1DCH/AA and AM052FNDNCH/AA are combinated
Additional refrigerant charging = 250g + 450g = 670g
3) The total amount of additional refrigerant charging = the amount of refrigerant charging for pipe + the amount of
refrigerant for each indoor unit .
Ex) The amount of additional refrigerant charging = 3600g + 700g = 4300g
