Charging additional refrigerant
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 9.52)=40m(131.23'), b+c+d(Ø 9.52)=15m(49.21'), e+f+g(Ø 6.35)=15m(49.21')
The amount of additional refrigerant = 55m(180.45') x 60g + 15m(49.21') x 20g = 3600g
2) The amount of additional refrigerant for each indoor unit
