Additional charge amount R (kg)
= (Lx x 0.022kg/m) + (Ly x 0.061kg/m) + Correction factor of outdoor unit + Correction factor of indoor unit
= (12 x 0.022kg/m) + (28 x 0.061kg/m) + 0 + 0.2 + 0.16 + 0.25 + 0.48
= 3.062
Lx : Real total length of liquid pipe Ø6.35(m)
Ly : Real total length of liquid pipe Ø9.52(m)
