MITSUBISHI ELECTRIC / M/S SERIES
Example of total additional charge calculation
Formula
∆W(g) = [Lenght of pipes (m) -
Precharge lenght (m)] x additional charge (g/m)
Example
Outdoor/indoor unit = MSZ-LN50VG2 / MUZ-LN50VG2
Total pipes lenght (inlet piping only) = 25 m
Lenght with additional charge (as tab) = 7 m
Additional charge = 20 g/m
Calculation: ∆W(g) = [25 - 7] x 20 = 360 g
