Piping length is considered the distance from the outdoor unit to
the farthest indoor unit.

# Action
1 Determine the connection ratio:
▪ Total outdoor unit capacity class = 500
▪ Total indoor unit capacity class = 550
=> CR≥100%
2 Determine parameter C:
▪ N=5
▪ 8HP: N≥4 => C1=N×0.1=5×0.1kg
▪ 12HP: N<6 => C2=0kg
=> C=C1+C2=0.5kg
