<Formula for Calculating Additional Refrigerant Amount>

Do not remove the refrigerant even if the additional refrigerant amount becomes minus result as a result of calculations by the following formula and operate the air conditioner as it is.

Additional refrigerant amount (kg) = Main piping additional refrigerant amount (kg)

+ Branch piping additional refrigerant amount (kg) = {α × (L – 28)} + {γ × (a + b + c – 6)}

α: Additional refrigerant amount per meter of actual main piping length (kg)

γ: Additional refrigerant amount per meter of actual branch piping length (kg)

L : Actual length of main piping (m)

a, b, c : Actual length of branch piping (m)
