6-8. Additional Refrigerant Amount

nTwin system

<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 – 18) + γ × (a + b – 4)

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 : Actual length of branch piping (m)

Standard piping length		Connecting pipe diameter			Additional refrigerant amount per Meter (kg/m)
