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.
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)
CAUTION
1. Be certain to write the additional refrigerant amount, pipe length (actual length), head
and other specification on the nameplate put on the outdoor unit for recording.
2. Seal the correct amount of additional refrigerant in the system.
Additional refrigerant amount (kg) = Main piping additional refrigerant amount (kg) +
Branch piping additional refrigerant amount (kg)
= {
α
× (L – 28)} + {
γ
× (a + b + c – 6)}
