Next, refer to the following table below, calculate the corrective amount of refrigerant according to system
diversity (D)
Corrective amount of refrigerant varies according to the system diversity (D)
Diversity D(%)
Corrective amount
of refrigerant (kg)
50% ≤ D < 60%
60% ≤ D < 70%
70% ≤ D < 80%
80% ≤ D < 90%
90% ≤ D < 95%
95% ≤ D
Lastly, add the corrective amount of refrigerant according to system diversity (D), the corrective amount of
refrigerant according to indoor unit horsepower(C) and the additional amount of refrigerant by the pipe
diameter on liquid side and the pipe length (B) to the compensation amount of refrigerant according to total
outdoor unit horsepower (A)
This is the final additional amount of refrigerant.
If a minus sign is indicated as the result, the additional amount of refrigerant is zero (0) kg, do not reduce the
refrigerant.
