Checklist 2
• Check the additional amount of refrigerant.
Calculate the additional amount of refrigerant from the additional amount of refrigerant (A) by the pipe
diameter on the liquid side, the pipe length to be connected, and the corrective amount of refrigerant (B)
according to system capacity.
First, enter the total length for each liquid pipe diameter in the following table, and then calculate the additional
amount of refrigerant by pipe length.
<(A) : Additional amount of refrigerant by pipe length>
Next, refer to the following table for the corrective amount of refrigerant (B) according to system capacity.
<(B) : Adjustment amount of rifrigerant according to system capacity>
Lastly, add the additional amount of refrigerant by pipe length (A) to the Adjustment amount of according
refrigerant to system capacity (B).
This is the final additional.
