(b) Total length of distribution tubing (ø9.52)
(c) Total length of distribution tubing (ø6.35)
Refrigerant charge per 1 m of actual length = 40 g/m (25 - 60 type)
Refrigerant charge per 1 m of actual length = 40 g/m
Refrigerant charge per 1 m of actual length = 20 g/m
Additional refrigerant amount (g) = Additional refrigerant for main tubing (g) + Additional refrigerant for distribution tubing (g)

Example
Sample tubing lengths
Find the liquid tube size from Table 1-3.
The amount of additional on-site refrigerant charge is found
by subtracting the outdoor unit charge-less refrigerant
amount from the total charge amount for all tube size.
(48 type)
(Total type capacity of indoor unit 24)
(Total type capacity of indoor unit 24)
The amount of additional on-site refrigerant charge is 1,300 g.
For type 18, the additional refrigerant charge for tubing length (d) of 30 to 40 m is the following:
Additional refrigerant amount (g) = 20X (d) – 600
