How to Calculate the Quantity of Adding Refrigerant
Outer diameter of
liquid refrigerant pipe
Quantity of adding
refrigerant per metre
6.35mm
50g/m
9.52mm
80g/m
12.70mm
120g/m
12.70mm(Type E)
140g/m
i.e. 3 indoor units (T

3200W 2000W 2000W
7200W
4000W
❋ Quantity of adding refrigerant
= (Length of ø9.52 liquid pipe x 80g/m) + (Length of ø6.35 liquid pipe x 50g/m) - 500g
= (25m x 80g/m) + (15m x 50g/m) - 500g
= 2250g

◆
Quantity of adding refrigerant =
Total length of piping x quantity of adding refrigerant per metre - 500g
◆
Arrangement : Outer diameter of liquid refrigerant pipe - outer diameter of
gas refrigerant pipe - length of piping

❋ Quantity of adding refrigerant
=
(Length of ø9.52 liquid pipe x 80g/m) + (Length of ø6.35 liquid pipe x 50g/m) - 1000g
= (30m x 80g/m) + (10m x 50g/m) - 1000g
= 1900g
◆
Quantity of adding refrigerant =
Total length of piping x quantity of adding refrigerant per metre - standard quantity(1000g)
◆
Arrangement : Outer diameter of liquid refrigerant pipe - outer diameter of
gas refrigerant pipe - length of piping
