Liquid Pipe:
SN A B C D
Diameter of the pipe Φ9.52 Φ9.52 Φ9.52 Φ6.35
Length 30m 10m 5m 5m
SN a b c d
Diameter of the pipe Φ9.52 Φ6.35 Φ6.35 Φ6.35
Length 10m 10m 10m 10m
Total length of liquid pipes:
Φ 9.52: A+B+C+a=30+10+5+10=55m
Φ
6.35: D+b+c+d=5+10+10+10=35m
Notes: if total length is less than 50 meters, there is no need to add extra refrigerant.
So, the minimum required refrigerant amount should be=(55-50)X0.054+35X0.022=1.04kg.
