1. Standard length of connection pipe
● 5m, 7.5m, 8m.
4. The additional refrigerant oil and refrigerant charging required after prolonging
connection pipe
●
After the length of connection pipe is prolonged for 10m at the basis of
standard length, you should add 5ml of refrigerant oil for each additional 5m
of connection pipe.
●
The calculation
m
ethod of additional refrigerant charging
am
ount (on the
b
asis
of liquid pipe):
●
Basing on the length of standard pipe, add refrigerant according to the
requirement as shown in the table.
The additional refrigerant charging amount
per meter is di
f
ferent according to the diameter of liquid pipe. See the
following sheet.
