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 method of additional refrigerant charging amount (on the basis
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 different according to the diameter of liquid pipe. See the
following sheet.
