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):
Additional refrigerant charging amount = prolonged length of liquid pipe ×
additional refrigerant charging amount per meter
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 Sheet 2.
