4. The calculation method of additional refrigerant oil and refrigerant charging
amount after prolonging connection pipe
After the length of connection pipe is prolonged for 10 m at the basis of standard
length, you should add 5ml of refrigerant oil for each additional 5 m 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.
Note: The information on the additional quantity of coolant is recommended and is
not mandatory.
