Configuration Of Connection Pipe - Toyotomi TRN-828ZR User Manual

Configuration of connection pipe

1. Standard length of connection pipe: 5m, 7.5m, 8m.
2. Min. length of connection pipe is 3m.
3. Max. length of connection pipe
Cooling capacity
5000Btu/h (1465W)
7000Btu/h (2051W)
9000Btu/h (2637W)
12000Btu/h (3516W)
18000Btu/h (5274W)
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 x 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 the following sheet.
