7.7 Confi guration 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 and max. high difference.
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.
● Thecalculation methodof additional refrigerant charging amount (onthe 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 the following sheet.
Additional refrigerant charging amount for R22, R407C, R410A and R134a
