Selecting additional refrigerant charge
* Basic charge
The basic amount of refrigerant for outdoor unit charged in factory is:
Outdoor unit (Series)
Factory charge(kg)
AEX060EDEHA
1.2
* Charge additional refrigerant according to the total length of the pipe.
Each factory charging values are determined according to basic pipe length as below.
AEX060EDEHA ≤ 5m
When extra pipe length are required, additional charging works must be implemented as describes below.
f
Depends on the total length of the liquid side pipe.
- Air to Water
Additional Charge(g) = {(L1-5)x20}+{(L2-5)x50}
• L1: Total length of liquid pipe Ø 6.35(m)
L2: Total length of liquid pipe Ø 9.52(m)
Refrigerant Charging
* Additional charging amount is determined based on liquid pipe specifications.
Outdoor unit of liquid
ø6.35
ø9.52
Additional charging (g)
20g/m
50g/m
Additional charging amount = (sum of total length (m) of ø9.52) × 50g + (sum of total length (m) of ø6.35) × 20g
Ex) 20m × 50g/m + 20m × 20g/m = 1,400g
NOTE
Refrigerant piping work
