The coefficient of capacity change
2) Calculation of actual system capacity
① Outdoor unit rated capacity
Qodu(rated) [from specification table]
② Outdoor unit capacity at Ti, To temperature.
Qodu(Ti, To) [from capacity table]
③ Outdoor unit capacity coefficient factor
F(Ti, To) = Qodu(Ti, To) / Qodu(rated)
④ Piping correction factor [from capacity coefficient factor table]
Fmain (length, elevation) for main piping length or elevation
Fbranch (length, elevation) for branch piping length or elevation
⑤ Individual indoor unit combinational capacity
Qidu (combi) = Qodu(rated) x Qidu(rated) / Qidu(rated-total)
⑥ Individual indoor unit actual capacity
Qidu (actual) = Qodu(combi) x F(Ti, To) x Fmain (length, elevation) x Fbranch (length, elevation)
Example) • Outdoor unit model : AUUH368D[UU37 UED]
• Indoor units(ATNH36GNLED) : 10kW
• Outdoor temperature : 32.0°CDB
• Indoor temperature: 19.0°CWB
• Main piping length(O/D to BD) : 30m
• Indoor unit actual cooling capacity
- Qodu(rated) : 10.0 kW
- Qodu(Ti, To) : 10.3 kW
- F(Ti, To) : 103%
- Fmain(length, elevation) = 97.4%(by table)
- Qidu(actual) =10.0kW x 1.03 x 0.974 = 10.03kW
