Capacity coefficient factor (Reference) 5CSL0-06B
3) 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 : AUUW486D[UU48W U3D]
• Total indoor units combination : UT24 + UT24
• Outdoor temperature : 32.0°CDB
• Indoor temperature: 19.0°WDB
• Main piping length(O/D to BD):40m
• Branch piping length(BD to I/D):10m
• Indoor unit actual cooling capacity
- Qodu(rated) : 14.0 kW
- Qodu(Ti, To) : 14.4 kW
- F(Ti, To) : 14.4 / 14.0 = 1.03%
- Fmain (length, elevation) = 91.1%
- Fbranch (length, elevation) = 97.8%
- Qidu(actual) [UT24 + UT24] = 14.0 kW x 1.03 x 0.911 x 0.978 = 12.85kW
