89
Single CAC Outdoor Unit
Standard Inverter
7. Capacity Coefficient Factor
7.1 Rate of change in capacity due to the main piping length
 1 Phase Inverter
 Rate of change in cooling capacity
 Rate of change in heating capacity
 3 Phase Inverter
 Rate of change in cooling capacity
 Rate of change in heating capacity
7.2 Calculation of actual system capacity
1. Outdoor unit standard maximum capacity
Q
max.
[from specification table]
2. Outdoor unit capacity at Ti, To temperature.
Q
(Ti, To)
[from capacity table]
3. Outdoor unit capacity coefficient factor
F
(Ti, To)
= Q
(Ti, To)
/ Q
(max.)
4. Piping correction factor
F
piping
for piping length [from capacity coefficient factor table]
5. Indoor Unit actual capacity
Q
actual
= Q
