• Compensated capacity of outdoor units
1. Find (TCout)r.
Refer to the value marked blue in
the value marked orange in
2. Find the following compensation coefficient.
Refer to "Capacity compensation coefficient"
– Compensation coefficient of pipe length
– Compensation coefficient of frosting/defrosting (For heating calculation only)
3. Calculate ∑(TCin)r.
4. Calculate the ratio of ∑(TCin)r to (TCout)r.
Refer to "Cooling capacity range of connectable indoor units"
whether satisfy the condition.
5. Find (TCout)d using the value of previous step and
page 02-54 or
6. Calculate (TCout)c.
– Cooling calculation
(TCout)c = (TCout)d × compensation coefficient of pipe length
– Heating calculation
(TCout)c = (TCout)d × compensation coefficient of pipe length × compensation coefficient
of defrosting/frosting
• System capacity
1. Calculate ∑(TCin)d.
2. System capacity is the smaller value of (TCout)c and ∑(TCin)d.
• Actual capacity of each indoor unit
Calculate actual capacity of each indoor unit by dividing system capacity proportionally.
Actual capacity of indoor unit = (System capacity) × (TCin)r/∑(TCin)r
