(7) Actual Capacity
In the example, the total indoor unit capacity is 210MBH
(= 24MBH + 24MBH + 30MBH + 36MBH + 48MBH + 48MBH),
and outdoor unit capacity is 192MBH.
Therefore, the connected indoor unit capacity ratio is about 110%.
a) Actual Capacity of Outdoor Unit
Maximum Actual Capacity of Outdoor Unit
= 1 Outdoor Unit Capacity According to Temperature Condition and Connected IDU Capacity Ratio
× 2 Correction Factor According to Piping Length and Lift
×
3
Correction Factor According to Defrosting Operation (only heating)
× 4 Correction Factor According to Altitude
Maximum Actual Capacity of Outdoor Unit
Cooling = 172,000Btu/h × 0.89 × 0.97 = 148,488Btu/h
Heating = 226,000Btu/h × 0.955 × 0.88 × 0.97 = 184,232Btu/h
b) Actual Capacity of Each Indoor Unit
Actual Capacity of Each Indoor Unit
= Actual Capacity of Outdoor Unit × Each Indoor Unit Capacity ÷ Summation of Indoor Units Capacity
