Piping length: 164ft (50m); Height difference between indoor unit and outdoor unit: 98.4ft (30m)
2.2 Indoor unit selection
Select the suitable capacity for the following conditions: ‘Indoor 20°C(68°F) WB, Outdoor 35°C(95°F) DB’ using
indoor unit capacity table. The selected result is as follows. (Assuming the indoor unit type is duct)

2.3 Outdoor unit selection
1) Assume the indoor unit and outdoor unit combination as follows
 Calculate the total nominal capacity of indoor units in the combination according to the above table:
2.2 × 1 +2.8 × 1+ 3.6 × 1 +4.5 × 1+ 5.6 × 1 + 7.1 × 1 = 25.8kW (88000Btu/h)
 Select outdoor unit: MDV-280(10)W/D2DN1(B) which has nominal cooling capacity: 28kW (95500Btu/h).
 Calculate the proportion: 258/280= 92%
2) Result: Because the proportion is within 50～130%, it is a suitable selection.
Real function data with indoor unit combination
 For the 92% combination, calculate the cooling capacity of outdoor unit MDV-280(10)W/D2DN1(B):
26.8kW(91440Btu/h)←90% (Indoor temperature: WB 20°C(68°F), Outdoor temperature: DB 35°C(95°F))
28.3kW(96560Btu/h)←100% (Indoor temperature: WB 20°C(68°F), Outdoor temperature: DB 35°C(95°F))
