Conrm that the number of indoor units connected to the outdoor unit is within
Correct cooling and heang capacies of the outdoor unit for the following items:
Outdoor air temperature / Indoor air temperature WB / Combinaon rao / Piping length, level dierence
/ Piping heat loss / Frost accumulaon (for heang capacity only)
Provisionally select outdoor unit capacity based on combinaon rao limitaons
Use the system peak
Select indoor unit models ensuring that:
Indoor unit capacity corrected for indoor air temperature WB1 ≥ Required heat load × Indoor unit safety factor
Design temperature and humidity (indoor and outdoor)
Required heat load of each room
System peak load
Piping length, level dierences
Indoor unit specicaons (type and quanty)
Notes:
1. If the indoor design temperature falls between two temperatures listed in the indoor unit’s capacity table, calculate the corrected capacity by interpolaon.
If the indoor unit selection is to be based on total heat load and sensible heat load, select indoor units which satisfy not only the total heat load
requirements of each room but also the sensible heat load requirements of each room. As with total heat capacity, the sensible heat capacity of indoor units
should be corrected for indoor temperature, interpolang where necessary. For the indoor unit capacity tables, refer to the indoor unit technical manuals.

Indoor unit type for all rooms: Medium Stac Pressure Duct (T2).
Step 2: Select indoor units

In this example, a safety factor is not used (i.e. the safety factor is 1).

Select indoor unit models using the medium stac pressure duct cooling capacity table. Each indoor unit’s corrected
capacity needs to be greater than or equal to the peak load of the relevant room. The selected indoor units are shown
in Table 1-5.3.

Step 3: Select outdoor unit

Determine the required total heat load from the indoor units to the outdoor unit based on either the sum of the
peak loads of each room or the system peak load. In this example, it is determined based on the system peak load.
Therefore, the required heat load is 10.5kW.

Provisionally select an outdoor unit using the sum of the capacity indexes (CIs) of the selected indoor units (as shown
in Table 1-5.4), ensuring that the combinaon rao is between 50% and 130%. Refer to Table 1-5.5. As the sum of CIs
of the indoor units is 120, all outdoor units are potenally suitable except 8kW. Start from the smaller, which is the
10kW unit.


The number of connected indoor units is 4 and the maximum number of connected indoor units on the 10kW outdoor
unit is 6, so the number of connected indoor units is within the limitaon.

Calculate the corrected capacity of the outdoor unit:
a) The sum of the indoor unit CIs is 120 and the CI of the 10kW outdoor unit is 100, so the combinaon rao is 120
/ 100 = 120%.
b) Using the outdoor unit’s cooling capacity table, interpolate to obtain the capacity (“B”) corrected for outdoor air
temperature, indoor air temperature, and combinaon rao. Refer to Tables 1-5.6 and 1-5.7.

c) Find the correcon factor for piping length and level dierence (“K1”)
Figure 1-5.3: Mini rate of change in cooling capacity
d) Calculate the corrected capacity of KMF-100 DVN4 (“C”) by using K1:
C = B × K1 = 10.4 × 0.968 =10.07kW

The corrected capacity 10.07 kW is lower than required total heat load 10.5kW, so selecon is not complete. Step 3
should be repeated from the point where the outdoor unit capacity is provisionally selected.
