6 Selection Procedure
6.1 Procedure
Step 1: Establish design conditions
Step 2: Select indoor units
Step 3: Select outdoor units
Notes:
1. If the indoor design temperature falls between two temperatures listed in the indoor unit's capacity table, calculate the corrected capacity by interpolation.
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, interpolating where necessary. For the indoor unit capacity tables, refer to the indoor unit technical
manuals.
Yes
Design temperature and humidity (indoor and outdoor)
Required heat load of each room
System peak load
Piping length, level differences
Indoor unit specifications (type and quantity)
Decide indoor unit safety factor
Select indoor unit models ensuring that:
Indoor unit capacity corrected for indoor air temperature WB1 ≥ Required heat load × Indoor unit safety factor
Determine required total heat load on outdoor units
Use the sum of the peak load of each room Use the system peak load
P
rovisionally select outdoor unit capacity based on combination ratio
limitations
Confirm that the number of indoor units connected to the outdoor units is within limitation
Correct cooling and heating capacities of the outdoor units for the following items:
Outdoor air temperature / Indoor air temperature WB / Combination ratio / Piping length, level
difference / Piping heat loss / Frost accumulation (for heating capacity only)
Is corrected outdoor unit capacity ≥ Required total heat load on outdoor units?
VRF system selection is complete
No

Step 1: Establish design conditions
Indoor air temperature 25°C DB, 18°C WB; outdoor air temperature 33°C DB.
Determine peak load of each room and system peak load. As shown in Table 1-6.1, the system peak load is 50.7kW.

The maximum piping lengths and level differences in this example are as given in Figure 1-6.2.

Indoor unit type for all rooms: Medium Static Pressure Duct (CNT2).
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 static 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 1-6.3.

Step 3: Select outdoor units
Determine the required total heat load from the indoor units to the outdoor units 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 50.7kW.
Provisionally select outdoor units using the sum of the capacity indexes (CIs) of the selected indoor units (as shown in
Table 1-6.4), ensuring that the combination ratio is between 50% and 130%. Refer to Table 1-6.5. As the sum of CIs of
the indoor units is 706, outdoor units from 20HP to 50HP are potentially suitable. Start from the smallest, which is the
20HP unit.

The number of connected indoor units is 8 and the maximum number of connected indoor units on the 20HP outdoor
unit is 33, so the number of connected indoor units is within the limitation.
Calculate the corrected capacity of the outdoor units:
a) The sum of the indoor unit CIs is 706 and the CI of the 20HP outdoor unit (MV6-XMi 560T) is 560, so the
combination ratio is 706 / 560 = 126%.
b) Using the outdoor units’ cooling capacity table, interpolate to obtain the capacity (“B”) corrected for outdoor air
temperature, indoor air temperature, and combination ratio. Refer to Tables 1-6.6 and 1-6.7.

c) Find the correction factor for piping length and level difference (“K1”)
Figure 1-6.3: V6 rate of change in cooling capacity
Notes:
1. The horizontal axis shows equivalent length of piping between farthest indoor unit and
first outdoor branch joint; the vertical axis shows the largest level difference between
indoor unit and outdoor unit. For level differences, positive values indicate that the
outdoor unit is above the indoor unit, negative values indicate that the outdoor unit is
below the indoor unit.
d) Calculate the corrected capacity of MV6-XMi 560T (“C”) by using K1:
C = B × K1 = 60 × 0.898 = 53.8kW
The corrected capacity 53.8kW is larger than required total heat load 50.7kW, so selection is complete. (In the event
that the corrected capacity is lower than the required total heat load, Step 3 should be repeated from the point
where the outdoor unit capacity is provisionally selected.)
