4.1 Procedure
Step 1: Establish design condions
Step 2: Select indoor units
Step 3: Select outdoor unit
Decide indoor unit safety factor
Determine required total heat load on the outdoor unit
Use the sum of the peak load of each
Is corrected outdoor unit capacity ≥ Required total heat load on outdoor No
Yes
VRF system selecon is complete
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.

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.

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.

Repeat 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 1-5.5), ensuring that the combinaon rao is between 50% and 130%. Refer to Table 1-5.6. As the sum of CIs
of the indoor units is 120. For the 10kW unit is not suitable, try to select 12kW unit.

The number of connected indoor units is 4 and the maximum number of connected indoor units on the 12kW outdoor
unit is 7, 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 12kW outdoor unit is 120, so the combinaon rao is 120
/ 120 = 100%.
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 1-5.8 and 1-5.9.


The corrected capacity 10.84 kW is larger than required total heat load 10.5kW, so selecon is complete.

length: 0m.
2. The heating conditions: indoor temp: 20°CDB (68°F), 15°CWB (44.6°F) outdoor temp: 7°CDB (42.8°F) equivalent pipe length: 5m drop
length: 0m.
3. Sound level: Anechoic chamber conversion value, measured at a point 1 m in front of the unit at a height of *m(1m for 80/105 model, 1.2m
for 120~160 model). During actual operaon, these values are normally somewhat higher as a result of ambient condions.
4. The above data may be changed without noce for future improvement on quality and performance.

Key components:
1. Oil separator:
Separates oil from gas refrigerant pumped out of the compressor and quickly returns it to the compressor. Separaon
eciency is up to 99%.
2. Gas-liquid separator:
Stores liquid refrigerant and oil to protect compressor from liquid hammering.
3. Electronic expansion valve (EXV):
Controls refrigerant ow and reduces refrigerant pressure.
4. Four-way valve(ST1):
Controls refrigerant flow direction. Closed in cooling mode and open in heating mode. When closed, the heat
exchanger funcons as a condenser; when open, the heat exchanger funcons as an evaporator.
5. High and low pressure switches:
Regulate system pressure. When system pressure rises above the upper limit or falls below the lower limit, the high or
low pressure switches turn o, stopping the compressor. Aer 5 minutes, the compressor restarts.
