6-3-4 Selection example based on cooling load
The unit size for room A has to be increased from 25 to 32 because the capacity is less than the load. For new combination, actual capacity is calculated
as follows.
•Indoor unit combination total capacity index
25x2 + 31.25 + 40x5 + 50 + 62.5 + 80 + 100x2 = 673.75 (103.65 %)
Outdoor unit cooling capacity:
76.44kW (direct interpolation between 100 % and 110 % in the table)
•Individual capacity
Capacity of FXYCP25K = 76.44 x
25
= 2.84kW
673.75
Capacity of FXYCP32K = 76.44 x
32
= 3.63kW
673.75
Capacity of FXYCP40K = 76.44 x
40
= 4.54kW
673.75
Capacity of FXYSP50K = 76.44 x
50
= 5.67kW
673.75
Capacity of FXYSP63K = 76.44 x
63
= 7.15kW
673.75
Capacity of FXYMP80K = 76.44 x
80
= 9.08kW
673.75
Capacity of FXYFP100K = 76.44 x
100
= 11.35kW
673.75
Actual capacity of new combination
Then, the capacities have to be corrected for actual piping length according to the location of indoor and outdoor units and the distance between them.
NOTE
Select the optimum size of units and take care no to select the oversized units.
