6-3 Selection procedure System based on cooling load
6-3-4 Selection example based on cooling load
1 Given
Design condition
Cooling : indoor 20°CWB, outdoor 33°CDB
Cooling load
Power supply : 3-phase 380V/50Hz
2 Indoor unit selection
Enter indoor unit capacity table at:
20°CWB indoor temperature
33°CDB outdoor air temperature.
Selection results are as follows:
3 Outdoor unit selection
•Assume that the indoor and outdoor unit combination is as follows.
Outdoor unit : RSXYP26K
Indoor unit : FXYCP25K x 3 , FXYCP40K x 5, FXYSP50K x 2, FXYFP80K x 1, FXYMP100K x 2
•Indoor unit combination total capacity index
25 x 3 + 40 x 5 + 50 x 2 + 80 x 1 + 100 x 2 = 655 (100.77 %)
4
Actual performance data (50Hz)
Outdoor unit cooling capacity : 75.78kW (RSXYP26K, 100.77 %)
direct interpolation between 100 and 110 %
