18 Selection Procedure
Then calculate the outdoor capacity in 92% combination index: 26.8+{(28.3-26.8)/10}×2=27.1kW;
Capacity modification coefficient with pipe length 50m(164ft) and height difference 30m: 0.958
Each indoor unit cooling capacity
Room A:
MDV-D22T2 (27.1×22/258×0.958=2.21kW)
Room B:
MDV-D28T2 (27.1×28/258×0.958=2.82kW)
Room C:
MDV-D36T2 (27.1×36/258×0.958=3.62kW)
Room D:
MDV-D45T2 (27.1×45/258×0.958=4.53kW)
Room E:
MDV-D56T2 (27.1×56/258×0.958=5.64kW)
Room F:
MDV-D71T2 (27.1×71/258×0.958=7.14kW)

2.4 Conclusion
Generally, this result is acceptable, therefore the calculation process has been completed. But if it appears that
the result is not acceptable, the above process may be repeated.
Remark: In this sample, other capacity modification indexes were not considered and are assumed as 1.0.
For more details about the effect factor such as outside ambient/inside ambient DB/WD, please refer to the
performance table of indoor and outdoor units.
