c) Find the correction factor for piping length and level difference ("K1")
Figure 1-5.3: Mini 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 MV8M-120WV2RN1 ("C") by using K1:
 The corrected capacity 10.99kW is larger than required total heat load 10.5kW, 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.)
C = B × K1 = 11.1 × 0.99= 10.99kW
