Part 1 - General Information
c) Find the correction factor for piping length and level difference (“K1”)
Figure 1-6.3: VC 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 MVC-560WV2GN1 (“C”) by using K1:
C = B × K1 = 59.95 × 0.898 = 53.8kW
 The corrected capacity 53.8kW is larger than required total heat load 50.7kW, 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.)
