1.05 * The capacity change
rate due to the
refrigerant tubing length
and elevation difference
for each horsepower
level is found from the
correction coefficient
for that horsepower
from this table
multiplied by the base
capacity change rate
from the graphs at left.
However, even if the
calculated result
exceeds 100%, the
maximum capacity
change rate is 100%.
*1 Sample calculations
(System: 20 HP, 50 Hz, 50 m equivalent length, 15 m elevation
difference
The cooling capacity and heating capacity for this system are
found as shown below.)
●
Cooling operation
From the table, the correction coefficient for that horsepower
level is found to be 1.15.
From the graph, the base capacity change rate is found to be
92.0%.
92.0%
×
1.15 = 97.52% Capacity change rate is 97.52%.
56.0kW
×
97.52% = 54.6kW Cooling capacity is 54.6 kW.
●
Heating operation
From the table, the correction coefficient for that horsepower
level is found to be 1.06.
From the graph, the base capacity change rate is found to be
97.2%.
97.2%
×
1.06 = 103.0%
Because the calculation result exceeds 100%, the capacity
change rate is 100%.
63.0kW
×
100% = 63.0kW Heating capacity is 63.0 kW
The positive side for the elevation difference indicates that
the outdoor unit is installed at a higher position than the
indoor units. The negative side indicates the opposite.
