Interpolation
and
Extrapolation
method can be used to get the total capacity, TC and sensible capacity, SC
at those temperatures which are not stated out in the table.
Example:
Model:
MVF 030AR - MLC 030CR
Indoor Condition:
23°C DB, 15°C WB
Outdoor Condition:
37°C DB
Solution:
Overall
Based on the Performance table on Pg. 18,
1. Refer to the Indoor DB column,
-
23°C
is located between 20°C and 24°C (Thus, Interpolation need to be applied)
2. Refer to the Indoor WB column,
-
15°C
only available in the case of Indoor DB = 20°C. (Thus, Extrapolation between 16°C WB
and 17°C WB during 24°C indoor DB is required)
3. Refer to the Outdoor DB column,
-
37
°C
is located between 35°C and 40°C. (Thus, Interpolation need to be applied)
Please follow the steps below in order to get the required capacity.
