Calculation Steps
Interpolation method can be used to get the total cooling capacity, TC and sensible cooling capacity, SC
and power input, PI at those temperatures which are not stated out in the table. Extrapolation method is not
allowed to be used.

Solution:
Based on the Performance Table,
1. Refer to the Indoor DB column,
- 25°C is located between 24°C & 27°C for 16°C WB.
- 25°C is located between 24°C & 27°C for 19°C WB.
- Thus, Interpolation needs to be applied.
2. Refer to the Indoor WB column,
- 17°C is located between 16°C & 19°C for 25°C DB.
- Thus, Interpolation needs to be applied.
3. Refer to the Outdoor DB column,
- 37°C is located between 35°C & 40°C.
- Thus, Interpolation needs to be applied.
