Calculation Steps

Interpolation method can be used to get the total capacity, TC and sensible capacity, SC and power input,
PI at those temperatures which are not stated out in the table. Extrapolation method are not allowed to be
used to get the TC, SC and PI.
Example:
Model: ART200A
Indoor Condition: 25°C DB, 17°C WB
Outdoor Condition: 37°C DB
Fan Speed: High (6710CFM)
Solution:
Overall
Based on the Performance Table
1. Refer to the Indoor DB column,
- 25°C is located between 24°C and 27°C for 16˚CWB (Thus, Interpolation need to be applied)
- 25°C is located between 24°C and 27°C for 19˚CWB (Thus, Interpolation need to be applied)
2. Refer to the Indoor WB column,
- 17°C is located between 16°CWB and 19°CWB for 25°CDB
(Thus, Interpolation need to be applied)
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.
