Performance Table
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: ACC 75D – AMC 75D
Indoor Condition: 23°C DB, 15°C WB
Outdoor Condition: 37°C DB
Solution:
Overall
Based on the Performance table on Pg.41,
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.
1st Step
Extrapolation of Indoor WB
Find TC, SC for
(a) Indoor: 24°C DB, 15°C WB
Outdoor: 35°C DB
(b) Indoor: 24°C DB, 15°C WB
Outdoor: 40°C DB
2nd Step
Interpolation of Indoor DB
Find TC, SC for
(a) Indoor: 23°C DB, 15°C WB
Outdoor: 35°C DB
(b) Indoor: 23°C DB, 15°C WB
Outdoor: 40°C DB
3rd Step
Extrapolation of Outdoor DB
Find TC, SC for
(a) Indoor: 23°C DB, 15°C WB
Outdoor: 37°C DB
