6. PERFORMANCE DATA

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: AWM 10G / ALC 10C

Indoor Condition: 23°C DB, 15°C WB

Outdoor Condition: 37°C DB

Solution:

Overall

Based on the Performance table of AWM 10G / ALC 10C

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.

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

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

Step

Interpolation of Outdoor DB

Find TC, SC for

(a) Indoor : 23°C DB, 15°C WB

Outdoor : 37°C DB
