= 5.071kW (Same as Total capacity at 20°C Indoor DB / 15°C Indoor WB & 35°C Outdoor WB)*
Sensible capacity, SC
Extrapolation Method:

= 3.988kW
(b) Indoor Condition: 24°C DB, 15°C WB
Outdoor Condition: 40°C DB
Total capacity, TC
⇒

= 4.669kW (Same as Total capacity at 20°C Indoor DB / 15°C Indoor WB & 40°C Outdoor WB)*
Sensible capacity, SC
Extrapolation Method:

= 3.629kW
* This is due to 2 different conditions with same WB temperature, will have the same level of enthalpy. For
