To obtain the Total capacity and Sensible capacity for
(a) Indoor Condition: 23°C DB, 15°C WB
Outdoor Condition: 35°C DB

= 2.558kW (Same as Total capacity at 20°C Indoor DB / 15°C Indoor WB & 35°C Outdoor WB)*
Sensible capacity, SC
Interpolation Method:
⇒
24º C – 20º C
=
1.990kW – 1.181kW
24º C – 23º C 1.990kW – y

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