Question

In an air-conditioning system 200 m³/min air is cooled and dehumidified from 32⁰C and specific humidity 0.014 kg/kg of dry air to 16⁰C and specific humidity 0.011 kg/kg of dry air. Draw the phychrometric process and calculate the sensible heat factor and calculate the sensible heat factor. Average property values may be taken as:

Density of air, r = 1.2 kg/kg o dry air

Specific heat of air, C_p = 1.0216 kJ/kg K

Latent heat of water, h₁ = 2500 kJ/kg
