Outdoor air conditions are: 28°C db, 19.5°C wb Return air conditions are: 22°C db, 50% RH. The mixture air condition outlet the cooling coil are: 10°C db, 0.00735 kg/kgda Draw the system on the Psychrometric chart, then calculate: 1. Cooling coil load. 2. Room sensible heat. 3. Room latent heat. 4. Fresh (outdoor) load. 5. Duct and fan heat gain 6. Sensible heat ratio SHR. If the supply air temperature increases with a value 1ºK due to fan motor heat gain and 2ºK due to duct heat gain.
