13- A winter air conditioning unit consists of a preheating coil, a spray system (adiabatic humidifier), and reheating coil. The unit is designed to handle 8000 kg/h of fresh air. The total heat loss from the space is 9 kW with SHF-0.8. The outside air enters the unit at 7°C DBT, 4°C WBT. The air leaves the spray system at 90% RH. The unit delivers air at 26 °C DBT, 30% RH. Determine: a) Draw the psychometric cycle and line diagram. b) The condition maintained inside the space c) The quantity of water consumed during humidification d) The heating capacities of the preheating coil and reheating coil.
