Supply air
Warm air leaving a computer server room after recovering waste heat (State-1 in Figure-Q1) is at
34 °C (dry bulb), 30% RH and flows at a rate of 1.6 m³/s. This air is passed over a cooling coil and
cooled to 23 °C (State-3). This cooled air is then mixed with outdoor air. Outdoor air (State-2) is at
13 °C (dry bulb), 40% RH. The two air streams mix at a 1:1 mass ratio. This mixed air is then
supplied to another room.
