    Example: The sensible- and latent-heat gains in a space served by a single-zone air conditioner are 65 and 8 kW, respectively. The space is to be maintained at 24 oC and 50% relative humidity. The design conditions of outdoor air are 35 oC dry-bulb and 25 oC wet-bulb temperatures. For ventilation purposes outdoor air is mixed with recirculated air in a 1:4 proportion. When mixed air at the resulting conditions enters the cooling coil, the outlet air conditions are 12...
