Problem 10: Outside Air and Recirculated Air supplied without Reheating An engineer has been given the following data on a conditioned room: Sensible Heat Gain Latent Heat Gain Supply Air Outdoor Air Desired Room Condition 30 kW 15 kW 18 °C 35 °C DB and 24 °C WB 27 °C DB and 50% RH For ventilation, 15% is outdoor air, with the balance of the air requirement being recirculated from the room conditioned with some portion being by-passed around the cooling coil. There is no reheater; the desired room state is attained by the by-passing of air. It is found that the apparatus DP temperature of the coil is 10 °C. Find the following: a.) tons of refrigeration; and
