Question

10. A building has a total heating load of 59 kW. The sensible heat ratio (SHR) of the indoor space is 0.8, and the indoor conditions must be maintained at 22°C dry-bulb (db) and 40% relative humidity. Outdoor air at 4°C db and 20% relative humidity is required at a rate of 0.5 \\\text{m}^3/\\text{s} \. The supply air to the space is at 49°C db. Based on sea-level pressure, calculate the following: (a) The amount and condition of the air supplied to the space (b) The temperature rise of the air passing through the furnace (c) The amount of water required by the humidifier at 10°C (d) The capacity of the furnace

Step 1

8 \) - Indoor conditions: \( T_{in} = 22^\circ C \) db, \( RH_{in} = 40\% \) - Outdoor air: \( T_{out} = 4^\circ C \) db, \( RH_{out} = 20\% \) - Outdoor air flow rate, \( V = 0.5 \, m^3/s \) - Supply air temperature, \( T_{supply} = 49^\circ C \) db - Show more…
