b) 318.1 KW

c) 92.11 KW

Outside air at 32°C and a pressure of 1.013 bar is drawn into an air handling unit at a rate of 5m3/s. The air has a relative humidity of 66.5%. The unit must deliver air to a building at 25°C and 36%relative humidity. Determine:

i. To what temperature must the entering air be cooled? (assume the bypass factor is zero)

ii. How much energy must be removed at the cooling coil

iii. How much energy must be supplied by the reheaters.
