Question
A building has a calculated cooling load of 410 kW. The latent portion of the load is
100 kW. The space is to be maintained at 25 C DBT and 50% RH. Outdoor air at 38 c and
50% RH, and 10% by mass of the air supplied to the space is outdoor air. Air is to be
supplied to the space at not less than 18 c. Find::
S
a- The minimum amount of air supplied to the space in m³\s,
b- The volume flow rates of the return air, exhaust air, and outdoor air,
c- The conditions and volume flow rates of the air entering the cooling coil,
d- The capacity, apparatus dew point temperature, and by pass factor of the cooling
coil.
