Given the following design information for a build-
ing:
Outside air conditions: 92\deg FDB,76\deg F WB
Inside air conditions: 80\deg FDB,50%RH
Sensible heat gain: 68,500Bt(u)/(h)r
Latent heat gain: 29,350Bt(u)/(h)r
Ventilation requires that all air supplied to the
building interior must be outdoor air.
Temperature difference between inside design
dry-bulb and supply air is to be 20 degrees.
Using a cooling coil bypass factor of 0.10 , deter-
mine (a) the room sensible heat factor; (b) the
supply air quantity, cfm; (c) the apparatus dew-
point temperature; (d) the reheat quantity, Bt(u)/(h)r.
