Complete solution
Air flowing at the rate of 80m³ /min at 35°C dry bulb temperature and
50% relative humidity is mixed with another stream flowing at the rate of 20m3 /min at
21°C dry bulb temperature and 50% relative humidity. The mixture flows over a cooling
coil whose apparatus dew point temperature is 5°C and by-pass factor is 0.2. Find dry
bulb temperature and relative humidity of air leaving the coil. If this air is supplied to an
airconditioned room where dry bulb temperature of 21°C and relative humidity of 50%
are maintained, and determine: a) Room sensible heat factor; and b) Cooling load
capacity of the coil in tons of refrigeration.
