O 1:
28.5 m/m of room air at 25.5 °C DBT and 50 % RH is mixed with 28.5 m/m of
outside air at 38.5 °C DBT and 27 °C WBT. Draw the schematic figure for the process
and find:
a- The ventilation cooling load and the conditions of air after mixing.
b- The above mixture of air is passed through an air conditioning equipment. If the wet
bulb temperature of air after the equipment is 14.5 °C, determine the heat removed by the
equipment.
02:
For standard conditions calculate the cooling load per square meter due to conduction
through a flat roof (101.6 mm light weight concrete) with and without suspending ceiling
at 1 PM.:
a- Assume a light surface.
b- Assume a dark surface.
