PLEASE ANSWER ASAP A sample space is to be maintained at 25⁰Cdb, 18⁰Cwb. The space has a sensible load of 40KW and SHF = .9. Outdoor conditions are 35⁰C and 50%RH. Assume that 10% by volume of the supply air to the room is outdoor air. The outside air passed through the cooling equipment and then mixed with the recirculated air and the temperature of the air supplied to space should not be lower than 18⁰C. Determine (a) mass of air supplied to the space, Kg/s, (b) tons of refrigeration required of the cooling equipment (c) apparatus dew point temperature (d) supply fan capacity, cfm.

1. A room is to be maintained at 25°Cdb and 15°Cwb. The air supplied to the room is about
90%RH. Outside air is at 35°Cdb and 50%RH. The amount of recirculated air is 75% of the total
air supplied to the room. If the sensible and latent heat loads are 2,800,00OKJ/hr and 700,000
KJ/hr respectively, Determine the (a) total amount of air supplied to the room in Kg/s, (b)
amount of outside air, m/s, (c) refrigerating capacity of the cooling equipment, Hp, and (d)
average coil surface temperature to be maintained.
