The following data refers to an air conditioning system to be designed for an industrial process for hot and wet climate: outside conditions=30 0c dbt and 75% rh inside required condition=200c dbt and 60% rh the required condition to be achieved first by cooling and dehumidifying and then by heating. if 20m3 of air is absorbed by the plant every minute, calculate: a. capacity of heating coil in kw b. capacity of the cooling coil in tones of refrigeration c. amount of water removed per hour d. by-pass factor of the heating coil if its surface temperature is 350c
a) Capacity of the heating coil: This would depend on the specific heat capacity of air and the temperature rise required to achieve the desired condition.
b) Capacity of the cooling coil: This would depend on the heat transfer rate required to achieve the desired condition.
c) Amount of water removed: This would involve calculating the difference in humidity ratios between the outside and inside conditions and the mass flow rate of air.
d) Bypass factor of the heating coil: This would involve understanding the heat transfer mechanism and the effect of bypassing air over the heating coil.
