An air conditioned mall with a capacity of 1500 persons is to be maintained at 250C db temperature and 58% RH. The sensible and latent heat loads are 120 KW and 50 KW, respectively. The conditioned air enters the mall at 190C. For proper ventilation, 45% of the supply air is fresh air and the rest is recirculated air. Outside air is at 350C and 50% RH. Determine (a) the volume flow rate of recirculated air, (b) the apparatus dew point, and (c) the refrigeration load.
