An office is occupied by 30 persons who each produce 200 Btu/h (58W) of sensible heat and 0.25 lb/h (0.1kg/h) of moisture. The office is to be maintained at 72F (22C) and 50 percent relative humidity. Conditioned air is supplied at 60F (15C) to meet the sensible and latent loads. What is the sensible heat ratio (SHR) to meet the loads? What must the humidity ratio and mass flow rate of the supply air be? The office is located at sea level. (Assume that each person evaporates m=0.25 lb/h moisture at body temperature of 98.6F. Calculate the latent heat produced by each person as Q1=m*hfg,98.6F)
