An office for seating 30 occupants is to be maintained at 22°C DB and 55% RH. The outdoor conditions are 36°C DB and 27°C WB. The various loads in the office are: Solar heat gain = 8,500W; Sensible heat gain per occupants = 83 W; Latent heat gain per occupant = 100W; Lighting load = 2,500W; Sensible heat load from other sources = 12,000W; and Infiltration load = 15 m3/min. Assuming 40% fresh air and 60% of recirculated air passing through the evaporator coil and the by-pass factor of 0.12, determine the following: A) The Dew Point Temperature of the coil, in degrees Centigrade. B) The Capacity of the Airconditioning Plant, in Tons of Refrigeration.
