A hospital operating room is being designed to use an HVAC system that delivers 100% outdoor air to avoid recirculating human associated bacteria. For summer operation, the air leaving the cooling coil and supplied to the space is at 55°F and 100% RH. The summer design loads are: 120,000 BTU/h (sensible) and 40,000 BTU/h (latent). You can assume that the specific enthalpy for moisture gains is ~1100 BTU/lbw. The indoor design temperature is 74°F. Outdoor design conditions are 100°F (dry bulb) and 35% RH. Determine the size of the cooling unit required (in BTU/h), the supply airflow rate required (in CFM), and the relative humidity of the air leaving the operating room.
