For a 6,000 Square feet combination gym and exercise, if is desire to reduce outdoor air intake to a minimum by filtering and recalculating. Design a system using filters having an efficiency of 0.5 and a pressure loss of 0.14 in-wg at 350 ft/min face velocity. Pressure loss should not exceed 0.2 in-wg. Outdoor air contaminants are negligible. Discuss how the choice of a filter would be influenced in this case should the cooling load requires a larger supply air rate than the ventilation.
