An Industrial Look at Air Recirculation.
NIOSH 1976 Feb:127-133
Air recirculation in industry is becoming an economic necessity. The procedure for developing an energy conservation program for air circulation is described. Local exhaust systems and the low-volume, high-velocity exhaust method use less air to control contaminants. Radiant heat can be reflected away from workers and back into the work process. Before using heat exchangers to remove heat, every effort should be made to recirculate clean air into the plant, clean the effluent and recirculate it or recirculate contaminated air over the process. Energy will be used more efficiently without exposing workers to hazards or reducing their comfort.
