Summary

IN THIS PAPER A CLEAN ROOM WITH A LOCALLY AIR-BALANCED SUPPLY-EXHAUST VENTILATION SYSTEM INSTALLED AT THE CEILING IS ST FLOW AND DIFFUSION FIELDS IN THIS ROOM ARE ANALYZED BY BOTH FLOW VISUALIZATION AND MEASUREMENT. THE RESULTS OBTAINED FROM MODEL EXPERIMENTS OF THIS SYSTEM ARE COMPARED WITH THOSE OF CONVENTIONAL FLOWTYPE CLEAN ROOM WITH EXHAUST OPENINGS AT THE WALL. IT IS CONFIRMED BY THE MODEL EXPERIMENT THAT THE LOCALLY CLOSED-CIRCUIT VENTILATION SYSTEM WITH SUPPLY AND EXHAUST OPENINGS AT THE CEILING IS A USEFUL METHOD FOR CONTAMINATION CONTROL.
