Dang ventilation Shi, part indoor return was ventilation device taking outdoor, at indoor air density declined, produced negative pressure (relative Yu outdoor pressure), due to indoor, and outside has pressure poor, outdoor of fresh air on through doors and Windows sewing into indoor, reached improved indoor air quality of purpose; or is will outdoor of air directly pumping house within, at indoor air density rose, produced are pressure (relative Yu outdoor pressure), due to indoor, and outside has pressure poor, outdoor of dirty air on through doors and Windows sewing was for out, To achieve the aim of improving indoor air quality.
(3) under what circumstances use ventilation air conditioning.
