Abstracts
In this study, the clean air delivery rate (CADR) of ceiling air circulator (CAA) was determined under indoor
environmental simulation conditions. An air filter was used to provide air cleaning ability to the CAA. The CADR of
filter adapted CAA was evaluated and compared with the value of commercial air purifier. The installation of
mesh-shaped filter on the CAA showed particle reduction effect on the particles over 0.4 ¥ìm in diameter, but the
CADR was up to 0.25 m
3
/min. When the filter having 99.9% in collection efficiency was installed on the CAA, its
CADR was 1.52 m
3
/min, while the CADR of commercial air purifier was 3.19 m
3
/min.
