Abstract

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 ㎛ in diameter, but the CADR was up to 0.25 m3/min. When the filter having 99.9% in collection efficiency was installed on the CAA, its CADR was 1.52 m3/min, while the CADR of commercial air purifier was 3.19 m3/min.
