PROBLEM TO BE SOLVED: To attain miniaturization and space saving while reducing power consumption in an air shower. SOLUTION: An alternating current induction motor and a multiblade fan are conventionally used as a driving blast source for blasting a jet air current through a punkah louver 7, but a direct current motor (a DC brushless motor in the figure) 2A and a turbo fan 3A are used in this constitution to attain particularly energy saving. A nearly half power-saving effect can be obtained in comparison with the case of using the alternating current induction motor and the multiblade fan. COPYRIGHT: (C)2005,JPO&NCIPI |
