PROBLEM TO BE SOLVED: To overcome unpleasant sweltering night in summer while saving electricity expense by using a convection promoting wind flow fan, and to use the convection to save heating cost in winter. SOLUTION: The "convection promoting wind flow fan" is a vertical duct type ventilation cylinder inserted to a ventilation port for an air conditioner in each room. A small fan, a power source, a fire alarm mainly used for sensing smoke and a display of a temperature difference between indoor upper and lower sides are attached to the upper part of a duct. By lowering the voltage of a small DC fan to a level preventing wind noise and "wind flow" is produced in the indoor space. COPYRIGHT: (C)2010,JPO&INPIT |
