<P>PROBLEM TO BE SOLVED: To provide a regenerative heat exchange type ventilation fan achieving substantially the same performance with an extremely simple regenerative heat exchanger and one air blower. <P>SOLUTION: Heat is exchanged by accumulating heat based on an inside/outside air temperature difference in a regenerative heat exchanger and dissipating the accumulated heat by repeating air suction and air exhaustion by one air blower as in the case where fresh air is taken into the lungs by breathing. Because an exchanger 4 has a simple structure formed by only spirally rounding corrugated plates 5 and the ventilation fan can be constituted coaxially with a motor, it is possible to reduce the size and cost. <P>COPYRIGHT: (C)2012,JPO&INPIT |
