<P>PROBLEM TO BE SOLVED: To provide a heat exchange type ventilating device capable of reducing pressure loss by lowering height of a main body. <P>SOLUTION: The outdoor side is connected through a duct 45 to forcedly take in outside air to be supplied to the indoor side, and the indoor side and the outdoor side are connected to each other through a duct 46, so that inside air is discharged to the outdoor side in the ventilating device. At a position of a supply air blow passage in which outside air introduced from the outdoor side through the duct 45 into a ventilating device main body 1 is supplied to the indoor side crosses a discharge air blow passage in which inside air is forcedly discharged from an indoor discharge air port 5 provided in a lower surface of the ventilating device main body 1 to the outdoor side, a heat exchange element part 3 having a heat transmitting surface shaped like a parallelogram through which inside air and outside air are heat-exchanged is disposed. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
