The conventional ventilation device with a heat exchanger is configured as described above, and by operating the exhaust blower (8) and the air supply blower (9), indoor air is supplied from the indoor suction port (2) to the box ( 1)
It is sucked in, passes through the heat exchanger (10) in the exhaust passage (6), is blown out from the outdoor air outlet (5), and is discharged to the outside of the room. The outdoor air is sucked into the box (1) through the outdoor suction port (3), passes through the heat exchanger (10) in the air supply passageway (7), and is blown out from the indoor side outlet (4) into the room. Be supplied with air. At this time, heat exchange is performed in the heat exchanger (10) between the exhaust flow and the supply air flow, and the exhaust heat is recovered to reduce the heating and cooling load. On the other hand, in the intermediate period when the heat exchanger (10) is not needed, such as in spring and autumn, the drive machine (16) is driven to rotate the damper (14) to open the bypass passage (13) and heat exchange. The exhaust passage (6) to the container (10) is closed. As a result, the exhaust flow is exhausted through the bypass passage (13), and since the air passage resistance is small, a large amount of air can be obtained.

In the ventilation device with a heat exchanger configured as described above, in the air conditioning ventilation using the heat exchanger (10), the bypass passages are blocked by the bypass dampers (34a) and (34b) as shown in FIG. In addition, by closing the air path switching damper (37) and operating the respective blowers (8) and (9), the indoor air passes through the duct from the indoor suction port (2) to the indoor suction chamber (2). 29) and the opening (3
0) → Indoor suction passage (27) → Room (20) → Heat exchanger (1
0) → chamber (17) → opening (23) → exhaust blower (8) chamber (2
Exhaust blower (8) through the exhaust passage (6) leading to 2)
Is blown out from the outdoor air outlet (5) and discharged to the outside through the duct. Outdoor air is sucked into the outdoor suction chamber (26) from the outdoor suction port (3) through the duct, and the chamber (19) → heat exchanger (10) → chamber (18) → opening (25) → air supply The air passes through the air supply passage (7) leading to the blower chamber (24), and is blown out from the indoor side outlet (4) by the air blower (9) to be supplied to the room through the duct. At this time, in the heat exchanger (10), heat exchange is performed between the exhaust flow and the supply air flow, and the exhaust heat is recovered to reduce the heating and cooling load. On the other hand, when it is desired to perform ventilation such as air supply and exhaust in the middle period that does not require heating and cooling such as spring and autumn, or when it is desired to perform ventilation such as exhaust, bypass dampers (34a) and (34b) and wind as shown in Figs. 4 and 5. The path switching damper (37) is rotated so that they are superposed. As a result, the outdoor outlet (5) communicates with the suction port of the exhaust blower (8), and the outlet of the exhaust blower (8) communicates with the indoor suction port (2) via the bypass passage (13). To do. By operating each of the blowers (8) and (9) in this state, air is blown from the outdoor inlet (3) to the indoor outlet (4) in the same manner as the air conditioning ventilation, but for exhaust. The air blown by the blower (8) is sucked in from the outdoor air outlet (5), and the opening (32) → bypass passage (1
3) → Opening (33) → Passes through a bypass ventilation path leading to the indoor suction chamber (29) and is blown out from the indoor suction port (2). In this way, since the exhaust blower (8) switches the air passage in the same direction as the air supply blower (9), air can be supplied by both blowers (8) and (9), and a large amount of air is generated. Will be obtained. The heat exchanger (10) becomes dirty and needs to be cleaned by air-conditioning ventilation or normal ventilation as described above, but the cover (3
8) can be removed and the heat exchanger (10) can be pulled out to be cleaned with a vacuum cleaner or the like, and the heat exchanger (10) can be inserted and removed with the suction ports (2) (3) and the air outlet (4) ( Since it is performed so as to be orthogonal to the forming direction of 5), the supply and exhaust pipes do not interfere. Further, since the rotating shafts of the exhaust blower (8) and the air supply blower (9) are provided orthogonally to the insertion / removal direction of the heat exchanger (10), the vane casing (11) having a large size. Are arranged so as to be parallel to the heat exchanger (10), and the depth dimension of the box body (1) is reduced. The width dimension is determined by the dimensions of the heat exchanger (10).
