Are partitioned by the moisture permeable membrane 5a. The moisture permeable membrane 5a may be provided at a position closer to the indoor (outdoor) 13 side than the heat exchanger 4, or may be provided at a position closer to the outdoor (outdoor) 19 side than the heat exchanger 4. However, as shown in FIG.

Cloths, nonwoven fabrics and the like can be used, and those impregnated with ethylene glycol, lithium chloride, lithium bromide or the like are preferably used.

Next, the operation of the ventilation device will be described. When the motors 18 are driven to operate the fans 16 and 17,
The air in the room 13 is sucked in from the suction port 14 by the action of the fan 16, passes through the exhaust path 33 of the heat exchanger 4 from the exhaust path 1, and is connected to the exhaust port 3, which is an opening on the outdoor 19 side of the exhaust path 1.
Air is exhausted from 6 to the outside 19. At the same time, at the same time, the outdoor air is sucked in from the intake port 37, which is the opening on the outdoor 19 side of the intake passage 2, by the action of the fan 17, passes through the intake passage 34 of the heat exchanger 4 from the intake passage 2, and It is introduced into the room 13 from the inlet 15.

Here, in winter, the one electrode 23a and the substrate 24a facing the exhaust passage 33 of the Peltier module 3 serve as a heat absorbing portion 25, and the intake passage 3 of the Peltier module 3
The other electrode 23b facing substrate 4 and substrate 24b are
The direction of power supply to the Peltier module 3 is set so that When warm air in the heated room passes through the exhaust passage 33 of the heat exchanger 4 from the exhaust passage 1, the heat of this air is absorbed by the heat absorbing portion 25 of the Peltier module 3.
At the same time, the absorbed heat is radiated from the heat generating portion 26 of the Peltier module 3, and when the cool air outside the room 19 passes through the intake passage 34 of the heat exchanger 4 from the intake passage 2, the air is cooled. Is heated by the heat generating section 26. As described above, the heat exchanger 4 exchanges heat between the warm air in the room 13 passing through the exhaust passage 1 and the cool air in the outdoor 19 passing through the intake passage 2, and the air outside 19 is warmed up through the inlet 15. When air is introduced into the room and the room 13 is ventilated with fresh air outside 19, the efficiency of heating the room 13 can be prevented from lowering.

At this time, during heating in winter, the air in the room 13 is humidified to increase the humidity, the air in the outside 19 is dry, and the humidity of the air in the outside 19 is low. The humid air in the room 13 passes through the exhaust passage 1 and the outside 19.
Low humidity air passes through the intake passage 2 respectively,
The moisture (humidity) in the air moves from the high-humidity exhaust passage 1 to the low-humidity intake passage 2 through the water-permeable membrane 5 a as shown by the arrow A in FIG. The air absorbs moisture and the humidity is increased. In this way, fresh air in the outdoor room 19 is supplied to the indoor room 1 with the humidity increased.
3 and can be ventilated without causing a large change in the humidity of the room 13.

In the summer, one of the electrodes 23a and the substrate 24a facing the exhaust passage 33 of the Peltier module 3 becomes the heat generating portion 26, and the intake passage 34 of the Peltier module 3
The direction of energization to the Peltier module 3 is set so that the other electrode 23b facing the substrate and the substrate 24b become the heat absorbing portion 25. Then, the hot air outside 19 is supplied to the intake passage 2.
When passing through the intake passage 34 of the heat exchanger 4, the heat of this air is absorbed by the heat absorbing portion 25 of the Peltier module 3, and the air in the intake passage 2 is cooled. And the heat absorbing section 25
The heat absorbed from the heat generating part 26 of the Peltier module 3
Then, the heat is radiated into the exhaust passage 33, and the cool air in the room 13 receives this heat when passing through the exhaust passage 33 of the heat exchanger 4 from the exhaust passage 1 and is discharged to the outside 19. As described above, the heat exchanger 4 allows the room 13 passing through the exhaust passage 1 to be moved.
The heat is exchanged between the cold air of the outside and the hot air of the outside 19 passing through the intake passage 2, and the air of the outside 19 is cooled and introduced into the room 13 from the inlet 15 and the fresh air of the outside 19 When performing ventilation, it is possible to prevent the efficiency of cooling of the room 13 from being reduced.

At this time, during cooling in summer, the air in the room 13 is dried by dehumidification, and the air outside 19 is high in humidity. The low-humidity air in the room 13 passes through the exhaust passage 1 and the high-humidity air outside the room 19 passes through the intake passage 2. 11 moves through the moisture permeable membrane 5a as shown by the arrow B in FIG.
The air taken in from 9 is dehumidified and its humidity decreases. In this way, fresh air outside the room 19 can be introduced into the room 13 while keeping the humidity low, and ventilation can be performed without causing a large change in the humidity of the room 13. is there.

Here, when heat exchange between the air passing through the exhaust passage 33 and the air passing through the intake passage 34 is performed by the heat exchanger 4, the flow of air passing through the exhaust passage 33 and the intake passage 34 is changed. Are in the same direction, the heat exchange rate is theoretically limited to 50%. However, if the air flow passing through the exhaust flow path 33 and the intake flow path 34 is a counter flow in opposite directions, the heat exchange rate becomes Can theoretically approach 100%, and the same can be said for the heat exchanger 4 using the Peltier module 3. In particular, in the heat exchanger 4 using the Peltier module 3, as shown in FIG.
When the flow of air passing through 4 is made a parallel flow in the same direction, a temperature reversal phenomenon occurs as shown in FIG. 14B and the efficiency becomes poor, but as shown in FIG. When the flow of air passing through the intake passage 34 is made to be a counter flow in the opposite direction,
As shown in FIG. 15B, the heat exchange rate can be made close to 100%. For this reason, as shown in each of the above embodiments, in the heat exchanger 4 of the present invention, the flow direction of the air passing through the exhaust passage 33 is opposite to the flow direction of the air passing through the intake passage 34. It is formed in a counter flow system.

The temperature of the air passing through the exhaust passage 33 and the intake passage 34 of the heat exchanger 4 is controlled by the inlets 33a, 34a.
The temperature distribution gradually changes from “a” to the outlets 33b and 34b. Then, as shown in FIG.
If the heat absorbing portion 25 and the heat generating portion 26 of the Peltier module unit 30 are formed so as to be continuous in the flow direction of the air passing through the exhaust passage 33 and the intake passage 34, the heat absorbing portion 25
The temperature of the heat generating section 26 is made uniform by heat conduction, and it becomes difficult to independently set the operating temperatures of the Peltier elements 22a and 22b. Therefore, in the present invention, as shown in each of the above embodiments, a heat insulating material 29 is interposed between the heat absorbing portions 25 and the heat generating portions 26 adjacent to each other in the Peltier module unit 30 so that the air passing through the heat exchanger 4 is removed. The Peltier module unit 30 is arranged so that the direction in which the heat absorbing portion 25 and the heat generating portion 26 are insulated by the heat insulating material 29 is the same as the direction of flow. If the heat absorbing portions 25 and the heat generating portions 26 are not continuous in the flow direction of the air passing through the exhaust flow channel 33 and the intake flow channel 34, the heat absorbing portions 25 and the heat generating portions 26 do not conduct heat, respectively. Corresponding to the temperature distribution of the air passing through the exhaust passage 33 and the intake passage 34, the inlets 33a, 34a to the outlets 33b,
It is easy to independently set the operating temperature of each of the Peltier elements 22a and 22b up to 34b, and it is possible to increase the efficiency of heat exchange.

The same applies to the fins 31 provided on the heat absorbing portion 25 and the heat generating portion 26 of the Peltier module 3. In the present invention, as shown in the above embodiments, the exhaust passage 33 and the intake passage 34 are provided. The fins 31 are independently separated by the heat absorbing portions 25 and the heat generating portions 26 in the flow direction of the air passing through the fins 31 so that the heat absorbing portions 25 and the heat generating portions 26 are not connected by the fins 31 in the flow direction of the air. This prevents heat conduction between the heat absorbing portions 25 and between the heat generating portions 26 via the fins 31.

FIG. 9 shows a configuration in which the heat exchanger 4 is formed by arranging a plurality of Peltier module units 30 in parallel on the ventilation box 32. The ventilation box 32 is partitioned by the plurality of Peltier module units 30. Thus, the exhaust passages 33 and the intake passages 34 are alternately formed in a plurality of stages in the ventilation box 32. Opening the heat exchanger 4 at both ends of each exhaust passage 33 into the exhaust passage 1 and each intake passage 3
4 are communicated with the intake passage 2 at both ends thereof,
The ventilation device of the present invention can be formed by installing the device in the ventilation box 32.

40 can be attached. Each mouthpiece 39,
A plurality of upper and lower passage openings 41a and 41b are provided alternately in the upper part 40, and each passage opening 41a and 41b is a mouthpiece 3
Openings are formed on the slopes 9 and 40. The openings on the slopes are joined to the openings on both sides of the exhaust box 32, and the openings 4
1a is opened on one surface sandwiching the right angle of the mouthpieces 39 and 40, and the passage opening 41b is opened on the other surface sandwiching the right angle of the mouthpieces 39 and 40 (the closed portion is hatched in FIG. 10). Shown). The air in the exhaust passage 1 flows through the exhaust passage 33 of the heat exchanger 4 through the passage 41a, and the air in the intake passage 2 flows through the intake passage 34 of the heat exchanger 4 through the passage 41b. I have to do it. Therefore,
The passage 41a of each exhaust passage 33 of the heat exchanger 4 can be combined on one surface sandwiching the right angle of the mouthpieces 39, 40, and the passage 41b of each intake passage 34 can be connected to the mouthpiece 39, 40. It can be put together on the other side of the right angle.

Here, when the temperature of the indoor air is 20 ° C. and the relative humidity is 60% RH, the temperature of the outdoor air is 5 ° C. and the relative humidity is 40% RH, the indoor ventilation system shown in FIG. FIG. 12 is a graph showing the results of ventilation when the time required to replace the entire amount of air is 2 hours. FIG. 12A shows a change in the room temperature.
The results are shown by solid lines. In this case, by adjusting the amount of electricity supplied to the Peltier module 3 of the heat exchanger 4, FIG.
