Description

  The present invention relates to a ventilation system with a humidity control function.

  Conventionally, various ventilation systems have been provided.For example, when a heated room is ventilated in winter when humidity is low, the indoor humidity is discharged outside, and dry air is sent into the room. There is a problem that the humidity in the room is lowered.

  In particular, when the room is heated while being humidified with a humidifier, or when cooking in a pot in the room, the humidified air is exhausted to the outside.

  This invention makes it a subject to provide the ventilation system which can ventilate a room | chamber while suppressing the humidity fluctuation | variation in a room | chamber in view of the above problems.

The above problem is that the indoor intake port and the outdoor exhaust port are connected by an exhaust passage, the outdoor air supply port and the indoor outlet are connected by an air supply passage, and the fan is driven to In a ventilation system designed to be ventilated,
By a ventilation system with a humidity control function, which is equipped with a moisture absorption and desorption device that absorbs moisture from one of the air flowing through the exhaust passage and the air flowing through the air supply passage and releases the absorbed moisture to the other. Solved.

  In this ventilation system, for example, when a fan is driven to ventilate a room with high humidity in winter when the humidity is low, the moisture absorption and desorption device absorbs moisture from the high-humidity air in the room that passes through the exhaust passage. The minute air is released into low humidity air outside the air supply passage, and high humidity fresh air is sent into the room, so that the room can be ventilated without lowering the room humidity. In addition, there is no need for hydration to prevent a decrease in indoor humidity or less.

  In addition, when the fan is driven and the room is being dehumidified during the humid rainy season, the moisture absorption and desorption device absorbs moisture from outside high-humidity air that passes through the air supply passage, The indoor low-humidity air passing through the exhaust passage is dehumidified and fresh low-humidity air is sent into the room, so that the room can be ventilated without increasing the room humidity. In addition, it is not necessary or necessary to remove moisture to prevent an increase in indoor humidity.

  In the above ventilation system, when a heat exchanger that exchanges heat between the air flowing through the exhaust passage and the air flowing through the air supply passage is provided, that is, when the ventilation system is a heat exchange type, Not only can temperature fluctuations be reduced, humidity fluctuations can also be reduced, and comfortable ventilation with little fluctuations in temperature and humidity can be performed.

  Since the present invention is as described above, it is possible to ventilate the room while suppressing fluctuations in the humidity of the room, and there is little or no need for water replenishment for humidification and water removal for dehumidification.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  In FIG. 3 which shows the whole structure of the ventilation system of embodiment, 1 is a ventilation unit, This ventilation unit 1 is equipped with the fan 2 for ventilation inside, is installed in the back of the ceiling 3, and is provided in the ceiling surface 3 The air outlet 4 and the air inlet 5 are connected to each other through ducts 6 and 7, and the air inlet 9 and the exhaust outlet 10 provided on the outer wall 8 of the building are connected to each other through ducts 11 and 12. By driving the fan 2, outside air is taken into the room 13 through the air inlet 9 and the air outlet 4, and air in the room 13 is exhausted to the outside through the air inlet 5 and the outlet 10. 13 is designed to be ventilated.

  In the present embodiment, as shown in FIG. 1, the ventilation unit 1 is provided with a heat exchanger 14, and the air exhausted outside and the air supplied into the room 13 are heated by the heat exchanger 14. By exchanging, the temperature fluctuation of the room 13 due to ventilation is kept small.

  And in said heat exchange type ventilation system, the moisture absorption and desorption apparatus 15 is interposed in the ducts 11 and 12 which connect the ventilation unit 1, the exhaust port 10, and the air supply port 9, and the outside air taken in into the room | chamber 13 and outside The air exhausted in the air exchanges moisture.

  That is, as shown in FIG. 1, the moisture absorption / release device 15 is provided with a disk-like moisture absorption / release element 16 made of charcoal and the like, and the interior is partitioned into two chambers 18, 19 by a partition 17. Thus, the semicircular portion of the moisture absorbing / releasing element 16 is present in the first chamber 18 and the other semicircular portion is present in the second chamber 19. The moisture absorbing / releasing element 16 is centered on the rotating shaft 20. It is designed to rotate with a motor. The moisture absorbing / releasing device 15 is incorporated in a ventilation system with a first chamber 18 interposed in the duct 11 and a second chamber 19 interposed in the duct 12.

  In the above ventilation system, when the fan 2 is driven and the moisture absorbing / releasing element 16 is rotated in the winter when the humidity is low to ventilate the room 13 where the humidity is high and heating is performed, the inside of the moisture absorbing / releasing device 15 The moisture absorbing / releasing element 16 absorbs moisture from indoor high-humidity air passing through the duct 12, releases the moisture into the low-humidity air outside passing through the duct 11, and high-humidity fresh air is sent into the room 13. Therefore, the room can be ventilated without lowering the humidity in the room and without lowering the room temperature with the heat exchanger 14. Further, in the ventilation, it is not necessary or necessary to replenish water to prevent a decrease in indoor humidity.

  In the rainy season when the humidity is high, the fan 2 is driven and the moisture absorbing / releasing element 16 is rotated to ventilate the room 13 during dehumidification. Then, moisture is absorbed from outside high-humidity air passing through the duct 11, and the moisture is released to the low-humidity air in the room 13 passing through the duct 12. Fresh low-humidity air is sent into the room 13 to reduce the humidity in the room 13. The room 13 can be ventilated without being raised. In addition, it is not necessary or necessary to remove moisture to prevent an increase in indoor humidity during the ventilation.

  In the above ventilation system, switching means for switching whether or not moisture absorption / release is performed by the moisture absorption / release device 15 is provided, so that whether or not moisture absorption / release is performed by the moisture absorption / release device 15 can be selected. It is also good to keep it. Specifically, for example, as shown in FIG. 1, a bypass duct 21 may be connected to the duct 11, and the outside air may be supplied by bypassing the moisture absorbing / releasing device 15 by switching. In that case, it is possible to prevent moisture absorption / release contrary to the intention.

  In another embodiment shown in FIG. 2, the heat exchanger is omitted from the ventilation unit 1, and in this case as well, the room can be ventilated while suppressing humidity fluctuations in the room.

  Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above embodiment, the case where the ventilation unit 1 and the moisture absorption / desorption device 15 are provided separately is shown, but the moisture absorption / desorption device 15 is integrated with the ventilation unit 1 as a part of the ventilation unit 1. May be incorporated. In the above-described embodiment, the case where a disk rotating device is used as the moisture absorption / release device is shown, but other moisture absorption / release devices may be used. Further, the moisture absorption / release device may be provided on the ducts 6 and 7 side.

It is explanatory drawing which shows the ventilation system of embodiment. It is explanatory drawing which shows the ventilation system of other embodiment. It is explanatory drawing which shows the whole structure of the ventilation system common to both embodiment.
