Description

Ventilating device

The present invention relates to a ventilator, and more particularly, in a total heat exchange type ventilator in which heat is exhausted from an outdoor air to be supplied, and an indoor air to be evacuated, which can rapidly exhaust pollutants in a room and supply fresh air rapidly. It relates to a ventilation device.

The air in an enclosed space increases the carbon dioxide content over time due to the breathing of living things, which interferes with the breathing of living things. Therefore, if many people stay in a narrow space such as an office or a vehicle, it is necessary to frequently replace the indoor air with fresh air. At this time, a commonly used ventilation device.

Most conventional ventilation apparatuses employ a method of forcibly discharging only indoor air to the outside using a single blower. However, if only one air is forced out by using one blower, the indoor cold air or heat is discharged to the outside without filtration, and the outdoor air is heated without heat exchange through a door or window gap. The cost of cooling was unnecessarily high.

In addition, due to the sudden inflow of cold air and heat from inside to outside people suddenly change the temperature of the interior people there is unpleasant feelings, especially in the state that the indoor window or door frame closed to discharge only the indoor air to the outside In this case, the inflow of fresh air may be blocked and oxygen deficiency may occur, and the humidity of the indoor air is not controlled at all. However, even though a ventilation device is provided, it does not maintain a comfortable indoor environment. there was.

In order to solve this problem, a total heat exchange type ventilation device for first exchanging outdoor air with indoor air discharged to the outside and then supplying the indoor air has been proposed.

Figure 1 schematically shows the structure of a general electrothermal exchange ventilator.

As shown in FIG. 1, an air supply duct 10 is provided inside a box-shaped case 1 to guide outdoor air to an interior, and the air duct intersects with the air supply duct at a predetermined position, and the air is guided to the outside. Duct 30 is provided. In addition, an electric heat exchanger (5) is provided in which the outdoor air that is supplied at the point where the air supply duct 10 and the exhaust duct 30 intersect with the indoor air that is exhausted is heat-exchanged.

An air supply inlet 11 is formed at one end of the air supply duct 10 to communicate with the outside, and an air supply outlet 13 is formed to communicate with the room at the other end thereof, and an air exhausted to communicate with the room at one end of the exhaust duct 20. An inlet 31 is formed and an exhaust outlet 33 is formed at the other end in communication with the outdoors.

At this time, the air supply duct 10 and the exhaust duct 30 do not interfere with each other while crossing the inner space of the case 1 up and down with respect to the heat exchanger, respectively. The air supply duct 10 is formed by a partition wall 10a extending to the air supply inlet port 11 and a partition wall 10b extending to the air supply outlet port 13 around the total heat exchanger 5. 30) is also possible because it is formed by the partition 30a extending to the exhaust inlet 31 and the partition 30b extending to the exhaust outlet 33 around the total heat exchanger.

An air supply fan 15 for forcibly sucking outdoor air is provided on the air supply outlet side of the air supply duct 10, and an exhaust fan 35 for forcibly exhausting indoor air is provided on the air outlet side of the exhaust duct 30. do.

On the other hand, the heat exchanger (5) has a hexahedron shape, the upper and lower edges of which are supported by the case (1) and the left and right edges of the heat exchanger (5) are supported by a plurality of partitions partitioning the air supply duct (10) and the exhaust duct (30). A plurality of air supply passages 5a communicating with the air supply duct 10 and a plurality of air exhaust passages 5b adjacent to the air supply passage and communicating with the exhaust duct 30 are provided. Although not shown, a heat exchange membrane having excellent heat conduction efficiency is provided at the boundary between the air supply passage 5a and the exhaust passage 5b.

At this time, the part shown on the right side in the drawing is the air supply passage 5a, and the part shown on the left side is the exhaust passage 5b.

Referring to the operation of the electrothermal exchange system ventilator configured as described above are as follows.

First, when indoor air is contaminated to some extent, power is supplied to the exhaust fan 35 while the indoor air flows into the exhaust duct 30 through the exhaust inlet 31, and then passes through the exhaust passage 5b of the total heat exchanger. It is discharged to the outside through the exhaust outlet 33.

At the same time, while supplying power to the air supply fan 15, fresh outdoor air flows into the air supply duct 10 through the air supply inlet 11, and then passes through the air supply passage 5a of the heat exchanger, and supplies the air supply outlet 13. Through the room.

At this time, the indoor air and the outdoor air passing through the heat exchanger (5) exchange heat through the heat exchange membrane. Specifically, the heat exchange occurring in the total heat exchanger 5 includes sensible heat exchange occurring between the outdoor air to be supplied and the indoor air to be exhausted, and the hot air of the indoor or outdoor air is dew point temp. It becomes the latent heat exchange by the condensate produced | generated while being in the following states.

As described above, in the case of an electrothermal exchange type ventilator, outdoor air that is supplied when the room is cooled or heated is primarily heat-exchanged with the indoor air and then introduced into the room, thereby preventing a sudden rise or fall of the room temperature. Can be.

However, in the case of the above-mentioned ventilation apparatus, since the indoor air to be exhausted is necessarily discharged through the total heat exchanger (5), there is a disadvantage that it is not possible to quickly remove the indoor pollution source. That is, in a room where a large amount of gaseous odors or odors or harmful gases to human body are discharged according to the use environment, it is necessary to rapidly exhaust indoor air in preference to heat exchange. However, the heat exchanger (5) can be an obstacle to the flow from the standpoint of the indoor air to be exhausted, thus causing a problem that can not be rapidly exhausted indoor air.

Of course, in this case, the outdoor air as fresh as the exhausted indoor air must be supplied rapidly, and the outdoor air also has to pass through the heat exchanger (5), causing a problem that rapid air supply is impossible.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a heat exchange type ventilation apparatus in which the outdoor air to be supplied and the indoor air to be exhausted exchange heat, rapidly exhausting the pollutant in the room and rapidly removing fresh air. It is to provide a ventilation device that can be supplied quickly.
