The present invention relates to an electrothermal heat exchange ventilation system, and more particularly, to install an electrothermal heat exchanger for mutual heat exchange between indoor air discharged to the outside and outdoor air taken in from the outside in a ventilation system configured for indoor ventilation. In addition, the high efficiency for the final filtering of the first and second air mixing unit and the contaminants in the mixed air, which is a thermal equilibrium space that can exchange heat by mutually mixing the indoor air re-intake from the room and fresh outdoor air taken in from the outside The filter is installed between the heat exchanger and the indoor blower fan, so that the first and the second heat exchange action between the indoor air re-suctioned from the room and the outdoor air sucked from the outside through the heat exchanger having a diagonal flow path. Fresh air intakes from indoor and outdoor air re-inhaled through air mixing unit Thermal equilibrium according to the 2nd and 3rd heat exchange between the air enables the air supply to the room to be minimized, that is, the temperature change is minimized, and the filter is filtered by the high efficiency filter. The present invention relates to a total heat exchange ventilation system capable of creating a comfortable indoor environment by continuously supplying mixed air to a room.

In general, human dwelling space tends to be increasingly airtight and insulated due to energy conservation and noise, and thus the indoor air of the closed space gradually changes to carbon dioxide over time. Because the pollutants interfere with the breathing of living things, the space where many people, such as offices, should be ventilated from time to time.

At this time, while maintaining indoor air, indoor air is discharged to the outside and outdoor air is supplied to the room so that the room can always achieve a comfortable state. The ventilation device using the heat exchanger method is used. same.

In the case of the ventilation apparatus using the conventional total heat exchanger method, as shown in FIG. 1, the interior side of the case 110 includes an external air discharge port 112 for supplying external air to the interior and an indoor air suction port 113 for sucking indoor air. Is installed, and the outdoor side is provided with an outside air inlet 111 through which fresh outside air is introduced and an indoor air exhaust port 114 for discharging the contaminated indoor air to the outside, and horizontally in the center of the case 110. The total heat exchanger 120 is provided in the direction.

In addition, an intake fan 115 and an exhaust fan 116 are respectively provided in the external air discharge port 112 and the indoor air exhaust port 114.

In addition, the heat exchanger 120 is a member that can be inserted or removed by the handle 122 in the hole formed in the center of the case 10, the base surface (not shown) and the uneven surface (not shown) A plurality of heat transfer plate bodies are continuously stacked, but the flow paths (not shown) of the uneven surface are stacked in the frame 121 so as to be orthogonal to each other, and a filter for purifying the air flowing into both sides of the heat exchanger 120. 124 is installed.

Therefore, the heat exchanger 120 in which the plurality of heat transfer plates are stacked as described above is formed with flow paths perpendicular to each other on one side and the other side, so that indoor air passes through the flow path on one side and outdoor air passes through the flow path on the other side. While the heat exchange between each other and the outdoor air is supplied to the room through the external air discharge port 112, the indoor air is discharged to the outside through the indoor air exhaust port 114 is made to ventilate the room.

However, in the case of the conventional ventilation device is sucked into the case 110 through the external air inlet 111 and the indoor air inlet 113 in accordance with the driving of the intake fan 115 and the exhaust fan 116, the heat exchanger 120 Immediately after the first heat exchange at the outside air discharge port 112 and the indoor air exhaust port 114 through the outdoor heat exchanged with the structure of the outdoor air and the indoor air discharged only in the case 110 Air mixing member or air mixing space for secondary heat exchange between the outdoor air and indoor air supplied through heat exchanger 120 in the case 110, that is, the heat exchanger in the case 110 to achieve thermal equilibrium. Since there is no such structure, even though the indoor air and the outdoor air are primarily heat exchanged through the heat exchanger 120 as described above, the external air outlet There was a big problem such that the temperature difference between the outdoor air and the room temperature supplied to the room through the 112 can not maintain a comfortable indoor environment.

In addition, when the outdoor air is continuously supplied to a room by operating a conventional ventilation device, the indoor air is not maintained at a constant temperature due to the supplied outdoor air, thereby increasing or decreasing the temperature. In order to maintain the change at a constant temperature, there was also a problem such as the need to operate a separate heater or air conditioner, resulting in power loss.

In the case of the conventional ventilation device, before the heat exchange action is performed between the indoor air and the outdoor air using the heat exchanger 120, the pollutant contained in the outdoor air through the filter 124 installed on one side of the heat exchanger 120. It is composed of only the primary filtering operation to remove them, but the residual amount of contamination because it is difficult to completely remove the contaminants contained in the outdoor air with only the primary filtering performed on the heat exchanger 120 side. As outdoor air is supplied to the room in a state in which materials are contained, there are problems such as deterioration of cleanliness of indoor air and difficulty in creating a comfortable indoor environment compared to outdoor air supplied through a second filtering operation.

Maintain a comfortable indoor environment at all times by continuously supplying fresh outdoor air while minimizing the temperature change of the room by the electrothermal heat exchange ventilation system (1) of the present invention, such as supplying air into the room. You can do it.

As described above, the above-described embodiments are described with reference to the most preferred examples of the present invention, but are not limited to the above embodiments, and it will be apparent to those skilled in the art that various modifications can be made without departing from the technical spirit of the present invention. .

The electrothermal heat exchange ventilation system of the present invention has a diagonal flow path by installing an electrothermal heat exchanger for mutual heat exchange between indoor air discharged to the outside and outdoor air taken in from the outside in a ventilation system configured for indoor ventilation. Through the heat exchanger, the indoor air re-absorbed from the room and the outdoor air taken in from the outside through the heat exchange mutually exchanging heat, that is, it can be supplied with a minimum temperature change.

In addition, in the present invention, between the heat exchanger and the indoor blower fan, the first and second air mixing units which are thermal equilibrium spaces capable of performing heat exchange by mutually mixing indoor air re-inhaled from the inside and fresh outdoor air taken in from the outside; By installing a high-efficiency filter for the final filtering of contaminants in the mixed air, it minimizes the thermal change, that is, the temperature change of the air supplied to the room, and also keeps the fresh outdoor air on the re-inhaled indoor air side. In addition, by improving the cleanliness of the muddy indoor air by supplying, through the final filtering operation by the high-efficiency filter, by continuously supplying the mixed air to the room in a clean state, it is also possible to maintain a pleasant indoor environment at all times. have.

In the case of the present invention, the first and second air mixtures are supplied through heat exchange with the indoor air discharged to the outside through the total heat exchanger in supplying the fresh outdoor air to the first and second air mixing units in which the indoor air is re-inhaled. When supplying the mixed air in the air mixing unit indoors, there is almost no temperature difference with the room temperature, so the continuous supply of the outdoor air does not require the operation of a separate heating device or cooling device for maintaining the indoor temperature. Energy savings can also be achieved.
