By providing the present invention configured as described above, there is an effect of preventing condensation and maintaining ventilation performance at its best by dehumidifying the outdoor air flowing into the room and the indoor air being discharged outdoors through a total heat exchanger.

1 is a conceptual diagram showing a total heat exchanger with a dehumidifying function according to the present invention.
Figure 2 is an exemplary view showing heat loss prevention means applied to a total heat exchanger with a dehumidifying function according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention.

As shown in FIG. 1, the total heat exchanger with a dehumidifying function of the present invention has an outdoor intake port 120, an outdoor exhaust port 130, an indoor exhaust port 140, and an indoor intake port 150 formed around the circumference, respectively, and inside. A case 100 having an accommodation space 110 is provided.

Here, the outdoor intake port 120 and the outdoor exhaust port 130 are preferably formed on one side of the case 100 and on the outdoor side based on a duct connected to the outer wall.

In addition, the indoor intake port 150 and the indoor exhaust port 140 are preferably formed in the indoor case 100 corresponding to the outdoor intake port 120 and the outdoor exhaust port 130.

That is, outdoor air can be introduced into the receiving space 110 of the case 100 through the outdoor intake port 120, and outdoor air can be introduced indoors into the receiving space 110 through the indoor exhaust port 140.

Meanwhile, indoor air can be introduced into the accommodation space 110 of the case 100 through the indoor intake port 150, and the indoor air of the accommodation space 110 can be discharged outdoors through the outdoor exhaust port 130.

At this time, a heat transfer element 300 is provided at the center of the receiving space 110 to exchange heat energy between the inhaled outdoor air and the discharged indoor air.

In addition, a partition is formed inside the accommodation space 110 based on the heating element 300 to divide the space into an outdoor air intake space, an outdoor air exhaust space, an indoor air intake space, and an indoor air exhaust space. desirable.

Therefore, when outdoor air flows into the receiving space 110 through the outdoor intake port 120, it passes through the heating element 300 and then flows into the room through the indoor exhaust port 140, and then flows into the indoor space through the indoor intake port 150. When air flows into the receiving space 110, it passes through the heating element 300 and is discharged outdoors through the outdoor exhaust port 130, thereby heat exchange between indoor air and outdoor air occurs in the heating element 300. .

At this time, a medium filter 310, which is a medium filter containing an antiviral material, is provided on the surface of the heating element 300, which is located in the intake space for outdoor air and the exhaust space for indoor air, to filter the passing air.

In addition, a pre-filter 320 may be further provided on the entire passing surface of the heating element 300.

In addition, the medium filter 310 and the pre-filter 320 are preferably installed in the case 100 in a slip-on, detachable manner.

An intake blower fan 210 is provided on the indoor exhaust port 140 side of the accommodation space 110 to blow outdoor air indoors, and an exhaust blower fan 210 is provided on the indoor air intake vent 150 side of the accommodation space 110 to blow indoor air outdoors. It is preferable that a blowing means 200 including a fan 230 is provided.

Meanwhile, on the side of the outdoor intake port 120 of the accommodation space 110, a first heat dissipation fin 410 that can relatively cool or heat the outdoor air sucked into the accommodation space 110 of the case 100 may be further provided. .

Conversely, on the side of the outdoor exhaust port 130 of the accommodation space 110, a second heat radiation fin 420 may be further provided to relatively cool or heat the indoor air discharged to the outdoors from the accommodation space 110 of the case 100. there is.

In addition, it may include a controller 500 that controls the intake blower fan 210 and the exhaust blower fan 230 according to the user's operation, and the controller 500 controls the first heat dissipation fin 410 and the second heat dissipation fin 420. ) can control the relative cooling and heating operation of indoor/outdoor air.

Meanwhile, between the first heat radiation fin 410 and the second heat radiation fin 420, the temperature of the first heat radiation fin 410 and the second heat radiation fin 420 is reversed due to the Seebeck effect in which the low temperature part and the high temperature part are reversed depending on the direction of electricity supply. It may include a Peltier element 430.

According to FIG. 2, the Peltier element 430 is a device that can generate the Peltier effect. The Peltier effect is a phenomenon in which when a potential difference is applied to both sides of an object, heat flows along with the current, creating a temperature difference at both ends, In other words, when an electric current flows, a temperature difference occurs, causing one side to heat and the other side to cool.
A product that utilizes this effect is a Peltier element or thermoelectric element. If the high-temperature part on the other side that requires low-temperature cooling is forcibly cooled, the heat from the low-temperature part is transferred to the high-temperature side. Due to the Seebeck effect, when one side becomes cold, the other side becomes hot. Efficiency improves only when the hot side is well cooled. If overheated, efficiency decreases and eventually the device may be destroyed.[2] A thermal reversal phenomenon may occur, causing the low-temperature section and the high-temperature section to be reversed.

On the contrary, the effect of generating electromotive force when a temperature difference is applied to both ends is called the Seebeck effect. These two effects are collectively called the Seebeck-Peltier effect, and since it is an effect in which heat and electricity change with each other, it is called the thermoelectric effect.

That is, when cooling heat is generated in the first heat dissipation fin 410, heat is generated in the second heat dissipation fin 420 due to the Peltier effect. Conversely, if heat is generated in the first heat dissipation fin 410, heat is generated in the second heat dissipation fin 420 due to the Peltier effect. 420), cooling heat may be generated.

Meanwhile, by controlling the direction of energization of the Peltier element 430 under the control of the controller 500, the Seebeck effect, in which the low-temperature section and the high-temperature section are reversed, is used to cool the first heat dissipation fin 410 located at the outdoor intake port 120 in the summer. The incoming outdoor air is cooled to remove moisture from the heating element 300, and the moisture in the indoor air can be discharged to the outdoors by generating heat from the second heat dissipation fin 420 located in the outdoor exhaust port 130.
