The first heat exchanger is located in the middle part of the first pipe, which raises or lowers the temperature of the entrance air according to the indoor temperature. The first heat exchanger has a radiator shape and a moisture adsorbent is attached thereto.

The outside air in summer is hot and humid, and moisture contained in the air is collected by the moisture absorbent and the radiator in the process of entering the room through the first pipe. In order to remove the collected moisture, the functions of the first heat exchanger and the second heat exchanger are periodically changed. The first heat exchanger dissipates heat by a variable action of a heat pump to be described later, and moisture is evaporated by the dissipated heat. The evaporated moisture is discharged to the outside through the second pipe.

The first pipe and the second pipe are controlled by a plurality of dampers to be described later.

Specifically, stainless steel pipes, copper pipes, etc. can be used, and pipes of a material equivalent thereto can be used. The heat transfer plate may have high heat conduction efficiency by contacting the heat medium flow tube.

When the heat medium flow pipe is located over the entire cross-sectional area of the first pipe, and a moisture adsorbent is located in the heat medium flow pipe, the air flowing through the first and second pipes causes pressure and wind speed loss by the first and second heat exchangers. To prevent this, the moisture absorbent may be attached only to the outer surface of the heat medium flow pipe. However, this causes another problem that the dehumidification efficiency is lowered. Therefore, it is preferable that a plurality of first heat exchangers are installed. When a plurality of heat exchangers are installed, different heat can be maintained step by step to adsorb moisture or generate heat step by step.

In place of the first heat exchanger and the second heat exchanger, a heating device is mounted to generate heat by an external power source, which easily controls the amount of heat generated and has an effect of reducing cost. In addition, indoor water supply pipes can be installed. The indoor water supply pipe maintains a constant room temperature, and water can be circulated into the first and second heat exchangers when necessary by a temperature sensor. In addition, the building is heated by a boiler, and the heating heat heated by the boiler can be utilized. The heating heat may use the heat of the front and rear ends of the distributor. A hot water pipe can be used in place of the heating water. If necessary, the boiler is operated, and the heated hot water can be used for the first and second heat exchangers.

And a third damper is positioned at the third opening, and the fourth opening and the second opening form a flange 265 to be coupled to a part of the enclosure.

The present invention (Examples 5-1 to 5-11) is the invention for the first to fourth turning devices. The enclosure of the present invention has two pipelines (a first pipeline and a second pipeline). In the first enclosure, outdoor air enters the room, and a first direction changer is located at a front end of the first heat exchanger, and a second direction changer is located at a rear end. The second enclosure discharges indoor air to the outdoors. A third direction converter is located at the front end of the second heat exchanger, and a fourth direction converter is located at the rear end.

Air is introduced to one side of the first to fourth direction converters, and air is discharged to the remaining three sides. Air discharge may be discharged in one direction, or air may be discharged in two or more directions.

To implement this, three dampers are combined. A second damper is positioned above the direction changer, and a third damper is positioned below it. The second and third dampers are located in parallel. The first damper is positioned diagonally or at right angles between the second and third dampers. The first damper is located in the entire cross section of the first pipe or the second pipe. That is, four second dampers are located in the upper part of the enclosure, and four third dampers are located in the lower part. A third conduit is formed by attaching an additional box in the form of a box to form a flow path by four dampers on the upper part of the enclosure. On the other hand, a fourth pipe is formed by attaching an additional box in the form of a box under the enclosure.

The first to third dampers form a plurality of damper plates, and the damper plates are simultaneously operated to open or close the pipeline. In addition, by adjusting the opening and closing angle of the damper plate, it is possible to control the air flow rate. Additionally, when the first damper is formed of a diagonal line, a plurality of damper plates may be operated simultaneously, or may be partially operated. When partially operated, it is to induce the flow of air in two or more directions. In the case of the first damper, the air must be flowed by branching in a straight line and up/down side as needed. To implement this, two dampers may be combined to implement a first damper.

The damper plate has a plate shape, a heat insulating layer 564 accommodated in the first to third dampers, the damper plate has a plate shape, and a step 565 protruding from both ends of the first to third dampers is formed in the step. Includes a sealing 566. This is to block the heat conduction as well as the flow of air in the condition where the damper is closed. Particularly, the damper plate and the contact portion of the damper plate are provided with a step and a seal to realize complete air blocking.

In order to improve the assembling property of the ventilation device, the first to fourth directional electric limiters are formed in one damper case, which can be used as a part of the enclosure. That is, the first, second, and third dampers may be accommodated in the damper case and assembled as a part of the enclosure. Specifically, the damper case is a plate whose both sides are sealed, and four sides have openings. A second damper is mounted on the upper opening, and a third damper is mounted on the lower opening. One of the side openings is an opening through which air is introduced, and a first damper is positioned on the corresponding surface. The damper case can be optionally assembled with the enclosure.

Four directional converters consisting of a combination of the first, second, and third dampers presented above, two first and second pipes in a straight direction, the third and fourth pipes that communicate the first and second pipes with each other, the first And operations of the first and second heat exchangers accommodated in the second pipe are controlled by the controller. By operating the controller, a plurality of control modes can be implemented.

The first mode (indoor/outdoor exchange mode) discharges indoor air to the outside and supplies outdoor air to the inside. This allows the indoor air to be quickly discharged to fresh air.

The second mode (cooling, heating and indoor/outdoor exchange) operates in the same manner as in the first mode, and additionally, a low or high temperature is applied through the first and second heat exchanger refrigerants to control the temperature of the air entering the room.

In the third mode (summer recirculation and partial outdoor air), the air discharged from the room enters the room again. On the other hand, air supplied from the outdoors is discharged back to the outdoors. Accordingly, indoor air and outdoor air pass through the first and second heat exchangers. The air entering the room is cooled down by the heat exchanger. At this time, the first dampers of the first and third direction converters are partially opened to allow a part of the outdoor air to enter the room and discharge a part of the indoor air to the outside.

The fourth mode (rehumidifying cooling in summer) is the same as the third mode, but the first dampers of the first and third directional converters are closed so that indoor air is completely re-inflowed and outdoor air is discharged. In this process, the moisture absorbent of the heat exchanger adsorbs indoor moisture. The third direction changer of the fourth mode changes the damper, and the functions of the first heat exchanger and the second heat exchanger change at the same time. Therefore, the moisture collected in the heat exchanger can be evaporated and discharged to the outside.

The fifth mode (winter recirculation and partial outdoor air) and the sixth mode (winter humidification and heating) operate similarly to the third and fourth modes, but operate in reverse. Therefore, it has the effect of enabling heating of indoor air, enabling partial outdoor air, and humidifying the interior by using external moisture.
