At the same time as pressing the rotation guide member 122c is rotated in the rotation guide shaft 122b protruding from the side of the rotation guide hole (121c), the opening and closing plate integrally formed on the rotation guide shaft (122b) ( As the end of the opening and closing plate 122a is rotated in the forward direction and the end of the opening and closing plate 122a is separated from the passage closing protrusion 121b, the flow passage 121a 'of the natural ventilation members 121 and 121' is opened. The motor 123a of 123 is rotated by 90 ° in the set direction so that the opening and closing plate 122a of the dampers 122 and 122 'is kept horizontal in the ventilation body 121a.

When the flow path 121a 'of the natural ventilation members 121 and 121' is opened as the dampers 122 and 122 'are rotated, the motor of the power transmission unit 123 under the control of the controller 140 is opened. Driving the 123a in the reverse direction to rotate the worm gear 123b coupled to the motor 123a shaft in the reverse direction, and the pressing member 123c fixed to the worm gear 123b according to the reverse rotation of the worm gear 123b is It rotates in the reverse direction to maintain the state in close contact with the other side (122c ") of the rotation guide member (122c).

The outdoor air is introduced into the flow path 121a 'opened by the above process through the inlet 112' which is downwardly opened in the cover 112 of the housing 110. The outdoor air is an end portion of the flow path 121a '. Passing through the sensor 150 formed in the interior of the building and at the same time passes through the pre-filter (F).

When outdoor air flows into the flow passage 121a ', the user may adjust the open area of the flow passage 121a', as shown in FIGS. 13 to 15, by a pair of rollers of the manual adjustment unit 124. The roller 124b which protrudes into the guide hole 113 of the housing 110 among the 124b and 124b 'is rotated.

The dampers 122 and 122 'may be rotated by the rollers 124b and 124b' until they are in close contact with the pressing member 123c, and the dampers 122 and 122 are caused by the rollers 124b and 124b '. By controlling the open area of the flow path (121a ') while rotating'), it is possible to reduce the rapid temperature change of the indoor air by blocking the rapid inflow of outdoor air into the flow path (121a ') through the inlet (112').

In addition, the rotation angle of the dampers 122, 122 'is rotated by the motor 123a under the control of the control unit 140 through a carbon dioxide sensor 160, a temperature sensor (not shown), and a detection sensor 150, etc. You can also set the angle to various angles.

As shown in FIG. 16, when the degree of pollution of indoor air measured by the carbon dioxide sensor 160 is not improved during the natural ventilation operation or when forced ventilation by the user is required, as shown in FIG. 17, the controller The forced ventilation unit 130 is operated under the control of the 140, and the motor 123a of the power transmission unit 123 is driven in the reverse direction under the control of the control unit 140 and coupled to the shaft of the motor 123a. The worm gear 123b is rotated in the reverse direction.

At this time, when the pressing member 123c fixed to the worm gear 123b so as to intersect the shaft of the motor 123a rotates in the reverse direction, and the dampers 122 and 122 'maintain the state rotated in the forward direction, When the other side 122c "of the rotation guide member 122c of the dampers 122 and 122 'is immediately pressurized, and the rotation angle of the dampers 122 and 122' is adjusted by the manual adjustment part 124. After the pressing member 123 is rotated by a predetermined angle in the reverse direction, the other side surface 122c ″ of the rotation guide member 122c of the dampers 122 and 122 ′ is pressed.

The pressure member 123c presses the other side 122c "of the rotation guide member 122c of the dampers 122 and 122 ', and at the same time, the rotation guide shaft 122b protrudes from the side. The inside of the rotary guide hole 121c rotates, and the opening and closing plate 122a integrally formed on the rotating guide shaft 122b rotates in the reverse direction and is in close contact with the flow path closing protrusion 121b at the end of the opening and closing plate 122a. The flow passage 121a 'of the ventilation members 121 and 121' is closed, and the motor 123a of the power transmission unit 123 is rotated by 90 ° in the reverse direction in the set state to damper 122 and 122 '. The opening and closing plate 122a to maintain the perpendicular to the ventilation body 121a.

When the flow passage 121a 'is closed by the rotation of the dampers 122 and 122', the motor 123a of the power transmission unit 123 is driven in the forward direction under the control of the controller 140, thereby causing the shaft of the motor 123a to rotate. Rotate the worm gear 123b coupled to the forward direction, the pressing member 123c fixed to the worm gear 123b in accordance with the forward rotation of the worm gear 123b is rotated in the forward direction to the one of the rotation guide member 122c The state in close contact with the side surface 122c 'is maintained.

When the flow passage 121a 'is closed by the dampers 122 and 122', the supply / exhaust fans 133a and 133b of the forced ventilation unit 130 are driven under the control of the controller 140. As the air supply fan 133a rotates, outdoor air flows into the inlet 112 'of the housing 110, and at the same time, foreign matter is filtered out of the filter 134 installed at the front end of the inlet passage 131a.

The filter 134 is a double filtration structure wrapped around the high efficiency filter 134a with the prefilter 134b. The filter 134 may also filter and sterilize yellow dust or fine dust, and the outdoor air passing through the filter 134 may be forced ventilation. The heat transfer element 132 installed at the intersection of the inflow passage 131a and the discharge passage 131b of the member 131 is moved.

In addition, as the exhaust fan 133b rotates, indoor air flows into the front end of the discharge path 131b through the grille (not shown) and moves to the heat transfer element 132, which is discharged from the heat transfer element 132. As the heat exchange between the high temperature indoor air moved to 131b and the low temperature outdoor air flowing into the inlet path 131a is performed, the outdoor air having a low temperature absorbs heat of indoor air having a high temperature, thereby increasing the temperature of the outdoor air. In addition, the indoor air is moved to the rear ends of the inflow passage (131a) and the discharge passage (131b), respectively, with the temperature lowered.

When the temperature of the outdoor air is low and the temperature of the indoor air is high, the description corresponding to the winter time should be described as the low temperature when the outdoor air is high in summer and the indoor air is lower than the temperature of the outdoor air.

Here, the heat transfer element 132 is installed and embedded at a point where the inflow path 131a and the discharge path 131b of the forced ventilation member 131 intersect, and the heat transfer element 132 is embedded The ventilation member 131 is installed in close contact with the side wall of the housing 110 located on the indoor side of the building, and thus is cold because it is kept at a predetermined distance from the side wall of the housing 110 located on the outdoor side. Since the temperature of the hot air is prevented from being directly transmitted to the heat transfer element 132, the heat exchange efficiency may be prevented from dropping rapidly due to the characteristics of the product in which the air supply and the exhaust are simultaneously performed.

The outdoor air moved to the rear end of the inflow path 131a via the heat transfer element 132 is introduced into the room through the detection sensor 150 formed in the flow path 121a 'of the natural ventilation member 121'. At the same time, the indoor air moved to the rear end of the discharge path 131b via the heat transfer element 132 is moved to the flow path 121a 'of the natural ventilation member 121', and the flow path 121a 'is a damper ( Since it is closed by 122, it is discharged to the outside only through the inlet 112 '.

Measuring the flow and pressure of the air passing through the detection sensor 150, and according to the measured results by reducing the rotational speed of the supply and exhaust fans 133a, 133b by the control of the control unit 140 It can also be adjusted.
