Description

Wall-installable heat recovery type ventilation device

The present invention relates to a heat recovery ventilator capable of installing a wall surface having excellent space utilization and convenient maintenance by constructing a heat recovery ventilation device having a structure that facilitates wall-mounting construction in an apartment house or the like.

In general, the heat recovery ventilator is a device for ventilating indoor air while minimizing heat loss by allowing heat to be supplied to the room after heat exchange between indoor air exhausted outdoors and outdoor air supplied to the room.

The heat recovery ventilator is divided into an air supply unit and an exhaust unit, a heat exchange element is installed at a center where the air supply unit and the exhaust unit intersect, and a blower fan is provided on the air supply unit and the exhaust unit side to provide a blowing force. It is configured by.

In such a heat recovery ventilator, when circulating indoor and outdoor air to reduce heating and cooling energy in winter or summer, it is preferable to recover energy through a heat exchanger by allowing indoor ventilation and outdoor air to flow through the heat exchanger. However, in the case of summer in the summer season or the summer season, ventilation through the heat exchanger and heat exchange between the outside air may not be necessary.

Therefore, when heat exchange is not required, a bypass function is required to allow ventilation and outside air to pass through the heat exchange element assembly without passing through the heat exchange element.

In order to solve the above problems, in Korean Patent Publication No. 10-2008-0001312, the bypass device is mounted on the outer circumferential surface of the main body so that the air in the main body does not pass through the heat exchange element and the air supply and exhaust parts are connected to each other. Disclosed is a heat recovery type ventilation device having a bypass device configured to be attached.

In Korean Patent Publication No. 10-1279997, bypass duct connectors are provided at exhaust inlets and exhaust outlets formed in opposite directions on both sides of the body, respectively, and the bypass duct connectors installed at the exhaust outlets are exposed to the outside through the upper surface of the body. Installed to be exposed, a bypass duct having a predetermined shape is detachably installed between the two bypass duct connectors from the outside of the main body, and the flow of air discharged from the room to the outside between the exhaust intake port and the bypass duct connector Disclosed is a heat-recovery ventilation device that is provided with an exhaust channel switching means that transfers the direction to a heat exchanger or a bypass duct side in response to an output signal from the control unit.

However, most of the heat recovery type ventilation devices of the conventional configuration are difficult to install during installation due to being installed for ceiling use, and if the casing becomes larger due to the addition of the bypass function or is added as a separate configuration to the outside, the installation space is secured. There are a lot of space limitations as it should be, and there is a problem in that it is difficult to maintain due to the fact that it is installed at the ceiling or does not know at all even though it is necessary to replace and replace the heat exchange element, which is a consumable product.

The bypass flow path 50 is partitioned between the upper side of the ventilation chamber 41 and the main body 10 to communicate with the external air chamber 31 and the air supply chamber 32.

The damper unit 60 is opened and closed between the heat exchange element 20 and the outside mechanism 12 in the outside air chamber 31 and the first damper 61 installed to control the flow of the outside air through the heat exchange element 20. , A second damper 62 installed to control the bypass of the outside air by opening and closing between the outside air chamber 31 and the air supply chamber 32, and the indoor air by opening and closing the air between the ventilation chamber 41 and the air supply chamber 32 It is composed of a third damper 63 is installed to clean the. The damper unit 60 is formed of a rotating gate 60a to open and close the flow path, and a driving motor is installed for each damper for opening and closing operation of the rotating gate 60a. Accordingly, according to the opening and closing operation of the damper unit 60, it is possible to selectively use the heat exchange mode, the bypass mode, and the indoor air clean mode.

The cleaning means 70 is provided with a first clean filter 71 installed between the outer mechanism 12 and the first damper 61 in the outer air chamber 31, and a supply mechanism 11 and the first air supply chamber 32. It is composed of a second clean filter 72 installed between the two dampers 62 and the third damper 63.

The first clean filter 71 cleans the outside air supplied to the heat exchange element 20, and the second clean filter 72 cleans the outside air that is bypassed and cleans the indoor air.

On the other hand, in the main body 10, each chamber is divided around the heat exchange element 20, and the lower part of the air supply chamber 32 and the side part of the exhaust chamber 42 are divided into PCB substrates, sensors, and power supplies for controlling devices. The control unit 80 is configured.

Hereinafter, according to the action of the heat recovery ventilator capable of installing a wall surface of the present invention, the heat recovery ventilator capable of wall mounting according to the present invention is constructed to be attached to a wall according to a structure that facilitates wall construction.

When using the heat exchange mode, as shown in FIG. 3, the first damper 61 is opened, the second damper 62 and the third damper 63 are closed, and the air supply fan 33 and the exhaust fan 43 are It is controlled to be in an operating state. Accordingly, the outdoor air supply air flowing into the external mechanism 12 and the indoor exhaust air flowing into the ventilation port 14 cross-heat through the heat exchange element 20 so that heat is exchanged, so that the air supply air flows through the air supply port 11. It is supplied to the room through, and the exhaust air is discharged to the room through the exhaust port (13).

At this time, the outdoor air supply air supplies clean air filtered through the first clean filter 71 before passing through the heat exchange element 20. Therefore, it is possible to maintain adequate ventilation and temperature and humidity in the room while preventing excessive energy consumption in summer / winter.

When using the bypass mode, as shown in FIG. 4, the second damper 62 is opened, the first damper 61 and the third damper 63 are closed, the air supply fan 33 is operated, and the exhaust fan (43) is controlled in an inoperative state. Accordingly, the outdoor air supply air flowing into the external device 12 is bypassed from the external air chamber 31 to the air supply chamber 32 communicating with the second damper 62, and the air is supplied to the room through the air supply port 11. In the process of bypassing the supply air, clean air filtered through the second clean filter 72 is supplied to the room. Therefore, when the indoor temperature, such as spring / autumn, is higher than the outdoor, by bypassing the outdoor air lower than the indoor temperature to the indoor, it is necessary to maintain a pleasant environment and to eliminate the need for a separate cooling device, thereby reducing power consumption. .

When the heat exchange mode or the bypass mode is unnecessary, the indoor air clean mode can be used to recirculate the indoor air.

In the indoor air clean mode, as shown in FIG. 5, the third damper 63 is opened, the first damper 61 and the second damper 62 are closed, the air supply fan 33 is operated, and the exhaust fan (43) is controlled in an inoperative state. Accordingly, the indoor air flowing through the ventilation hole 14 is re-supplied to the air supply chamber 32 communicating through the third damper 63 while being filtered by the second clean filter 72 to supply clean air again. (11). As such, when the heat exchange mode or the bypass mode is not used, the indoor air is circulated to provide an air cleaning effect.

6 is an exemplary view showing the configuration of the induction plate formed in the front of the heat exchange element in the rotation gate and the supply chamber constituting the first damper according to the present invention.

The pivoting gate 61a constituting the first damper 61 may be formed such that the rear end (right in the drawing) is rotated on the axis of the drive motor at a position adjacent to the inner wall of the housing 10a. In this case, when the pivoting gate 61a is opened, it is opened while pivoting toward the outside air chamber 31 formed below the axis. At this time, the rotation gate 61a is formed to maintain a downwardly inclined state toward the outside air chamber 31 formed at the bottom in the fully open state, thereby allowing the outdoor air introduced through the outside mechanism 12 to have a gentle air supply flow path 30. It can be formed and can be supplied to the total heat exchanger (20). Here, it is natural that the inclination angle of the pivot gate 61a can be formed by calculating an angle that allows the inflowing outdoor air to flow in an optimal state.

In the above configuration, a support (61c) for supporting the pivot gate (61a) is formed. The support (61c) is protruding to a certain height on the inner wall surface of the housing (10a) when the pivoting gate (61a) is opened, while supporting the pivoting gate (60a) at the end while maintaining an optimal angle to support it so that it no longer rotates Plays a role. According to this configuration, the rotating gate 61a can always be opened at an optimum angle despite the operating error of the driving motor.

A flow path groove 61b is formed on an upper surface of the rotation gate 61a. The flow path groove 61b is a groove formed toward the end from the middle point of the pivot gate 61a, and is formed in a concave arc shape, and is formed to be linearly wider toward the end from the starting point. The flow path groove (61b) is to help the friction and pressure difference between the point where the flow path groove is not formed to spread the outdoor air evenly and flow into the heat exchanger (20). Accordingly, it is possible to increase the speed or amount of the heat exchanger 20 passing through the outdoor air.

Here, an induction plate 64 is formed in front of the heat exchange element 20 in the air supply chamber 32. The guide plate 64 is fixed to the bottom of the air supply chamber 32 and is installed to be resiliently rotated by a spring, or is formed to have its own elasticity, such as a rubber plate, so that it is erected normally and is fixed when external force is applied. It is formed in a structure that can rotate about. According to this, when the air supply fan 33 is operated, the air induction plate 64 is rotated by the pressure of the outdoor air passing through the heat exchange element 20, and air supply is possible, and when the exhaust fan 43 is operated, the air induction plate is operated. Since the (64) blocks the front of the heat exchange element 20, it is possible to prevent the reverse operation and reverse flow of the air supply fan (33).

At least one flow path 65 may be formed on a surface of the induction plate 64 facing the heat exchange element 20. The outdoor air flowing through the air supply passage (30) passes through the flow path (65). Thus, the outdoor air passing through the euro pipe 65 is faster than the outdoor air that does not pass. Therefore, it is possible to increase the overall flow velocity while the fast flow attracts the slow flow, thereby enabling rapid air supply. Furthermore, a force is applied to determine the angle of the guide plate 64 in a direction toward the outdoor air discharged through the euro pipe 65. According to the euro pipe 65 as described above, the guide plate 64 is predetermined. Not only is it easy to rotate at an angle of, but also it is possible to stably maintain the angle without fluttering easily even with a slight pressure change of the outdoor air applied to the whole. Accordingly, by preventing excessive movement of the guide plate 64 due to the pressure change applied from the outdoor air that has passed through the heat exchange element 20, the outdoor air is stably guided by noise or noise caused by the movement of the guide plate 64. It is possible to reduce the occurrence of vibration.

On the other hand, it is preferable that the flow path 65 has a shape in which the inlet is wide and the diameter becomes narrower toward the outlet, based on the flow direction of outdoor air. Through this, it is possible to increase the speed of the outdoor air passing through the euro pipe 65, and the guide plate 64 may help stable operation.

As described above, in the detailed description of the present invention, the most preferred embodiments of the present invention have been described, but various modifications can be made within the scope of the technical scope of the present invention, and thus the protection scope of the present invention is described above. It is not limited to the examples, but the scope of protection should be recognized from the technologies described in the claims to be described later and from these technologies to equivalent technical means.
