Description

TECHNICAL FIELD

The present invention relates to a heat exchange ventilating apparatus, and more particularly, to a heat exchange ventilating apparatus allowing for the enhancement of air intake/exhaust efficiency by preventing the loss of air flow during air intake/exhaust.

BACKGROUND ART

A heat exchange ventilating apparatus is used as a part of a building's air conditioning system. While discharging indoor air to the outside of a room and drawing outdoor air into the room in order to ventilate the building, the heat exchange ventilating apparatus is capable of reducing heat loss by allowing for an exchange of heat between indoor and outdoor air.

In general, a heat exchange ventilating apparatus includes a total heat exchange element and a blower fan for the intake and discharge of indoor and outdoor air, and allows for the exchange of heat between the indoor and outdoor air passing through the total heat exchange element without commingling of the airstreams. The heat exchange ventilating apparatus may have inside and outside inlets and inside and outside outlets formed therein, thereby causing outdoor air to be drawn indoors while concurrently causing indoor air to be discharged outdoors.

In a heat exchange ventilating apparatus according to the related art, a path through which outdoor air drawn indoors passes and a path through which indoor air discharged outdoors passes are formed to intersect each other, and a laminated and fixed-type heat exchange element is included at the intersecting area for the exchange of heat.

Since the performance of a heat exchange ventilating apparatus is determined according to air intake/discharge ability, studies regarding the enhancement of air intake/discharge ability have been continuously undertaken.

Also, in the case of introducing and exhausting air through the use of an apparatus such as a heat exchange ventilating apparatus in which outdoor air is drawn indoors and is then discharged outdoors again, it is common to install a separate intake duct and a separate exhaust duct. Accordingly, in order to install the separate intake duct and the separate exhaust duct, multiple duct passages such as through-holes in a wall need to be provided in a wall.

BEST MODE

Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view illustrating a configuration of a heat exchange ventilating apparatus according to an exemplary embodiment of the present invention.

Referring to FIG. 1, a ventilating apparatus 100 for total heat exchange (hereinafter, also referred to as a “total heat exchange ventilating apparatus”) according to an exemplary embodiment of the invention includes a body housing 110, a first blower fan 121, a second blower fan 122, a rotary-type total heat exchange element 130, a first covering 140, a filter box 150, and a pre-filter 153.

The body housing 110 may have an inside inlet 111, an inside outlet 112, an outside inlet 113, and an outside outlet 114 formed therein. The total heat exchange ventilating apparatus 100 may draw indoor air in through the inside inlet 111 and discharge the indrawn air outdoors through the outside outlet 114. Also, the total heat exchange ventilating apparatus 100 may draw outdoor air in through the outside inlet 113 and discharge the indrawn air indoors through the inside outlet 112.

In the present embodiment, the body housing 110 may be divided into an upper body housing 110a and a lower body housing 110b. The upper body housing 110a is disposed in the direction of indoors and the lower body housing 110b is disposed in the direction of outdoors. The inside inlet 111 and the inside outlet 112 may be formed in the upper body housing 110a, and the outside inlet 113 and the outside outlet 114 may be formed in the lower body housing 110b.

According to this embodiment, the inside inlet 111 may be formed toward one side of the body housing 110 and the inside outlet 112 may be formed toward the other side of the body housing 110. One and the other sides of the body housing 110 may be opposed to each other. When the inside inlet 111 and the inside outlet 112 are opposed to each other, outdoor fresh air drawn in through the outside inlet 113 and inside outlet 112 may be prevented from being immediately discharged through the inside inlet 111 and the outside outlet 114.

The body housing 110 may have first and second air flow paths formed therein. The first air flow path may be formed between the inside inlet 111 and the outside outlet 114 and the second air flow path may be formed between the outside inlet 113 and the inside outlet 112.

The first and second blower fans 121 and 122 may be disposed in the first air flow path formed between the inside inlet 111 and the outside outlet 114 and the second air flow path formed between the outside inlet 113 and the inside outlet 112, respectively. According to this embodiment, the first blower fan 121 may draw indoor air in through the inside inlet 111 and the first air flow path and discharge the indrawn air through the outside outlet 114. The second blower fan 122 may draw outdoor air in through the outside inlet 113 and discharge the indrawn air through the second air flow path and the inside outlet 112.

The rotary-type total heat exchange element 130 includes a first area and a second area and allows the first air flow path to pass through the first area and the second air flow path to pass through the second area thereof.

In this embodiment, the rotary-type total heat exchange element 130 in the shape of disc is disposed perpendicular to the direction of the air flowing in the first and second air flow paths.

The indoor air drawn in through the inside inlet 111 may be allowed to pass through the first area of the rotary-type total heat exchange element 130, and the outdoor air drawn in through the outside inlet 113 may be allowed to pass through the second area thereof. The rotary-type total heat exchange element 130 may retain sensible and latent heat included in the indoor air drawn in through the inside inlet 111 by its rotary motion, and transfer the retained sensible and latent heat to the outdoor air drawn in through the outside inlet 113. Since the sensible and latent heat included in the indoor air is transferred to the air drawn from outdoors by the rotary-type total heat exchange element 130, the air discharged from the inside outlet 112 may have sensible and latent heat closer to that of the indoor air rather than that of the outdoor air.

In the present embodiment, the rotary-type total heat exchange element 130 may have a flat disc shape. The indrawn outdoor air and indoor air may be allowed to pass through the upper and lower surfaces of the total heat exchange element 130. Here, when the disc-type rotary-type total heat exchange element 130 is rotated around the central axis thereof, the sensible and latent heat of the indoor air passing through the disc-type rotary-type total heat exchange element 130 may be transferred to the outdoor air passing therethrough. The rotary-type total heat exchange element 130 may be formed to have a plurality of layers. By additionally including the plurality of layers formed of loess components, bamboo fiber, charcoal, or the like, the antibacterial and deodorization function thereof may be enhanced with respect to the air passing through the rotary-type total heat exchange element 130.

The first covering 140 may be connected to the first blower fan 121 and constitute a part of first air flow path. In this embodiment, the first covering 140 may have one open side 141 connected to an intake part of the first blower fan 121 and the other open side 142 connected to the first area through which the first air flow path of the rotary-type total heat exchange element 130 passes. The first covering 140 may have dimensions such that it is narrowed according to air flow direction in the first air flow path. That is, the dimensions may be such that the other open side 142 of the first covering 140 may be formed to be wider than one side 141. As described in the present embodiment, when the first covering 140 has the dimensions such that it is gradually narrowed according to air flow direction, the intake efficiency may be enhanced with respect to the indoor air flowing in the first air flow path.

The filter box 150 may be connected to the first covering 140 and constitute a part of first air flow path.

In this embodiment, the filter box 150 may have one open side 151 facing the other open side 142 of the first covering 140 and connected to the first area through which the first air flow path of the rotary-type total heat exchange element 130 passes and the other open side connected to the inside inlet 111.

One side 151 of the filter box 150 may have dimensions corresponding to those of the other open side 142 of the first covering 140 and contact the other open side 142 of the first covering 140, thereby forming a single air flow path.

Also, the filter box 150 has dimensions widened according to the direction of air flowing in the first air flow path.

In the present embodiment, the rotary-type total heat exchange element 130 may be disposed between one side 151 of the filter box 150 and the other open side 142 of the first covering 140.

Accordingly, the first air flow path is formed such that the air flowing therein sequentially passes through the inside inlet 111, the filter box 140, the rotary-type total heat exchange element 130, the first covering 140, the first blower fan 121 and the outside outlet 112.

Meanwhile, the sections of the other open side 142 of the first covering 140 and one side 151 of the filter box 150 in contact with the disc-type rotary-type total heat exchange element 130 may have a semi-circular shape. The sections of the other open side 142 of the first covering 140 and one side 151 of the filter box 150 having the semi-circular shape may cover a part of the disc-type rotary-type total heat exchange element 130. As described in the present embodiment, when one side 151 of the filter box 150 and the other open side 142 of the first covering 140 is shaped to conform to the shape of the rotary-type total heat exchange element 130, the leakage of indoor air flowing in the first air flow path formed of the filter box 150 and the first covering 140 may be reduced.

The pre-filter 153 may be installed in the open other side 152 of the filter box 150. The pre-filter 153 filters the indoor air drawn in through the inside inlet 111 to thereby remove foreign objects included in the indoor air. The pre-filter 153 may prevent the rotary-type total heat exchange element 130 from being contaminated by the foreign objects included in the indoor air.

The total heat exchange ventilating apparatus 100 according to this embodiment may further include a second covering 160 disposed between the second blower fan 122 and the rotary-type total heat exchange element 130.

The second covering 160 may prevent the leakage of air in the second air flow path formed between the outside inlet 113 and the inside outlet 112. The second covering 160 may have one side 161 having an opening and connected to an exhaust part of the second blower fan 122 and the other side 162 contacting the rotary-type total heat exchange element 130.

Accordingly, the second air flow path is formed such that the air flowing therein sequentially passes through the outside inlet 113, the second blower fan 122, the second covering 160, the rotary-type total heat exchange element 130, and the inside outlet 112.

Meanwhile, The section of the other side 162 of the second covering 160 in contact with the rotary-type total heat exchange element 130 may have a semi-circular shape. The section of the other side 162 of the second covering 160 having the semi-circular shape may cover a part of the disc-type rotary-type total heat exchange element 130, thereby reducing the leakage of indoor air flowing in the second air flow path formed of the second covering 160.

The total heat exchange ventilating apparatus 100 according to this embodiment may further include at least one purification filters 170 disposed inside the second covering 160. The purification filters 170 filter the air drawn from outdoors through the second blower fan 122. The at least one purification filters 170 may include known filter components such as nano silver coating, charcoal components, bamboo components, or the like.

The total heat exchange ventilating apparatus 100 according to this embodiment may further include a shielding part 180 encompassing the peripheral area of the rotary-type total heat exchange element 130. The shielding part 180 may prevent outdoor and indoor air from being commingled and contaminated during total heat exchange in the rotary-type total heat exchange element 130. In this embodiment, the shielding part 180 may have a dual structure.

FIGS. 2 (a) through 2(c) illustrate a first covering, a filter box and a second covering used in a heat exchange ventilating apparatus according to another exemplary embodiment of the present invention.

Referring to FIG. 2 (a), a first covering 240 may constitute a part of first air flow path expelling the indoor air outdoors by being formed between an inside inlet and an outside outlet of a body housing. The first covering 240 may have one side connected to an intake part of a first blower fan 221 and the other side having an opening. The first covering 240 may have dimensions such that it is narrowed according to the air flow direction in the first air flow path. That is, the dimensions may be such that the other side of the first covering 240 may be formed to be wider than one side. As described in the present embodiment, when the first covering 240 has dimensions such that it is gradually narrowed according to air flow direction, intake efficiency may be enhanced with respect to the indoor air flowing in the first air flow path.

Referring to FIG. 2 (b), a filter box 250 may constitute a part of first air flow path connected to the first covering 240. In this embodiment, the filter box 250 may have one side opposed to the other side of the first covering 240 and the other side having an opening. One side of the filter box 250 may have dimensions corresponding to those of the other side of the first covering 240.

In the present embodiment, a rotary-type total heat exchange element may be disposed between one side of the filter box 250 and the other side of the first covering 240. In this case, the other side of the first covering 240 and one side of the filter box 250 may have a section thereof corresponding to the shape of the rotary-type total heat exchange element. As described in the present embodiment, when one side of the filter box 250 and the other side of the first covering 240 is shaped to conform to the shape of the rotary-type total heat exchange element, the leakage of indoor air flowing in the first air flow path formed of the filter box 250 and the first covering 240 may be reduced.

Referring to FIG. 2 (c), a second covering 260 may constitute a part of second air flow path drawn outdoor air in and transferring the indrawn air indoors. The second covering 260 may have one side having an opening and connected to an exhaust part of a second blower fan (not shown) drawing the outdoor air in. The other side of the second covering 260 may contact a rotary-type total heat exchange element (not shown). The second covering 260 may prevent the leakage of air in the second air flow path.

FIG. 3 illustrates a configuration of a heat exchange ventilating apparatus according to another exemplary embodiment of the present invention. Referring to FIG. 3, a ventilating apparatus 100′ for total heat exchange according to this embodiment may further include an intake/exhaust duct 101 as compared with the ventilating apparatus 100 for total heat exchange of FIG. 1. Since the elements other than the intake/exhaust duct 101 are identical to those described in the aforementioned embodiment, a detailed description thereof will be omitted. Rather, the intake/exhaust duct 101 will be described in detail with reference to FIG. 4.

FIG. 4 is a perspective view illustrating an intake/exhaust duct according to an exemplary embodiment of the present invention. As shown in FIG. 4, the intake/exhaust duct 101 includes an intake duct 102 and an exhaust duct 103. The intake duct 102 includes a first unit 102a and a second unit 102b and the exhaust duct 103 also includes a first unit 103a and a second unit 103b. The first unit 102a of the intake duct 102 and the first unit 103a of the exhaust duct 103 are combined to thereby form a combined part. The second unit 102b of the intake duct 102 and the second unit 103b of the exhaust duct 103 are divided from the combined part, thereby forming a divided part. Particularly, each unit of the divided part is bent from the combined part when divided from the combined part.

When the intake/exhaust duct 101 is installed, the combined part is mostly located within a through-hole in a wall and the divided part is located outdoors. For this reason, only a single through-hole perforation is required in the location of the combined part, and accordingly, the number of through-hole perforations required as well as the installation time needed may be reduced, as compared with the case that the intake duct and the exhaust duct are separately installed.

Meanwhile, the combined part may have a cylindrical shape. In this case, since the combined part may have the same shape as that of the through-hole of the wall where the intake/exhaust duct is installed, the size of the through-hole may be reduced and the space between the through-hole and the combined part may also be reduced.

Also, as shown in FIG. 4, the combined part may be formed by combining the first unit 102a of the intake duct 102 and the first unit 103a of the exhaust duct 103 to have a cross-sectional yin-yang shape. In the case of having a cross-sectional yin-yang shape, air flow resistance (fluid resistance) in the unit of the same dimension may be minimized, and accordingly, the amount of air flow may be increased. However, the invention is not limited thereto. The first unit 102a of the intake duct 102 and the first unit 103a of the exhaust duct 103 may be combined while having a variety of cross-sectional shapes.

The divided part may be formed in such a manner that the second unit 102b of the intake duct 102 and the second unit 103b of the exhaust duct 103 may be directed in different directions. If the intake duct 102 and the exhaust duct 103 are disposed outdoors to be directed in different directions, the air drawn into the intake duct 102 and the air discharged from the exhaust duct 103 may be separately divided and prevented from being commingled. FIG. 4 illustrates that the second unit 102b of the intake duct 102 and the second unit 103b of the exhaust duct 103 are directed in opposing directions, but the invention is not limited thereto. If they are directed in different directions, it is considered to be within the scope of the invention.

Meanwhile, the intake duct 102 and the exhaust duct 103 may be formed of polyvinyl chloride (PVC). PVC has good malleability properties, so it may facilitate the manufacturing of the intake/exhaust duct 101 with greater ease. However, the invention is not limited thereto. The intake duct 102 and the exhaust duct 103 may be formed of a metal such as copper that provides good durability.

Also, the intake duct 102 and the exhaust duct 103 may be separately manufactured and subsequently bonded with an adhesive to form the combined part. Alternatively, the intake/exhaust duct may be integratedly manufactured.

Referring to FIG. 5, the ventilating apparatus 100′ for total heat exchange according to this embodiment may further include an adapter part 105. FIG. 5 (a) schematically illustrates the adapter part 105 combined with the intake/exhaust duct 101, and FIG. 5 (b) schematically illustrates the inner structure of the adapter part 105. As shown in FIGS. 5 (a) and 5 (b), the adapter part 105 may include an intake part 106 connected to the end of the first unit 102a of the intake duct 102 and allowing air to be drawn from the intake duct 102, and an exhaust part 107 connected to the end of the first unit 103a of the exhaust duct 103 and allowing air to be discharged into the exhaust duct 103. The adapter part 105 may allow the intake/exhaust duct 101 to be connected to another apparatus, thereby increasing the possibility of its application.

The intake part 106 may include an element (shown as “A” in FIG. 5B) connected to the first unit 102a of the intake duct 102 in the intake/discharge duct 101, whereby the intake part 106 together with the first unit 102a of the intake duct 102 forms a path through which outdoor air is drawn into the heat exchange ventilating apparatus disposed indoors. Likewise, the exhaust part 107 may include an element (shown as “B” in FIG. 5B) connected to the first unit 103a of the exhaust duct 103 in the intake/discharge duct 101, whereby the exhaust part 107 together with the first unit 103a of the exhaust duct 103 forms a path through which the indrawn air is discharged outdoors from the heat exchange ventilating apparatus.

FIGS. 5A and 5B schematically illustrate the heat exchange ventilating apparatus including the adapter part according to an exemplary embodiment of the present invention. However, the invention is not limited thereto. Rather, the ventilating apparatus may be connected to each of a separate intake duct and a separate exhaust duct, and thus air may be separately drawn in or discharged.

Meanwhile, although not shown in FIG. 3, the ventilating apparatus 100′ for total heat exchange may further include a cover part which covers the divided part of the intake/exhaust duct 101. The cover part covers the divided part of the intake/exhaust duct 101 that may be exposed outdoors when the ventilating apparatus 100′ for total heat exchange is installed, thereby making the unit presentable and protecting the intake/exhaust duct 101.

FIG. 6 is a perspective view schematically illustrating a cover part according to an exemplary embodiment of the present invention. As shown in FIG. 6, a cover part 104 covers the divided part formed of the second unit 102b of the intake duct 102 and the second unit 103b of the exhaust duct 103. In the cover part 104, the parts corresponding to the second unit 102b of the intake duct 102 and the second unit 103b of the exhaust duct 103 may have nets or grills allowing for the intake and discharge of air. Since the divided part disposed outdoors is covered by the cover part 104, a presentable appearance may be realized and foreign objects included in the outdoor air may be prevented from being drawn in through the intake duct 102.

In the enlarged view of FIG. 6, only one part of the cover part 104, corresponding to the second unit 102b of the intake duct 102, is illustrated to have a net or grill. However, the other part of the cover part 104, corresponding to the second unit 103b of the exhaust duct 103 in an opposing direction, also has a shutter.

As set forth above, a heat exchange ventilating apparatus according to exemplary embodiments of the invention allows for the enhancement of intake/discharge efficiency by varying its inner structure.

Also, when installed, a heat exchange ventilating apparatus according to exemplary embodiments of the invention reduces the number of holes to be perforated.

While the present invention has been shown and described in connection with the exemplary embodiments, it will be apparent to those skilled in the art that modifications and variations can be made without departing from the spirit and scope of the invention as defined by the appended claims.
