Description

  The present invention relates to a heat exchange type ventilator.

  In recent years, with the global warming, the energy saving in the residential field has become important. Since energy consumption of hot water supply, lighting, air conditioning, and ventilation is relatively large among energy consumption in a house, a technology for reducing these energy consumptions is highly desired.

  Focusing on the air conditioning load of the house, there is heat lost from the housing of the house (cooling in the case of cooling) and heat lost by ventilation. The heat lost from the housing of housing has been considerably reduced by the significant improvement in heat insulation and airtightness of the housing in recent decades. In addition, high insulation and high airtightness of window glass and window glass sashes, which have been delayed compared to the improvement of heat insulation and airtightness of wall surfaces, are gradually progressing. However, with the increase in the airtightness of houses, there may be a difference in the heat insulation performance between the wall surface and the window glass, and there has also been a problem that condensation is concentrated on the surface where heat insulation is insufficient. On the other hand, in order to reduce the heat escaped by ventilation, a heat exchange type ventilator that exchanges heat between the exhaust flow and the supply airflow is effective.

  The heat exchange type ventilator has a high heat recovery effect and can reduce air conditioning energy, particularly in a cold region where the temperature difference between the room and the room is large or in winter. However, the conventional heat exchange type ventilator is arranged on the back of the ceiling or the like, and it is necessary to run a duct in order to distribute air to each living room, so there is a problem that a large-scale construction is required.

  In order to easily construct a heat exchange ventilator for these problems, studies have been made to attach a heat exchange ventilator to a window glass and ventilate heat without using a duct. (For example, refer to Patent Document 1).

  In order to realize these, this type of heat exchange type ventilator has the following configuration.

  As shown in FIG. 9, the unit 101 includes an electric shutter box 102 and a curtain box 103. The unit 101 is provided with an indoor opening 104 on the side surface of the unit 101 facing the indoor space, and faces the outdoor space. An outdoor opening 105 is provided on the side surface of 101. A space above the window glass sash portion 106 is provided with a supply / exhaust fan 107 that blows the supply / exhaust flow, and the supply / exhaust flow is provided via a heat exchanger 108 provided adjacent to the supply / exhaust fan 107. Heat exchange.

Japanese Patent Laid-Open No. 11-230570

  Such a conventional heat exchange type ventilator needs to be equipped with both an electric shutter and a curtain, and there is a problem that versatility is insufficient. In addition, as described above, the insulation of the window glass is often insufficient in the insulation of the wall surface, and there is little action to suppress condensation on the window glass surface that occurs in winter, etc., harming the comfort in the room and further eliminating condensation However, there was a problem of increasing the air conditioning load.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object of the present invention is to provide a heat exchange type ventilator that can be miniaturized and suppresses condensation on the window glass surface.

  In order to achieve this object, the present invention provides a lighting section, a window glass frame formed so as to surround an outer periphery of the lighting section, and the window glass frame provided on an exhaust surface provided on a surface facing the room. An exhaust air passage that communicates an inlet and an exhaust outlet provided on a surface facing the outside, a supply air outlet provided on a surface facing the room, and a supply air inlet provided on a surface facing the outside An air supply air passage that communicates, an air supply blower in the air supply air passage, an exhaust air blower in the exhaust air passage, and the air supply air passage and the exhaust air passage are arranged so as to follow the respective air blowing directions. It is divided by the heat-transfer plate made to achieve the intended purpose.

  As described above, according to the present invention, the window glass frame and the window glass frame formed so as to surround the outer periphery of the daylighting unit and the daylighting unit are provided on the surface facing the outside and the exhaust inlet provided on the surface facing the room.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiment described below exemplifies a blower device for embodying the technical idea of the present invention, and the present invention does not specify the blower device as follows. Further, the members shown in the claims are not limited to the members described in the examples. In particular, the dimensions, materials, shapes, relative arrangements, and the like of the constituent members described in the embodiments are not intended to limit the scope of the present invention only to the description unless otherwise specified. It is just an example. Note that the size, positional relationship, and the like of the members shown in each drawing may be exaggerated for clarity of explanation. Furthermore, in the following description, the same name and symbol indicate the same or the same members, and detailed description thereof will be omitted as appropriate. In addition, each element constituting the present invention may be configured such that a plurality of elements are constituted by the same member and the plurality of elements are shared by one member, and conversely, the function of one member is constituted by a plurality of members. It can also be realized by sharing. Note that the contents described in some examples and embodiments may be used in other examples and embodiments.

  In the heat exchange type ventilator according to claim 1 of the present invention, the window glass frame and the window glass frame formed so as to surround the outer periphery of the daylighting unit and the daylighting unit are provided on an exhaust inlet provided on a surface facing the room. And an exhaust air outlet that communicates with an exhaust outlet provided on a surface facing the outside, and a supply air outlet that is provided on a face that faces the room communicates with a supply air inlet that is provided on the face facing the outside. An air supply passage, an air supply fan in the air supply air passage, an exhaust air blower in the exhaust air passage, and the air supply air passage and the exhaust air passage are arranged so as to follow the respective air blowing directions It has the structure divided by. As a result, the window glass frame and the heat exchange ventilator are integrated, and the air supply air flowing through the supply air passage and the exhaust air flowing through the exhaust air passage are heat-exchanged via the heat transfer plate, and the air supply outlet Since the outdoor air that has been heat-exchanged from the air flows out to the surface of the daylighting unit, it is possible to provide a heat exchange type ventilator that enables downsizing as described above and suppresses condensation on the daylighting unit surface. Play.

  The air supply outlet may be provided on the side surface of the window glass frame on the daylighting unit side. Thereby, because the air supply outlet is arranged at a position adjacent to the daylighting unit surface, the outdoor air whose temperature has increased due to heat exchange flows out directly toward the daylighting unit surface, so that the ventilation effect is enhanced. There is an effect of further suppressing condensation on the surface of the daylighting unit.

  Moreover, it is good also as a structure provided along the outer periphery of a lighting part, the ventilation direction of an air supply path and the ventilation direction of an exhaust air path are facing. Thereby, since the heat exchange between the supply air flow and the exhaust flow is promoted by taking a long supply air passage and an exhaust air passage, that is, by taking a long heat transfer plate, there is an effect of suppressing dew condensation on the surface of the lighting section. .

  Further, the air supply path may be formed closer to the daylighting unit than the exhaust air path. As a result, the effect from the pressure loss in the air passage can be reduced by close proximity from the air supply air passage to the air supply air outlet, thus increasing the ventilation effect on the lighting section surface and suppressing condensation on the lighting section surface. The effect of doing.

  Moreover, it is good also as a structure provided with an at least 1 supply air outlet in the lower part rather than the center part of a lighting part among the outer peripheral parts of a lighting part. Since warm air has the property of rising lighter than cold air, this allows the outdoor air whose temperature has risen due to heat exchange from the lower part of the central part of the daylight to blow out into the room, thereby cooling the daylight cooled by the daylighting part. As the cold air around the head is moved to other places, it rises along the surface of the daylighting unit, and evenly passes through the daylighting unit surface until reaching the upper part of the daylighting unit. Play.

  In addition, the air supply outlet having two or more different types of opening areas, and the opening area of the air supply outlet close to the air supply inlet along the supply air path in the plurality of air supply outlets is the supply air path. It is good also as a structure smaller than the opening area of the air supply outlet which left | separated from the air supply inlet along. Thereby, it becomes a structure where the ventilation resistance of the air supply outlet arrange | positioned upstream of an air supply air path is high compared with the air supply outlet provided downstream. Ventilation resistance from the air supply inlet to each air supply outlet is made uniform by changing the airflow resistance at the air supply outlet, and the outdoor air is uniformly ventilated from all the air supply outlets toward the daylighting unit surface. As a result, the ventilation effect on the surface of the daylighting portion is enhanced, and the effect of suppressing condensation on the surface of the daylighting portion is achieved.

  Moreover, it is good also as a structure provided with the opening / closing apparatus which equips the vicinity of a supply airflow inlet with the at least 1 supply airflow outlet among several supply airflow outlets, and can open and close the supply airflow outlet provided in the vicinity of a supply airflow inlet. As a result, when the temperature and humidity difference between the indoor space and the outdoor space is small, the air supply air path is shortened by opening the opening and closing device, and ventilation can be performed with less energy consumption. Furthermore, when the temperature / humidity difference is large, the air supply air passage can be made longer by closing the switchgear, and heat exchange by the heat transfer plate is promoted, so heat exchange air operation can be performed more efficiently. There is an effect.

  Further, the supply air direction adjustment plate provided at the supply air inlet and the exhaust air direction adjustment plate provided at the exhaust outlet may be inclined in directions opposite to each other. This avoids mixing outdoor air that flows in from the air supply inlet and indoor air that flows out from the exhaust outlet, and improves ventilation efficiency, so that the heat exchange air operation can be performed more efficiently. Play.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, the window glass provided with the heat exchange type ventilation apparatus 2 is installed in the wall surface 1 of the house.

  Indoor air (hereinafter referred to as indoor air) is discharged to the outside through the heat exchange type ventilator 2, and outdoor air (hereinafter referred to as outdoor air) is taken into the room via the heat exchange type ventilator 2. It is done.

  FIG. 2 is a perspective view of the heat exchange ventilator 2 of the present embodiment as viewed from the indoor space.

  FIG. 3 is a perspective view of the heat exchange ventilator 2 of the present embodiment as viewed from the outdoor space.

  FIG. 4 is a cross-sectional view showing a cross section of the heat exchange ventilator 2 of the present embodiment cut in parallel to the surface of the window glass 4.

  In this embodiment, as shown in FIGS. 2 and 3, the heat exchange ventilator 2 is provided with the heat exchange ventilator 2 in the window glass frame 3, and is a lighting unit in the center of the window glass frame 3. Window glass 4 is provided. The window glass frame 3 is made of a hollow member so that indoor air and outdoor air circulate inside the window glass frame 3. A surface of the window glass frame 3 facing the indoor space is provided with an air supply outlet 6 for supplying outdoor air into the room and an exhaust inlet 5 for sucking the indoor air. The air supply inlet 7 for sucking the outdoor air and the exhaust outlet 8 for discharging the indoor air are provided on the surface opposite to the interior, and the indoor air is blown outside the window glass frame 3. An exhaust blower 9 and an air supply blower 10 for blowing outdoor air into the room are provided. The air supply inlet 7, the air supply blower 10, and the air supply outlet 6 communicate with each other in the internal space of the window glass frame 3 to form an air supply air passage 11. Further, the exhaust inlet 5, the exhaust blower 9, and the exhaust outlet 8 are also communicated with each other in the internal space of the window glass frame 3 to form an exhaust air passage 12. The supply air passage 11 and the exhaust air passage 12 are arranged as independent spaces inside the window glass frame 3, and outdoor air drives the supply air blower 10, so that the supply air flow passage 11 is connected to the supply air flow passage 11. The indoor air is circulated from the exhaust inlet 5 to the exhaust outlet 8 via the exhaust air passage 12 by driving the exhaust blower 9. The supply air passage 11 and the exhaust air passage 12 are adjacent to each other, and the contacting surfaces are separated by an aluminum plate 13 that is a heat transfer plate. With this configuration, the window glass frame 3 and the heat exchange type ventilator 2 are integrated, and the heat of the supply airflow that flows through the supply air passage 11 and the heat of the exhaust flow that passes through the exhaust air passage 12 pass through the aluminum plate 13. The outdoor air that has been heat-exchanged and heat-exchanged from the air supply outlet 6 flows out to the indoor surface of the window glass 4. In particular, in winter, indoor air having a high temperature and outdoor air having a low temperature are heat-exchanged, and the warmed outdoor air flows out to the surface of the window glass 4. Thereby, it is a heat exchange type ventilation apparatus excellent in miniaturization, Comprising: The dew condensation on the window glass 4 surface can be suppressed.

  The air supply outlet 6 may be provided on the side surface of the window glass frame 3 on the window glass 4 side.

  With this configuration, the supply air outlet 6 is disposed at a position adjacent to the window glass 4, so that the temperature is increased due to heat exchange compared to the cooled indoor air near the surface of the window glass 4. Since outdoor air flows out directly toward the window glass 4 surface and enhances the ventilation effect, dew condensation on the window glass 4 surface can be suppressed.

  Further, the air blowing direction of the supply air passage 11 and the air blowing direction of the exhaust air passage 12 are opposed to each other, and are provided along the outer periphery of the window glass 4.

  With this configuration, the air supply air passage 11 and the exhaust air passage 12 are made longer, that is, the aluminum plate 13 is taken longer as the air supply air passage 11 and the exhaust air passage 12 become longer, so that the area for heat exchange increases. By promoting the heat exchange between the air supply airflow and the exhaust airflow, the air coming out of the air supply airflow outlet 6 becomes warm, and condensation on the surface of the window glass 4 can be suppressed.

  The supply air passage 11 may be formed on the window glass 4 side with respect to the exhaust air passage 12.

  With this configuration, since the air path distance from the air supply air path 11 to the air supply air outlet 6 is reduced, the pressure loss of the air supply air flowing through the air supply air path 11 can be reduced. The effect is enhanced and condensation on the surface of the window glass 4 can be suppressed.

  Moreover, it is good also as a structure provided with the air supply outlet 6 of at least one location below the window glass 4 center part among the outer peripheral parts of the window glass 4. FIG.

  With this configuration, compared with the cooled indoor air in the vicinity of the surface of the window glass 4, the outdoor air that has a low air density due to the heat exchange and the temperature rises and is likely to rise in the upper part of the indoor space is supplied with air. Since it supplies from the lower part of the window glass 4 from the exit 6, since it ventilates to the surface uniformly until it reaches the upper part of the window glass 4, the dew condensation on the window glass 4 surface can be suppressed.

  FIG. 5 is a cross-sectional view showing a cross section of a heat exchange type ventilator 2 of another example of the present embodiment cut in parallel to the surface of the window glass 4.

  As shown in FIG. 5, a plurality of air supply outlets 6 are provided from the upstream side to the downstream side of the air supply air passage 11 except for the upper portion of the window glass 4 in the outer peripheral portion of the window glass 4. It is good also as a structure provided with the shutter 14 which is an opening / closing device which can open and close the air supply outlet 6 arrange | positioned in the position nearest to the air supply fan 10, ie, the upstream part of the air supply air path 11. FIG. Thereby, it is possible to prevent the outdoor air having a low temperature that is hardly subjected to heat exchange from flowing out of the air supply outlet 6 in the season such as winter by closing the shutter 14. On the other hand, in the season such as summer, when it is desired to increase the ventilation amount and to vent the outdoor air, by opening the shutter 14, the ventilation amount from the supply air outlet 6 upstream of the supply air passage 11 is increased. be able to.

  The air supply outlet 6 is an air supply outlet 6 having two or more different types of opening areas, and the air supply outlet 6 is close to the air supply inlet 7 along the air supply path 11 among the plurality of air supply outlets 6. The opening area of 6 may be configured to be smaller than the opening area of the air supply outlet 6 separated from the air supply inlet 7 along the supply air passage 11. In this case, the airflow resistance of the air supply outlet 6 disposed upstream of the air supply passage 11 is higher than that of the air supply outlet 6 disposed downstream. By changing the ventilation resistance of the air supply outlet 6 in this way, the ventilation resistance from the air supply inlet 7 to each of the air supply outlets 6 is made uniform, and the outdoor air is uniformly distributed from all the air supply outlets 6 to the windows. Since it can ventilate toward the surface of the glass 4, the ventilation effect to the surface of the window glass 4 can increase, and dew condensation can be suppressed.

  FIG. 6 is a plan view showing the air supply inlet 7 and the exhaust outlet 8 of the heat exchange type ventilator of the present embodiment.

  As shown in FIG. 6, a direction in which an air supply louver 17 that is an air supply air direction adjusting plate provided at the air supply air inlet 7 and an exhaust louver 18 that is an exhaust air direction adjusting plate provided in the exhaust air outlet 8 are opposed to each other. It is good also as a structure which has an inclination. This prevents a so-called short circuit in which the outdoor air flowing in from the air supply inlet 7 and the indoor air flowing out from the exhaust outlet 8 are mixed, and improves the ventilation efficiency, so that the heat exchange air operation can be performed more efficiently. It can be carried out.

  An outdoor air supply filter 19 may be provided at the air supply air inlet 7 and an outdoor exhaust filter 20 may be provided at the exhaust air outlet 8. This prevents substances other than air from entering the supply air passage 11 and the exhaust air passage 12 by preventing substances other than air (sand, dust, etc.) from flowing into the supply air passage 11 and the exhaust air passage 12. Prevent inflow. A filter that prevents the passage of chemical substances may be used.

  FIG. 7 is a plan view showing the exhaust inlet 5 of the heat exchange type ventilator of the present embodiment.

  In addition, as shown in FIG. 7, it is good also as a structure which provided the indoor exhaust filter 21 in the exhaust inflow port 5. As shown in FIG. As a result, solid matter such as dust in the indoor space is prevented from flowing into the exhaust air passage 12, so that the solid matter is clogged in the exhaust air passage 12, and the solid matter becomes ventilation resistance. Decrease can be prevented.

  FIG. 8 is a cross-sectional view showing an example of an air supply blower 10 and an exhaust blower 9 of the heat exchange type ventilator of the present embodiment.

  In addition, as shown in FIG. 8, it is good also as a structure which makes the aluminum plate 22 the surface which the supply air blower 10 and the exhaust air blower 9 contact | connect. The supply air flow blown by the supply air blower 10 and the exhaust flow blown by the exhaust blower 9 disturb the wind inside each blower, so that heat transfer is promoted to improve the heat transfer rate. Thereby, the heat exchange between the outdoor air blown from the air supply blower 10 and the indoor air blown from the exhaust blower 9 is promoted, and the outdoor air heat-exchanged from the air supply outlet 6 to the surface of the window glass 4 flows out. Therefore, dew condensation on the window glass 4 surface can be suppressed.

  In addition, as shown in FIG. 5, it is good also as a structure provided with the wind direction board 15 in the air path where the exhaust air path 12 inside the window glass frame 3 bends. Thereby, the exhaust flow flowing through the exhaust air passage 12 circulates along the wind direction plate, pressure loss in the exhaust air passage 12 can be reduced, the exhaust flow becomes easy to flow, and heat exchange between the supply air flow and the exhaust flow can be performed. Promoted. Since outdoor air heat-exchanged from the air supply outlet 6 to the surface of the window glass 4 flows out, condensation on the surface of the window glass 4 can be suppressed.

  In addition, it is good also as a structure which makes the curve part of the aluminum plate 13 and the supply air path 11 into a smooth curve. Thereby, the supply airflow flowing through the supply air passage 11 and the exhaust flow flowing through the exhaust air passage 12 circulate along a smooth curve, and pressure loss in the supply air passage 11 and the exhaust air passage 12 can be reduced. Therefore, a heat exchange type ventilator with lower energy consumption can be provided.

  The indoor air supply filter 16 may be provided at the air supply outlet 6.

  The surface of the window glass frame 3 facing the indoor space may be painted black. With this configuration, since the window glass frame 3 absorbs the temperature of the indoor space by radiant heat, heat exchange between the air supply air flow and the indoor space is promoted, and the outdoor air heat-exchanged from the air supply air outlet 6 flows out efficiently. Heat exchange air operation and dew condensation on the surface of the window glass 4 can be suppressed.

  In addition, it is good also as a structure which provides a heat insulating material, for example, a foaming polyurethane sheet etc., in the side surface of the window glass frame 3 in the surface facing outdoor space. With this configuration, since the temperature of the outdoor space is prevented from being transmitted to the window glass frame 3, the temperature loss of the exhaust flow is suppressed, and the heat exchange efficiency is improved. Surface condensation can be suppressed. Further, as the material of the window glass frame 3, a resin having excellent heat insulation, heat insulation, and airtightness, for example, polystyrene containing closed-cell foam may be used. It is.

  In the specification, the aluminum plates 13 and 22 are described. However, in order to perform heat exchange, sensible heat exchange using a material that transmits only heat, for example, a metal such as aluminum or iron, or a resin such as polypropylene or polystyrene. Alternatively, it may be a total heat exchange using a material that transmits both heat and humidity, for example, a resin such as paper or polyurethane. Furthermore, if a material that transmits only heat is used, when the outdoor temperature is lower than that of the room, the supply air supplied to the room is warmed by the heat of the exhaust and the relative humidity decreases. It becomes easy to evaporate and the effect of suppressing dew condensation on the window glass surface is enhanced, which is more preferable. For such a metal, aluminum may be a light and inexpensive material, and for a resin, a material having a high thermal conductivity as a filler is more preferable.

  The heat exchange ventilator and the window glass according to the present invention are useful as a heat exchange ventilator that enables heat exchange between the room and the outdoors. It is effective when used mainly for building window glass.
