Description

  The present invention relates to a radiation type air conditioner.

  The air conditioner may feel uncomfortable when a blow of cold air or hot air directly hits a person. In addition, when the air conditioner is automatically turned on and off by the thermo switch, the room temperature may go up and down accordingly, which may cause discomfort. Furthermore, turning the air conditioner switch on and off also consumes unnecessary power.

  On the other hand, there is an air conditioner that cools or heats a radiation panel using cold water or hot water as a heat medium. In this case, the cooled panel absorbs far infrared rays, or the heated panel emits far infrared rays, thereby cooling and heating. However, there is a problem that this requires a water transfer facility for introducing cold water or hot water as a heat medium. Further, in order for a person in the room to feel comfortable, it is necessary to touch not only radiant heat such as far-infrared rays but also some cold and warm air, but this radiant air conditioner also has a problem that this point is lacking.

  In view of this, a radiant air conditioner that cools or heats a radiant panel using cold air adjusted by an air conditioner as a heat medium has been proposed. For example, a radiant panel unit and a radiant air conditioner described in Patent Document 1 suspend a radiant panel from a ceiling and use a space between the radiant panel and the ceiling as an air blowing path as a heat medium. Alternatively, a vertical radiant panel may be attached with a certain distance from the wall, and a space between the radiant panel and the wall may be used as an air blowing path as a heat medium.

  The radiant panel is provided with a large number of slit holes, and the cool / warm air blown from the air conditioner is discharged into the room through the large number of slit holes provided in the panel while cooling or heating the radiant panel. The air released into the room is taken into the air conditioner again. Such an air conditioner does not require a pipe for introducing cold water or hot water, and the installation man-hour at the site is reduced. Further, this device has a function that allows cold and warm air to touch the skin.

  Patent Document 2 describes a radiant air conditioner that has a configuration in which a radiant panel and an air passage are integrated to form a duct with a radiant panel. In the long duct structure, the apparatus has a structure in which three surfaces are heat insulating walls and the other surface is a radiation panel made of an aluminum plate. Further, in this apparatus, a vertical aluminum heat transfer member is provided on the side of the radiating channel of the radiation panel. This is a structure that is provided for the purpose of efficiently exchanging heat with the radiant panel, instead of cold air simply passing through the air passage. This duct structure with a radiation panel is also installed on the ceiling or on a vertical wall.

  Incidentally, Patent Document 1 has the following problems. That is, it requires a man-hour in the field where a frame is passed to a ceiling or a wall in a lattice shape, a fixture is attached, and a radiation panel is suspended from the frame. Therefore, there is a demand for further reducing the number of man-hours on site. In addition, since the radiation type air conditioner has many slit holes in the radiation panel, when it is installed vertically on the wall, cooling air is released from the many slit holes located at the feet. There is a problem that the person in the room feels uncomfortable. On the other hand, the radiation type air conditioner described in Patent Document 2 has a problem that it cannot obtain the comfort that some cold / warm air touches the skin because cold / warm air is not released indoors.

  Therefore, the object of the present invention, that is, the technical problem to be solved, is that the cool air can be discharged indoors while the air flow path of the cool air that is the heat medium is constituted by the duct, and the cold air is generated at the foot during cooling. An object of the present invention is to provide a radiant air conditioner that prevents the emission.

[First Embodiment]
<Structure of air passage>
Based on FIG. 1, 1st Embodiment which concerns on the radiation type air conditioner of this invention is described. FIG. 1A is a perspective view of the radiation type air conditioner A, and FIG. The radiant air conditioner A has a flat and substantially hexahedral shape. The radiant air conditioner A is installed on a wall surface of a room to be air-conditioned. An air passage 3 is formed inside the radiant air conditioner A. The air passage 3 is divided into two right and left discharge air passages 32L and 32R and a heat exchange air passage 31 sandwiched between them by a pair of right and left discharge air passage walls 62 extending in the vertical direction. Further, the heat exchange air passage 31 is divided into an upper heat exchange air passage 311 and a lower heat exchange air passage 312 by a wind speed increasing plate 6 which will be described later.

  In the vicinity of the center of the heat exchange air passage 31 in the vertical direction, there is provided a wind speed increasing plate 6 that partitions the heat exchange air passage 31 into an upper heat exchange air passage 311 and a lower heat exchange air passage 312. As shown in FIG. 1B, the wind speed enhancing plate 6 is provided with wind speed enhancing holes 61a, 61b, 61c and 61d, and the upper heat exchange air passage 311 and the lower heat exchange air passage 312 are communicated with each other. Yes.

  In the radiant air conditioner A, air cooled or heated by an air conditioner 7 (not shown) is first introduced into the upper heat exchange air passage 311 through the heat medium air introduction pipe 15. The introduced heat medium air exchanges heat with the radiation panel 21 described later. That is, when the heat medium air is cooled, the heat medium air cools the radiant panel 21 and the heat medium air itself is heated accordingly. When the heat medium air is heated, the heat medium air heats the radiation panel 21 and the heat medium air itself is cooled by that amount. Thereafter, the heat medium air moves through the wind speed increasing holes 61a, 61b, 61c, 61d to the lower heat exchange air passage 312 and performs heat exchange with the radiation panel 21 again.

  Discharge communication ports 33L and 33R through which heat medium air passes are respectively provided between the heat exchange air passage 31 and the discharge air passage wall 62 that partitions the discharge air passages 32L and 32R. The heat medium air that has reached the discharge air passage 32L or the discharge air passage 32R through the discharge communication ports 33L and 33R is discharged into the room from the discharge holes 121a or 121b described later. The indoor air is taken into the air conditioner 7 (not shown) and cooled or heated again.

  As shown in FIG. 1B, when the heat medium air introduction pipe 15 is introduced into the upper heat exchange air passage 311, the discharge communication ports 33L and 33R are arranged on the lower heat exchange air passage 312 side, particularly Provided below. 1B, when the heat medium air introduction pipe 15 is introduced into the lower heat exchange air passage 312, the discharge communication ports 33L and 33R are connected to the upper heat exchange air passage 311 side. In particular, it is provided above. With such a configuration, it is possible to prevent the heat medium air introduced from the heat medium air introduction pipe 15 from being directly discharged into the room without circulating around the air passage 3.

  The air passage 3 of the radiant air conditioner A includes an upper wall surface 11, a bottom wall surface 13, a pair of left and right side wall surfaces 12, 12, a wall surface orthogonal to the side wall surface 12, a rear wall surface 14, and a room interior. Is formed as a flat and substantially hexahedron. Among these wall surfaces, the upper wall surface 11, the bottom wall surface 13, the side wall surface 12, and the back wall surface 14 are formed of a heat insulating member. These may be formed of, for example, a vinyl chloride resin, or may be formed by spraying a heat insulating member on the surface after being molded with a metal plate.

  That is, up to five of the six surfaces of the radiation type air conditioner A have heat insulation properties. And the radiation type air conditioner A is installed so that the back wall surface 14 may follow an indoor wall. In the example of FIG. 1, the heat medium air introduction pipe 15 that introduces air that is cooled or heated from an air conditioner (not shown) is bent upward by 90 degrees and then provided on the upper wall surface 11.

<Discharge hole>
The left and right side wall surfaces 12 are provided with discharge holes 121 on at least one of both side surfaces. As the discharge holes 121, there are an upper discharge hole 121a and a lower discharge hole 121b. The upper discharge hole 121a is provided above the side wall surface 12, and discharges the heat medium air in the air blowing path 3 upward in the room. On the other hand, the lower discharge hole 121b is provided below the side wall surface 12, and discharges the heat medium air in the blower passage 3 to the indoor lower side. In either case, the heat medium air introduced into the air passage 3 through the heat medium air introduction pipe 15 circulates through the upper heat exchange air passage 311 and the lower heat exchange air passage 312 and then is released into the room.

  Next, a cross-sectional structure of the radiation type air conditioner A will be described with reference to FIG. FIG. 2A is a cross-sectional view taken along the line X1-X1 of the radiation type air conditioner shown in FIG. The front wall surface 2 has a two-layer structure including a diatomaceous earth cloth 23 and a radiation panel 21 from the side facing the room. The side wall surfaces 12, 12 and the back wall surface 14 are formed of a heat insulating member such as vinyl chloride. The upper wall surface 11 and the bottom wall surface 13 are also formed of a heat insulating member such as vinyl chloride. The radiation panel 21 is formed of, for example, a metal plate such as aluminum. Further, the side wall surfaces 12, 12, the back wall surface 14, the upper wall surface 11 and the bottom wall surface 13 may be formed of a metal such as aluminum and then a heat insulating member may be applied to the surface.

  The heat medium air introduced into the air passage 3 from the heat medium air introduction pipe 15 circulates in the upper heat exchange air passage 311 and the lower heat exchange air passage 312 to cool or heat the radiation panel 21, that is, the radiation panel. Heat exchange with 21. Thereafter, the heat medium air is discharged into the room from the upper discharge hole 121a or the lower discharge hole 121b facing the discharge air passages 32L and 32R.

  As described above, the heat exchange air passage 31 and the discharge air passages 32 </ b> L and 32 </ b> R are partitioned by the discharge air passage wall 62. Since the upper discharge hole 121a and the lower discharge hole 121b are provided on both sides of the radiation panel 21, there is an effect that air discharged from here into the room does not directly hit the person. In order to obtain such an effect, as long as the discharge holes are in the side wall surface 12, it is not always necessary to provide the upper discharge holes 121 a and the lower discharge holes 121 b separately.

<Discharge blocking lid>
The upper discharge hole 121a and the lower discharge hole 121b are provided with a discharge blocking lid 5 that alternately opens and closes them. As shown in FIGS. 2C and 2D, a handle 51 is provided on an elongate lid 52 along the side wall surface 12. The handle 51 is an operation unit operated by the user, and the user can slide the handle 51 up and down along the slide groove 122. For example, if the cover 52 is slid upward, the lid 52 moves upward. And the upper part of the cover body 52 closes by covering the upper discharge hole 121a. At the same time, the lower part of the lid 52 is released from the lower discharge hole 121b.

  On the other hand, if the cover 52 is slid downward, the lid 52 moves downward to open the upper discharge hole 121a and close the lower discharge hole 121b. In order to stop the lid body 52 at a predetermined position, for example, a screw structure can be provided at a connecting portion between the handle 51 and the lid body 52. In this way, when the handle 51 is rotated to the right by a predetermined angle, the lid 52 is clamped and fixed at that position, and when the handle 51 is rotated to the left by a predetermined angle, the lid 52 is released from being clamped. it can.

<Wind speed enhancement plate>
For example, circular wind speed enhancing holes 61a, 61b, 61c, and 61d are provided in the wind speed increasing plate 6 that partitions the air blowing path 3 into an upper heat exchange air path 311 and a lower heat exchange air path 312. The wind speed enhancing holes 61a, 61b, 61c, 61d connect the upper heat exchange air passage 311 and the lower heat exchange air passage 312 as air passages, and increase the air blowing speed of the heat medium air by narrowing the air passages. By this action, the radiation panel 21 is efficiently cooled or heated. The wind speed enhancing plate 6 may be a member with good thermal conductivity such as aluminum or a member with good heat insulation such as vinyl chloride.

<Installation on the wall>
Next, based on FIG. 2 (B), the installation example to the indoor wall of the radiation type air conditioner A is demonstrated. First, the two fixtures 41 are fixed to the indoor wall W with anchor bolts 43 with appropriate widths. Next, the radiation type air conditioner A is installed on the fixed fixture 41 with duct bolts 42. For example, a large bolt hole 123 is formed in the side wall surface 12 so that the duct bolt 42 can be easily passed therethrough. The side wall surface 12 and the fixture 41 are tightened by the duct bolt 42 through the large hole.

  Furthermore, the indoor surface of the radiation panel 21 is covered with a diatomaceous earth cloth 23. Diatomaceous earth cloth is a member that absorbs moisture. With this configuration, even if dew condensation occurs on the indoor surface of the radiation panel 21, the diatomaceous earth cloth absorbs moisture, so that the dew condensation water does not bleed into the room. Diatomaceous earth cloth is wallpaper using diatomaceous earth.

<Air conditioning>
Here, the cooling function of the radiation type air conditioner A will be described with reference to FIG. When the room is cooled, the handle 51 is slid downward, the upper discharge hole 121a is opened in advance, and the lower discharge hole 121b is closed. Then, the air cooled by the air conditioner 7 (not shown) is sent into the heat exchange air passage 31 of the radiant air conditioner A through the heat medium air introduction pipe 15. Then, the cooled air exchanges heat with the aluminum radiation panel 21 while circulating around the upper heat exchange air passage 311 and the lower heat exchange air passage 312. That is, the cooled air is gradually warmed, while the radiant panel 21 is cooled.

  The cooled radiation panel 21 is installed on a wall of an indoor wall and absorbs far-infrared rays emitted by the indoor wall or a person in the room. By this action, far infrared rays coming from the indoor wall can be greatly reduced, and the heat can be avoided. People constantly emit far-infrared rays in all directions, and also in the direction of indoor walls. In such a situation, when the thermal radiation from the far infrared rays is received from the wall side, or the thermal radiation emitted by itself is reflected by the wall and radiated toward itself again, it feels hot. However, if the wall is cooled by the radiation panel 21, it will not receive heat radiation from the wall and will not feel the heat.

  Furthermore, the radiation type air conditioner A according to the present invention is provided with an upper discharge hole 121a and a lower discharge hole 121b on at least one of the pair of left and right side wall surfaces 12, 12. As described above, the lower discharge hole 121b is closed. Then, the heat medium air is discharged into the room from the open upper discharge hole 121a. The air released into the room is cooled by an air conditioner, but is somewhat warmed by heat exchange in the heat exchange air passage 31. This brings about quiet air fluctuations in the room. Since people are constantly radiating heat, they are wearing air heated by their own heat. Since this is removed by the above-mentioned quiet air fluctuation, comfortable cooling can be realized.

  If the radiation type air conditioning unit described in Patent Document 1 is provided on the wall, the radiation type air conditioner also cools the wall, and the cooled air is discharged into the room. However, the device of Patent Document 1 has a large number of emission holes (slits 125) in the radiation panel itself. In this configuration, the cold air from the air conditioner is released as it is below the room, and the cold air may stay near the floor. On the other hand, the radiant air conditioner A of the present invention closes the lower discharge hole 121b, and discharges air having a moderately low degree of cooling in the air passage 3 from the upper discharge hole 121a, so that cold air is near the floor. This has the effect of eliminating the problem of convection.

<Heating function>
Next, based on FIG.2 (D), the heating function of the radiation type air conditioner A which concerns on 1st Embodiment of this invention is demonstrated. When heating the room, the handle 51 is slid upward, the upper discharge hole 121a is closed in advance, and the lower discharge hole 121b is opened. And the air heated with the air conditioner 7 which is not shown in figure is sent in in the heat exchange ventilation path 31 of the radiation type air conditioner A. As shown in FIG. Then, the heated air exchanges heat with the aluminum radiation panel 21 while circulating around the upper heat exchange air passage 311 and the lower heat exchange air passage 312.

  That is, the heated air is gradually cooled, while the radiant panel 21 is heated. Then, warm air is gently discharged into the room through the lower discharge hole 121b. The heated radiation panel 21 emits far-infrared rays and warms a person in the room. In addition, the quiet fluctuation created by the released air realizes comfortable heating.

<Number of discharge holes and opening area>
As described above, the heat medium air is sent from the air conditioner 7 through the heat medium air introduction pipe 15 to the air passage 3 of the radiant air conditioner A. And the amount sent is discharged into the room from the upper discharge hole 121a or the lower discharge hole 121b. At this time, either the upper discharge hole 121a or the lower discharge hole 121b is closed with a lid. Accordingly, each of the upper discharge holes 121a and the lower discharge holes 121b is independent of the number of the discharge holes and the number of openings so as to ensure a sufficient opening for discharging the heat medium air introduced from the heat medium air introduction pipe 15. It is necessary to secure an area.

  In the radiation type air conditioner, it is possible to prevent the air conditioner air from directly hitting a person in the room. Furthermore, there is an effect that the radiant air conditioner A can be constructed simply by introducing air from the air conditioner to the radiant air conditioner installed on the wall through the heat medium air introduction pipe. Furthermore, since the heat medium air discharge holes are provided in the pair of left and right side walls constituting the radiant air conditioner A, cold air can be discharged indoors even though the air passage is formed of a duct. There is an effect.

  Furthermore, it is possible to close the upper discharge hole 121a so that warmed air is discharged from the lower discharge hole 121b. In this way, warm air having a low specific gravity moves upward, and there is an effect that a quiet convection can be generated in the room. Moreover, at the time of air_conditioning | cooling, there exists an effect which can prevent that cold air retains in floor vicinity by plugging the lower discharge | release hole 121b.

[Second Embodiment]
Based on FIG. 3, the radiation type air conditioner according to the second embodiment will be described. The radiation type air conditioner is a radiation type air conditioner using a radiation panel 21B in which two or more recesses, projections, or irregularities are formed on the surface of the radiation panel 21 of the radiation type air conditioner in the first embodiment. (FIG. 3 (A)). Like the radiant panel 21B, by providing so-called embossing on the surface, the surface area is increased, and the radiation efficiency as the radiant panel is improved.

  Alternatively, as shown in FIG. 3 (B1), the central portion of the radiant panel 21C may be slightly expanded downward. This can be seen by comparing with the horizon H. In FIG. 3 (B2), this bulge is exaggerated. With such a configuration, there is an effect that the radiation rays 8 such as far infrared rays are diffused radially and the range on the receiving side is expanded. As described above, the radiation panel 12 </ b> B having unevenness on the surface and the radiation panel 21 </ b> C in which the lower part of the center part slightly swells may be implemented separately or in combination.

[Third Embodiment]
Next, based on FIG. 4, 3rd Embodiment which concerns on the radiation type air conditioner of this invention is described. FIG. 4A is a front view of the radiation type air conditioner, and FIG. 4B is a view taken in the direction of arrows Y1-Y1. The radiation type air conditioner is configured by arranging a plurality of radiation type air conditioners A according to the first embodiment or the second embodiment side by side on a wall surface in a room. However, the upper discharge hole 121a and the lower discharge hole 121b are not opened / closed by the above-described handle 51 and the lid 52 that can be alternately opened / closed, but the upper blocking lid that individually opens / closes each discharge hole. 5a and lower blocking lid 5b. The upper discharge hole 121a is opened and closed by the upper blocking lid 5a, and the lower discharge hole 121b is opened and closed by the lower blocking lid 5b.

  FIG. 4C is a diagram showing a state in which the upper discharge hole 121a is opened and the lower discharge hole 121b is closed by the lower blocking lid 5b. Since the heat medium air is released from the upper part of the room, it is in a state suitable for cooling as described above. FIG. 4D is a view showing a state where the upper discharge hole 121a is closed by the upper blocking lid 5a and the lower discharge hole 121b is opened. Since the heat medium air is released from the lower part of the room, it is in a state suitable for heating as described above.

  Each radiant air conditioner A is supplied with heat medium air, which is cooled or heated by the air conditioner 7, and whose temperature is adjusted, through the heat insulation duct 71 and the heat medium air introduction pipe 15. The sent heat medium air cools or heats the radiation panel 21 of the radiant air conditioner A when circulating through the upper heat exchange air passage 311 and the lower heat exchange air passage 312. Thereafter, the heat medium air is discharged into the room from the upper discharge hole 121a or the lower discharge hole 121b. The heat medium air released into the room has its cold or warm air alleviated when the above-described radiation panel 21 is cooled or heated.

  In this way, air that has been relieved of cold air or warm air is gently released into the room, so that air conditioning that is comfortable for people in the room is realized. Combined with this, far-infrared absorption or radiation by the radiation panel 21 realizes effective cooling and heating.
