Description

The present invention relates to a dehumidifying radiant air conditioning system used for a ceiling, and particularly to a structure of a ceiling panel.

Conventionally, a radiant air conditioning system using heat radiation has been known. When cooling in a radiant air conditioning system, the temperature of the panels around the human is set lower than the human body temperature. This makes the energy lost by radiation higher than the energy absorbed by humans, resulting in the desired cooling effect. At the time of heating, the temperature of the panel around the human is set to a temperature lower than the human body temperature but close to the human body temperature. As a result, the energy absorbed by humans approaches the energy lost by radiation, and the desired heating effect can be obtained. The panel can be installed on the floor, ceiling or wall, but the ceiling has a large area together with the floor, and the effect of air conditioning can be obtained over a wide range and uniformly, so that it is a preferable part for installing the panel. Patent Documents 1 and 2 disclose a dehumidifying radiant air conditioning system in which a dehumidifying function is added in addition to a cooling function. Specifically, by passing cold water through multiple pipelines provided on the ceiling, a cooling effect due to radiation can be obtained, and by generating dew condensation on the surface of the pipeline, moisture in the room is removed. A dehumidifying effect can be obtained. A drain member is installed below the pipeline to prevent the dew condensation water generated on the surface of the pipeline from falling.

Patent Document 3 discloses a dehumidifying radiant air conditioning system installed on a wall. A hydrophilic thin film is formed on the surface of the radiant panel where dew condensation occurs in order to promote the drainage of the dew condensation water.

In the dehumidifying radiant air conditioning system described in Patent Documents 1 and 2, a drain member is installed below the pipeline, but since this drain member shields the pipeline, the desired cooling effect may not be obtained. There is. However, if the drain member is omitted in order to obtain the desired cooling effect, it is not possible to prevent the dew condensation water from falling. Even if a hydrophilic thin film is formed on the surface of the pipeline as in the case of the radiation panel described in Patent Document 3, unlike the dehumidifying radiation air conditioning system installed on the wall, the condensed water can be drained by gravity. Therefore, if the amount of condensed water that can be held by the pipeline is exceeded, the condensed water will eventually fall.

An object of the present invention is to provide a dehumidifying radiant air conditioning system that is installed on the ceiling, has a good dehumidifying and cooling effect, and can drain condensed water.

The dehumidifying radiant air conditioning system of the present invention has at least one panel provided on the ceiling. The panel is provided with a cooling / dehumidifying surface facing the space to be cooled and dehumidified, and the cooling / dehumidifying surface cools the space and dehumidifies the space by generating dew condensation water on the cooling / dehumidifying surface. The cooling dehumidifying surface is inclined with respect to the horizontal direction so as to guide the condensed water to the water while retaining the condensed water. It has a dew condensation water recovery means for recovering the dew condensation water and a drainage pipe connected to the dew condensation water recovery means. The cooling dehumidifying surface has a first portion that guides the dehumidified water to the water while holding it, and a second portion that is provided under the water of the cooling dehumidifying surface and has a lower hydrophilicity than the first portion. ing. The dew condensation water recovery means has a saucer located below the second portion at intervals from the second portion, and the saucer collects the dew condensation water falling from the second portion.

According to the present invention, since the cooling / dehumidifying surface of the panel is inclined with respect to the horizontal direction, the dew condensation water generated on the cooling / dehumidifying surface is guided under the water on the cooling / dehumidifying surface, and the dew condensation formed under the water. It is recovered by water recovery means. Since it is not necessary to provide the dew condensation water recovery means below the cooling dehumidifying surface except under the water of the cooling dehumidifying surface, no other structure intervenes between the cooling dehumidifying surface and the person in the space below. Therefore, according to the present invention, it is possible to provide a dehumidifying radiant air conditioning system that is installed on the ceiling, has a good dehumidifying and cooling effect, and can drain condensed water.

In the following description and drawings, the first direction x is the horizontal direction connecting the water and the water, the second direction y is the horizontal direction orthogonal to the first direction x, and the third direction z is the first direction x.

(First Embodiment)
FIG. 1A is a front view of the dehumidifying radiant air conditioning system 101 according to the first embodiment of the present invention. The dehumidifying type radiant air conditioning system 101 includes a panel 102 having a cooling / dehumidifying surface 21 facing the lower space R, and a cooling means 3 for cooling the panel 102. The panel 102 of the present embodiment constitutes a ceiling panel provided on the ceiling 11. "Provided on the ceiling 11" means that the panel 102 is provided near the ceiling 11 or in contact with the ceiling 11, and whether the panel 102 is supported by the ceiling 11 or supported by something other than the ceiling 11. It doesn't matter. The lower space R is a dehumidifying / cooling target space below the panel 102, which is defined by the wall 12 and the floor 13 which are a part of the building frame and the panel 102. The panel 102 is provided below the ceiling 11 (floor board) which is a part of the building frame. In the present embodiment, the panel 102 is provided apart from the ceiling 11, but a part of the panel 102 may be in close contact with the ceiling 11. The cooling means 3 is provided on the back surface 22 of the cooling / dehumidifying surface 21 of the panel 102, that is, on the surface facing the ceiling 11. 1 (b) is a plan view of the back surface 22 of the cooling / dehumidifying surface 21 of the panel 102 (viewed from the direction A of FIG. 1 (a)), and FIG. 2 (a) is viewed from the same direction as FIG. 1 (a). A partial detailed view of the panel 102 and the cooling means 3, FIG. 2B is a cross-sectional view taken along the line BB of FIG. 1B. In the present embodiment, the cooling means 3 is a cooling pipe 31 arranged on the back surface 22 of the cooling / dehumidifying surface 21 of the panel 102 and through which the refrigerant flows. The cooling pipe 31 is composed of a single pipe meandering on the back surface 22 of the panel 102. The cooling pipe 31 is supported by the panel 102 by a support portion 32 made of a metal having high thermal conductivity. The support portion 32 has a cross-sectional shape in which the cross section increases toward the cooling / dehumidifying surface 21. Since it is easy to secure the contact area of the back surface 22 of the panel 102 with the support portion 32, the cooling efficiency of the panel 102 is improved, and a wider range of the cooling / dehumidifying surface 21 can be efficiently cooled.

The cooling / dehumidifying surface 21 of the panel 102 cools the lower space R. Heat transfer due to heat radiation (radiant heat) occurs between the human being in the lower space R and the cooling / dehumidifying surface 21. ^{The amount of heat transferred is proportional to (Th 4-} Ts ⁴ ), where Th is the surface body temperature (absolute temperature) of a human being in the lower space R and Ts is the surface temperature (absolute temperature) of the cooling / dehumidifying surface 21. Since Ts is set lower than Th, the amount of radiant heat radiated by humans exceeds the amount of radiant heat received, and a desired cooling effect can be obtained. Further, since the temperature of the refrigerant is set lower than the dew point temperature of the air in the lower space R, the temperature of the cooling / dehumidifying surface 21 of the panel 102 is also lower than the dew point temperature of the air in the lower space R. Therefore, the moisture in the lower space R condenses (condenses) on the cooling / dehumidifying surface 21 and is taken into the dew condensation water. As a result, the lower space R is dehumidified.

The panel 102 is inclined with respect to the horizontal direction so as to guide the condensed water under the water while holding the condensed water. Condensed water flows under the water in a film shape along the inclined surface while being held by the cooling / dehumidifying surface 21 by surface tension. The upstream portion of the cooling pipe 31 is located on the water side of the panel 102, and the downstream portion is located on the water side of the panel 102. Therefore, the temperature of the lower side of the panel 102 is lower than that of the upper side of the water, and more condensed water is generated. As will be described later, since the dew condensation water recovery means 4 is provided on the underwater side of the panel 102, by routing the cooling pipe 31 in this way, the moving distance of the dew condensation water moving along the cooling dehumidifying surface 21 can be determined. Can be reduced. Further, even if the condensed water falls from the cooling / dehumidifying surface 21, the amount of the falling condensed water can be suppressed. Guide members 23 projecting downward may be provided at both side ends of the cooling / dehumidifying surface 21 of the panel 102 in the second direction y. The guide member 23 extends from above water to below water along the first direction x, and forms a corner portion together with the cooling / dehumidifying surface 21. Since the condensed water is held at the corners by surface tension, it is difficult for the condensed water to fall from both end portions of the cooling / dehumidifying surface 21 in the second direction y.

As shown in FIG. 2A, the cooling / dehumidifying surface 21 is located under the water of the first portion 21a and the cooling / dehumidifying surface 21 that guides the dehumidified water to the water while holding the condensed water, and the first portion 21a. It has a second portion 21b that is less hydrophilic (more hydrophobic or more water repellent). Condensed water moves toward the underwater side while being held by the surface tension in the first portion 21a, and falls in the second portion 21b without being held by the surface tension. Hydrophilicity is generally defined by the contact angle θ between the tangent of the contour curve at the intersection of the contour curve of the droplet and the solid surface with the solid surface. The smaller the contact angle θ, the greater the wettability and the higher the hydrophilicity. The larger the contact angle θ, the smaller the wettability and the higher the hydrophobicity. The contact angle θ can be easily adjusted by changing the type of surface coating of the first portion 21a and the second portion 21b. The contact angle θ is preferably about 10 ° or less in the first portion 21a, and preferably about 90 ° or more in the second portion 21b. Further, as the surface roughness increases, the contact angle θ decreases on the hydrophilic surface and the contact angle θ increases on the hydrophobic surface. Therefore, the surface roughness is adjusted to adjust the degree of hydrophilicity and hydrophobicity. It is also possible. In order to promote the fall of the condensed water, a protrusion 21c that protrudes downward may be provided in the second portion 21b. When the protrusion 21c is provided, the water repellent treatment of the second portion 21b can be omitted.

The dehumidifying type radiant air conditioning system 1 has a dew condensation water recovery means 4 for recovering the dew condensation water. The dew condensation water recovery means 4 of the present embodiment is a dew condensation water tray located below the second portion 21b at a distance from the second portion 21b. The condensed water falls from the second portion 21b to the condensed water collecting means 4. As shown in FIG. 1B, since the both side ends of the dew condensation water recovery means 4 in the second direction y are outside the side ends of the cooling dehumidifying surface 21 in the second direction y, the cooling dehumidifying surface 21 Almost all of the condensed water that falls from the water can be recovered. The drainage pipe 5 connected to the condensed water recovery means 4 extends downward along the wall 12 of the lower space R, penetrates the wall 12 and reaches the outside of the lower space R. Although not shown, the drainage pipe 5 may extend inside the wall 12. In the present embodiment, no structure is interposed between the cooling / dehumidifying surface 21 and the lower space R except for the dew condensation water recovery means 4 and the drainage pipe 5. That is, since a structure having a surface temperature higher than that of the cooling / dehumidifying surface 21 such as the drain member disclosed in Patent Documents 1 and 2 does not intervene between the cooling / dehumidifying surface 21 and the lower space R (human being). The decrease in cooling effect is prevented.

FIG. 3 is a diagram similar to FIG. 1 (a) showing the modified example 101'of the first embodiment. The cooling means is a cold air supply facility 33 that introduces cold air into the attic space R1 formed by the back surface 22 of the cooling / dehumidifying surface 21 of the panel 102', the ceiling 11 above the panel 102', and the wall 12. The cold air supply facility 33 has an air conditioner 34 that generates cooling air, and a duct 35 that connects the air conditioner 34 to the attic space R1. The duct 35 introduces cold air into the attic space R1 and sucks the cold air from the attic space R1 and returns it to the air conditioner 34. In this modification, as a result of uniformly cooling the back surface 22 of the cooling / dehumidifying surface 21 of the panel 102'with cold air, the cooling / dehumidifying surface 21 is also uniformly cooled, and the cooling effect on the lower space R is further made uniform. A sealing material 6 may be provided between the panel 102'and the wall 12 so that the cold air does not directly flow into the lower space R. Although the panel 102'of this modification does not include the cooling pipe 31, the cooling pipe 31 shown in FIGS. 1 and 2 may be provided as a backup for the air conditioner 34.

Hereinafter, other embodiments will be described. The configurations and effects not specifically described in the following embodiments are the same as in the first embodiment.

(Second Embodiment)
FIG. 4A is a front view of the dehumidifying radiant air conditioning system 201 according to the second embodiment of the present invention, and FIG. 4B is an enlarged view of part A of FIG. 4A. This embodiment has the same configuration as the first embodiment except for the configuration of the dew condensation water recovery means 4'. The dew condensation water recovery means 4'has a first dew condensation water reservoir 41 provided under the water of the cooling / dehumidifying surface 21 and a second dew condensation water reservoir 41 provided on the back surface 22 of the cooling / dehumidifying surface 21 of the panel 202. 42 and the first dew condensation water sump 41 are connected to the second dew condensation water sump 42, and the dew condensation water held in the first dew condensation water sump 41 is transferred to the second dew condensation water sump 42 by capillary force. It has a plurality of thin tubes 43 to be transferred by, a first vertical plate 44 extending downward from the lowest point of the cooling / dehumidifying surface 21, and a second vertical plate 45 extending upward from the lowest point of the back surface 22. The second dew condensation water reservoir 42 is connected to the drainage pipe 5. The dew condensation water flowing in a film shape on the cooling / dehumidifying surface 21 reaches the first dew condensation water reservoir 41. The first dew condensation water reservoir 41 is a first corner portion 41 composed of a cooling / dehumidifying surface 21 and a first vertical plate 44. Condensed water is held in the first corner portion 41 by the surface tension acting between the cooling dehumidifying surface 21 and the first vertical plate 44. The condensed water is transferred to the second condensed water reservoir 42 through the thin tube 43. The second dew condensation water reservoir 42 is a second corner portion 42 composed of a back surface 22 of the cooling / dehumidifying surface 21 of the panel 202 and a second vertical plate 45. The condensed water held in the second corner portion 42 is discharged by the drainage pipe 5 penetrating the second vertical plate 45 in the same manner as in the first embodiment. Since the first corner portion 41 is required to have dew condensation water retention performance, unlike the first embodiment, the cooling and dehumidifying surface 21 under water and its vicinity are hydrophilic. Similarly, the surface of the first vertical plate 44 facing the cooling / dehumidifying surface 21 is also hydrophilic. Since the present embodiment does not require the dew condensation water recovery means 4, the aesthetic appearance seen from the lower space R is improved, and no sound is generated when the dew condensation water falls on the dew condensation water recovery means 4. ..

(Third Embodiment)
FIG. 5A is a front view of the dehumidifying radiant air conditioning system 301 according to the third embodiment of the present invention, and FIG. 5B is a top view of the dehumidifying radiant air conditioning system 301 as viewed from the direction A of FIG. FIG. 5 (c) is a cross-sectional view taken along the line BB of FIG. 5 (b). This embodiment has the same configuration as the first embodiment except that a plurality of panels 302a, 302b, 302c are arranged in a louver shape. The plurality of panels 302a, 302b, 302c extend parallel to each other in the first direction x and are arranged in the second direction y. Further, the plurality of panels 302a, 302b, 302c form louvers that partially overlap each other when viewed in the third direction z (vertical direction). That is, as shown in FIG. 5C, each panel 2 is inclined with respect to the horizontal plane even when viewed from the first direction x. As a result, the condensed water moves not only in the first direction x but also in the second direction y, and moves in a diagonal direction with respect to the first direction x as shown in FIG. 5 (b) (arrow F). ). Since the condensed water is concentrated on the underwater side in the second direction y, as shown in FIG. 5 (c), the condensed water is concentrated on the underwater side of the panels 302a, 302b, 302c in the second direction y. A guide portion 7 may be provided. Each of the panels 302a, 302b, 302c includes a cooling pipe 31. Although the dew condensation water recovery means 4 is commonly provided on the panels 302a, 302b, 302c, individual dew condensation water recovery means 4 may be provided for each of the panels 302a, 302b, 302c. Since the ceiling surface of the present embodiment has a louver-like appearance, the design is improved.

FIG. 6 shows a dehumidifying radiant air-conditioning system 301 ′ according to a modified example of the third embodiment, and FIGS. 6 (a) to 6 (c) correspond to FIGS. 5 (a) to 5 (c), respectively. .. The present embodiment shows the embodiment shown in FIG. 5, except that a plurality of panels 302a', 302b', and 302c' are separated from each other when viewed in the vertical direction (that is, they do not overlap so as to form a louver). It has the same configuration as the form. Specifically, the inclination angle θ of the panels 302a', 302b', and 302c'with respect to the horizontal plane is larger than that of the embodiment shown in FIG. The inclination angle θ is not particularly limited, but may be θ = 90 °. That is, the panels 302a', 302b', 302c' may be installed vertically. In the present embodiment, since the inclination angle θ can be made large, the dew condensation water can be swiftly flowed downward along the cooling dehumidifying surface 21 by gravity, and the dew condensation water can be recovered more efficiently. Further, since the restriction on the number of panels to be installed is small, the cooling / dehumidifying effect can be enhanced by installing more panels.

The underwater of one panel (eg, 402a) adjacent to each other is below the water of the other panel (eg, 402b). Therefore, the centers of gravity of the panels 402a, 402b, and 402c are at substantially the same height in the third direction z (vertical direction). In this embodiment, as compared with the first embodiment, one panel is divided in the first direction x, and the height difference between the water surface and the water surface of each panel 402a, 402b, 402c can be suppressed. , It is easy to secure the indoor height of the lower space R. In the present embodiment, the three panels 402a, 402b, and 402c are arranged in series along the first direction x, but the number of panels (number of divisions) is not limited to this, and any number of panels can be used. The panels can be arranged along the first direction x.
