Description

[Technical Field]

[0001] The present invention relates to an air conditioning system for a room space. [Background technology]

[0002] Conventionally, there is known technology relating to air conditioning systems that provide a comfortable thermal environment (sleeping environment) for bed users by installing a radiant panel that performs radiant heating and cooling by thermal radiation on a support such as a headboard located at the head side of the bed or on a wall. In Patent Document 1, the lower end of the radiant panel is provided with a sloped section (reverse plate) that gradually slopes downward as it approaches the bed. The radiant heat from the radiant panel exchanges heat with the surrounding air, turning it into cooled air (hereinafter referred to as "cold air"), which then flows along the sloped section due to natural convection in the room. This makes it possible to efficiently provide a cooling sensation to the user using the bed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6573114 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, there has been an increasing demand for private, secluded spaces, and securing such a private space is also desired during sleep. Therefore, it has been considered to create a private space by extending the return board (inclined portion) in conventional technology to cover the head of the bed user. However, simply extending the board makes it easy for bed users who sleep below the board to feel a sense of oppression. On the other hand, if the return board is positioned far above the head of the bed user, it is difficult to improve the quality of the private space. In addition to ensuring a secluded space, it is also necessary to provide a comfortable thermal environment (sleeping environment) for bed users.

[0005] The present invention was made in consideration of the above circumstances, and its objective is to create a comfortable thermal environment within a room space by using air whose temperature has been adjusted by a radiant heating and cooling device, while also ensuring a moderate, enclosed space with a reduced feeling of oppression. [Means for solving the problem]

[0006] The invention described in claim 1 is an air conditioning system for a room space 1, as shown in, for example, FIGS. 13 to 16, A wall portion 4 (5) that constitutes the room space 1; a radiant heating and cooling device 12 that is incorporated into and supported by the wall portion 4 and radiates heat from the wall surface of the wall portion 4; and covering bodies 32, 34, and 37 attached to the wall portion 4 and protruding forward from the wall surface of the wall portion 4, The lower surfaces of the coverings 32, 34, and 37 are characterized by being curved upward in a side cross-sectional view.

[0007] According to the invention recited in claim 1, the radiant heating and cooling device 12 is incorporated into and supported on the wall 4 to which the coverings 32, 34, and 37 are attached, so that objects located nearby can be heated or cooled by direct radiant heat from the radiant heating and cooling device 12. In addition, air (cold air) temperature-adjusted by the radiant heating and cooling device 12 at a position above the coverings 32, 34, and 37 can flow down from the protruding side end along the upper surfaces of the coverings 32, 34, and 37, and air (warm air) temperature-adjusted by the radiant heating and cooling device 12 at a position below the coverings 32, 34, and 37 can be retained on the curved lower surfaces of the coverings 32, 34, and 37 to prevent the air from escaping. This allows a comfortable thermal environment to be created in the room space 1 using the air temperature-adjusted by the radiant heating and cooling device 12. Furthermore, the undersides of the covering bodies 32, 34, 37 that protrude forward from the surface of the wall portion 4 are curved upward in a side cross-sectional view, so that the user P who uses the space below the covering bodies 32, 34, 37 feels as if the space below them has expanded upward. This makes it less likely that the user will feel oppressive compared to, for example, when the undersides of the covering bodies 32, 34, 37 are flat ceiling surfaces that are not curved, so it is possible to ensure a moderately enclosed space with a reduced sense of oppression.

[0008] The invention described in claim 2 is, for example, as shown in Figs. 13 to 16, an air conditioning system for the room space 1 described in claim 1, The undersides of the covering bodies 32, 34, and 37 are a first curved region 32b, 34b, 37b that gradually curves upward from a lower end 32d, 34d, 37d at the base end of the covering body 32, 34, 37 toward the highest vertex 32a, 34a, 37a of the lower surface; a second curved region 32c, 34c that gradually curves downward from the apex 32a, 34a, 37a toward a lower end 32e, 34e at the tip of the covering body 32, 34, 37; The present invention is characterized in that the electrode is formed in a state having the above structure.

[0009] According to the invention described in claim 2, the underside of the covering body 32, 34, 37 is formed to have a first curved region 32b, 34b, 37b that gradually curves upward from the lower end 32d, 34d, 37d at the base end of the covering body 32, 34, 37 toward the highest vertex 32a, 34a, 37a on the underside, and a second curved region 32c, 34c that gradually curves downward from the vertex 32a, 34a, 37a toward the lower end 32e, 34e at the tip end of the covering body 32, 34, 37, so that the underside of the covering body 32, 34, 37 can be formed to be curved upward when viewed in cross section from the side.

[0010] The invention described in claim 3 can be implemented as follows, for example, as shown in FIG. 2 In the air conditioning system for the room space 1 described above, The cover 37 is characterized in that both widthwise side edges 37f of the cover 37 are positioned lower than the apex 37a.

[0011] According to the invention described in claim 3, the covering body 37 is formed such that both widthwise end portions 37f of the covering body 37 are positioned lower than the apex 37a, so that for a user P using the space below the covering body 37, the sides of the space below are covered by both widthwise end portions 37f of the covering body 37. As a result, the underside of the covering body 37 is formed almost dome-shaped, ensuring a moderately enclosed space with reduced oppressive feeling.

[0012] The invention described in claim 4 is, for example, as shown in FIG. 16, an air conditioning system for the room space 1 described in claim 3, The cover 37 has a plurality of slits 37g formed therein, which penetrate the cover 37 in the thickness direction. The plurality of slits 37g are characterized in that they connect the upper space and the lower space of the cover 37 to each other.

[0013] According to the invention described in claim 4, the covering body 37 is formed with a plurality of slits 37g that penetrate the covering body 37 in the thickness direction, and the plurality of slits 37g connect the upper and lower spaces of the covering body 37, so that air and lines of sight can escape in the vertical direction through the plurality of slits 37g, thereby ensuring an appropriate enclosed space that is less likely to feel oppressive. Furthermore, air (cold air) whose temperature has been adjusted by the radiant heating and cooling device 12 at a position above the covering body 37 can be circulated directly below the covering body 37 through multiple slits 37g, and air that does not enter the multiple slits 37g can be made to flow down from the end on the protruding direction side along the upper surface of the covering bodies 32, 34, and 37. Moreover, the air (warm air) whose temperature has been adjusted by the radiant heating and cooling device 12 at a position below the coverings 32, 34, and 37 can be temporarily retained on the underside of the covering 37 and then circulated through the multiple slits 37g directly above the third covering 37. This allows the heat in the space below the covering 37 to be gradually released while warming the space below the covering 37, thereby preventing heat from building up in the enclosed space.

[0014] The invention described in claim 5 is, for example, as shown in FIG. 15, an air conditioning system for a room space 1 according to any one of claims 1 to 4, The housing further includes a wall body 35 that is in contact with the wall surface of the wall portion 4 and has an upper end portion located below the lower surface of the covering body 34, The wall 35 is characterized in that an illumination device 36 that emits light upward is provided at the upper end thereof.

[0015] According to the invention described in claim 5, the lighting device 36 that emits light upward is provided at the upper end of the wall body 35 that is in contact with the wall surface of the wall portion 4 and is located below the underside of the covering body 34, so that the lighting device 36 can illuminate the space below the covering body 34 as indirect lighting. The light emitted from the lighting device 36 becomes soft light when it hits the underside of the covering body 34, so the space below the covering body 34 feels less oppressive and becomes a more calming space, improving comfort as a space to be enclosed.

[0016] The invention described in claim 6 is, for example, as shown in FIG. 15, an air conditioning system for a room space 1 according to any one of claims 1 to 4, The housing further includes a wall body 35 that is in contact with the wall surface of the wall portion 4 and has an upper end portion located below the lower surface of the covering body 34, The wall 35 is characterized in that an acoustic device that emits sound upward is provided at the upper end thereof.

[0017] According to the invention of claim 6, an acoustic device that emits sound upward is provided at the upper end of the wall body 35 that is in contact with the wall surface of the wall portion 4 and is located below the underside of the covering body 34, so that the sound emitted upward from the acoustic device reverberates in the space below the covering body 34 and is less likely to leak from the space below the covering body 34. On the other hand, external sounds are less likely to reach the user P who uses the space below the covering body 34, so the comfort of the enclosed space can be improved in terms of acoustics as well. [Effects of the Invention]

[0018] According to the present invention, a comfortable thermal environment can be created within a room space by utilizing air whose temperature has been adjusted by a radiant heating and cooling device, while also ensuring a moderately enclosed space with a reduced feeling of oppression.

[0020] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are subject to various limitations that are technically preferable for carrying out the present invention, but the technical scope of the present invention is not limited to the following embodiments and illustrated examples. Note that the embodiments described below may be combined as much as possible.

[0021] First Embodiment In Fig. 1, reference numeral 1 denotes a room space. This room space 1 is the interior space of a room in which bedding 10 is installed, such as a master bedroom, a children's room, or a guest room in a house. The room space 1 is surrounded by a floor 2, a ceiling 3, and a plurality of walls 4.

[0022] The floor section 2 is provided continuous with the floor body on the same floor in the house, and in this embodiment it is provided integrally with the floor body on the same floor, but it may also be formed integrally with the floor body on the same floor. In this embodiment, the floor portion 2 is set to the same height across the entire surface, but may have uneven portions such as a skip floor, a raised area, or a sunken kotatsu. In addition, a rug such as a tile carpet may be laid on the upper surface of the floor part 2 to prevent scratches caused by the legs of the bedding 10.

[0023] The ceiling section 3 is located above the floor section 2 and is designed to have a ceiling height equivalent to that of other rooms in the house, such as living rooms, but this is not the case in the case of an open-plan space or a low-ceilinged room such as a loft. The ceiling portion 3 in this embodiment is set to the same height across the entire surface, but may be a sloped ceiling or a raised ceiling.

[0024] The multiple walls 4 are arranged between the floor 2 and the ceiling 3, and separate the room space 1 from other rooms or the outdoors. The multiple walls 4 may be provided continuous with walls that form other rooms in the house. Furthermore, the multiple walls 4 may be provided as interior walls within the house, or as exterior walls that form the perimeter of the house. At least one of the plurality of wall portions 4 has an opening (not shown) for entering and exiting the room space 1. The plurality of wall portions 4 may also have an opening (not shown) that communicates with the outdoors.

[0025] The room space 1 is equipped with bedding 10 and a radiant heating and cooling device 12.

[0026] In this embodiment, the bedding 10 is a bed that supports a user P with the user's head positioned at one end 10a and the feet positioned at the other end 10b. The bed 10 has a mattress placed on a base body, and hereinafter, the upper surface of the bed refers to the upper surface of the mattress. The thickness of the mattress can be changed as appropriate. Pillows, comforters, etc. can also be used as appropriate in combination with the bed 10.

[0027] The bed 10 is installed in the room space 1 with one end 10a, where the head of the user P is located, close to one of the multiple walls 4. In other words, the first wall 4a can be used in place of a headboard. The part of the wall surface of the first wall 4a to which the bed 10 is close may be given a finish (wallpaper, etc.) that is different from the surrounding area of ​​that part, so that it can be easily recognized that it can be used in place of a headboard. The bed 10 may also be fixed to the floor 2 or the wall 4. In other words, the bed 10 may be a built-in bed.

[0028] The multiple wall portions 4 include a first wall portion 4a arranged with one end 10a of the bed 10 brought together, a second wall portion 4b perpendicular to the first wall portion 4a in a plan view, and other wall portions not shown.

[0029] As the bedding 10, a futon, a hammock, a sleeping bag, or the like may be used in addition to the bed 10, but in any case, one end 10a where the head of the user P is located is set up against one of the walls 4. A raised area may be provided on the floor 2, and a futon may be placed on the raised area to be used in the same way as the bed 10.

[0030] The radiant heating and cooling device 12 is a device that radiates heat from the surface by circulating a high-temperature or low-temperature fluid through the internal pipe material 13a, and is incorporated and supported by the first wall portion 4a, which is arranged with one end 10a of the bed 10 pushed together. The fluid may be, for example, water or antifreeze (e.g., ethylene glycol). Water is easy to heat and cool, and is also a suitable fluid for maintenance of piping and the like. The first wall 4a incorporating the radiant air conditioner 12 functions as a support for supporting the radiant air conditioner 12. The radiant air conditioner 12 may be incorporated into the second wall 4b, in which case the second wall 4b also functions as a support. Furthermore, in this embodiment, the radiant heating and cooling device 12 is built into the wall 4, but this is not limited to this, and the radiant heating and cooling device 12 may also be built into the floor 2 or ceiling 3. In other words, the floor 2 and ceiling 3 may function as support bodies, or the radiant heating and cooling device 12 may be built into the floor 2 or ceiling 3 with the wall 4 acting as a support body.

[0031] As described above, the radiant air conditioner 12 is integrated into the first wall portion 4a. Therefore, the first wall portion 4a may refer to both the wall body of the first wall portion 4a and the radiant air conditioner 12. Therefore, the bed 10 is placed alongside such a radiant heating and cooling device 12. Although the first wall portion 4a has no openings, this only refers to a state in which there are no openings in the area where the radiant heating and cooling device 12 is installed, and openings may be formed in areas where the radiant heating and cooling device 12 is not installed. Furthermore, the finish of wallpaper or the like may be different from that of the other wall portions of the plurality of wall portions 4 so that it is easy to tell that the radiant cooling and heating device 12 is installed in the first wall portion 4a.

[0032] The radiant heating and cooling device 12 is disposed on the first wall portion 4a above the upper surface of the bed 10. If the radiant heating and cooling device 12 is disposed below the upper surface of the bed 10, condensation may occur due to the temperature difference with the mattress, so it is desirable to dispose the radiant heating and cooling device 12 above the upper surface of the bed 10. The height position of the upper surface of the bed 10 can be changed by changing the mattress used in the bed 10 to one with a different thickness, so the mattress can be used to position the radiant heating and cooling device 12 higher than the upper surface of the bed 10. Alternatively, the base of the bed 10 may have a height adjustment function.

[0033] To explain the configuration of the radiant heating and cooling device 12 in more detail, it comprises multiple heating and cooling panels 13 with pipes 13a through which cold or hot water flows, and multiple circulation pipes for circulating the cold or hot water between the panels and a water source. The circulation pipes run, for example, under the floor or above the ceiling, connecting the multiple heating and cooling panels 13 to the water source. The water supply source is connected to a heat exchange unit, which allows cold water to be circulated to the radiant air conditioner 12 in the summer and hot water to be circulated to the radiant air conditioner 12 in the winter. Furthermore, if the plurality of cooling and heating panels 13 are each supplied with fluid from a different system, it becomes possible to adjust the temperature of each cooling and heating panel 13 differently.

[0034] When such a radiant heating and cooling device 12 is incorporated into the first wall portion 4a, a plurality of heating and cooling panels 13 are incorporated into the frame that constitutes the first wall portion 4a. That is, if the skeleton of the house having the room space 1 is constructed using conventional construction methods, the first wall portion 4a will be composed of pillars, beams, etc. The multiple heating and cooling panels 13 may be directly attached to the skeleton such as pillars and beams, or may be attached to a frame fixed to the skeleton. Furthermore, the multiple walls 4 will be filled with insulating material, and the multiple heating and cooling panels 13 will be installed adjacent to that insulating material. When the skeleton of a house having the room space 1 is constructed using, for example, a framed wall construction method, a plurality of heating and cooling panels 13 are incorporated between wooden pieces assembled in a frame shape. The radiant heating and cooling device 12 incorporated into the structure that constitutes the first wall portion 4a is shielded by the surface material that constitutes the wall surface of the first wall portion 4a on the room space 1 side, and is not exposed to the room space 1.

[0035] The user P can be warmed or cooled by the direct radiant heat from the radiant heating and cooling device 12. Therefore, when one end 10a of the bed 10 is positioned close to the first wall 4a, the head of the user P located on the one end 10a side of the bed 10 is more likely to be directly affected by the radiant heat from the radiant heating and cooling device 12, while the feet of the user P located on the other end 10b side of the bed 10 are less likely to be directly affected by the radiant heat from the radiant heating and cooling device 12.

[0036] Furthermore, the temperature of the air near the radiant heating and cooling device 12 is adjusted by the radiant heat from the radiant heating and cooling device 12. The temperature-adjusted air can then heat or cool the room space 1 by natural convection within the room space 1. That is, if the user P is near the radiant heating and cooling device 12, he or she can be warmed or cooled by the direct radiant heat from the radiant heating and cooling device 12, and even if the user P is far from the radiant heating and cooling device 12, he or she can be warmed or cooled by the natural convection within the room space 1. In other words, if the air flow (air current) within the room space 1 can be controlled, the radiant heat emitted from the radiant heating and cooling device 12 can be transported farther.

[0037] In this embodiment, the radiant heating and cooling device 12 is incorporated into and supported by the first wall portion 4a of the multiple wall portions 4 that make up the room space 1, but it may also be incorporated into and supported by a false wall 5 formed on the wall surface of the first wall portion 4a, as shown in Figure 2. The raised wall 5 comprises a frame (not shown) that constitutes the raised wall 5, a face material that constitutes the wall surface of the raised wall 5 facing the room space 1, and a heating and cooling panel 13 having pipe material 13a through which high-temperature or low-temperature fluid flows. The heating and cooling panel 13 is provided on the back side of the face material and supported by the frame. This allows the radiant heating and cooling device 12 to be incorporated into and supported by the raised wall 5. The raised wall 5 is formed on the wall surface of the first wall portion 4a and is positioned to protrude forward of the first wall portion 4a, so that if one end 10a of the bed 10 is positioned close to it, it will be easily recognized by the user P as a headboard.

[0038] 2, by providing two false walls 5 (radiant heating and cooling devices 12) in the room space 1, it is possible to set different temperatures for the radiant heating and cooling device 12 in contact with one bed 10 (for example, the husband's bed) and the radiant heating and cooling device 12 in contact with the other bed 10 (for example, the wife's bed). If a couple has different temperatures that they find comfortable, the room temperature in the room space 1 can become a source of arguments, but by installing multiple radiant heating and cooling devices 12, personal air conditioning that realizes a comfortable temperature for each user P becomes possible, making it possible to avoid such arguments.

[0039] An air conditioning system including a radiant heating and cooling device 12 is installed in the room space 1 configured as above.

[0040] [Example] The air conditioning system for the room space 1 in this embodiment will be described in more detail below. It should be noted that each embodiment of the air conditioning system described below is premised on having the above-described configuration of the room space 1. Common elements are given common reference numerals, and descriptions thereof will be omitted or simplified as appropriate.

[0041] Example 1-1 As shown in Figure 3, the room space 1 of this embodiment is equipped with a first airflow control means 14 that is arranged on the side of the first wall portion 4a, which is the support body, and that controls the flow of air in the room, the temperature of which has been adjusted by radiant heat from the radiant heating and cooling device 12, in multiple patterns.

[0042] More specifically, the first airflow control means 14 in this embodiment is an air blowing device 14 that has a function of blowing air toward the room space 1. In this embodiment, a plurality of air blowing devices 14 are provided on the first wall portion 4a. These plurality of air blowing devices 14 are arranged at intervals in the vertical direction.

[0043] Each air blowing device 14 has an outlet 14a for blowing air toward the room space 1, and the main body of each air blowing device 14 that blows air is placed behind the first wall portion 4a, with only the outlet 14a exposed to the room space 1. The air outlet 14a can adjust the air volume and speed by changing the airflow direction up, down, left, and right and by narrowing or widening the opening range. That is, although not shown, the air outlet 14a is assumed to be appropriately provided with a plurality of fins for changing the airflow direction and shutters for narrowing or widening the opening range. The operation of the air outlet 14a may be automatically controlled or may be manually adjustable. In addition, the main body of the air blowing device 14 can adjust the volume of air. The air blowing device 14 may also have functions such as an on timer and an off timer. A remote control for controlling the operation of the air blowing device 14 may be provided.

[0044] In this embodiment, the air outlet 14a is set to a width corresponding to two beds 10 placed at a distance from each other, but the width may be set to correspond to each bed 10, and an air outlet 14a (air blowing device 14) may be provided for each bed 10. That is, by disposing the air outlets 14a (air blowing devices 14) separately on the left and right and placing the beds 10 in front of these left and right air outlets 14a (air blowing devices 14), personalization is enhanced. In other words, personal air conditioning that realizes a comfortable temperature for each user P using each of the left and right beds 10 is possible. When the radiant air conditioning device 12 is provided in the raised wall 5, the air outlet 14a is also provided in the raised wall 5.

[0045] In this embodiment, a plurality of radiant air conditioners 12 are provided on the first wall portion 4a. These plurality of radiant air conditioners 12 are arranged at intervals in the vertical direction. That is, a plurality of radiant air conditioners 12 and a plurality of first airflow control means 14 are incorporated into and supported by the first wall portion 4a. The plurality of radiant air conditioners 12 and the plurality of first airflow control means 14 are arranged alternately in the vertical direction. In the example shown in Fig. 3, a radiant air conditioner 12 is provided at the bottom and another radiant air conditioner 12 is provided at the top, and two radiant air conditioners 12 and three air blowing devices 14 (air outlets 14a) are arranged alternately between these radiant air conditioners 12.

[0046] The multiple radiant heating and cooling devices 12 have the same fluid supply system and generate radiant heat at the same temperature, but the set temperature may be changed for each of the radiant heating and cooling devices 12 arranged vertically.

[0047] The air conditioning system configured as described above can heat or cool objects located nearby by direct radiant heat from the multiple radiant heating and cooling devices 12. Furthermore, the temperature of the air near the multiple radiant heating and cooling devices 12 is adjusted by radiant heat from the multiple radiant heating and cooling devices 12. The temperature-adjusted air can then be sent to positions far from or close to the first wall portion 4a by the multiple air blowing devices 14, which are the first airflow control means. Furthermore, by adjusting the airflow direction and air volume for each of the multiple air blowing devices 14 (air outlets 14a), it is possible to control the airflow in a wider variety of patterns. This allows the temperature-adjusted air to be circulated to various locations within the room space 1. In addition, if the set temperature is changed for each of the multiple radiant heating and cooling devices 12 arranged vertically, air conditioning can be controlled in a more complex pattern.

[0048] One of the multiple patterns for controlling the flow of air whose temperature has been adjusted by the radiant heat from the multiple radiant heating and cooling devices 12 using the air blowing device 14 may include a pattern for stopping the operation of the air blowing device 14. In other words, the air blowing device 14 can control the flow of air in at least two patterns: by operating it or by stopping it.

[0049] Since the bed 10 is positioned with one end 10a close to the first wall 4a, the head of a user P of the bed 10 is heated or cooled by direct radiant heat from the radiant heating and cooling device 12. The feet of the user P, which are located at the other end 10b of the bed 10, are less affected by direct radiant heat from the radiant heating and cooling device 12, but are heated or cooled by the temperature-adjusted air sent by the air blowing device 14. In other words, the air conditioning system for the room space 1 can not only air condition the entire room space 1, but also contribute to creating a good sleeping environment in the bed 10, which is positioned with one end 10a close to the first wall portion 4a.

[0050] In this embodiment, the first airflow control means 14 is an air blowing device 14, but it is not limited to this and may be, for example, part of a ventilation system installed in a building, or an air conditioner that can adjust the temperature and humidity of the air in the room space 1. Furthermore, although a plurality of air blowing devices 14 are provided in this embodiment, it is also possible to use a single air blowing device 14. In this case, in order to control the air flow in the room space 1 in a plurality of patterns, a plurality of air outlets 14a are provided, and these plurality of air outlets 14a and the single air blowing device 14 are connected by a duct. Furthermore, since the air blowing device 14 is housed within the first wall portion 4a, when the first wall portion 4a (or the upper wall 5) is used as a headboard of the bed 10 and the user P uses it as a backrest, the air blowing device 14 does not get in the way.

[0051] Example 1-2 As shown in Figures 4 to 6, the room space 1 of this embodiment is equipped with a second airflow control means 15 that is arranged on the side of the first wall portion 4a, which is the support body, and that controls the flow of air in the room, the temperature of which has been adjusted by radiant heat from the radiant heating and cooling device 12, in multiple patterns.

[0052] More specifically, the second airflow control means 15 in this embodiment is a counter 15 provided to protrude from the wall surface of the first wall portion 4a. The counter 15 is provided at a height position higher than the upper surface of the bed 10. The bed 10 is also installed so that one end 10a is located below the counter 15. In other words, the counter 15 is located above the head of the user P.

[0053] The counter 15 is made of a rectangular plate material, and the longitudinal dimension of the plate material is set to be approximately equal to the width dimension of the bed 10.

[0054] The counter 15 is provided on the wall surface of the first wall portion 4a so as to be movable up and down along the wall surface of the first wall portion 4a. That is, a pair of guide rails 16 are provided on the wall surface of the first wall portion 4a, and a support slider 17 that slides along the guide rail 16 is provided on each of the pair of guide rails 16. The guide rail 16 is attached to the wall surface of the first wall portion 4a at a position such that the lower end can be disposed above the upper surface of the bed 10 with a gap therebetween.

[0055] The counter 15 is provided between support sliders 17 provided on a pair of guide rails 16 and is supported by these support sliders 17 . In this embodiment, the end of the counter 15 on the side of the first wall portion 4 a in the horizontally disposed state is connected to the support slider 17 .

[0056] The support slider 17 can be temporarily fixed at any position in the length direction of the guide rail 16. That is, the support slider 17 has a stopper (not shown) that contacts the guide rail 16, and when the stopper is in contact with the guide rail 16, the support slider 17 is temporarily fixed at any position in the length direction of the guide rail 16. Therefore, the counter 15 can be temporarily fixed at any position in the length direction of the guide rail 16.

[0057] Furthermore, the counter 15 is supported by a pair of support sliders 17 so as to be rotatable in the vertical direction, and is configured so that its angle can be adjusted relative to the wall surface of the first wall portion 4a. That is, when used as the counter 15, the counter 15 is disposed in a state in which it protrudes forward from the wall surface of the first wall portion 4a, but because the angle is adjustable, it can also be rotated upward or downward so that it fits along the wall surface of the first wall portion 4a. In this embodiment, the support slider 17 comprises a slider body that slides along the guide rail 16, a fixed part that is fixed to the side end face of the counter 15, and an angle adjustment part that is provided between the slider body and the fixed part. In a side view, the angle adjustment part rotates the fixed part relative to the slider body and has a configuration (mechanism) that temporarily fixes the rotation of the fixed part at any position in the rotation direction. A stopper may be provided as appropriate. However, this is not limited to this, and the angle adjustment of the counter 15 relative to the wall surface of the first wall portion 4a may be limited to two types: an angle at which the counter 15 is positioned horizontally, and an angle at which the counter 15 is rotated downward to be in line with the wall surface of the first wall portion 4a (in other words, a folded state).

[0058] As shown in Figure 5, items such as a smartphone SP or an alarm clock AC are placed on the top surface of the counter 15 and used, but if the counter 15 is rotated downward so that it is aligned with the wall surface of the first wall portion 4a without realizing that an item has been placed thereon, the item will naturally fall. Therefore, the upper surface of the counter 15 is provided with a function for attaching items. For this purpose, an adhesive sheet that repeatedly attaches items or a magnetic sheet that attaches metal parts of items may be appropriately used. Also, a hook-and-loop fastener or the like may be used to perform the attachment function not only on the upper surface of the counter 15 but also on the item side.

[0059] The vertical movement and angle adjustment of the counter 15 are performed automatically or manually. When performed automatically, the second airflow control means 15 includes a drive unit 18 for automatically moving the counter 15 up and down and adjusting the angle, as shown in Fig. 6. That is, the drive unit 18 has a first drive unit that slides the support slider 17 along the guide rail 16, and a second drive unit that rotates the counter 15 relative to the support slider 17.

[0060] Furthermore, the driving unit 18 is connected to a control device 19 constituted by a computer by wire or wirelessly, and is controlled by the control device 19. The control device 19 has a memory unit 20, which stores various programs and data necessary for controlling the drive unit 18. The control device 19 is also configured to control the drive unit 18 in accordance with the sensing results of a status detection sensor 21 provided in the room space 1.

[0061] Examples of the status detection sensor 21 include a sensor that detects the state of the air environment within the room space 1, such as temperature, humidity, and air cleanliness, a sensor that detects the illuminance under the counter 15, and a sensor (which may include a camera or microphone) that detects the biometric information of the user P (body temperature, blood pressure, blood flow, heart rate, complexion, sleep, breathing, sweating, etc.) without contact. In other words, the various programs stored in the memory unit 20 of the control device 19 include a program that is executed by the control device 19 when the sensing result of the status detection sensor 21 is input, and that operates the drive unit 18.

[0062] In addition, if the up and down movement and angle adjustment of the counter 15 are performed wirelessly, a communication network established within the building will be used, and the drive unit 18, control device 19, and status detection sensor 21 will be equipped with the necessary communication modules, etc. as appropriate.

[0063] According to the automatic control system for counter 15 configured in this way, when the sensing results of status detection sensor 21 satisfy certain conditions, a predetermined program stored in memory unit 20 of control device 19 is executed, and counter 15 can be slid along guide rail 16 or rotated relative to support slider 17. This allows counter 15 to be moved up and down and its angle to be adjusted automatically.

[0064] When manually moving the counter 15 up and down or adjusting the angle, the counter 15 is held by hand and slid upward or downward or rotated upward or downward. Once the position of the counter 15 is determined, the stopper is manually operated to temporarily fix the counter 15.

[0065] In this manner, the counter 15 can be moved up and down and its angle adjusted. The counter 15 is attached via guide rails 16 to the first wall portion 4a, which supports the radiant heating and cooling device 12.

[0066] In the air conditioning system for the room space 1 of this embodiment, direct radiant heat from the radiant heating and cooling device 12 can heat or cool objects located nearby. Furthermore, the temperature of the air near the radiant heating and cooling device 12 is adjusted by radiant heat from the radiant heating and cooling device 12. Of the air that has been temperature adjusted by the radiant heating and cooling device 12, the air that has been temperature adjusted at a position above the counter 15, which is the second airflow control means, is less likely to circulate directly below the counter 15. Furthermore, the air that has been temperature adjusted at a position below the counter 15, which is the second airflow control means, is less likely to circulate directly above the counter 15. Moreover, by moving the counter 15 up and down or adjusting its angle, it is possible to control the air flow in a wider variety of patterns. In addition, by changing the set temperature of the radiant heating and cooling device 12, it is possible to control the air conditioning in a more complex pattern.

[0067] To explain in more detail, cooled air has the tendency to descend. Air that has been temperature-adjusted above the counter 15 is less likely to circulate directly below the counter 15, so for people who dislike cold air hitting their face, the counter 15 can block the descending cold air as much as possible. The cool air blocked by the counter 15 descends from the protruding side end (and widthwise side end) of the counter 15, so it is more likely to flow toward the user P's toes than toward their head. By tilting the counter 15 downward, the speed at which the cool air descends can be improved. Conversely, by tilting the counter 15 upward, the descending cool air can be allowed to accumulate on the counter 15, and then slowly descend from the protruding side end of the counter 15 or the end on the first wall portion 4a side. Furthermore, if the height position of the counter 15 differs, the airflow control will differ depending on the height position. Furthermore, the airflow control will also differ depending on the set temperature of the radiant heating and cooling device 12.

[0068] On the other hand, heated air has the tendency to rise. Air that has been temperature-adjusted below the counter 15 is less likely to circulate directly above the counter 15, so for those who want to prevent warm air from escaping, the counter 15 can minimize the escape of rising warm air. Warm air that has been temperature-adjusted below the counter 15 gradually rises from the end of the counter 15 in the direction of projection, but by slanting the angle of the counter 15 downward, it becomes easier for the air to remain below the counter 15. Conversely, by slanting the angle of the counter 15 upward, it becomes easier for the rising warm air to escape slightly. Furthermore, if the height position of the counter 15 differs, the airflow control will differ depending on the height position. Furthermore, the airflow control will also differ depending on the set temperature of the radiant heating and cooling device 12.

[0069] One of the multiple patterns for controlling the flow of air whose temperature has been adjusted by radiant heat from the radiant heating and cooling device 12 using the counter 15 may include a pattern in which the counter 15 is rotated upward or downward to be aligned with the wall surface of the first wall 4a. That is, the counter 15 can control the flow of air in at least two patterns: either in a state in which it protrudes vertically from the wall surface of the first wall 4a, or in a state in which it is folded and aligned with the wall surface of the first wall 4a.

[0070] The air conditioning system for the room space 1 of this embodiment as described above can not only air condition the entire room space 1, but also contribute to creating a good sleeping environment in the bed 10, which is positioned with one end 10a close to the first wall portion 4a.

[0071] Although only one counter 15 is provided in this embodiment, multiple counters 15 may be provided at intervals in the vertical direction. In this case, by varying the protruding dimensions of the multiple counters 15 from the first wall portion 4a, it becomes possible to control the air flow in a wider variety of patterns.

[0072] Furthermore, the counter 15 can be slid up and down, so when the first wall portion 4a (or the raised wall 5) is used as the headboard of the bed 10 and the user P uses it as a backrest, the counter 15 can be slid up and out of the way.

[0073] Examples 1-3 As shown in Figure 7, the room space 1 of this embodiment is equipped with a third airflow control means 22 that is arranged on the side of the first wall portion 4a, which is the support body, and that controls the flow of air in the room, the temperature of which has been adjusted by radiant heat from the radiant heating and cooling device 12, in multiple patterns.

[0074] More specifically, the third airflow control means 22 in this embodiment is a sheet material 22 suspended from the ceiling 3 by wires 22a and 22b. The sheet material 22 is provided at a height position higher than the upper surface of the bed 10. The bed 10 is also installed such that one end 10a is located below the sheet material 22. In other words, the sheet material 22 is located above the head of the user P.

[0075] The material (fabric) of the sheet material 22 should not be selected to have a "mesh"-like texture, for example, with a coarse weave that allows a large amount of air to pass through, in order to control the airflow. Also, while high transparency or translucency is preferable in order to reduce the feeling of oppression, it is not necessary. In addition, a material with a certain degree of weight is preferable, since it becomes difficult to control the airflow if the material flutters significantly in the wind. It is desirable for the sheet material 22 used as the third airflow control means to satisfy these conditions. However, the material is not limited to this, and can be changed as appropriate according to the preferences of the user P, such as a patterned sheet material 22 or a sheet material 22 that is easy to wash.

[0076] The sheet material 22 is formed in a rectangular shape, and wires 22a and 22b are connected to the four corners. The upper end of each of the wires 22a and 22b is connected to a winding device (not shown). The winding device rotates automatically or manually, and can wind and unwind the wires 22a and 22b as it rotates. Of the sheet material 22, the wire 22a connected to the two corners on the first wall portion 4a side will be referred to below as the first wire 22a, and the wire 22b connected to the two corners on the opposite side to the first wall portion 4a will be referred to below as the second wire 22b. The first wire 22a and the second wire 22b are detachably connected to the four corners of the sheet material 22.

[0077] The sheet material 22 is suspended at its four corners by the first wires 22a and the second wires 22b, so that the parts other than the four corners are bent downward. In addition, a rod may be placed between the two corners of the sheet material 22 to which the first wire 22a is connected and between the two corners to which the second wire 22b is connected, to prevent the edge of the sheet material 22 on the first wall portion 4a side (one side edge) and the edge on the opposite side (other side edge) from bending.

[0078] The sheet material 22, which is the third airflow control means configured as described above, can be moved up and down and its angle adjusted by winding and unwinding the first wire material 22a and the second wire material 22b using the winding device described above. That is, the sheet material 22 can be moved up and down by unwinding the first wire material 22a and the second wire material 22b to lengthen them, or by retracting them to shorten them. Also, the angle of the sheet material 22 can be adjusted by unwinding either the first wire material 22a or the second wire material 22b to lengthen them, or by retracting them to shorten them.

[0079] The vertical movement and angle adjustment of the sheet material 22 are performed automatically or manually. When the winding is performed automatically, the winding device includes a drive unit for rotating the rotor around which the first wire rod 22a and the second wire rod 22b are wound. This drive unit can be controlled in a similar configuration to the above-mentioned automatic control system (see FIG. 6). That is, the drive unit is connected by wire or wirelessly to a control device configured by a computer, and is controlled by the control device according to a program stored in a memory unit. The control device is also configured to control the drive unit according to the sensing results of a status detection sensor 21 installed in the room space 1. According to the automatic control system for the sheet material 22 configured in this manner, when the sensing result by the state detection sensor 21 satisfies certain conditions, a predetermined program stored in the memory of the control device is executed, and the first wire 22a and the second wire 22b can be wound and unwound by the winding device as appropriate. This makes it possible to raise and lower one side edge of the sheet material 22 and raise and lower the other side edge, so that the vertical movement and angle adjustment of the sheet material 22 can be performed automatically.

[0080] When manually moving the sheet material 22 up and down and adjusting the angle, the winding device is used as a fixed pulley fixed to the ceiling 3, and the ends of the first wire 22a and the second wire 22b wound around the rotating body of the winding device are hung down. If rods are provided as weights on one and the other side edges of the sheet material 22 and fasteners are attached to the middle parts of the first wire 22a and the second wire 22b, the sheet material 22 will be positioned at a constant height, and this position can be set to the lowest position. To raise the sheet material 22, the ends of the first wire material 22a and the second wire material 22b hanging downward can be pulled downward. To temporarily fix the sheet material 22 in the raised position, the first wire material 22a and the second wire material 22b can be fastened to hooks protruding from the first wall portion 4a, for example.

[0081] In this manner, the sheet material 22 can be moved up and down and its angle adjusted. The radiant heating and cooling device 12 is incorporated and supported in the first wall portion 4a with the sheet material 22 disposed in front of it.

[0082] In the air conditioning system for the room space 1 of this embodiment, direct radiant heat from the radiant heating and cooling device 12 can heat or cool objects located nearby. Furthermore, the temperature of the air near the radiant heating and cooling device 12 is adjusted by radiant heat from the radiant heating and cooling device 12. Of the air whose temperature has been adjusted by the radiant heating and cooling device 12, the air whose temperature has been adjusted at a position above the sheet material 22, which is the third airflow control means, is less likely to circulate directly below the sheet material 22. Furthermore, the air whose temperature has been adjusted at a position below the sheet material 22, which is the third airflow control means, is less likely to circulate directly above the sheet material 22. Moreover, by moving the sheet material 22 up and down and adjusting its angle, it is possible to control the air flow in a wider variety of patterns. In addition, by changing the set temperature of the radiant heating and cooling device 12, it is possible to control the air conditioning in a more complex pattern.

[0083] More specifically, cooled air has a tendency to descend. Air that has been temperature-adjusted above the sheet material 22 is less likely to circulate directly below the sheet material 22, so for people who dislike cold air hitting their face, the sheet material 22 can block the descending cold air as much as possible. Because the sheet material 22 is not attached to the first wall portion 4a, the cool air blocked by the sheet material 22 descends from the peripheral edge of the sheet material 22. The cool air descending from the other side edge of the sheet material 22 is more likely to flow toward the toes of the user P than toward the head of the user P. By slanting the angle of the sheet material 22 downward (the other side edge is lower than the one side edge), the speed at which the cool air descends toward the toes of the user P can be increased. Conversely, by slanting the angle of the sheet material 22 upward (the other side edge is higher than the one side edge), the speed at which the cool air descends toward the head of the user P can be increased. Furthermore, if the height position of the sheet material 22 differs, the airflow control will differ depending on the height position. Furthermore, the airflow control will also differ depending on the set temperature of the radiant heating and cooling device 12.

[0084] On the other hand, heated air has the tendency to rise. Air that has been temperature-adjusted below the sheet material 22 tends to rise along the bending of the sheet material 22 and is less likely to stagnate below the sheet material 22. If you want to stagnate warm air below the sheet material 22, connect a pulling string (not shown) to the center of the sheet material 22, pull the string upward, and then tie the string to, for example, a hook protruding from the first wall portion 4a. This allows the sheet material 22 to expand upward, allowing warm air to stagnate below the sheet material 22. Furthermore, by tilting the sheet material 22 downward or upward, the warm air that has accumulated below the sheet material 22 can be gradually released upward. Furthermore, if the height position of the sheet material 22 differs, the airflow control will differ depending on the height position. Furthermore, the airflow control will also differ depending on the set temperature of the radiant heating and cooling device 12.

[0085] The air conditioning system for the room space 1 of this embodiment as described above can not only air condition the entire room space 1, but also contribute to creating a good sleeping environment in the bed 10, which is positioned with one end 10a close to the first wall portion 4a.

[0086] Although only one sheet material 22 is provided in this embodiment, multiple sheet materials 22 may be provided. In this case, by making the areas of the multiple sheet materials 22 different, it becomes possible to control the air flow in a wider variety of patterns.

[0087] Furthermore, the sheet material 22 can be moved in the vertical direction, so that when the first wall portion 4a (or the raised wall 5) is used as the headboard of the bed 10 and the user P uses it as a backrest, the sheet material 22 can be moved upward so that it does not get in the way.

[0088] In this embodiment, the sheet material 22 is formed in a rectangular shape with the wires 22a and 22b connected to the four corners, but this is not limited thereto and the sheet material 22 may be formed in another polygonal shape such as a triangular shape or a pentagonal shape with the wires 22a and 22b connected to the respective corners. In either case, however, in order to ensure the function as an airflow control means, it is desirable that the sides, not the corners, of the sheet material 22 be arranged along the wall surface of the first wall portion 4a.

[0089] Examples 1-4 As shown in Figure 8, the room space 1 of this embodiment is equipped with a fourth airflow control means 23 that is arranged on the side of the first wall portion 4a, which is the support body, and that controls the flow of air in the room, the temperature of which has been adjusted by radiant heat from the radiant heating and cooling device 12, in multiple patterns.

[0090] More specifically, the fourth airflow control means 23 in this embodiment is a curved counter 23 provided to protrude from the wall surface of the first wall portion 4a. The curved counter 23 is provided at a height position higher than the upper surface of the bed 10. The bed 10 is also installed so that one end 10a is located below the curved counter 23. In other words, the curved counter 23 is located above the head of the user P.

[0091] The curved counter 23 is curved so as to bulge downward in a side view, and the end portion of the curved counter 23 opposite the first wall portion 4a in the protruding direction faces upward. The width of the curved counter 23 is set to be approximately equal to the width of the bed 10.

[0092] The end of the bending counter 23 on the first wall 4a side is spanned across a plurality of supports 24 provided at intervals on the wall surface of the first wall 4a and is connected via a rotation shaft. That is, the bending counter 23 is rotatably supported by the plurality of supports 24 and is attached to the wall surface of the first wall 4a via these plurality of supports 24. This allows the bending counter 23 to rotate up and down and adjust its angle.

[0093] Although the bending counter 23 in this embodiment is configured to be angle adjustable, it may be configured to be vertically movable like the counter 15 described above.

[0094] The radiant heating and cooling device 12 is incorporated and supported on the first wall portion 4a to which the curved counter 23 as described above is attached.

[0095] In the air conditioning system for the room space 1 of this embodiment, direct radiant heat from the radiant heating and cooling device 12 can heat or cool objects located nearby. Furthermore, the temperature of the air near the radiant heating and cooling device 12 is adjusted by radiant heat from the radiant heating and cooling device 12. Of the air that has been temperature adjusted by the radiant heating and cooling device 12, the air that has been temperature adjusted at a position above the curved counter 23, which is the fourth airflow control means, is less likely to circulate directly below the curved counter 23. Furthermore, the air that has been temperature adjusted at a position below the curved counter 23, which is the fourth airflow control means, is less likely to circulate directly above the curved counter 23. Moreover, by adjusting the angle of the curved counter 23, it is possible to control the air flow in a wider variety of patterns. In addition, by changing the set temperature of the radiant heating and cooling device 12, it is possible to control the air conditioning in a more complex pattern.

[0096] More specifically, cooled air has a tendency to descend. Air that has been temperature-adjusted above the curved counter 23 is less likely to circulate directly below the curved counter 23, so for people who dislike cold air hitting their face, the curved counter 23 can block the descending cold air as much as possible. The cool air blocked by the curved counter 23 descends from the protruding side end (and widthwise side end) of the curved counter 23, so it is more likely to flow toward the user P's toes than toward their head. By tilting the angle of the curved counter 23 downward, the speed at which the cool air descends can be improved. In particular, since the protruding side end is in an upward position as described above, the cool air can be forcefully sent far away depending on the speed at which it descends. Conversely, by tilting the angle of the curved counter 23 upward, more of the descending cool air can be retained on the curved counter 23. The accumulated cool air can be slowly lowered from the protruding side end or the first wall portion 4a side end of the curved counter 23.

[0097] On the other hand, heated air has the tendency to rise. Air that has been temperature-adjusted below the curved counter 23 tends to rise along the curved shape of the curved counter 23 and is less likely to stagnate below the curved counter 23. In other words, the curved counter 23 has a shape that allows warm air to easily escape. By tilting the curved counter 23 upward, warm air can be released upward more quickly.

[0098] The air conditioning system for the room space 1 of this embodiment as described above can not only air condition the entire room space 1, but also contribute to creating a good sleeping environment in the bed 10, which is positioned with one end 10a close to the first wall portion 4a.

[0099] Although only one curved counter 23 is provided in this embodiment, multiple curved counters 23 may be provided. In this case, by making the protruding dimensions of the multiple curved counters 23 from the first wall portion 4a different, it becomes possible to control the air flow in more diverse patterns.

[0100] Examples 1-5 As shown in Figure 9, the room space 1 of this embodiment is equipped with a fifth airflow control means 25 that is arranged on the side of the first wall portion 4a, which is the support body, and that controls the flow of air in the room, the temperature of which has been adjusted by radiant heat from the radiant heating and cooling device 12, in multiple patterns.

[0101] More specifically, the fifth airflow control means 25 in this embodiment is a counter 25 that protrudes from the wall surface of the second wall 4b forward of the first wall 4a. The counter 25 is provided at a height position higher than the upper surface of the bed 10. The bed 10 is also installed so that one end 10a is located below the counter 25. In other words, the counter 25 is located above the head of the user P.

[0102] The counter 25 is made of a rectangular plate material, and its lower end is attached to the second wall 4b that is perpendicular to the first wall 4a in a plan view. The second wall 4b is formed with a storage recess 4c in which the counter 25 is stored, and the lower end of the counter 25 is attached to the lower end of the side edge of the storage recess 4c via a rotating shaft. In other words, the counter 25 is configured to rotate up and down around the rotating shaft at the lower end.

[0103] At the lowest position, the counter 25 abuts against the lower edge of the storage recess 4c and is positioned horizontally. An auxiliary bracket (not shown) that abuts against the wall surface of the second wall 4b like a knee brace may be attached to the underside of the counter 25. At the uppermost position, the counter 25 is stored in the storage recess 4c. A latch lock (not shown) is provided between the underside of the counter 25 (which is a vertical surface when stored) and the wall surface of the second wall 4b, so that the stored state can be maintained.

[0104] The second wall portion 4b to which the counter 25 described above is attached does not have a radiant heating and cooling device 12 built in, but the first wall portion 4a, which is perpendicular to the second wall portion 4b in a plan view, has a radiant heating and cooling device 12 built in and supported thereon.

[0105] In the air conditioning system for the room space 1 of this embodiment, direct radiant heat from the radiant heating and cooling device 12 can heat or cool objects located nearby. Furthermore, the temperature of the air near the radiant heating and cooling device 12 is adjusted by radiant heat from the radiant heating and cooling device 12. Of the air whose temperature is adjusted by the radiant heating and cooling device 12, the air whose temperature is adjusted at a position above the counter 25, which is the fifth airflow control means, is less likely to circulate directly below the counter 25. Furthermore, the air whose temperature is adjusted at a position below the counter 25, which is the fifth airflow control means, is less likely to circulate directly above the counter 25.

[0106] To explain in more detail, cooled air has the tendency to descend. Air that has been temperature-adjusted above the counter 25 is less likely to circulate directly below the counter 25, so for people who dislike cold air hitting their face, the counter 25 can block the descending cold air as much as possible. The cool air blocked by the counter 25 flows downward from the end of the counter 25 on the protruding side (and the end on the foot side of the user P), and therefore is more likely to flow toward the foot side of the user P than toward the head side.

[0107] On the other hand, heated air has the tendency to rise. Air that has been temperature-adjusted below the counter 25 is less likely to circulate directly above the counter 25, so for those who want to prevent warm air from escaping, the counter 25 can minimize the escape of rising warm air.

[0108] The air conditioning system for the room space 1 of this embodiment as described above can not only air condition the entire room space 1, but also contribute to creating a good sleeping environment in the bed 10, which is positioned with one end 10a close to the first wall portion 4a.

[0109] In this embodiment, the counter 25 can control the air flow in two patterns: either protruding perpendicularly from the second wall 4b or stored in the storage recess 4c and aligned with the wall surface of the second wall 4b. However, the counter 25 may be configured to have an adjustable angle. In this case, adjusting the angle of the counter 25 allows for more diverse control of the air flow.

[0110] Furthermore, the counter 25 can be stored in the storage recess 4c of the second wall 4b, so when the first wall 4a (or the raised wall 5) is used as the headboard of the bed 10 and the user P uses it as a backrest, the counter 25 can be stored in the storage recess 4c and will not get in the way.

[0111] Examples 1-6 As shown in Figure 10, the room space 1 of this embodiment is equipped with a sixth airflow control means 26 that is arranged on the side of the first wall portion 4a, which is the support body, and that controls the flow of air in the room, the temperature of which has been adjusted by radiant heat from the radiant heating and cooling device 12, in multiple patterns.

[0112] More specifically, the sixth airflow control means 26 in this embodiment is a counter 26 that protrudes from the wall surface of the first wall portion 4a. The counter 26 is provided at a height position higher than the upper surface of the bed 10. The bed 10 is also installed so that one end 10a is located below the counter 26. In other words, the counter 26 is located above the head of the user P.

[0113] The counter 26 is formed in a rectangular shape, and the longitudinal dimension is set to be approximately equal to the width dimension of the bed 10. Counter 26 is formed to be hollow, and cooling / heating panel 13 is provided in the hollow portion. That is, counter 26 functions as a radiant cooling / heating device.

[0114] The heating and cooling panel 13 provided in the hollow portion of the counter 26 is supplied with fluid through a system different from that of the heating and cooling panel 13 constituting the radiant heating and cooling device 12 that is incorporated into and supported by the first wall portion 4a. This makes it possible to control the temperature differently between the counter 26, which functions as a radiant heating and cooling device, and the radiant heating and cooling device 12 on the first wall portion 4a side.

[0115] The cooling and heating panel 13 provided in the hollow portion of the counter 26 has a circulation pipe that passes through the first wall portion 4a and is connected to a water supply source. Therefore, the counter 26 in this embodiment is configured so that it cannot be moved up and down or its angle can be adjusted.

[0116] In the air conditioning system for the room space 1 of this embodiment, objects located nearby can be heated or cooled by direct radiant heat from the radiant heating and cooling device 12. Also, objects located nearby can be heated or cooled by direct radiant heat from the counter 26, which functions as a radiant heating and cooling device. Furthermore, the temperature of the air near the radiant heating and cooling device 12 and the counter 26 is adjusted by radiant heat from the radiant heating and cooling device 12 and the counter 26. Of the air whose temperature is adjusted by the radiant heating and cooling device 12 and the counter 26, the air whose temperature is adjusted at a position above the counter 26 is less likely to circulate directly below the counter 26. Furthermore, the air whose temperature is adjusted at a position below the counter 26 is less likely to circulate directly above the counter 26.

[0117] In this embodiment, the air flow can be controlled by appropriately adjusting the temperature (including on / off) by the radiant heating and cooling device 12 and the temperature (including on / off) by the counter 26, which also functions as a radiant heating and cooling device.

[0118] To explain in more detail, by combining the operating states of the radiant heating and cooling device 12 alone in cooling or heating mode, the counter 26 functioning as a radiant heating and cooling device alone in cooling or heating mode, and both the radiant heating and cooling device 12 and the counter 26 in cooling or heating mode, and adjusting the temperature separately, it becomes possible to control the air flow in a variety of patterns without having to move the counter 26 up and down or adjust its angle.

[0119] The air conditioning system for the room space 1 of this embodiment as described above can not only air condition the entire room space 1, but also contribute to creating a good sleeping environment in the bed 10, which is positioned with one end 10a close to the first wall portion 4a.

[0120] Examples 1-7 11 shows an example of the arrangement of airflow control means for a plurality of cooling and heating panels 13 with pipes 13a arranged inside. The pipes 13a are arranged in a serpentine manner inside the cooling and heating panels 13. In addition, it is assumed that at least a surface material (construction board material such as plywood or fire-resistant covering material such as gypsum board) that constitutes the wall surface of the first wall portion 4a is interposed between the multiple heating and cooling panels 13 and the airflow control means.

[0121] The airflow control means shown in FIG. 11(a) is a counter 27 fixed to the wall surface of the first wall portion 4a, and is configured so as not to slide along the wall surface of the first wall portion 4a. When fixing such a counter 27 to the wall surface of the first wall portion 4a, the counter 27 itself or a bracket supporting the counter 27 is fixed to the surface material that constitutes the wall surface of the first wall portion 4a with fixing material B such as a screw. At this time, the fixing material B is driven in, avoiding the meandering pipe material 13a, as shown in Figure 11(a).

[0122] The airflow control means shown in Figure 11(b) is a counter that is movable up and down relative to the wall surface of the first wall portion 4a, and the counter is slidably mounted on a pair of guide rails 28 that are arranged and fixed along the vertical direction on the wall surface of the first wall portion 4a. When such a pair of guide rails 28 are fixed to the wall surface of the first wall portion 4a, the pair of guide rails 28 are fixed to the surface material that constitutes the wall surface of the first wall portion 4a by fixing materials B such as screws. At this time, the fixing materials B are driven in so as to avoid the meandering pipe material 13a, as shown in FIG. 11(b).

[0123] Examples 1-8 In this embodiment, as shown in Fig. 12, a non-contact thermometer 30 for measuring the body temperature of a user P is installed on a counter 29. In addition, a humidifier 31 is installed on the counter 29 to prevent the user P from becoming dry in winter. The counter 29 in this embodiment can be moved up and down and its angle adjusted as needed.

[0124] A recess 29a is formed on the underside of the counter 29, and the non-contact thermometer 30 and the humidifier 31 are housed and attached in the recess 29a. The non-contact thermometer 30 can be used not only for health management of the user P but also as the condition detection sensor described above. The humidifier 31 is not only used for health management of the user P and for countering dryness in winter, but can also be used as one function of the air conditioning system in the room space 1. That is, humidity can be adjusted by operating the humidifier 31. The humidifier 31 is provided as a set with a tank 31a that can be removed from the recess 29a.

[0125] By giving the airflow control means a health management function for user P in this way, it is preferable because it not only contributes to air conditioning the entire room space 1, but also to creating a good sleeping environment in the bed 10, which is positioned with one end 10a close to the first wall portion 4a.

[0126] In this embodiment, a non-contact thermometer 30 is used at the counter 29 to measure the body temperature of the user P, but instead of the non-contact thermometer 30, a biosensor (which may include a camera or microphone) may be used to detect the biometric information of the user P (body temperature, blood pressure, blood flow, heart rate, complexion, sleep, breathing, sweating, etc.) without contact.

[0127] Furthermore, in this embodiment, the humidifier 31 is provided on the counter 29, but a dehumidifier (not shown) may be provided instead of or together with the humidifier 31. By providing a dehumidifier, dehumidification can be performed during the summer and rainy season, contributing to the creation of a good sleeping environment.

[0128] According to this embodiment, the following excellent effects are achieved. That is, the airflow control means 14, 15, 22, 23, 25, 26, 27, and 29 control the airflow in the room space 1 in multiple patterns, preventing the airflow from becoming constant. This allows air whose temperature has been adjusted by radiant heat from the radiant heating and cooling device 12 to circulate widely within the room space 1, creating a comfortable thermal environment within the room space 1.

[0129] In addition, the air blowing device 14 that blows out air from the air outlet 14a is incorporated into and supported by the support body 4, and is arranged alongside the radiant heating and cooling device 12, so that the air whose temperature has been adjusted by the radiant heat from the radiant heating and cooling device 12 can be easily circulated widely within the room space 1 by the air blown out from the air outlet 14a of the air blowing device 14.

[0130] Furthermore, since the support 4 is the wall portion 4 that constitutes the room space 1, and the radiant cooling and heating device 12 and the air blowing device 14 are arranged side by side one above the other, cool air that has a tendency to descend and warm air that has a tendency to rise can be easily circulated widely within the room space 1 by the air blown out from the outlets 14a of the air blowing device 14. That is, for example, if the air blowing device 14 is arranged below the radiant cooling and heating device 12, cool air that has a tendency to descend can be easily circulated widely within the room space 1, and if the air blowing device 14 is arranged above the radiant cooling and heating device 12, warm air that has a tendency to rise can be easily circulated widely within the room space 1.

[0131] In addition, the airflow control means 15, 22, 23, 25, 26, 27, 29 are arranged in front of the support body 4 and are configured so that their position can be changed relative to the surface of the support body 4 facing the room space 1, so that air whose temperature has been adjusted by radiant heat from the radiant heating and cooling device 12 can be circulated within the room space 1 in accordance with the change in position of the airflow control means 15, 22, 23, 25, 26, 27, 29.

[0132] In addition, the angle of the counters 15, 23, 25, 26, 27, and 29 can be adjusted relative to the wall surface of the wall section 4, so that air whose temperature has been adjusted by radiant heat from the radiant heating and cooling device 12 can be circulated within the room space 1 according to the angle of the counters 15, 23, 25, 26, 27, and 29.

[0133] In addition, the counters 15, 23, 25, 26, 27, and 29 are movable vertically along the wall surface of the wall portion 4, so that air whose temperature has been adjusted by radiant heat from the radiant heating and cooling device 12 can be circulated within the room space 1 depending on the vertical position of the counters 15, 23, 25, 26, 27, and 29.

[0134] In addition, the counter 23 is curved so as to bulge downward in a side view, and the protruding end opposite the wall 4 faces upward, so by tilting the angle of the counter 23 downward, it becomes possible to forcefully send the descending cold air far away from the upward protruding end. Furthermore, by tilting the angle of the counter 23 upward, it becomes easier for a large amount of the descending cold air to remain on the counter 23.

[0135] In addition, the airflow control means 15, 23, 25, 26, 27, 29 are fixed directly or indirectly to the surface of the support body 4 facing the room space 1 by fixing material B, and the fixing material B is positioned to avoid the pipe material 13a of the heating and cooling panel 13 of the radiant heating and cooling device 12 incorporated in the support body 4, so that the airflow control means 15, 23, 25, 26, 27, 29 can be positioned in front of the radiant heating and cooling device 12 while preventing the fixing material B from damaging the pipe material 13a.

[0136] Furthermore, the sheet material 22, which is suspended from the ceiling 3 and positioned in front of the wall 4, can be moved vertically along the wall surface of the wall 4 and its angle can be adjusted relative to the wall surface of the wall 4, so that air whose temperature has been adjusted by radiant heat from the radiant heating and cooling device 12 can be circulated within the room space 1 according to the vertical position and angle of the sheet material 22.

[0137] In addition, the control device 19 controls the operation of the airflow control means 15, 22, 23, 25, 26, 27, and 29 according to the sensing results of the condition detection sensor 21 installed in the room space 1, making it possible to perform optimal control according to the condition of the room space 1 and automatically create a comfortable thermal environment in the room space 1.

[0138] Second Embodiment Next, a second embodiment will be described with reference to the drawings. For ease of explanation, elements common to the first embodiment will be denoted by the same reference numerals, and explanations thereof will be omitted or simplified.

[0139] The room space 1 in this embodiment is an internal space of a room in which bedding 10 is installed, such as a master bedroom (bedroom), a child's room, or a guest room in a house. The room space 1 is surrounded by a floor 2, a ceiling 3, and a plurality of walls 4. The room space 1 is equipped with bedding 10 and a radiant heating and cooling device 12. An air conditioning system including a radiant heating and cooling device 12 is installed in the room space 1 configured as above.

[0140] [Example] The air conditioning system for the room space 1 in this embodiment will be described in more detail below. It should be noted that each embodiment of the air conditioning system described below is premised on having the above-described configuration of the room space 1. Common elements are given common reference numerals, and descriptions thereof will be omitted or simplified as appropriate.

[0141] Example 2-1 In order to create a comfortable enclosed space when sleeping, the room space 1 of this embodiment is equipped with a first covering body 32 that is provided on the first wall portion 4a, which is a support body, and protrudes from the wall surface of the first wall portion 4a, as shown in Figure 13.

[0142] The lower surface of the first covering body 32 is curved upward when viewed in side cross section, and has a first curved region 32b that gradually curves upward from the lower end 32d at the portion on the first wall portion 4a side (base end) toward the other end 10b of the bed 10 to reach an apex 32a, and a second curved region 32c that gradually curves downward from the apex 32a toward the other end 10b of the bed 10 to reach a lower end 32e at the protruding direction side end (tip end). Furthermore, a lower end 32d at the base end of the first cover 32 and a lower end 32e at the end (tip end) of the first cover 32 in the protruding direction are at the same height position. When the lower surface of the first cover 32 is formed to be curved in this manner, it is preferable that the apex 32a is set to be located above the user P's head.

[0143] The portion (base end portion) of the first cover 32 on the first wall portion 4a side is provided integrally with the first wall portion 4a. The first cover 32 is configured to be as lightweight as possible, for example, by adopting a honeycomb structure or a flush structure so as to ensure a long protruding dimension from the first wall portion 4a. Furthermore, the base end side may be configured as a solid structure so that it can be firmly fixed to the first wall portion 4a, and the protruding direction side may be configured as a hollow structure to reduce weight. For example, when adopting a honeycomb structure or a flash structure, it is preferable to use hard paper or thin wood as the material, as this contributes to further weight reduction.

[0144] The upper surface of the first covering body 32 is provided with a counter plate 33 to form a horizontal surface on which items can be placed. The counter plate 33 also employs, for example, a honeycomb structure or a flush structure, and is constructed to be as lightweight as possible.

[0145] In this embodiment, the first covering body 32 is constructed to be as lightweight as possible, for example, by adopting a honeycomb structure or a flash structure, but this is not limited to this, and the first covering body 32 may be made flexible by adopting a flexible material such as rubber or other synthetic resin.

[0146] By forming and providing the first covering body 32 in the above manner, an enclosed space can be secured within the room space 1. In addition, side walls may be integrally formed at both widthwise ends of the first covering body 32 to enhance isolation from the outside, or there may be no side walls and the body may be open.

[0147] The radiant heating and cooling device 12 is incorporated and supported on the first wall portion 4a to which the first covering body 32 is attached. The first covering 32 also functions as an air diffusion means for diffusing the indoor air, the temperature of which has been adjusted by the radiant heat from the radiant heating and cooling device 12, to a location farther away from the radiant heating and cooling device 12.

[0148] In the air conditioning system for the room space 1 of this embodiment, direct radiant heat from the radiant heating and cooling device 12 can heat or cool objects located nearby. Furthermore, the temperature of the air near the radiant heating and cooling device 12 is adjusted by radiant heat from the radiant heating and cooling device 12. Of the air whose temperature is adjusted by the radiant heating and cooling device 12, the air whose temperature is adjusted at a position above the first covering 32 is less likely to circulate directly below the first covering 32. Furthermore, the air whose temperature is adjusted at a position below the first covering 32 is less likely to circulate directly above the first covering 32.

[0149] More specifically, cooled air has a tendency to descend. Air that has been temperature-adjusted above the first covering body 32 is less likely to circulate directly below the first covering body 32, so for people who dislike cold air hitting their face, the first covering body 32 can block the descending cold air as much as possible. The cool air blocked by the first covering body 32 flows downward from the protruding side end (and widthwise side end) of the first covering body 32, and is therefore more likely to flow toward the user P's toes than toward the head.

[0150] On the other hand, heated air has a tendency to rise. Air that has been temperature-adjusted below the first covering 32 is less likely to circulate directly above the first covering 32, so for those who want to prevent warm air from escaping, the first covering 32 can minimize the escape of rising warm air. In other words, warm air that has been temperature-adjusted below the first covering 32 is more likely to remain on the curved underside of the first covering 32, making it possible to minimize the escape of rising warm air.

[0151] The air conditioning system for the room space 1 of this embodiment as described above can not only air condition the entire room space 1, but also contribute to creating a good sleeping environment in the bed 10, which is positioned with one end 10a close to the first wall portion 4a. In particular, the section from the lower end 32d at the base end of the first cover 32 to the lower end 32e at the tip end is curved upward in a side view (side cross-sectional view), which allows the space to expand upward for the user P who places his / her head below. This makes it less likely that the user P will feel oppressive compared to, for example, a case in which the section from the lower end 32d at the base end of the first cover 32 to the lower end 32e at the tip end is a flat, uncurved ceiling surface. Therefore, it is possible to form a closed space that can adequately cover the head of the user P.

[0152] Although the first cover 32 in this embodiment is configured so as not to move up and down or adjust its angle, the present invention is not limited to this and may be provided so as to be movable up and down along the wall surface of the first wall 4a, or so as to be able to adjust its angle relative to the wall surface of the first wall 4a. Alternatively, the first cover 32 may be configured so as to be rotated upward and be able to adjust its angle so as to be in a state where it is aligned with the wall surface of the first wall 4a (in other words, in a folded state).

[0153] Example 2-2 In order to create a comfortable enclosed space when sleeping, the room space 1 of this embodiment is provided with a second covering body 34 that is provided on the first wall portion 4a, which is the support body, and protrudes from the wall surface of the first wall portion 4a, as shown in Figure 14.

[0154] The lower surface of the second covering body 34 is curved upward when viewed in side cross section, and has a first curved region 34b that gradually curves upward from the lower end 34d at the portion on the first wall portion 4a side (base end) toward the other end 10b of the bed 10 to reach an apex 34a, and a second curved region 34c that gradually curves downward from the apex 34a toward the other end 10b of the bed 10 to reach a lower end 34e at the protruding direction side end (tip end). Furthermore, a lower end 34d at the base end of the second cover 34 and a lower end 34e at the end (tip end) of the second cover 34 in the protruding direction are at the same height position. When the lower surface of the second cover 34 is formed to be curved in this manner, it is preferable that the apex 34a is set to be located above the user P's head.

[0155] The portion (base end portion) of the second cover 34 on the first wall portion 4a side is provided integrally with the first wall portion 4a. The second covering body 34 is constructed as light as possible, for example, by adopting a honeycomb structure or a flush structure so as to ensure a long protruding dimension from the first wall portion 4a. Furthermore, the base end side may be configured as a solid structure so that it can be firmly fixed to the first wall portion 4a, and the protruding direction side may be configured as a hollow structure to reduce weight. For example, when adopting a honeycomb structure or a flash structure, it is preferable to use hard paper or thin wood as the material, as this contributes to further weight reduction.

[0156] The upper surface of the second cover 34 is gradually curved downward from the first wall 4a side toward the tip end side. In other words, the upper surface of the second cover 34 slopes gently downward from the upper end at the portion on the first wall 4a side (base end) toward the end on the protruding direction side (tip end).

[0157] By forming and providing the second covering body 34 in the above manner, an enclosed space can be secured within the room space 1. In addition, side walls may be integrally formed at both widthwise ends of the second covering body 34 to enhance isolation from the outside, or there may be no side walls and the body may be open.

[0158] The radiant heating and cooling device 12 is incorporated and supported on the first wall portion 4a to which the second covering body 34 is attached. In addition, the second covering 34 also functions as an air diffusion means for diffusing the indoor air, the temperature of which has been adjusted by the radiant heat from the radiant heating and cooling device 12, to a location farther away from the radiant heating and cooling device 12.

[0159] In the air conditioning system for the room space 1 of this embodiment, direct radiant heat from the radiant heating and cooling device 12 can heat or cool objects located nearby. Furthermore, the temperature of the air near the radiant heating and cooling device 12 is adjusted by radiant heat from the radiant heating and cooling device 12. Of the air whose temperature is adjusted by the radiant heating and cooling device 12, the air whose temperature is adjusted at a position above the second covering 34 is less likely to circulate directly below the second covering 34. Furthermore, the air whose temperature is adjusted at a position below the second covering 34 is less likely to circulate directly above the second covering 34.

[0160] More specifically, cooled air has a tendency to descend. Air that has been temperature-adjusted above the second covering 34 is less likely to circulate directly below the second covering 34, so for people who dislike cold air hitting their face, the second covering 34 can block the descending cold air as much as possible. The cool air blocked by the second covering body 34 descends from the protruding side end (and widthwise side end) of the second covering body 34, and is therefore more likely to flow toward the toes of the user P than toward the head. In particular, the upper surface of the second covering body 34 is formed to gradually curve downward from the first wall portion 4a side toward the tip end side, and therefore the cool air is more likely to flow toward the toes of the user P than if the upper surface were formed horizontally.

[0161] On the other hand, heated air has a tendency to rise. Air that has been temperature-adjusted at a position below the second covering 34 is less likely to circulate directly above the second covering 34, so for those who want to prevent warm air from escaping, the second covering 34 can minimize the escape of rising warm air. In other words, warm air that has been temperature-adjusted at a position below the second covering 34 is more likely to remain on the curved lower surface of the second covering 34, so the escape of rising warm air can be minimized.

[0162] The air conditioning system for the room space 1 of this embodiment as described above can not only air condition the entire room space 1, but also contribute to creating a good sleeping environment in the bed 10, which is positioned with one end 10a close to the first wall portion 4a. In particular, the section from the lower end 34d at the base end of the second cover 34 to the lower end 34e at the tip end is curved upward in a side view (side cross section), which allows the space to expand upward for the user P who places his / her head below. This makes it less likely that the user P will feel oppressive compared to, for example, a case in which the section from the lower end 34d at the base end of the second cover 34 to the lower end 34e at the tip end is a flat, uncurved ceiling surface. Therefore, it is possible to form a closed space that can adequately cover the head of the user P.

[0163] Although the second cover 34 in this embodiment is configured so as not to move up and down or adjust its angle, the present invention is not limited to this and may be provided so as to be movable up and down along the wall surface of the first wall 4a, or so as to be able to adjust its angle relative to the wall surface of the first wall 4a. Alternatively, the second cover 34 may be configured so as to be rotated upward and be able to adjust its angle so as to be in a state where it is in a folded state along the wall surface of the first wall 4a.

[0164] FIG. 15 shows an example in which an illuminated wall body 35 that can be used as a headboard of the bed 10 is provided in contact with the wall surface of the first wall portion 4a. This illuminated wall 35 is erected on the floor 2 and fixed to the wall surface of the first wall 4a, but is not limited to this and may be integrally formed as a headboard on the base body of the bed 10.

[0165] The illuminated wall 35 has a recess 35a formed at its upper end, and a lighting device 36 is provided in the recess 35a. The upper opening of the recess 35a is closed by a light-transmitting lid 36a. An item can be placed on the top surface of the lid 36a. The recess 35a is formed on the first wall 4a side of the rising portion 35b located on the bed 10 side. As a result, the lighting device 36 provided in the recess 35a emits light upward through the lid 36a, illuminating the enclosed space as indirect lighting. That is, the light emitted from the lighting device 36 hits the underside of the second cover 34, creating a soft glow. As a result, the space below the second cover 34 feels less oppressive and more relaxed. In addition, because the underside of second covering 34 is curved, the light illuminating the enclosed space is less likely to leak outward (toward the feet) from the protruding end. This makes it difficult for the light from lighting device 36 to reach people outside second covering 34, which contributes to creating a comfortable sleeping environment for people outside second covering 34. Furthermore, since the lighting device 36 makes it possible to adjust the illuminance of the space below the second covering body 34, for example, by setting the lighting device 36 to emit light when waking up, the space below the second covering body 34 can be brightened, which also contributes to creating a good waking-up environment.

[0166] Note that an acoustic device (speaker) that emits sound may be provided at the upper end of the illuminated wall 35 instead of or in combination with the lighting device 36. In the case of an acoustic device, sound is also less likely to leak outward (toward the feet) from the protruding end. Therefore, sound from the acoustic device is less likely to reach people outside the second covering 34, which can contribute to creating a good sleeping environment for people outside the second covering 34. In addition, by using the lighting device 36 in combination with the audio device, for example, by setting the lighting device 36 to emit light and the audio device to emit sound when waking up, it is possible to help wake up comfortably.

[0167] Example 2-3 In order to create a comfortable enclosed space when sleeping, the room space 1 of this embodiment is equipped with a third covering body 37 that is provided on the first wall portion 4a, which is the support body, and protrudes from the wall surface of the first wall portion 4a, as shown in Figure 16.

[0168] Although not shown, the underside of the third covering body 37 has a first curved region 37b that gradually curves upward from the lower end 37d at the portion on the first wall portion 4a side (base end) toward the other end 10b of the bed 10, reaching an apex 37a, and a second curved region that gradually curves downward from the apex 37a toward the other end 10b of the bed 10, reaching the lower end at the protruding direction side end (tip end). The upper surface of the third cover 37 is formed to be gradually curved downward from the first wall portion 4a side toward the tip end side.

[0169] As shown in FIG. 16, both widthwise side edges 37f of the third cover 37 are located below the vertex 37a, which is the highest point on the underside of the third cover 37. More specifically, in the vertical cross section, the underside of the third covering body 37 in this embodiment curves upward and gradually curves downward from the apex 37a toward both widthwise end portions 37f. The widthwise end portions 37f are set at a height substantially equal to the lower end portion 37d at the base end and / or the lower end portion at the tip end of the third covering body 37. As a result, the underside of the third covering body 37 is dome-shaped in the side cross section and the vertical cross section, and the space below the third covering body 37 is highly isolated from the outside.

[0170] In this embodiment, the underside of the third cover 37 is curved upward in a vertical cross-sectional view, but this is not limited thereto and the underside does not have to be curved upward in a vertical cross-sectional view. That is, both widthwise end portions 37f of the third cover 37 may be formed with sidewall portions that hang down vertically. In this case, the third cover 37 is formed in a downward-facing U-shape (with the open part of the U-shape facing downward) in a vertical cross-sectional view.

[0171] Furthermore, the third cover 37 has a plurality of slits 37g formed therein, penetrating the third cover 37 in the thickness direction. The slits 37g connect the space above the third cover 37 with the space below it. Therefore, air and line of sight can escape in the vertical direction through the slits 37g.

[0172] The portion (base end portion) of the third cover 37 on the first wall portion 4a side is provided integrally with the first wall portion 4a. The third cover 37 is constructed as light as possible, for example, by adopting a honeycomb structure or a flush structure so as to ensure a long protruding dimension from the first wall portion 4a.

[0173] By forming and providing the third covering body 37 in the above manner, an enclosed space can be secured within the room space 1.

[0174] The radiant heating and cooling device 12 is incorporated and supported on the first wall portion 4a to which the third covering body 37 is attached. The third covering 37 also functions as an air diffusion means for diffusing the indoor air, the temperature of which has been adjusted by the radiant heat from the radiant heating and cooling device 12, to a location farther away from the radiant heating and cooling device 12.

[0175] In the air conditioning system for the room space 1 of this embodiment, direct radiant heat from the radiant heating and cooling device 12 can heat or cool objects located nearby. Furthermore, the temperature of the air near the radiant heating and cooling device 12 is adjusted by radiant heat from the radiant heating and cooling device 12. Cooled air has a tendency to descend. The air (cold air) whose temperature has been adjusted at a position above the third cover 37 flows through the multiple slits 37g to the area directly below the third cover 37. The cold air that does not enter the multiple slits 37g is blocked by the third cover 37 and flows along the upper surface of the third cover 37 toward the toes. On the other hand, heated air has the tendency to rise. The air whose temperature has been adjusted below the third covering body 37 temporarily stagnates on the curved underside of the third covering body 37, but then circulates directly above the third covering body 37 through the multiple slits 37g. This allows heat to escape from within the enclosed space, preventing heat from building up within the enclosed space.

[0176] The air conditioning system for the room space 1 of this embodiment as described above can not only air condition the entire room space 1, but also contribute to creating a good sleeping environment in the bed 10, which is positioned with one end 10a close to the first wall portion 4a. In particular, the widthwise side end portions 37f of the third cover 37 are positioned below the apex 37a, which is the highest point on the underside of the third cover 37, so that the space can expand upward for the user P who places his / her head below. Therefore, it is possible to form a closed space that can adequately cover the head of the user P. Furthermore, in this embodiment, the formation of multiple slits 37g further reduces the feeling of oppression. In addition, in this embodiment, the underside of the third covering body 37 is curved upward when viewed in vertical section, and gradually curves downward and slopes from the vertex 37a toward both widthwise ends 37f, so that the feeling of oppression is less likely to be felt compared to, for example, when the space between both widthwise ends of the third covering body 37 is a flat ceiling surface that is not curved.

[0177] Although the third cover 37 in this embodiment is configured so as not to move up and down or adjust its angle, the present invention is not limited to this and may be provided so as to be movable up and down along the wall surface of the first wall 4a, or so as to be able to adjust its angle relative to the wall surface of the first wall 4a. Alternatively, the third cover 37 may be configured so as to be rotated upward and be able to adjust its angle so as to be in a state where it is aligned with the wall surface of the first wall 4a (in other words, in a folded state).

[0178] Furthermore, the multiple slits 37g may be formed so that the slit width increases with increasing distance from the wall surface of the first wall 4a. Furthermore, the number of slits may increase with increasing distance from the wall surface of the first wall 4a. Furthermore, multiple through holes other than the slits 37g may be formed with increasing distance from the wall surface of the first wall 4a. This increases the area of ​​the openings formed in the third cover 37 with increasing distance from the wall surface of the first wall 4a, so that cool air whose temperature has been adjusted at a position above the third cover 37 can be evenly delivered to the toes of the user P.

[0179] According to this embodiment, the following excellent effects are achieved. That is, because the radiant heating and cooling device 12 is incorporated into and supported on the wall 4 to which the coverings 32, 34, 37 (first covering 32, second covering 34, third covering 37) are attached, objects located nearby can be heated or cooled directly by radiant heat from the radiant heating and cooling device 12. In addition, air (cold air) temperature-adjusted by the radiant heating and cooling device 12 at a position above the coverings 32, 34, 37 can flow down from the protruding side end along the upper surfaces of the coverings 32, 34, 37, and air (warm air) temperature-adjusted by the radiant heating and cooling device 12 at a position below the coverings 32, 34, 37 can be retained on the curved lower surfaces of the coverings 32, 34, 37 to prevent the air from escaping. This allows a comfortable thermal environment to be created in the room space 1 using the air temperature-adjusted by the radiant heating and cooling device 12. Furthermore, the undersides of the covering bodies 32, 34, 37 that protrude forward from the surface of the wall portion 4 are curved upward in a side cross-sectional view, so that the user P who uses the space below the covering bodies 32, 34, 37 feels as if the space below them has expanded upward. This makes it less likely that the user will feel oppressive compared to, for example, when the undersides of the covering bodies 32, 34, 37 are flat ceiling surfaces that are not curved, so it is possible to ensure a moderately enclosed space with a reduced sense of oppression.

[0180] Furthermore, the undersides of the covering bodies 32, 34, 37 (first covering body 32, second covering body 34, third covering body 37) are formed to have first curved regions 32b, 34b, 37b that gradually curve upward from the lower ends 32d, 34d, 37d at the base ends of the covering bodies 32, 34, 37 toward the highest vertices 32a, 34a, 37a on the undersides, and second curved regions 32c, 34c that gradually curve downward from the vertices 32a, 34a, 37a toward the lower ends 32e, 34e at the tip ends of the covering bodies 32, 34, 37, so that the undersides of the covering bodies 32, 34, 37 can be formed to be curved upward when viewed in cross section from the side.

[0181] Furthermore, the covering body 37 (third covering body 37) is formed such that both widthwise end portions 37f of the covering body 37 are positioned lower than the apex 37a, so that for a user P using the space below the covering body 37, the sides of the space below are covered by both widthwise end portions 37f of the covering body 37. As a result, the underside of the covering body 37 is formed almost dome-shaped, ensuring a moderately enclosed space with reduced oppressive feeling.

[0182] In addition, the covering body 37 (third covering body 37) has a plurality of slits 37g formed therein that penetrate the covering body 37 in the thickness direction, and the plurality of slits 37g connect the upper and lower spaces of the covering body 37, so that air and lines of sight can escape in the vertical direction through the plurality of slits 37g, thereby ensuring an adequately enclosed space that is less likely to feel oppressive. Furthermore, air (cold air) whose temperature has been adjusted by the radiant heating and cooling device 12 at a position above the covering body 37 can be circulated directly below the covering body 37 through multiple slits 37g, and air that does not enter the multiple slits 37g can be made to flow down from the end on the protruding direction side along the upper surface of the covering bodies 32, 34, and 37. Moreover, the air (warm air) whose temperature has been adjusted by the radiant heating and cooling device 12 at a position below the coverings 32, 34, and 37 can be temporarily retained on the underside of the covering 37 and then circulated through the multiple slits 37g directly above the third covering 37. This allows the heat in the space below the covering 37 to be gradually released while warming the space below the covering 37, thereby preventing heat from building up in the enclosed space.

[0183] Furthermore, a lighting device 36 that emits light upward is provided at the upper end of the wall 35 (illuminated wall 35) that is in contact with the wall surface of the wall portion 4 and is located below the underside of the covering body 34 (second covering body 34), so that the lighting device 36 can illuminate the space below the covering body 34 as indirect lighting. The light emitted from the lighting device 36 becomes a soft light when it hits the underside of the covering body 34, so the feeling of oppression in the space below the covering body 34 is reduced, making it a calm space and improving comfort as a space to be enclosed.

[0184] Furthermore, an acoustic device that emits sound upward is provided at the upper end of the wall 35 (illuminated wall 35) that is in contact with the wall surface of the wall portion 4 and is located below the underside of the covering body 34 (second covering body 34), so that the sound emitted upward from the acoustic device reverberates in the space below the covering body 34 and is less likely to leak from the space below the covering body 34. On the other hand, external sounds are less likely to reach the user P who uses the space below the covering body 34, so the comfort of the enclosed space can be improved in terms of acoustics as well.

[0185] Third Embodiment Next, a third embodiment will be described with reference to the drawings. For ease of explanation, elements common to the first and second embodiments will be denoted by the same reference numerals, and explanations thereof will be omitted or simplified.

[0186] The room space 1 in this embodiment is an internal space of a room in which bedding 10 is installed, such as a master bedroom (bedroom), a child's room, or a guest room in a house. The room space 1 is surrounded by a floor 2, a ceiling 3, and a plurality of walls 4. The room space 1 is equipped with bedding 10 and a radiant heating and cooling device 12. An air conditioning system including a radiant heating and cooling device 12 is installed in the room space 1 configured as above.

[0187] [Example] The air conditioning system for the room space 1 in this embodiment will be described in more detail below. It should be noted that each embodiment of the air conditioning system described below is premised on having the above-described configuration of the room space 1. Common elements are given common reference numerals, and descriptions thereof will be omitted or simplified as appropriate.

[0188] Example 3-1 17, the room space 1 of this embodiment is provided with a first air diffusion means 38 that is disposed on the side of the first wall portion 4a, which is the support body, and that diffuses the indoor air whose temperature has been adjusted by radiant heat from the radiant heating and cooling device 12. The first air diffusion means 38 has a passage portion 38a that allows for line of sight and air to pass through in the vertical direction.

[0189] More specifically, the first air diffusion means 38 in this embodiment is a counter 38 that protrudes from the wall surface of the first wall portion 4a. The counter 38 is provided at a height position higher than the upper surface of the bed 10. The bed 10 is also installed so that one end 10a is located below the counter 38. In other words, the counter 38 is located above the head of the user P.

[0190] The counter 38 is made up of a plurality of divided plates 38b spaced apart in the width direction on the wall surface of the first wall 4a. In this embodiment, three divided plates 38b are spaced apart in the width direction on the wall surface of the first wall 4a, and gaps 38a between these three divided plates 38b form passages 38a that allow line of sight and air to pass through in the vertical direction. The divided plate members 38b are made of rectangular plates, and the dimension from outer surface to outer surface of the divided plate members 38b on both sides is set to be approximately equal to the width dimension of the bed 10. The central divided plate member 38b is located above the center of the bed 10 in the width direction.

[0191] The radiant heating and cooling device 12 is incorporated and supported on the first wall portion 4a to which the counter 38 as described above is attached.

[0192] In the air conditioning system for the room space 1 of this embodiment, direct radiant heat from the radiant heating and cooling device 12 can heat or cool objects located nearby. Furthermore, the temperature of the air near the radiant heating and cooling device 12 is adjusted by radiant heat from the radiant heating and cooling device 12. Cooled air has a tendency to descend. The air (cold air) whose temperature has been adjusted at a position above the counter 38 flows through the multiple passages 38a between the multiple divided plates 38b to the area directly below the divided plates 38b (i.e., the counter 38). Furthermore, the cold air that does not enter the multiple passages 38a is blocked by the multiple divided plates 38b and flows along the upper surfaces of the multiple divided plates 38b to the side of the feet. On the other hand, heated air has the tendency to rise. Air (warm air) whose temperature has been adjusted below the counter 38 flows through the multiple passages 38a between the multiple dividing plates 38b to directly above the dividing plates 38b (i.e., the counter 38). Furthermore, the warm air that does not enter the multiple passages 38a is blocked by the multiple dividing plates 38b and temporarily stagnates on the undersides of the multiple dividing plates 38b, but then flows through the multiple passages 38a to directly above the multiple dividing plates 38b. This allows heat to escape from the space directly below the counter 38, preventing heat from building up in that space.

[0193] The air conditioning system for the room space 1 of this embodiment as described above can not only air condition the entire room space 1, but also contribute to creating a good sleeping environment in the bed 10, which is positioned with one end 10a close to the first wall portion 4a. In particular, counter 38 is made up of multiple divided plates 38b arranged at intervals from one another, and the gaps between the multiple divided plates 38b form passage sections 38a that allow line of sight and air to pass through in the vertical direction, so that a user P with their head positioned below the passage sections feels less oppressive than if line of sight and air passage were not possible. In addition, the multiple divided plates 38b can effectively diffuse cool air that has been temperature-adjusted above counter 38 and warm air that has been temperature-adjusted below counter 38.

[0194] Although the counter 38 in this embodiment is configured so as not to be movable up and down or have an adjustable angle, the present invention is not limited thereto and may be configured so as to be movable up and down along the surface of the first wall 4a, or so as to be adjustable in angle relative to the surface of the first wall 4a. Alternatively, the counter 38 may be configured so as to be rotated upward and have an adjustable angle so as to be aligned with the surface of the first wall 4a (i.e., a folded state). When configured so as to allow for vertical movement and angle adjustment, the multiple divided plate bodies 38b may be configured so as to be movable up and down and have an adjustable angle separately, or so as to be movable up and down and have an adjustable angle all at once.

[0195] In this embodiment, the counter 38 is composed of multiple divided plates 38b, and the gaps between these multiple divided plates 38b are designed to be passage sections 38a that allow lines of sight and air to pass through in the vertical direction, but this is not limited to this. That is, as shown in FIG. 18, a passing portion may be formed by processing one counter 39, 40, 41 provided so as to protrude from the wall surface of the first wall portion 4a.

[0196] A counter 39 shown in FIG. 18(a) has an arc-shaped cutout 39a formed therein, and the cutout 39a serves as a passage 39a through which lines of sight and air can pass in the vertical direction. The cutout 39a, which is the passage 39a, is formed in a semicircular shape at the center of the counter 39 in the width direction, so that the head of the user P positioned directly below the counter 39 is not completely covered by the counter 39.

[0197] The counter 40 shown in Figure 18(b) has multiple slits 40a formed along the length of the counter 40 and penetrating the board material of the counter 40 in the thickness direction, forming passages 40a that allow line of sight and air to pass through in the vertical direction. The multiple slits 40a that serve as passages 40a are spaced apart in the direction in which the counter 40 protrudes from the wall surface of the first wall portion 4a, so that the head of a user P positioned directly below is not completely covered by the counter 40.

[0198] The counter 41 shown in Figure 18(c) has multiple through holes 41a formed by penetrating the board material of the counter 41 in the thickness direction, which serve as passages 41a that allow lines of sight and air to pass through in the vertical direction. The plurality of through-holes 41a serving as passage sections 41a are arranged in a staggered pattern, so that the head of the user P positioned directly below the counter 41 is not completely covered by the counter 41.

[0199] Air (cool air) that has been temperature-adjusted above these counters 39, 40, 41 passes through passages 39a, 40a, 41a and circulates directly below the counters 39, 40, 41. In addition, the cool air that does not enter the passages 39a, 40a, 41a is blocked by the counters 39, 40, 41 and flows along the top surfaces of the counters 39, 40, 41 toward the toes. Meanwhile, air (warm air) that has been temperature-adjusted below the counters 39, 40, and 41 flows through the passages 39a, 40a, and 41a to the area directly above the counters 39, 40, and 41. The warm air that does not enter the passages 39a, 40a, and 41a is blocked by the counters 39, 40, and 41 and temporarily stagnates below the counters 39, 40, and 41, but then flows through the passages 39a, 40a, and 41a to the area directly above the counters 39, 40, and 41. This allows heat to escape from the space directly below the counters 39, 40, and 41, preventing heat from building up in the space.

[0200] Example 3-2 19, the room space 1 of this embodiment is provided with second air diffusion means 42, which is disposed on the side of the first wall portion 4a serving as a support, and which diffuses the indoor air whose temperature has been adjusted by radiant heat from the radiant heating and cooling device 12. The second air diffusion means 42 has a passage portion 42a which allows for line of sight and air to pass through in the vertical direction.

[0201] More specifically, the second air diffusion means 42 in this embodiment is a counter 42 that protrudes from the wall surface of the first wall portion 4a. The counter 42 is provided at a height position higher than the upper surface of the bed 10. The bed 10 is also installed so that one end 10a is located below the counter 42. In other words, the counter 42 is located above the head of the user P.

[0202] Counter 42 has a bulging portion 43 formed by bulging downward in the widthwise center of the rectangular plate material that makes up counter 42, and a cutout portion 43a is formed in the lowest part of this bulging portion 43. The bulging portion 43 is formed to gently slope downward from the upper surface of the plate material of the counter 42. The bulging portion 43 is formed in a U-shape in plan view. A cutout portion 43a is formed by cutting out a U-shape in a plan view in the bottom plate portion of the bulging portion 43. This cutout portion 43a serves as a passage portion 43a that allows for the passage of lines of sight and air in the vertical direction.

[0203] The counter 42 also includes side walls 44 that are integrally formed at both widthwise ends and fixed to the wall surfaces of the first wall 4a. These side walls 44 extend downward from both widthwise ends of the counter 42 and are formed so that their vertical dimensions gradually increase toward the wall surfaces of the first wall 4a. In other words, these side walls 44 function as brackets that support the counter 42 from below.

[0204] The radiant heating and cooling device 12 is incorporated and supported on the first wall portion 4a to which the counter 42 as described above is attached.

[0205] In the air conditioning system for the room space 1 of this embodiment, direct radiant heat from the radiant heating and cooling device 12 can heat or cool objects located nearby. Furthermore, the temperature of the air near the radiant heating and cooling device 12 is adjusted by radiant heat from the radiant heating and cooling device 12. Cooled air has a tendency to descend. The air (cold air) whose temperature has been adjusted at a position above the counter 42 flows directly below the counter 42 through a passage 43a formed by a notch at the lower end of the bulging portion 43. The upper surface of the bulging portion 43 is gently inclined. Therefore, the air that gathers in the center of the width of the counter 42 easily flows along the upper surface of the bulging portion 43 into the space below. Furthermore, the cold air that does not enter the passage 43a is blocked by the counter 42 and flows along the upper surface of the counter 42 toward the toes. On the other hand, heated air has the tendency to rise. Air (warm air) that has been temperature-adjusted below the counter 42 flows directly above the counter 42 through a passage 43a formed by a notch at the bottom end of the bulging portion 43. Warm air that does not enter the passage 43a is blocked by the counter 42 and the side walls 44 on both sides, and tends to stagnate on the underside of the counter 42. As a result, for those who want to prevent warm air from escaping all at once through the passage 43a, the counter 42 can minimize the escape of the rising warm air.

[0206] The air conditioning system for the room space 1 of this embodiment as described above can not only air condition the entire room space 1, but also contribute to creating a good sleeping environment in the bed 10, which is positioned with one end 10a close to the first wall portion 4a. In particular, the counter 42 has a notch 43a formed at the lower end of the bulging portion 43, which serves as a passage 43a that allows line of sight and air to pass through in the vertical direction, so that a user P with their head positioned below it feels less oppressive than if line of sight and air were not able to pass through. In addition, the plate material and bulging portion 43 that make up the counter 42 can effectively diffuse cool air that has been temperature-adjusted above the counter 42 and warm air that has been temperature-adjusted below the counter 42.

[0207] Although the counter 42 in this embodiment is configured so as not to move up and down or adjust its angle, this is not limiting and the counter 42 may be provided so as to be movable up and down along the wall surface of the first wall 4a, or so as to be able to adjust its angle relative to the wall surface of the first wall 4a. Alternatively, the counter 42 may be configured so as to be rotated upward and be able to adjust its angle so as to be in a state where it is in a folded state along the wall surface of the first wall 4a.

[0208] Example 3-3 20, the room space 1 of this embodiment is provided with third air diffusion means 45, which is disposed on the side of the first wall portion 4a serving as a support body and which diffuses the indoor air whose temperature has been adjusted by radiant heat from the radiant heating and cooling device 12. The third air diffusion means 45 has passage portions 45a which allow lines of sight and air to pass through in the vertical direction.

[0209] More specifically, the third air diffusion means 45 in this embodiment is a counter 45 that protrudes from the wall surface of the first wall portion 4a. The counter 45 is provided at a height position higher than the upper surface of the bed 10. The bed 10 is also installed so that one end 10a is located below the counter 45. In other words, the counter 45 is located above the head of the user P.

[0210] 20(a) and 20(b), the counter 45 is made up of a plurality of divided plates 45b spaced apart in the width direction on the wall surface of the first wall 4a. In this embodiment, two divided plates 45b are spaced apart in the width direction on the wall surface of the first wall 4a, and a gap 45a between these two divided plates 45b serves as a passage 45a through which lines of sight and air can pass in the vertical direction. The divided plate bodies 45b are made of rectangular plate material, and the dimension from the outer surface of one divided plate body 45b to the outer surface of the other divided plate body 45b is set to be approximately equal to the width dimension of the bed 10.

[0211] In the example shown in FIG. 20(a), a passage portion 45a, which is a gap between two divided plates 45b, can be opened and closed by two opening and closing bodies . Each opening / closing body 46 is attached to the lower surface of the corresponding divided plate body 45b via a movable mechanism 46a such as a slide rail. Furthermore, each opening / closing body 46 is located lower than the lower surface of the corresponding divided plate body 45b. The distance between the two divided plates 45b is set shorter than the distance when the two opening / closing bodies 46 are arranged side by side, so that the two opening / closing bodies 46 can reliably block the passage portion 45a, which is the gap between the two divided plates 45b.

[0212] In the example shown in FIG. 20(b), the passage portion 45a, which is the gap between the two divided plate members 45b, can also be opened and closed by the two opening / closing members . Each opening / closing body 46 is attached to the ceiling of a recess 45c formed in the lower surface of the corresponding divided plate 45b via a movable mechanism 46a such as a slide rail. Furthermore, each opening / closing body 46 is located above the lower surface of the corresponding divided plate 45b. The distance between the two divided plates 45b is set shorter than the distance when the two opening / closing bodies 46 are arranged side by side, so that the two opening / closing bodies 46 can reliably block the passage portion 45a, which is the gap between the two divided plates 45b.

[0213] In this embodiment, the opening / closing body 46 is configured to open and close the passage section 45a by opening and closing it in the width direction of the counter 45 using a movable mechanism 46a, such as a long slide rail, along the length of the counter 45, but this is not limited to this. In other words, the opening and closing operation of the opening and closing body 46 is not limited to that by the long slide rail 46a, but the opening and closing body 46 and the dividing plate body 45b may be rotatably connected via a hinge (i.e., a movable mechanism), and the opening and closing body 46 may be rotated in the vertical direction to open and close the passage section 45a. In addition, one corner of the opening / closing body 46 and one corner of the dividing plate body 45b may be connected via a rotating shaft (i.e., a movable mechanism) so as to be capable of horizontal rotation, and the opening / closing body 46 may be rotated horizontally to open and close the passage section 45a. Furthermore, although the opening / closing body 46 in this embodiment is positioned below the divided plate body 45b, this is not limitative and the opening / closing body 46 may be positioned above the divided plate body 45b. In other words, the opening / closing body 46 may be turned upside down from the state shown in Figures 20(a) and (b).

[0214] The radiant heating and cooling device 12 is incorporated and supported on the first wall portion 4a to which the counter 45 as described above is attached.

[0215] In the air conditioning system for the room space 1 of this embodiment, direct radiant heat from the radiant heating and cooling device 12 can heat or cool objects located nearby. Furthermore, the temperature of the air near the radiant heating and cooling device 12 is adjusted by radiant heat from the radiant heating and cooling device 12. Of the air whose temperature has been adjusted by the radiant heating and cooling device 12, the air whose temperature has been adjusted at a position above the counter 45, which serves as the third air diffusion means, is less likely to circulate directly below the counter 45 when the opening / closing body 46 is blocking the passage 45a. Furthermore, the air whose temperature has been adjusted at a position below the counter 45, which serves as the third air diffusion means, is less likely to circulate directly above the counter 45 when the opening / closing body 46 is blocking the passage 45a.

[0216] More specifically, cooled air has a tendency to descend. When passage 45a is closed by opening / closing body 46, the air (cold air) that has been temperature-adjusted above counter 45 is less likely to circulate directly below counter 45. Therefore, for people who dislike cold air hitting their face, closing passage 45a with opening / closing body 46 can block the descending cold air as much as possible. The cool air blocked by the counter 45 flows downward from the end of the counter 45 on the protruding direction side (and the end on the foot side of the user P), and therefore is more likely to flow toward the foot side of the user P than toward the head side. If the person does not mind having cold air blown on their face, the opening and closing body 46 is opened to open the passage portion 45a, and the descending cold air is allowed to circulate below the counter 45.

[0217] On the other hand, heated air has the tendency to rise. Air that has been temperature-adjusted below the counter 45 is less likely to circulate directly above the counter 45, so for those who want to prevent warm air from escaping, closing the passage 45a with the opening / closing body 46 can minimize the escape of the rising warm air. If a person wants to prevent warm air from building up, the opening and closing body 46 is opened to open the passage portion 45 a, and the rising warm air is allowed to circulate above the counter 45 .

[0218] In other words, the counter 45, which is the third air diffusion means, can control the air flow in multiple patterns by appropriately opening and closing the opening / closing body 46, so it also functions as an air flow control means. Therefore, the air conditioning system for the room space 1 of this embodiment as described above can not only air condition the entire room space 1, but also contribute to creating a good sleeping environment in the bed 10, one end 10a of which is positioned close to the first wall portion 4a.

[0219] Furthermore, the counter 45 is configured so that the opening / closing body 46 can be opened and closed, so that by opening the opening / closing body 46 and opening the passage section 45a, the first wall section 4a (or the raised wall 5) can be used as a headboard for the bed 10, and the user P can use it as a backrest.

[0220] [Example 3-4] 21, the room space 1 of this embodiment is provided with fourth air diffusion means 47, which is disposed on the side of the first wall portion 4a serving as a support body and which diffuses the indoor air whose temperature has been adjusted by radiant heat from the radiant heating and cooling device 12. The fourth air diffusion means 47 has passage portions 47a which allow lines of sight and air to pass through in the vertical direction.

[0221] More specifically, the fourth air diffusion means 47 in this embodiment is a counter 47 that protrudes from the wall surface of the first wall portion 4a. The counter 47 is provided at a height position higher than the upper surface of the bed 10. The bed 10 is also installed so that one end 10a is located below the counter 47. In other words, the counter 47 is located above the head of the user P.

[0222] As shown in Figure 21, the counter 47 has a rectangular opening 47a formed in the center of the rectangular plate material that makes up the counter 47, penetrating the plate material in the thickness direction, and this opening 47a serves as a passage 47a that allows lines of sight and air to pass through in the vertical direction. The width of the counter 47 is set to be approximately equal to the width of the bed 10.

[0223] A passage 47a, which is an opening formed in the center of the counter 47, is provided with a louver device 48 as an opening / closing body for opening and closing the passage 47a. The louver device 48 has a frame body fixed to the peripheral edge of the passage portion 47a, which is an opening, and a plurality of fins 48a formed long along the width direction of the counter 47 and held by the frame body. The multiple fins 48a have a rotation axis running along the length direction, and are attached to the frame in a state where they can rotate around the rotation axis. In the example shown in Fig. 21, by rotating the multiple fins 48a in a lying position in the same direction and bringing the fins 48a into contact with each other, it is possible to close the passage portion 47a, which is an opening. Furthermore, by rotating the multiple fins 48a in the same direction and moving the fins 48a away from each other, it is possible to open the passage portion 47a, which is an opening.

[0224] The radiant heating and cooling device 12 is incorporated and supported on the first wall portion 4a to which the counter 47 as described above is attached.

[0225] In the air conditioning system for the room space 1 of this embodiment, direct radiant heat from the radiant heating and cooling device 12 can heat or cool objects located nearby. Furthermore, the temperature of the air near the radiant heating and cooling device 12 is adjusted by radiant heat from the radiant heating and cooling device 12. Of the air whose temperature has been adjusted by the radiant heating and cooling device 12, the air whose temperature has been adjusted at a position above the counter 47, which serves as the fourth air diffusion means, is less likely to circulate directly below the counter 47 when the passing section 47a is blocked by the multiple fins 48a. Furthermore, the air whose temperature has been adjusted at a position below the counter 47, which serves as the fourth air diffusion means, is less likely to circulate directly above the counter 47 when the passing section 47a is blocked by the multiple fins 48a.

[0226] More specifically, cooled air has a tendency to descend. When passage 47a is blocked by fins 48a, the air (cold air) that has been temperature-adjusted above counter 47 is less likely to circulate directly below counter 47. Therefore, for people who dislike cold air hitting their face, blocking passage 47a with fins 48a can block the descending cold air as much as possible. The cool air blocked by the counter 47 flows downward from the end of the counter 47 on the protruding direction side (and the end on the foot side of the user P), and therefore is more likely to flow toward the foot side of the user P than toward the head side. For those who do not mind having cold air blown on their faces, the fins 48a are rotated to open the passage 47a, allowing the descending cold air to flow below the counter 47.

[0227] On the other hand, heated air has the tendency to rise. Air that has been temperature-adjusted below the counter 47 is less likely to circulate directly above the counter 47, so for those who want to prevent warm air from escaping, closing the passage 47a with multiple fins 48a can minimize the escape of the rising warm air. For those who want to prevent warm air from building up, the fins 48 a are rotated to open the passage 47 a, allowing the rising warm air to flow above the counter 47 .

[0228] In other words, the counter 47, which is the third air diffusion means, can control the air flow in multiple patterns by appropriately opening and closing the multiple fins 48a of the opening and closing body 48, so it also functions as an airflow control means. Therefore, the air conditioning system for the room space 1 of this embodiment as described above can not only air condition the entire room space 1, but also contribute to creating a good sleeping environment in the bed 10, one end 10a of which is positioned close to the first wall portion 4a. The angle adjustment of the plurality of fins 48a is performed automatically or manually. When the operation is performed automatically, the louver device 48, which is the opening and closing body, is provided with a drive unit for rotating the multiple fins 48a. This drive unit can be controlled in a similar configuration to the above-mentioned automatic control system (see FIG. 6). That is, the drive unit is connected by wire or wirelessly to a control device configured by a computer, and is controlled by the control device according to a program stored in a memory unit. The control device is also configured to control the drive unit according to the sensing results of a status detection sensor 21 installed in the room space 1.

[0229] According to this embodiment, the following excellent effects are achieved. That is, counters 38, 39, 40, 41, 42, 45, 47 protruding forward from the surface of wall portion 4 have passages 38a, 39a, 40a, 41a, 43a, 45a, 47a that allow at least line of sight and air to pass through in the vertical direction of counters 38, 39, 40, 41, 42, 45, 47, so that line of sight can pass through in the vertical direction and air can also pass through in the vertical direction through passages 38a, 39a, 40a, 41a, 43a, 45a, 47a. This makes it less likely that user P will feel a sense of oppression, and a sleeping environment with as little oppressive feeling as possible can be created. Furthermore, since the radiant heating and cooling device 12 is incorporated into and supported on the wall portion 4 to which the counters 38, 39, 40, 41, 42, 45, 47 are attached, objects located nearby can be heated or cooled by direct radiant heat from the radiant heating and cooling device 12, and air (cold air) whose temperature has been adjusted by the radiant heating and cooling device 12 at a position above the counters 38, 39, 40, 41, 42, 45, 47 can be made to descend into the space below through the passages 38a, 39a, 40a, 41a, 43a, 45a, 47a, or can be made to descend along the top surfaces of the counters 38, 39, 40, 41, 42, 45, 47 from the end portion on the protruding direction side. In addition, the air (warm air) whose temperature has been adjusted by the radiant heating and cooling device 12 at a position below the counters 38, 39, 40, 41, 42, 45, and 47 can be released upward through the passages 38a, 39a, 40a, 41a, 43a, 45a, and 47a, preventing heat from building up. This makes it possible to create a comfortable thermal environment in the room space 1 by utilizing the air whose temperature has been adjusted by the radiant heating and cooling device 12.

[0230] Furthermore, the gaps between the multiple divided plates 38b, 45b arranged at intervals in the width direction on the wall surface of the wall portion 4 serve as passages 38a, 45a, which allow for clear lines of sight in the vertical direction and also allow air to pass through in the vertical direction. This makes it difficult for the user P to feel a sense of oppression, thereby creating a sleeping environment that minimizes the feeling of oppression. Furthermore, because the radiant heating and cooling device 12 is built into and supported on the wall portion 4 to which the counters 38, 45 are attached, it is possible to heat or cool objects located nearby using direct radiant heat from the radiant heating and cooling device 12, and it is also possible to effectively diffuse temperature-adjusted cold air above the counters 38, 45 and temperature-adjusted warm air below the counters 38, 45. This makes it possible to create a comfortable thermal environment in the room space 1 by using the air temperature-adjusted by the radiant heating and cooling device 12.

[0231] Moreover, the counter 45 further includes an opening / closing body 46 that opens and closes the passage portion 45a, so that the passage portion 45a can be blocked by the opening / closing body 46 to prevent the line of sight from slipping out. Furthermore, by appropriately opening and closing the passage section 45a using the opening and closing body 46, it is possible to control the flow of temperature-adjusted cold air above the counter 45 and the flow of temperature-adjusted warm air below the counter 45 in multiple patterns.

[0232] Furthermore, since the passage sections 39a, 43a are notches 39a, 43a formed in the edge portions of the counters 39, 42, users P using the space below the counters 39, 42 are less likely to feel a sense of oppression compared to when there is no line of sight or air passage. Furthermore, when creating a comfortable thermal environment in the room space 1 by using temperature-adjusted cold air at a position above the counters 39, 42 or temperature-adjusted warm air at a position below the counters 39, 42, it is possible to create an air flow that is different from that when, for example, an opening formed in the counter is used as a passage or when a gap between spaced-apart boards is used as a passage.

[0233] In addition, a notch 43a is formed in the lowest position of the bulge 43 formed in the widthwise center of the board material that makes up the counter 42, so that the air (cold air) that gathers in the widthwise center of the counter 42 can easily flow along the top surface of the bulge 43 into the space below, making it easier for it to descend through the notch 43a.

[0234] Furthermore, since the passage sections 40a, 41a, 47a are openings 40a, 41a, 47a that penetrate the counters 40, 41, 47 in the thickness direction, users P who use the space below the counters 40, 41, 47 are less likely to feel oppressive than if their line of sight and air could not pass through. Furthermore, when creating a comfortable thermal environment in the room space 1 by using temperature-adjusted cold air at a position above the counters 40, 41, 47 or temperature-adjusted warm air at a position below the counters 40, 41, 47, it is possible to create an air flow that is different from the case where a notch formed in the edge of the counter is used as the passage part or the gap between spaced-apart boards is used as the passage part.

[0235] In addition, the opening / closing body 48 that opens and closes the passage section 47a is a louver device 48 that is provided in the passage section 47a and has multiple fins 48a arranged in parallel that can rotate around the axis of a rotation shaft, so that the passage section 45a can be blocked by the multiple fins 48a to prevent the view from slipping through. Furthermore, by appropriately opening and closing the passage 45a using the multiple fins 48a, it is possible to control the flow of temperature-adjusted cold air above the counter 47 and the flow of temperature-adjusted warm air below the counter 47 in multiple patterns.

[0236] <Fourth embodiment> Next, a fourth embodiment will be described with reference to the drawings. For ease of explanation, elements common to the first to third embodiments will be denoted by the same reference numerals, and explanations thereof will be omitted or simplified.

[0237] The room space 1 in this embodiment is an internal space of a room in which bedding 10 is installed, such as a master bedroom (bedroom), a child's room, or a guest room in a house. The room space 1 is surrounded by a floor 2, a ceiling 3, and a plurality of walls 4. The room space 1 is equipped with bedding 10 and a radiant heating and cooling device 12. An air conditioning system including a radiant heating and cooling device 12 is installed in the room space 1 configured as above.

[0238] [Example] The air conditioning system for the room space 1 in this embodiment will be described in more detail below. It should be noted that each embodiment of the air conditioning system described below is premised on having the above-described configuration of the room space 1. Common elements are given common reference numerals, and descriptions thereof will be omitted or simplified as appropriate.

[0239] Example 4-1 22(a) and 22(b), the room space 1 of this embodiment is provided with a counter 49, which is disposed on the side of the first wall portion 4a, which is the support body, and which serves as a fifth air diffusion means 49 that diffuses the indoor air whose temperature has been adjusted by radiant heat from the radiant heating and cooling device 12. Furthermore, illuminance increasing means 50 and 51 that increase the illuminance in the space below the counter 49 are provided on the underside of the counter 49.

[0240] More specifically, the counter 49, which is the fifth air diffusion means 49 of this embodiment, is provided to protrude from the wall surface of the first wall portion 4a. The counter 49 is provided at a height position higher than the upper surface of the bed 10. The bed 10 is also installed so that one end portion 10a is located below the counter 49. In other words, the counter 49 is located above the head of the user P.

[0241] The counter 49 is made of a rectangular plate material, and its width is set to be approximately equal to the width of the bed 10. Illumination devices 50 and 51 are provided as illumination increasing means on the underside of the counter 49. The illumination devices 50 and 51 are, for example, LED illumination devices, and are connected to a power supply unit (not shown) to receive power supply.

[0242] Furthermore, the lighting devices 50 and 51 are configured so that not only can they be turned on and off but also the illuminance can be adjusted by operating a controller (not shown). Furthermore, the controller is provided with a timer function, which allows the on / off of the lighting device 36 and adjustment of the brightness to be controlled by a timer. The controller can be replaced by a computer such as a smartphone with a dedicated application downloaded onto it.

[0243] In the example shown in FIG. 22(a), the lighting device 50 is of a direct lighting type and is exposed on the underside of the counter 49. 22(b), lighting device 51 is of an indirect lighting type and is not exposed from the underside of counter 49. That is, lighting storage section 52, which is formed in a substantially J-shape in a side cross-sectional view, is provided at the end of counter 49 in the protruding direction, and lighting device 51 is stored in lighting storage section 52 so that light from lighting device 51 does not directly enter the eyes of user P standing below counter 49. The lighting storage section 52 has a first plate 52a extending downward from the end of the counter 49 in the protruding direction, a second plate 52b extending from the lower end of the first plate 52a toward the first wall 4a and having the lighting device 51 mounted on its upper surface, and a third plate 52c extending upward from the end of the second plate 52b on the first wall 4a side. A gap is formed between the upper end of the third plate 52c and the underside of the counter 49, allowing light from the lighting device 51 to leak through this gap. The second plate 52b functions as a shield to prevent light from directly reaching a user P using the space below.

[0244] The radiant heating and cooling device 12 is incorporated and supported on the first wall portion 4a to which the counter 49 as described above is attached.

[0245] In the air conditioning system for the room space 1 of this embodiment, direct radiant heat from the radiant heating and cooling device 12 can heat or cool objects located nearby. Furthermore, the temperature of the air near the radiant heating and cooling device 12 is adjusted by radiant heat from the radiant heating and cooling device 12. Of the air whose temperature has been adjusted by the radiant heating and cooling device 12, the air whose temperature has been adjusted at a position above the counter 49, which is the fifth air diffusion means, is less likely to circulate directly below the counter 49. Furthermore, the air whose temperature has been adjusted at a position below the counter 49 is less likely to circulate directly above the counter 49.

[0246] To explain in more detail, cooled air has the tendency to descend. Air that has been temperature-adjusted above the counter 49 is less likely to circulate directly below the counter 49, so for people who dislike cold air hitting their face, the counter 49 can block the descending cold air as much as possible. The cool air blocked by the counter 49 flows downward from the protruding side end (and widthwise side end) of the counter 49, and therefore is more likely to flow toward the feet of the user P than toward the head.

[0247] On the other hand, heated air has the tendency to rise. Air that has been temperature-adjusted below the counter 49 is less likely to circulate directly above the counter 49, so for those who want to prevent warm air from escaping, the counter 49 can minimize the escape of rising warm air. In particular, if a hanging lighting storage section 52 is provided at the end of the counter 49 in the protruding direction, the warm air that has been temperature-adjusted below the counter 49 tends to remain on the underside of the counter 49, thereby minimizing the escape of the rising warm air.

[0248] The air conditioning system for the room space 1 of this embodiment as described above can not only air condition the entire room space 1, but also contribute to creating a good sleeping environment in the bed 10, which is positioned with one end 10a close to the first wall portion 4a. Furthermore, lighting devices 50, 51 are provided on the underside of counter 49, making it possible to adjust the illuminance in the space below counter 49. This allows the space below counter 49 to be brightened even if it becomes a low-illuminance space due to the shadow of counter 49, thereby contributing to the creation of a good wake-up environment.

[0249] Although the counter 49 in this embodiment is configured so as not to move up and down or adjust its angle, the present invention is not limited to this and may be provided so as to be movable up and down along the wall surface of the first wall 4a, or so as to be able to adjust its angle relative to the wall surface of the first wall 4a. Alternatively, the counter 49 may be configured so as to be rotated upward and be able to adjust its angle so as to be in a state where it is in a folded state along the wall surface of the first wall 4a.

[0250] Example 4-2 23, the room space 1 of this embodiment is provided with a counter 53, which is disposed on the side of the first wall portion 4a, which is the support body, and which serves as a sixth air diffusion means 53 that diffuses the indoor air whose temperature has been adjusted by radiant heat from the radiant heating and cooling device 12. An illuminance increasing means 54 that increases the illuminance in the space below the counter 53 is provided on the underside of the counter 53.

[0251] More specifically, the counter 53, which is the sixth air diffusion means 53 of this embodiment, is provided to protrude from the wall surface of the first wall portion 4a. The counter 53 is provided at a height position higher than the upper surface of the bed 10. The bed 10 is also installed so that one end 10a is located below the counter 53. In other words, the counter 53 is located above the head of the user P.

[0252] The counter 53 is made of a rectangular plate material, and its width is set to be approximately equal to the width of the bed 10. A monitor 54 is provided on the underside of the counter 53 as a means for increasing illumination. The monitor 54 refers to a device that displays characters, figures, graphics, videos, etc., and is also called a display or display device. Note that a tablet terminal or television equipped with a display unit with similar functions may also be used instead. Such a monitor 54 is connected to a power supply unit (not shown) to receive power. The monitor 54 can be turned on and off by operating a controller (not shown), and the brightness of the screen can be adjusted. The monitor 54 may also be equipped with a speaker and a microphone.

[0253] The monitor 54 may be used not only to adjust the brightness but also to alleviate the sense of oppression caused by the counter 53 being above the user's head by displaying an image or the like on the screen. For example, by displaying the night sky on the screen of the monitor 54 when the user goes to sleep, or a blue sky on the screen of the monitor 54 when the user wakes up, the user P can be given a sense of freedom of sight, thereby alleviating the sense of oppression. In addition, an image of a natural environment such as a forest may be displayed on the screen. Furthermore, a camera may be installed on the counter 53 to display the ceiling 3, or a camera may be installed on the roof and the view captured by the camera may be displayed on the monitor 54.

[0254] A recess 53a is formed on the underside of the counter 53, and a monitor 54 is housed in this recess 53a. When a tablet terminal is used as the monitor 54, for example, the monitor 54 stored in the recess 53a may be held in place by a fastener such as a register mark, so that the monitor 54 can be easily stored in and removed from the recess 53a.

[0255] The radiant heating and cooling device 12 is incorporated and supported on the first wall portion 4a to which the counter 49 as described above is attached.

[0256] In the air conditioning system for the room space 1 of this embodiment, direct radiant heat from the radiant heating and cooling device 12 can heat or cool objects located nearby. Furthermore, the temperature of the air near the radiant heating and cooling device 12 is adjusted by radiant heat from the radiant heating and cooling device 12. Of the air whose temperature is adjusted by the radiant heating and cooling device 12, the air whose temperature is adjusted at a position above the counter 53, which is the sixth air diffusion means, is less likely to circulate directly below the counter 53. Furthermore, the air whose temperature is adjusted at a position below the counter 53 is less likely to circulate directly above the counter 53.

[0257] To explain in more detail, cooled air has the tendency to descend. Air that has been temperature-adjusted above the counter 53 is less likely to circulate directly below the counter 53, so for people who dislike cold air hitting their face, the counter 53 can block the descending cold air as much as possible. The cool air blocked by the counter 53 flows downward from the protruding side end (and widthwise side end) of the counter 53, and therefore is more likely to flow toward the feet of the user P than toward the head.

[0258] On the other hand, heated air has the tendency to rise. Air that has been temperature-adjusted below the counter 53 is less likely to circulate directly above the counter 53, so for those who want to prevent warm air from escaping, the counter 53 can minimize the escape of rising warm air. The warm air, whose temperature has been adjusted at a position below the counter 53, gradually rises and diffuses from the end of the counter 53 on the protruding side.

[0259] The air conditioning system for the room space 1 of this embodiment as described above can not only air condition the entire room space 1, but also contribute to creating a good sleeping environment in the bed 10, which is positioned with one end 10a close to the first wall portion 4a. Furthermore, by providing a monitor 54 on the underside of the counter 53, it is possible to adjust the illuminance in the space below the counter 53. This allows the space below the counter 53 to be brightened even if it becomes a low-illuminance space due to being shaded by the counter 53, thereby contributing to the creation of a good wake-up environment.

[0260] Although the counter 53 in this embodiment is configured so as not to move up and down or adjust its angle, the present invention is not limited to this and may be provided so as to be movable up and down along the wall surface of the first wall 4a, or so as to be able to adjust its angle relative to the wall surface of the first wall 4a. Alternatively, the counter 53 may be configured so as to be rotated upward and be able to adjust its angle so as to be in a state where it is in a folded state along the wall surface of the first wall 4a.

[0261] Example 4-3 24, the room space 1 of this embodiment is provided with a counter 55, which is disposed on the side of the first wall portion 4a, which is the support body, and which serves as seventh air diffusion means 55 that diffuses the indoor air whose temperature has been adjusted by radiant heat from the radiant heating and cooling device 12. Further, an illuminance increasing means 56 that increases the illuminance in the space below the counter 55 is provided on the underside of the counter 55.

[0262] More specifically, the counter 55, which is the seventh air diffusion means 55 of this embodiment, is provided to protrude from the wall surface of the first wall portion 4a. The counter 55 is provided at a height position higher than the upper surface of the bed 10. The bed 10 is also installed so that one end 10a is located below the counter 55. In other words, the counter 55 is located above the head of the user P.

[0263] The counter 55 is made of a rectangular plate material, and its width is set to be approximately equal to the width of the bed 10. A mirror 56 is provided on the underside of such counter 55 as an illumination increasing means, with the mirror surface facing downward and tilted at an angle. Therefore, when user P lies down on bed 10 with his / her head placed below mirror 56, light taken in from outside the space below counter 55 reaches his / her eyes. In other words, if room space 1 is darkened while sleeping, it is difficult for light to reach user P's eyes, but in the morning, natural light entering room space 1 from outside can easily reach user P's eyes. In addition, user P can see his / her feet through mirror 56 without having to raise his / her head.

[0264] The mirror 56 is a normal mirror, and is provided so as to bridge between the lower surface portion of the end portion of the counter 55 in the protruding direction and the first wall portion 4a. An insertion groove 55a is formed on the underside of the counter 55 at the end of the protruding direction, extending along the width of the counter 55, and the upper end of the mirror 56 is inserted into this insertion groove 55a. A mirror receiving portion 57 that receives the lower end of the mirror 56 is attached to the wall surface of the first wall portion 4a. The end surface of the mirror receiving portion 57 facing in the protruding direction is an obliquely upward surface, and an insertion groove 57a is formed in the end surface in the protruding direction. The upper end of the mirror 56 is inserted into this insertion groove 57a.

[0265] The radiant heating and cooling device 12 is incorporated and supported on the first wall portion 4a to which the counter 55 as described above is attached.

[0266] In the air conditioning system for the room space 1 of this embodiment, direct radiant heat from the radiant heating and cooling device 12 can heat or cool objects located nearby. Furthermore, the temperature of the air near the radiant heating and cooling device 12 is adjusted by radiant heat from the radiant heating and cooling device 12. Of the air whose temperature has been adjusted by the radiant heating and cooling device 12, the air whose temperature has been adjusted at a position above the counter 55, which is the seventh air diffusion means, is less likely to circulate directly below the counter 55. Furthermore, the air whose temperature has been adjusted at a position below the counter 55 is less likely to circulate directly above the counter 55.

[0267] To explain in more detail, cooled air has a tendency to descend. Air that has been temperature-adjusted above the counter 55 is less likely to circulate directly below the counter 55, so for people who dislike cold air hitting their face, the counter 55 can block the descending cold air as much as possible. The cool air blocked by the counter 55 flows downward from the protruding side end (and widthwise side end) of the counter 55, and therefore is more likely to flow toward the feet of the user P than toward the head.

[0268] On the other hand, heated air has a tendency to rise. Air that has been temperature-adjusted below the counter 55 and above the mirror 56 is less likely to circulate directly above the counter 55, so for those who want to prevent warm air from escaping, the counter 55 can effectively prevent the rising warm air from escaping. Closing the open areas at both widthwise ends of the counter 55 and mirror 56 makes it even more difficult for warm air to escape. The warm air, whose temperature has been adjusted at a position below the mirror 56, rises along the mirror 56 and gradually rises from the end of the counter 55 in the protruding direction and diffuses.

[0269] The air conditioning system for the room space 1 of this embodiment as described above can not only air condition the entire room space 1, but also contribute to creating a good sleeping environment in the bed 10, which is positioned with one end 10a close to the first wall portion 4a. Furthermore, by providing a mirror 56 on the underside of the counter 55, it is possible to adjust the illuminance in the space below the counter 55. This allows the space below the counter 55 to be brightened even if it becomes a low-illuminance space due to the shadow of the counter 55, thereby contributing to the creation of a good environment for waking up.

[0270] According to this embodiment, the following excellent effects are achieved. That is, because the radiant heating and cooling device 12 is incorporated into and supported on the wall portion 4 to which the counters 49, 53, and 55 are attached, not only can objects located nearby be heated or cooled by direct radiant heat from the radiant heating and cooling device 12, but also air (cold air) temperature-adjusted by the radiant heating and cooling device 12 at a position above the counters 49, 53, and 55 can be made to flow down from the protruding side end along the top surface of the counters 49, 53, and 55, and air (warm air) temperature-adjusted by the radiant heating and cooling device 12 at a position below the counters 49, 53, and 55 can be made to stagnate on the underside of the counters 49, 53, and 55 to prevent the air from escaping. This makes it possible to create a comfortable thermal environment in the room space 1 by using the air temperature-adjusted by the radiant heating and cooling device 12. Furthermore, the counters 49, 53, 55 are provided with illuminance increasing means 50, 51, 54, 56 that increase the illuminance in the space below the counters 49, 53, 55, so even if the space below the counters 49, 53, 55 is shaded by the counters 49, 53, 55 and becomes a low-illuminance space, the illuminance increasing means 50, 51, 54, 56 can brighten the space below the counters 49, 53, 55. This makes it possible to create a sleeping environment (waking-up environment) that makes it easier to wake up in terms of illuminance.

[0271] Furthermore, since the illumination increasing means 50, 51 are lighting devices 50, 51 provided on the underside of the counter 49, they are dedicated devices with the function of brightening the illuminated area and can directly brighten the space below the counters 49, 53, 55. This makes it easier to create a sleeping environment that makes it easier to wake up in terms of illumination.

[0272] Counter 49 also has lighting storage section 52 for storing lighting device 51 and for positioning lighting device 51 below the underside of counter 49, and a gap is formed between the underside of counter 49 and lighting storage section 52, so that light leaking through the gap can brighten the space below counters 49, 53, and 55. In other words, lighting device 51 stored in lighting storage section 52 can function as indirect lighting, so that the space below counter 49 can be illuminated with soft light reflected off the underside of counter 49, etc., unlike when illuminated by light that directly hits the eyes.

[0273] Furthermore, the illuminance increasing means 54 is a monitor 54 that is provided on the underside of the counter 53 and displays images, so it can brighten the space below the counter 53 while displaying images. This makes it easier to create a sleeping environment that makes it easier to wake up in terms of illuminance. Furthermore, depending on the image displayed, it is possible to alleviate the sense of oppression caused by the presence of counter 53 for users P who use the space below counter 53.

[0274] Furthermore, mirror 56 is provided at an angle on the underside of counter 55, and is positioned so that the mirror surface faces diagonally downward on the opposite side from wall 4, so that light taken in from outside the space below counter 55 reaches user P who uses the space below counter 55. As a result, if room space 1 is darkened at bedtime, light is less likely to reach user P who uses the space below counter 55, but in the morning, natural light that enters room space 1 from outside can more easily reach user P who uses the space below counter 55, so it becomes easier to create a sleeping environment that makes it easier to wake up in terms of illuminance. Furthermore, a user P using the space below the counter 55 can see the outside of the space below the counter 55 through the mirror 56, which helps to eliminate the feeling of oppression caused by the presence of the counter 55 for the user P using the space below the counter 55.
