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 an air conditioning system that provides a comfortable thermal environment (sleeping environment) for the bed occupant by attaching a radiant panel that performs radiant heating and cooling by thermal radiation to a support such as a headboard located at the head side of the bed or a wall. In Patent Document 1, the lower end of the radiant panel is provided with an inclined portion (reverse plate) that gradually slopes downward as it approaches the bed. The surrounding air is heat exchanged with the radiant heat from the radiant panel, becoming cooled air (hereinafter, "cold air"), and the cold air flows along the inclined portion due to natural convection in the room. This makes it possible to efficiently provide a feeling of coolness 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] However, in the conventional technology, although it is possible to make the cold air flow along the inclined portion and beyond the inclined portion, the inclined portion is simply provided at the lower end of the radiant panel, so it is always constant and it is not possible to control the airflow caused by convection in the room. As a result, the cold air continues to hit the head of the bed user, which may actually reduce the comfort of the bed user.

[0005] The present invention has been made in consideration of the above circumstances, and an object of the present invention is to create a comfortable thermal environment in a room space by utilizing air whose temperature has been adjusted by a radiant heating and cooling device.

[0028] Hereinafter, the 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. The embodiments described below may be combined as much as possible.

[0029] First Embodiment In Fig. 1, reference numeral 1 denotes a room space. This room space 1 is an internal space of a room in which bedding 10 is installed, such as a master bedroom, a child's room, or a guest room in a house. The room space 1 is surrounded and formed by a floor 2, a ceiling 3, and a number of walls 4.

[0030] 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 over the entire surface, but may have stepped portions such as a skip floor, a raised platform, or a sunken kotatsu. In addition, a carpet such as a tile carpet may be laid on the upper surface of the floor part 2 to prevent the floor part 2 from being scratched by the legs of the bedding 10.

[0031] The ceiling section 3 is located above the floor section 2 and is configured so that the ceiling height is the same as that of other rooms in the house, such as living spaces, although this is not the case in the case of an open-ceilinged room or a low-ceilinged room such as a loft. The ceiling portion 3 in this embodiment is set to the same height over the entire surface, but may be a sloped ceiling or a raised ceiling.

[0032] The walls 4 are disposed between the floor 2 and the ceiling 3, and separate the room space 1 from other rooms or the outdoors. The walls 4 may be provided continuous with walls that form other rooms in the house. The 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 multiple wall portions 4 has an opening (not shown) for entering and exiting the room space 1. The multiple wall portions 4 may also have an opening (not shown) that communicates with the outdoors.

[0033] The room space 1 is equipped with bedding 10 and a radiant heating and cooling device 12.

[0034] 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 provided on a platform body, and hereinafter, the top surface of the bed refers to the top surface of the mattress. The thickness of the mattress can be changed as appropriate. Pillows, comforters, and the like are also used as appropriate in combination with the bed 10.

[0035] The bed 10 is installed in the room space 1 with one end 10a, where the head of the user P is located, facing one of the multiple walls 4. In other words, the first wall 4a can be used in place of a headboard. The portion of the wall surface of the first wall 4a to which the bed 10 is facing may be given a finish (wallpaper, etc.) different from that of the surrounding area, so that it can be easily recognized that it can be used in place of a headboard. The bed 10 may be fixed to the floor 2 or the wall 4. In other words, the bed 10 may be a built-in bed.

[0036] The multiple wall portions 4 include a first wall portion 4a arranged with one end portion 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.

[0037] 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 multiple walls 4. A raised platform may be provided on the floor 2, and a futon may be laid on the top of the raised platform to be used in the same way as the bed 10.

[0038] The radiant heating and cooling device 12 is a device that radiates heat from the surface by circulating a high 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 brought together. The fluid may be, for example, water or an antifreeze liquid (such as 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 portion 4a in which the radiant heating and cooling device 12 is built in functions as a support for supporting the radiant heating and cooling device 12. The radiant heating and cooling device 12 may be built in the second wall portion 4b, in which case the second wall portion 4b also functions as a support. Furthermore, in this embodiment, the radiant heating and cooling device 12 is built into the wall portion 4, but this is not limited to the above, and the radiant heating and cooling device 12 may be built into the floor portion 2 or the ceiling portion 3. In other words, the floor portion 2 and the ceiling portion 3 may function as support bodies, or the radiant heating and cooling device 12 may be built into the floor portion 2 or the ceiling portion 3 with the wall portion 4 acting as a support body.

[0039] As described above, the radiant cooling and heating device 12 is built into the first wall portion 4a and is in an integrated state. Therefore, the first wall portion 4a may refer to both the wall body of the first wall portion 4a and the radiant cooling and heating device 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 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. Moreover, 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.

[0040] 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 preferable that the radiant heating and cooling device 12 is disposed above the upper surface of the bed 10. Since 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, 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 body of the bed 10 may have a height adjustment function.

[0041] The configuration of the radiant cooling and heating device 12 will be described in more detail. It comprises multiple cooling and heating 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 pass, for example, under the floor or above the ceiling, connecting the multiple cooling and heating panels 13 and the water source. The water supply source is connected to a heat exchange unit, which enables cold water to be circulated to the radiant heating and cooling device 12 in the summer and hot water to be circulated to the radiant heating and cooling device 12 in the winter. Furthermore, if multiple cooling and heating panels 13 are each supplied with fluid through a different system, it becomes possible to adjust the temperature of each cooling and heating panel 13 differently.

[0042] When such a radiant cooling and heating device 12 is incorporated into the first wall portion 4a, a plurality of cooling and heating panels 13 are incorporated into the framework that constitutes the first wall portion 4a. That is, if the framework of the house having the room space 1 is constructed by a conventional construction method, the first wall portion 4a will be composed of pillars, beams, etc. The multiple cooling and heating panels 13 may be directly attached and incorporated into the framework such as pillars and beams, or may be attached to a frame fixed to the framework. The multiple walls 4 are filled with a heat insulating material, and the multiple cooling and heating panels 13 are provided adjacent to the heat insulating material. When the framework of a house having a room space 1 is constructed using, for example, a framed wall construction method, a plurality of cooling and heating panels 13 are assembled between wooden pieces assembled in a frame shape. The radiant heating and cooling device 12 incorporated in the structure constituting the first wall portion 4a is shielded by the surface material constituting the wall surface of the first wall portion 4a facing the room space 1, and is not exposed to the room space 1.

[0043] 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 arranged close to the first wall 4a, the head of the user P located on the one end 10a side of the bed 10 is easily affected directly by the radiant heat from the radiant heating and cooling device 12, while the foot part located on the other end 10b side of the bed 10 is less likely to be affected directly by the radiant heat from the radiant heating and cooling device 12.

[0044] 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. Then, the temperature-adjusted air can 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 away from the radiant heating and cooling device 12, he or she can be warmed or cooled by natural convection in the room space 1. In other words, if the air flow (air current) in the room space 1 can be controlled, the radiant heat emitted from the radiant heating and cooling device 12 can be transported farther.

[0045] In this embodiment, the radiant heating and cooling device 12 is incorporated and supported in the first wall portion 4a of the multiple wall portions 4 that make up the room space 1, but it may also be incorporated and supported in a false wall 5 formed on the wall surface of the first wall portion 4a, as shown in Figure 2. The raised wall 5 includes a frame (not shown) constituting the raised wall 5, a surface material constituting the wall surface of the raised wall 5 facing the room space 1, and a cooling and heating panel 13 having a pipe material 13a for circulating a high-temperature or low-temperature fluid. The cooling and heating panel 13 is provided on the back side of the surface material and supported by the frame. As a result, the radiant cooling and heating device 12 is incorporated and supported in the raised wall 5. The raised wall 5 is formed on the wall surface of the first wall portion 4a and is disposed so as to protrude forward of the first wall portion 4a, so that if one end 10a of the bed 10 is disposed so as to be brought together, it is easily recognized by the user P as a headboard.

[0046] 2, by providing two raised walls 5 (radiant heating and cooling devices 12) in the room space 1, it is possible to differentiate the set temperature of the radiant heating and cooling device 12 in contact with one bed 10 (e.g. the husband's bed) from the set temperature of the radiant heating and cooling device 12 in contact with the other bed 10 (e.g. the wife's bed). If a couple has different comfortable temperatures, the room temperature of the room space 1 can become a cause of arguments, but by installing multiple radiant heating and cooling devices 12, personal air conditioning that realizes a comfortable temperature for each user P is possible, making it possible to avoid such arguments.

[0047] An air conditioning system including a radiant heating and cooling device 12 is provided in the room space 1 configured as above.

[0048] [Example] The air conditioning system for the room space 1 in this embodiment will be described in more detail below. In addition, in each embodiment of the air conditioning system described below, it is assumed that the room space 1 has the above-mentioned configuration. In addition, common elements are given common reference numerals, and the description will be omitted or simplified as appropriate.

[0049] Example 1-1 As shown in Figure 3, the room space 1 of this embodiment is provided 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.

[0050] More specifically, the first airflow control means 14 in this embodiment is an air blowing device 14 having 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. The plurality of air blowing devices 14 are arranged at intervals in the vertical direction.

[0051] Each air blowing device 14 has an outlet 14a for blowing air toward the room space 1, and each air blowing device 14 has a main body that blows air and is positioned behind the first wall portion 4a, with only the outlet 14a exposed to the room space 1. The air outlet 14a can adjust the volume and speed of air by changing the airflow direction up, down, left, and right, and narrowing or widening the opening range. That is, the air outlet 14a is provided with a plurality of fins for changing the airflow direction and shutters for narrowing or widening the opening range, as appropriate, although not shown. The operation of the air outlet 14a may be automatically controlled or may be manually changed. In addition, the main body of the air blowing device 14 can adjust the fundamental air volume. The air blowing device 14 may also have a function such as an on timer or an off timer. In addition, a remote control for controlling the operation of the air blowing device 14 may be provided.

[0052] In this embodiment, the air outlet 14a is set to a width dimension corresponding to two beds 10 placed at a distance from each other, but the width dimension may be set to correspond to each bed 10, and an air outlet 14a (air blowing device 14) may be provided corresponding to each bed 10. That is, by disposing the air outlets 14a (air blowing device 14) separately on the left and right and placing the beds 10 in front of these left and right air outlets 14a (air blowing device 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 heating and cooling device 12 is provided in the built-up wall 5, the air outlet 14a is also provided in the built-up wall 5.

[0053] In this embodiment, a plurality of radiant cooling and heating devices 12 are provided on the first wall portion 4a. The plurality of radiant cooling and heating devices 12 are arranged at intervals in the vertical direction. That is, a plurality of radiant cooling and heating devices 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 cooling and heating devices 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 cooling and heating device 12 is provided at the bottom, a radiant cooling and heating device 12 is also provided at the top, and two radiant cooling and heating devices 12 and three air blowing devices 14 (blowout ports 14a) are alternately provided between these radiant cooling and heating devices 12.

[0054] 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.

[0055] 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. Moreover, the air near the multiple radiant heating and cooling devices 12 is temperature-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 wind direction and air volume for each of the multiple air blowing devices 14 (air outlets 14a), it is possible to control the air flow in more diverse patterns. This allows the temperature-adjusted air to circulate to various places in the room space 1. In addition, if the set temperature is changed for each of multiple radiant heating and cooling devices 12 arranged vertically, air conditioning can be controlled in a more complex pattern.

[0056] One of the multiple patterns for controlling the flow of air whose temperature has been adjusted by the radiant heat from the multiple radiant cooling and heating 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, that is, by operating or stopping.

[0057] Since the bed 10 is arranged with one end 10a close to the first wall portion 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, 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 of the room space 1 can contribute not only 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.

[0058] In this embodiment, the first airflow control means 14 is an air blowing device 14, but is not limited to this and may be, for example, part of a ventilation system installed in a building, or an air conditioner capable of adjusting 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, a single air blowing device 14 may be used. In that 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.

[0059] [Example 1-2] As shown in Figures 4 to 6, the room space 1 of this embodiment is provided 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 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 a plurality of patterns.

[0060] 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 above the upper surface of the bed 10. The bed 10 is also installed such that one end portion 10a is located below the counter 15. In other words, the counter 15 is located above the head of the user P.

[0061] The counter 15 is configured 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.

[0062] 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 rails 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 portion can be disposed above the upper surface of the bed 10 with a space therebetween.

[0063] 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 4a in the horizontally disposed state is connected to a support slider 17.

[0064] 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.

[0065] 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 with respect to the wall surface of the first wall portion 4a. That is, when the counter 15 is used as the counter 15, it is disposed in a state in which it protrudes forward from the wall surface of the first wall portion 4a, but since 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 is composed of a slider body that slides along the guide rail 16, a fixed part that is fixed to the side end surface of the counter 15, and an angle adjustment part provided between the slider body and the fixed part. The angle adjustment part rotates the fixed part relative to the slider body in a side view, 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 the above, and the angle adjustment of the counter 15 relative to the wall surface of the first wall portion 4a may be limited to only two types: an angle at which the counter 15 is positioned horizontally, and an angle at which the counter 15 is rotated downward to align with the wall surface of the first wall portion 4a (in other words, a folded state).

[0066] As shown in FIG. 5, items such as a smartphone SP or an alarm clock AC are placed on the upper surface of the counter 15 and used; however, if the counter 15 is rotated downward so that it is aligned with the surface of the first wall portion 4a without noticing that an item is placed thereon, the item will naturally fall off. Therefore, the upper surface of the counter 15 is provided with a function for attaching articles. For the function of attaching articles, an adhesive sheet for repeatedly attaching articles, or a magnetic sheet for attaching metal parts of articles is appropriately adopted. Also, like a hook-and-loop fastener, not only the upper surface side of the counter 15 but also the article side may play a part in the attachment function.

[0067] The vertical movement and angle adjustment of the counter 15 are performed automatically or manually. 6, 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.

[0068] Further, the driving unit 18 is connected by wire or wirelessly to a control device 19 constituted by a computer, and is controlled by the control device 19. The control device 19 has a memory unit 20, and the memory unit 20 stores various programs and various data necessary for controlling the drive unit 18. The control device 19 is also configured to control the drive unit 18 according to the sensing result of a status detection sensor 21 provided in the room space 1.

[0069] Examples of the status detection sensor 21 include sensors that detect the state of the air environment in the room space 1, such as temperature, humidity, and air cleanliness, sensors that detect the illuminance under the counter 15, and sensors (which may include a camera or microphone) that non-contact detect the biometric information of user P (body temperature, blood pressure, blood flow, heart rate, complexion, sleep, breathing, sweat, etc.). 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.

[0070] 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 utilized, and the drive unit 18, control device 19, and status detection sensor 21 will be appropriately equipped with the necessary communication modules, etc.

[0071] According to the automatic control system for counter 15 configured in this manner, when the sensing result by status detection sensor 21 satisfies 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 and rotated relative to support slider 17. This allows counter 15 to be automatically moved up and down and its angle adjusted.

[0072] When manually moving the counter 15 up and down and adjusting the angle, the counter 15 is held by hand and slid upward or downward or rotated upward or downward. When the position of the counter 15 is determined, the stopper is manually operated to temporarily fix the counter 15.

[0073] 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.

[0074] 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 air near the radiant heating and cooling device 12 is temperature-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 15, which is the second airflow control means, is less likely to circulate directly below the counter 15. Furthermore, the air whose temperature is 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 cooling and heating device 12, air conditioning can be controlled in a more complicated pattern.

[0075] To explain in more detail, cooled air has a 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 cold air blocked by the counter 15 descends from the projection direction side end (and width direction side end) of the counter 15, and is therefore more likely to flow toward the feet of the user P than toward the head. By tilting the angle of the counter 15 downward, the speed at which the cold air descends can be improved. Conversely, by tilting the angle of the counter 15 upward, the descending cold air can be allowed to accumulate on the counter 15, and then slowly descend from the projection direction side end of the counter 15 or the end side of the first wall portion 4a. Furthermore, if the height position of the counter 15 is different, the airflow control will be different depending on the height position. Furthermore, the airflow control will also be different depending on the set temperature of the radiant heating and cooling device 12.

[0076] 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 effectively prevent the rising warm air from escaping. Warm air that has been temperature-adjusted below the counter 15 gradually rises from the end of the counter 15 in the protruding direction, but by slanting the angle of the counter 15 downward, it becomes easier for the air to stay under 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 is different, the airflow control will be different depending on the height position. Furthermore, the airflow control will also be different depending on the set temperature of the radiant heating and cooling device 12.

[0077] One of the multiple patterns for controlling the flow of air whose temperature has been adjusted by the 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 portion 4a. That is, the counter 15 can control the flow of air in at least two patterns, that is, by placing it in a state in which it protrudes vertically from the wall surface of the first wall portion 4a, or by folding it and placing it along the wall surface of the first wall portion 4a.

[0078] The air conditioning system for the room space 1 of this embodiment as described above can contribute not only to air conditioning the entire room space 1, but also to creating a good sleeping environment in the bed 10, one end 10a of which is positioned close to the first wall portion 4a.

[0079] In this embodiment, only one counter 15 is provided, but multiple counters 15 may be provided at intervals in the vertical direction. In this case, by making the protruding dimensions of the multiple counters 15 from the first wall portion 4a different, it becomes possible to control the air flow in more diverse patterns.

[0080] Furthermore, since the counter 15 can be slid up and down, when the first wall portion 4a (or the upper 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 upward so as not to get in the way.

[0081] [Examples 1-3] As shown in Figure 7, the room space 1 of this embodiment is provided 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 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.

[0082] More specifically, the third airflow control means 22 in this embodiment is a sheet material 22 suspended from the ceiling section 3 by wires 22a and 22b. The sheet material 22 is provided at a height position above the upper surface of the bed 10. The bed 10 is also installed such that one end portion 10a is located below the sheet material 22. In other words, the sheet material 22 is located above the head of the user P.

[0083] The material (fabric) of the sheet material 22 is not selected to have a "net"-like texture that allows a large amount of air to pass through due to its coarse mesh in order to control the airflow. In addition, in order to reduce the feeling of oppression, it is preferable that the material has high transparency or light transmittance, but it does not necessarily have to have high transparency or light transmittance. In addition, it is preferable that the material has a certain amount of weight because it is difficult to control the airflow if the material flutters widely when exposed to wind. It is preferable that the sheet material 22 used as the third airflow control means satisfies these conditions. However, it 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 made of a material that is easy to wash. Specifically, the sheet material 22 is preferably a cloth material that is a fiber material, but may also include a film material such as a vinyl film.

[0084] 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 hereinafter be referred to 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 hereinafter be referred to 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. In addition, in this embodiment, hanging threads (twisted / twisted fibrous material) are used as the first wire 22a and the second wire 22b, but this is not limited to this and may be wires such as strings, ropes, metal cables (wires), chains, etc.

[0085] The sheet material 22 is suspended at its four corners by the first wires 22a and the second wires 22b, and is therefore bent downwards except at the four corners. 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 of the sheet material 22 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 (the other side edge) from bending.

[0086] 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 conversely, by reeling them in 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 conversely, by reeling them in to shorten them.

[0087] 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 22a and the second wire 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 the storage unit. The control device is also configured to control the drive unit according to the sensing result of a state detection sensor 21 provided in the room space 1. According to the automatic control system for the sheet material 22 thus configured, when the sensing result by the state detection sensor 21 satisfies a certain condition, 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 appropriately wound and unwound by the winding device. 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.

[0088] When the vertical movement and angle adjustment of the sheet material 22 are performed manually, a 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 rotor of the winding device are allowed to hang down. If rods are provided as weights on one and the other side edges of the sheet material 22, and further, fasteners are attached to the middle parts of the first wire 22a and the second wire 22b, the sheet material 22 is placed at a certain height, and this position can be made the lowest position. When the sheet material 22 is raised, the ends of the first wire material 22a and the second wire material 22b hanging downward may be pulled downward. When the sheet material 22 is temporarily fixed in the raised position, the first wire material 22a and the second wire material 22b may be fastened to a hook portion protruding from the first wall portion 4a, for example.

[0089] 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 in front of which the sheet material 22 is disposed.

[0090] 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. Moreover, the air near the radiant heating and cooling device 12 is temperature-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 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 is 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 the 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 cooling and heating device 12, air conditioning can be controlled in a more complicated pattern.

[0091] 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. Since the sheet material 22 is not attached to the first wall portion 4a, the cold air blocked by the sheet material 22 descends from the peripheral portion of the sheet material 22. The cold 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. By slanting the angle of the sheet material 22 downward (the other side edge is lower than the one side edge), the descending speed of the cold air toward the toes of the user P can be improved. Conversely, by slanting the angle of the sheet material 22 upward (the other side edge is higher than the one side edge), the descending speed of the cold air toward the head of the user P can be improved. Moreover, if the height position of the sheet material 22 is different, the control of the airflow will be different depending on the height position. Furthermore, the control of the airflow will also be different depending on the set temperature of the radiant heating and cooling device 12.

[0092] 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 it is desired to cause warm air to stagnate below the sheet material 22, a pulling string (not shown) is connected to the center of the sheet material 22, and the string is pulled upward and then tied to, for example, a hook portion protruding from the first wall portion 4a. This allows the sheet material 22 to be inflated upward, so that warm air can stagnate below the sheet material 22. In addition, by slanting the angle of the sheet material 22 downward or upward, the warm air that has accumulated below the sheet material 22 can be gradually released upward. Moreover, if the height position of the sheet material 22 is different, the control of the airflow will be different depending on the height position. Furthermore, the control of the airflow will also be different depending on the set temperature of the radiant heating and cooling device 12.

[0093] The air conditioning system for the room space 1 of this embodiment as described above can contribute not only to air conditioning the entire room space 1, but also to creating a good sleeping environment in the bed 10, one end 10a of which is positioned close to the first wall portion 4a.

[0094] In this embodiment, only one sheet material 22 is provided, but 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 more diverse patterns.

[0095] Furthermore, since the sheet material 22 can be moved in the vertical direction, when the first wall portion 4a (or the upper 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 as not to get in the way.

[0096] In the present embodiment, the sheet material 22 is formed in a rectangular shape with the wires 22a, 22b connected to the four corners, but this is not limited thereto, and the sheet material 22 may be formed in other polygonal shapes such as a triangular shape or a pentagonal shape with the wires 22a, 22b connected to the respective corners. In any case, however, in order to ensure the function as the airflow control means, it is desirable that the sides, not the corners, of the sheet material 22 are arranged along the wall surface of the first wall portion 4a.

[0097] [Examples 1-4] As shown in Figure 8, the room space 1 of this embodiment is provided 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 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 a plurality of patterns.

[0098] 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 above the upper surface of the bed 10. The bed 10 is also installed such that one end portion 10a is located below the curved counter 23. In other words, the curved counter 23 is located above the head of the user P.

[0099] The curved counter 23 is curved so as to bulge downward in a side view, and the protruding side end portion opposite the first wall portion 4a faces upward. The width of the curved counter 23 is set to be approximately equal to the width of the bed 10.

[0100] The end of the curving counter 23 on the first wall 4a side is bridged across a plurality of supports 24 provided at intervals on the wall surface of the first wall 4a, and is connected via a rotating shaft. That is, the curving 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 curving counter 23 to rotate vertically and adjust the angle.

[0101] Although the curvature 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.

[0102] 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.

[0103] 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 air near the radiant heating and cooling device 12 is temperature-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 curved counter 23, which is the fourth airflow control means, is less likely to circulate directly below the curved counter 23. Furthermore, the air whose temperature is 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 cooling and heating device 12, air conditioning can be controlled in a more complicated pattern.

[0104] 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 cold air blocked by the curved counter 23 descends from the protruding direction end (and width direction end) of the curved counter 23, so it is more likely to flow toward the toes of the user P than toward the head. By tilting the angle of the curved counter 23 downward (a state in which the protruding direction end is located below the support part 24), the descending speed of the cold air can be improved. In particular, since the protruding direction end is in an upward state as described above, the cold air can be sent far away with force depending on the descending speed of the cold air. On the other hand, by tilting the angle of the curved counter 23 upward (a state in which the protruding direction end is located above the support part 24), it is possible to make a large amount of the descending cold air remain on the curved counter 23. The large amount of accumulated cold air can be slowly descended from the protruding direction end side or the first wall part 4a side end side of the curved counter 23.

[0105] On the other hand, heated air has a 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 escape easily. By inclining the angle of the curved counter 23 upward, warm air can escape upward more quickly.

[0106] The air conditioning system for the room space 1 of this embodiment as described above can contribute not only to air conditioning the entire room space 1, but also to creating a good sleeping environment in the bed 10, one end 10a of which is positioned close to the first wall portion 4a.

[0107] In this embodiment, only one curved counter 23 is provided, but 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.

[0108] [Examples 1 to 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 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.

[0109] More specifically, the fifth airflow control means 25 in this embodiment is a counter 25 provided to protrude from the wall surface of the second wall portion 4b forward of the first wall portion 4a. The counter 25 is provided at a height position above the upper surface of the bed 10. The bed 10 is also installed such that one end portion 10a is located below the counter 25. In other words, the counter 25 is located above the head of the user P.

[0110] The counter 25 is made of a rectangular plate material, and a lower end portion of the counter 25 is attached to the second wall portion 4b that is perpendicular to the first wall portion 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. That is, the counter 25 is configured to rotate in the vertical direction around the rotating shaft at the lower end.

[0111] At the lowest position, the counter 25 abuts against the lower edge of the storage recess 4c and is arranged horizontally. An auxiliary bracket (not shown) that abuts against the wall surface of the second wall 4b like a diagonal brace may be attached to the lower surface 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 bottom surface 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.

[0112] The second wall portion 4b to which the counter 25 as 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 in a plan view, has a radiant heating and cooling device 12 built in and supported therein.

[0113] 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. Moreover, the air near the radiant heating and cooling device 12 has its temperature 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 25, which is the fifth airflow control means, is less likely to circulate directly below the counter 25. Furthermore, the air whose temperature has been 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.

[0114] To explain in more detail, cooled air has a 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 direction side (and the end on the foot side of the user P), and is therefore more likely to flow toward the foot side of the user P than toward the head side.

[0115] 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 effectively prevent the rising warm air from escaping.

[0116] The air conditioning system for the room space 1 of this embodiment as described above can contribute not only to air conditioning the entire room space 1, but also to creating a good sleeping environment in the bed 10, one end 10a of which is positioned close to the first wall portion 4a.

[0117] In this embodiment, the counter 25 can control the air flow in two patterns, either by protruding vertically from the second wall 4b or by storing it in the storage recess 4c and lining it up with the wall surface of the second wall 4b, but it may be configured so that its angle is adjustable. In that case, by adjusting the angle of the counter 25, it becomes possible to control the air flow in more diverse patterns.

[0118] Furthermore, the counter 25 can be stored in the storage recess 4c of the second wall 4b. Therefore, when the first wall 4a (or the upper 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 does not get in the way.

[0119] [Examples 1 to 6] As shown in FIG. 10, the room space 1 of this embodiment is provided 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 a plurality of patterns.

[0120] More specifically, the sixth airflow control means 26 in this embodiment is a counter 26 provided to protrude 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 such that one end portion 10a is located below the counter 26. In other words, the counter 26 is located above the head of the user P.

[0121] 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. Moreover, the counter 26 is formed to be hollow, and the cooling and heating panel 13 is provided in the hollow portion. That is, the counter 26 functions as a radiant cooling and heating device.

[0122] The cooling and heating panel 13 provided in the hollow portion of the counter 26 is adapted to receive a fluid supply from a system different from that of the cooling and heating panel 13 constituting the radiant heating and cooling device 12 that is built into and supported by the first wall portion 4a. This allows different temperature control for the counter 26 that functions as a radiant heating and cooling device and the radiant heating and cooling device 12 on the first wall portion 4a side.

[0123] The cooling and heating panel 13 provided in the hollow portion of the counter 26 has a circulation pipe passing through the first wall portion 4a and connected to a water supply source. Therefore, the counter 26 in this embodiment is configured not to be moved up and down or to have its angle adjusted.

[0124] 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. Moreover, 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.

[0125] In this embodiment, the air flow can be controlled by appropriately changing the temperature adjustment (including on / off) by the radiant heating and cooling device 12 and the temperature adjustment (including on / off) by the counter 26 which functions as a radiant heating and cooling device.

[0126] To explain in more detail, by combining operating states in which only the radiant heating and cooling device 12 is operated in cooling or heating mode, only the counter 26 functioning as a radiant heating and cooling device is operated in cooling or heating mode, and both the radiant heating and cooling device 12 and the counter 26 are operated in cooling or heating mode, and by separately adjusting the temperature, it is possible to control the air flow in a variety of patterns without moving the counter 26 up and down or adjusting the angle.

[0127] The air conditioning system for the room space 1 of this embodiment as described above can contribute not only to air conditioning the entire room space 1, but also to creating a good sleeping environment in the bed 10, one end 10a of which is positioned close to the first wall portion 4a.

[0128] [Examples 1 to 7] 11 shows an example of the arrangement of airflow control means for a plurality of cooling and heating panels 13 with pipes 13a piped therein. The pipes 13a are arranged inside the cooling and heating panels 13 in a serpentine manner. In addition, at least a surface material (a building board material such as plywood or a fire-resistant covering material such as gypsum board) that constitutes the wall surface of the first wall portion 4a is interposed between the multiple cooling and heating panels 13 and the airflow control means.

[0129] 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 constituting the wall surface of the first wall portion 4a by a fixing material B such as a screw. At that time, the fixing material B is driven in while avoiding the meandering pipe material 13a, as shown in FIG. 11(a).

[0130] The airflow control means shown in Figure 11 (b) is a counter that is arranged so as to be movable up and down on the wall surface of the first wall portion 4a, and the counter is arranged so as to be slidable 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 constituting the wall surface of the first wall portion 4a by a fixing material B such as a screw. At that time, the fixing material B is driven in while avoiding the meandering pipe material 13a, as shown in FIG. 11(b).

[0131] [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 provided on a counter 29. A humidifier 31 is also provided on the counter 29 to prevent the user P from becoming dry in winter. In addition, the counter 29 in this embodiment can be moved up and down and its angle adjusted as required.

[0132] A recess 29a is formed on the underside of the counter 29, and the non-contact thermometer 30 and the humidifier 31 are attached and stored 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 above-mentioned condition detection sensor. The humidifier 31 can be used not only for health management of the user P and for countermeasures against dryness in winter, but also as one function of the air conditioning system in the room space 1. That is, the humidity can be adjusted by operating the humidifier 31. The humidifier 31 is provided in a set with a tank 31a that can be removed from the recess 29a.

[0133] By thus endowing the airflow control means with a health management function for user P, 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, one end 10a of which is positioned close to the first wall portion 4a.

[0134] In this embodiment, a non-contact thermometer 30 that measures the body temperature of user P is used on the counter 29. However, instead of the non-contact thermometer 30, a biosensor (which may include a camera and microphone) that detects the biometric information of user P (body temperature, blood pressure, blood flow, heart rate, complexion, sleep, breathing, sweat, etc.) in a non-contact manner may be used.

[0135] In addition, in this embodiment, the humidifier 31 is provided on the counter 29, but a dehumidifier (not shown) may be provided instead of the humidifier 31 or together with the humidifier 31. By providing a dehumidifier, dehumidification can be performed in the summer or rainy season, which contributes to creating a good sleeping environment.

[0136] According to this embodiment, the following excellent effects are obtained. That is, the airflow in the room space 1 is controlled in a plurality of patterns by the airflow control means 14, 15, 22, 23, 25, 26, 27, and 29, so that the airflow can be prevented from always being constant. This allows air whose temperature has been adjusted by the radiant heat from the radiant heating and cooling device 12 to be circulated widely in the room space 1, so that a comfortable thermal environment can be formed in the room space 1.

[0137] In addition, the air blowing device 14, which 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 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.

[0138] Furthermore, since the support 4 is the wall portion 4 constituting the room space 1, and the radiant cooling / heating device 12 and the air blowing device 14 are arranged one above the other, cold air having a descending property and warm air having an ascending property 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. That is, for example, if the air blowing device 14 is arranged below the radiant cooling / heating device 12, cold air having a descending property can be easily circulated widely within the room space 1, and if the air blowing device 14 is arranged above the radiant cooling / heating device 12, warm air having an ascending property can be easily circulated widely within the room space 1.

[0139] In addition, the airflow control means 15, 22, 23, 25, 26, 27, 29 are arranged in front of the support 4 and are configured to be able to change their position relative to the surface of the support 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 changing the position of the airflow control means 15, 22, 23, 25, 26, 27, 29.

[0140] 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 depending on the angle of the counters 15, 23, 25, 26, 27, and 29.

[0141] In addition, the counters 15, 23, 25, 26, 27, and 29 are capable of moving 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.

[0142] In addition, the counter 23 is curved so as to bulge downward in side view, and the protruding side 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 side end. Furthermore, by tilting the angle of the counter 23 upward, it becomes easier to accumulate a large amount of the descending cold air on the counter 23.

[0143] In addition, the airflow control means 15, 23, 25, 26, 27, 29 are directly or indirectly fixed to the surface of the support 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 in the radiant heating and cooling device 12 incorporated in the support 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.

[0144] In addition, the sheet material 22 suspended from the ceiling 3 and positioned in front of the wall 4 can move 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.

[0145] In addition, the control device 19 controls the operation of the airflow control means 15, 22, 23, 25, 26, 27, and 29 in accordance with the sensing results of the status detection sensor 21 installed in the room space 1, making it possible to perform optimal control in accordance with the status of the room space 1, and automatically create a comfortable thermal environment in the room space 1.

[0146] <Second embodiment> Next, a second embodiment will be described with reference to the drawings. For convenience of explanation, elements common to the first embodiment will be denoted by the same reference numerals, and explanations thereof will be omitted or simplified.

[0147] 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, a child's room, or a guest room in a house. The room space 1 is surrounded and formed 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 provided in the room space 1 configured as above.

[0148] [Example] The air conditioning system for the room space 1 in this embodiment will be described in more detail below. In addition, in each embodiment of the air conditioning system described below, it is assumed that the room space 1 has the above-mentioned configuration. In addition, common elements are given common reference numerals, and the description will be omitted or simplified as appropriate.

[0149] Example 2-1 In the room space 1 of this embodiment, in order to create a comfortable enclosed space when sleeping, a first covering body 32 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 13.

[0150] The underside of the first covering body 32 is curved upward in a side cross-sectional view, and has a first curved region 32b that gradually curves upward from a 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 protruding direction end (tip end) of the first cover 32 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.

[0151] A 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. Moreover, the first cover 32 is configured to be as lightweight as possible by adopting, for example, 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.

[0152] The upper surface of the first covering body 32 is provided with a counter plate material 33 to form a horizontal surface on which items can be placed. The counter plate material 33 also adopts, for example, a honeycomb structure or a flush structure, and is constructed to be as lightweight as possible.

[0153] In this embodiment, the first covering body 32 is constructed to be as lightweight as possible by adopting, for example, 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 resins.

[0154] 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 on both widthwise ends of the first covering body 32 to enhance isolation from the outside, or there may be no side walls and the end is open.

[0155] 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. In addition, the first covering 32 also functions as an air diffusion means for diffusing the indoor air, the temperature of which has been adjusted by radiant heat from the radiant heating and cooling device 12, to a location farther away from the radiant heating and cooling device 12.

[0156] 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. Moreover, the air near the radiant heating and cooling device 12 is temperature-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.

[0157] 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 direction side end (and width direction side end) of the first covering body 32, and is therefore more likely to flow toward the feet of the user P than toward the head.

[0158] On the other hand, heated air has a tendency to rise. Air that has been temperature-adjusted at a position below the first covering body 32 is less likely to circulate directly above the first covering body 32, so for those who want to prevent warm air from escaping, the first covering body 32 can minimize the escape of the rising warm air. In other words, warm air that has been temperature-adjusted at a position below the first covering body 32 is more likely to remain on the curved lower surface of the first covering body 32, so it is possible to minimize the escape of the rising warm air.

[0159] The air conditioning system for the room space 1 of this embodiment as described above can contribute not only to air conditioning the entire room space 1, but also to creating a good sleeping environment in the bed 10, one end 10a of which is positioned close to the first wall portion 4a. In particular, the first covering body 32 is curved upward from the lower end 32d at the base end to the lower end 32e at the tip end in a side view (side cross-sectional view), so that the space can be expanded upward for the user P who places his / her head below. This makes it difficult for the user P to feel a sense of oppression compared to, for example, a case in which the first covering body 32 is flat and not curved from the lower end 32d at the base end to the lower end 32e at the tip end. Therefore, it is possible to form a closed space that can adequately cover the head of the user P.

[0160] In this embodiment, the first cover 32 is configured not to move up and down or adjust the angle, but is not limited to this, and may be provided to be movable in the up and down direction along the wall surface of the first wall 4a, or may be provided to be angle-adjustable with respect to the wall surface of the first wall 4a. Alternatively, the first cover 32 may be rotated upward to be angle-adjustable in a state along the wall surface of the first wall 4a (in other words, a folded state).

[0161] Example 2-2 In the room space 1 of this embodiment, in order to create a comfortable enclosed space when sleeping, a second covering body 34 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.

[0162] The lower surface of the second covering body 34 is curved upward in a side cross-sectional view, and has a first curved region 34b that gradually curves upward from a lower end portion 34d at the portion (base end) on the first wall portion 4a side toward the other end portion 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 portion 10b of the bed 10 to reach a lower end portion 34e at the protruding direction side end portion (tip end). Further, a lower end 34d at the base end of the second cover 34 and a lower end 34e at the protruding direction end (tip end) of the second cover 34 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 to set the apex 34a to be located above the user P's head.

[0163] A 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. Moreover, the second cover 34 is constructed as light as possible by adopting, for example, 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.

[0164] The upper surface of the second covering body 34 is formed to be gradually curved downward from the first wall portion 4a side toward the tip end side. In other words, the upper surface of the second covering body 34 is gently inclined downward from the upper end portion at the portion on the first wall portion 4a side (base end portion) toward the protruding direction side end portion (tip portion).

[0165] 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 on both widthwise ends of the second covering body 34 to enhance isolation from the outside, or there may be no side walls and the end is open.

[0166] 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 radiant heat from the radiant heating and cooling device 12, to a location farther away from the radiant heating and cooling device 12.

[0167] 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. Moreover, the air near the radiant heating and cooling device 12 is temperature-adjusted by radiant heat from the radiant heating and cooling device 12. Then, 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.

[0168] 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 direction side end (and width direction 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.

[0169] 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 flow 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 the 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 the rising warm air can be minimized.

[0170] The air conditioning system for the room space 1 of this embodiment as described above can contribute not only to air conditioning the entire room space 1, but also to creating a good sleeping environment in the bed 10, one end 10a of which is positioned close to the first wall portion 4a. In particular, the portion between the lower end 34d at the base end of the second covering body 34 and the lower end 34e at the tip end is curved upward in a side view (side cross-sectional view), so that the space can be expanded upward for the user P who places his / her head below. This makes it difficult for the user P to feel a sense of oppression compared to, for example, a case in which the portion between the lower end 34d at the base end of the second covering body 34 and the lower end 34e at the tip end is a flat ceiling surface that is not curved. Therefore, it is possible to form a closed space that can adequately cover the head of the user P.

[0171] In this embodiment, the second cover 34 is configured not to move up and down or adjust the angle, but is not limited to this, and may be provided to be movable in the up and down direction along the wall surface of the first wall portion 4a, or may be provided to be angle-adjustable with respect to the wall surface of the first wall portion 4a. Alternatively, the second cover 34 may be rotated upward to be angle-adjustable in a state where it is aligned with the wall surface of the first wall portion 4a (in other words, a folded state).

[0172] 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.

[0173] The illuminated wall 35 has a recess 35a formed at the upper end, and the illumination device 36 is provided in the recess 35a. The upper opening of the recess 35a is closed by a light-transmitting lid 36a. An article can be placed on the upper 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 cover 36a, and can illuminate the enclosed space as indirect lighting. That is, the light emitted from the lighting device 36 hits the underside of the second covering body 34 and becomes a soft light. As a result, the feeling of oppression in the space below the second covering body 34 is reduced, making it a relaxing space. In addition, because the bottom surface of the second covering body 34 is curved, the light illuminating the enclosed space is less likely to leak outward (toward the feet) from the end on the protruding side. Therefore, the light from the lighting device 36 is less likely to reach people outside the second covering body 34, which contributes to the creation of a good sleeping environment for people outside the second covering body 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 environment for waking up.

[0174] Incidentally, 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. Even in the case of an acoustic device, sound is unlikely to leak outward (towards the feet) from the end on the protruding direction side. Therefore, sound from the acoustic device is unlikely to reach people outside the second covering 34, which can contribute to the creation of a good sleeping environment for people outside the second covering 34. In addition, by using the lighting device 36 in combination with an audio device, for example, by setting the lighting device 36 to emit light and the audio device to emit sound when getting up, it is possible to help the user get up comfortably.

[0175] Example 2-3 In the room space 1 of this embodiment, in order to create a comfortable enclosed space when sleeping, a third covering body 37 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.

[0176] 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 (base end) on the first wall portion 4a side toward the other end 10b of the bed 10 to reach 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 to reach the lower end at the protruding direction side end (tip end). The upper surface of the third cover 37 is formed so as to be gradually curved downward from the first wall portion 4a side toward the tip end side.

[0177] As shown in FIG. 16, both widthwise side ends 37f of the third cover 37 are located below the apex 37a, which is the highest point on the lower surface of the third cover 37. More specifically, the underside of the third covering body 37 in this embodiment curves upward in a vertical cross section, and gradually curves downward from the apex 37a toward both widthwise ends 37f. Both widthwise ends 37f are set at a height position substantially equal to the lower end 37d at the base end and / or the lower end at the tip end of the third covering body 37. As a result, the underside of the third covering body 37 is formed in a dome shape in a side cross section and an vertical cross section, so that the space below the third covering body 37 is highly isolated from the outside.

[0178] In this embodiment, the lower surface of the third covering body 37 is curved upward in the vertical cross section, but this is not limited thereto, and the lower surface does not have to be curved upward in the vertical cross section. That is, both widthwise end portions 37f of the third covering body 37 may be formed with sidewall portions formed to hang down in the vertical direction. In this case, the third covering body 37 is formed in a downward U-shape (with the open part of the U-shape facing downward) in the vertical cross section.

[0179] Furthermore, a plurality of slits 37g are formed in the third cover 37, penetrating the third cover 37 in the thickness direction. The plurality of slits 37g communicate with the space above and the space below the third cover 37. Therefore, air and lines of sight can pass through in the vertical direction through the plurality of slits 37g.

[0180] A 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. Moreover, the third cover 37 is configured to be as lightweight as possible by adopting, for example, a honeycomb structure or a flush structure so as to ensure a long protruding dimension from the first wall portion 4a.

[0181] By forming and providing the third covering body 37 in the above manner, an enclosed space can be secured within the room space 1.

[0182] The radiant heating and cooling device 12 is incorporated and supported on the first wall portion 4a to which the third cover 37 is attached. In addition, the third cover 37 also functions as an air diffusion means for diffusing the indoor air, the temperature of which has been adjusted by radiant heat from the radiant heating and cooling device 12, to a location farther away from the radiant heating and cooling device 12.

[0183] 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 the tendency to descend. Air (cold air) whose temperature has been adjusted at a position above the third covering body 37 flows directly below the third covering body 37 through the multiple slits 37g. Furthermore, the cold air that does not enter the multiple slits 37g is blocked by the third covering body 37 and flows along the upper surface of the third covering body 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 stays on the curved lower surface of the third covering body 37, but circulates to just above the third covering body 37 through the multiple slits 37g. This allows the heat in the enclosed space to escape, preventing heat from building up in the enclosed space.

[0184] The air conditioning system for the room space 1 of this embodiment as described above can contribute not only to air conditioning the entire room space 1, but also to creating a good sleeping environment in the bed 10, one end 10a of which is positioned close to the first wall portion 4a. In particular, the third cover 37 has both widthwise end portions 37f positioned below the apex 37a, which is the highest point on the underside of the third cover 37, so that the space can be expanded upward for the user P who places his / her head below the apex 37a. 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 makes it even less likely that the user will feel a sense 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 a feeling of oppression is less likely to be felt compared to, for example, a case in which the area between both widthwise ends of the third covering body 37 is a flat, uncurved ceiling surface.

[0185] In this embodiment, the third cover 37 is configured not to move up and down or adjust the angle, but is not limited to this, and may be provided to be movable in the up and down direction along the wall surface of the first wall 4a, or may be provided to be angle-adjustable with respect to the wall surface of the first wall 4a. Alternatively, the third cover 37 may be rotated upward to be angle-adjustable in a state where it is aligned with the wall surface of the first wall 4a (in other words, a folded state).

[0186] Also, the multiple slits 37g may be formed so that the slit width becomes wider as it gets farther from the wall surface of the first wall portion 4a. Also, the number of slits may increase as it gets farther from the wall surface of the first wall portion 4a. Furthermore, multiple through holes other than the slits 37g may be formed as it gets farther from the wall surface of the first wall portion 4a. As a result, the area of ​​the openings formed in the third cover 37 becomes wider as it gets farther from the wall surface of the first wall portion 4a, so that the cool air whose temperature has been adjusted at a position above the third cover 37 can be evenly sent to the toes of the user P.

[0187] According to this embodiment, the following excellent effects are obtained. That is, since the radiant heating and cooling device 12 is incorporated and supported in the wall portion 4 to which the coverings 32, 34, 37 (first covering 32, second covering 34, third covering 37) 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 coverings 32, 34, 37 can be made to flow down from the protruding side end along the upper surface 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 surface 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 by using the air temperature-adjusted by the radiant heating and cooling device 12. Furthermore, since the undersides of the covering bodies 32, 34, 37 protruding forward from the wall surface of the wall portion 4 are curved upward in a side cross-sectional view, the user P who uses the space below the covering bodies 32, 34, 37 feels as if the space below is expanded upward. As a result, the user is less likely to feel oppressive compared to, for example, a case in which the undersides of the covering bodies 32, 34, 37 are a flat ceiling surface that is not curved, so that a moderately enclosed space with a reduced feeling of oppression can be ensured.

[0188] Furthermore, the underside of the covering body 32, 34, 37 (first covering body 32, second covering body 34, third covering body 37) is formed to have a first curved region 32b, 34b, 37b that gradually curves upward from the lower end portion 32d, 34d, 37d at the base end of the covering body 32, 34, 37 toward the highest vertex 32a, 34a, 37a of the underside, and a second curved region 32c, 34c that gradually curves downward from the vertex 32a, 34a, 37a toward the lower end portion 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 side cross section.

[0189] Moreover, the covering body 37 (third covering body 37) is formed in such a state that both widthwise end portions 37f of the covering body 37 are positioned lower than the apex 37a, so that for a user P who uses the space below the covering body 37, the sides of the lower space are covered by both widthwise end portions 37f of the covering body 37. As a result, the lower surface of the covering body 37 is formed as if in a dome shape, so that a moderately enclosed space with reduced oppressive feeling can be secured.

[0190] 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, allowing air and lines of sight to escape in the vertical direction through the plurality of slits 37g, thereby ensuring an appropriately enclosed space that is less likely to cause a feeling of oppression. 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 protruding direction side end along the upper surface of the covering bodies 32, 34, and 37. Moreover, 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 directly above the third covering 37 through the multiple slits 37g. This allows the heat in the space below the covering 37 to be gradually released while heating the space below the covering 37, thereby preventing heat from building up in the enclosed space.

[0191] 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 lower surface 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. Since the light emitted from the lighting device 36 becomes a soft light when it hits the lower surface of the covering body 34, the feeling of oppression in the space below the covering body 34 is reduced, making it a calm space and improving the comfort of the enclosed space.

[0192] Furthermore, since 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 lower surface of the covering body 34 (second covering body 34), the sound emitted upward from the acoustic device reverberates in the space below the covering body 34 and is less likely to leak out from the space below the covering body 34. On the other hand, since sound from outside is less likely to reach the user P who uses the space below the covering body 34, the comfort of the enclosed space can be improved in terms of acoustics as well. <Third embodiment> Next, a third embodiment will be described with reference to the drawings. For convenience of explanation, elements common to the first and second embodiments are denoted by the same reference numerals, and explanations thereof will be omitted or simplified.

[0193] 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, a child's room, or a guest room in a house. The room space 1 is surrounded and formed 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 provided in the room space 1 configured as above.

[0194] [Example] The air conditioning system for the room space 1 in this embodiment will be described in more detail below. In addition, in each embodiment of the air conditioning system described below, it is assumed that the room space 1 has the above-mentioned configuration. In addition, common elements are given common reference numerals, and the description will be omitted or simplified as appropriate.

[0195] 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 cooling and heating device 12. The first air diffusion means 38 has a passage portion 38a that allows a line of sight and air to pass through in the vertical direction.

[0196] More specifically, the first air diffusion means 38 in this embodiment is a counter 38 provided to protrude from the wall surface of the first wall portion 4a. The counter 38 is provided at a height position above the upper surface of the bed 10. The bed 10 is also installed such that one end portion 10a is located below the counter 38. In other words, the counter 38 is located above the head of the user P.

[0197] The counter 38 is made up of a plurality of divided plates 38b arranged at intervals in the width direction on the wall surface of the first wall portion 4a. In this embodiment, three divided plates 38b are arranged at intervals in the width direction on the wall surface of the first wall portion 4a, and the gaps 38a between these three divided plates 38b form passages 38a that allow the line of sight and air to pass through in the vertical direction. The divided plate body 38b is made of a rectangular plate material, and the dimension from the outer surface to the outer surface of the divided plate body 38b on both sides is set to be approximately equal to the width dimension of the bed 10. The central divided plate body 38b is located above the center of the bed 10 in the width direction.

[0198] 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.

[0199] 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 air near the radiant heating and cooling device 12 is temperature-adjusted by radiant heat from the radiant heating and cooling device 12. Cooled air has the tendency to descend. The air (cold air) whose temperature has been adjusted at a position above the counter 38 flows through the multiple passing sections 38a between the multiple divided plates 38b to the area directly below the divided plates 38b (i.e., the counter 38). The cold air that does not enter the multiple passing sections 38a is blocked by the multiple divided plates 38b and flows along the upper surfaces of the multiple divided plates 38b to the foot side. On the other hand, heated air has the tendency to rise. The air (warm air) whose temperature has been adjusted at a position below the counter 38 flows through the multiple passing sections 38a between the multiple dividing plates 38b to directly above the dividing plates 38b (i.e., the counter 38). The warm air that does not enter the multiple passing sections 38a is blocked by the multiple dividing plates 38b and temporarily remains on the lower surfaces of the multiple dividing plates 38b, but flows directly above the multiple dividing plates 38b through the multiple passing sections 38a. This allows heat to escape from the space directly below the counter 38, preventing heat from building up in the space.

[0200] The air conditioning system for the room space 1 of this embodiment as described above can contribute not only to air conditioning the entire room space 1, but also to creating a good sleeping environment in the bed 10, one end 10a of which is positioned close to the first wall portion 4a. In particular, the counter 38 is composed of multiple divided plates 38b arranged at intervals from each other, and the gaps between the multiple divided plates 38b form passages 38a that allow line of sight and air to pass through in the vertical direction, so that a user P with his / her head below the passage is less likely to feel oppressed compared to a case in which line of sight and air cannot pass through. In addition, the multiple divided plates 38b can effectively diffuse cool air whose temperature has been adjusted above the counter 38 and warm air whose temperature has been adjusted below the counter 38.

[0201] In this embodiment, the counter 38 is configured not to move up and down or adjust the angle, but is not limited to this, and may be provided to be movable in the up and down direction along the wall surface of the first wall portion 4a, or may be provided to be angle-adjustable with respect to the wall surface of the first wall portion 4a. Alternatively, the counter 38 may be configured to be rotated upward and angle-adjustable to a state along the wall surface of the first wall portion 4a (in other words, a folded state). When configured to allow up and down movement and angle adjustment, the multiple divided plate bodies 38b may be capable of being moved up and down and adjusted in angle separately, or may be capable of being moved up and down and adjusted in angle all at once.

[0202] In this embodiment, the counter 38 is composed of a plurality of divided plates 38b, and the gaps between these plurality of divided plates 38b are defined as passages 38a that allow the passage of lines of sight and air 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 of counters 39, 40, 41 provided so as to protrude from the wall surface of the first wall portion 4a.

[0203] A counter 39 shown in FIG. 18(a) has a circular arc-shaped cutout 39a, which serves as a passage 39a through which lines of sight and air can pass in the vertical direction. The cutout portion 39a, which is the passage portion 39a, is formed in a semicircular shape in the center of the counter 39 in the width direction, so that the head of the user P located directly below is not completely covered by the counter 39.

[0204] 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 passage sections 40a that allow line of sight and air to pass through in the vertical direction. The multiple slits 40a, which are the passage sections 40a, are arranged at intervals in the direction in which the counter 40 protrudes from the wall surface of the first wall section 4a, so that the head of a user P positioned directly below is not completely covered by the counter 40.

[0205] The counter 41 shown in FIG. 18(c) has a plurality of through holes 41a formed by penetrating the board material of the counter 41 in the thickness direction, which serve as passages 41a that allow the passage of lines of sight and air in the vertical direction. The plurality of through holes 41a serving as the passage portions 41a are arranged in a staggered pattern, so that the head of the user P positioned directly below is not completely covered by the counter 41.

[0206] The air (cold air) whose temperature has been adjusted above the counters 39, 40, 41 flows through the passages 39a, 40a, 41a to the area directly below the counters 39, 40, 41. The cold air that does not enter the passages 39a, 40a, 41a is blocked by the counters 39, 40, 41 and flows along the upper surfaces of the counters 39, 40, 41 to the feet side. Meanwhile, air (warm air) that has been temperature-adjusted below the counters 39, 40, 41 circulates through the passing sections 39a, 40a, 41a to directly above the counters 39, 40, 41. Also, the warm air that does not enter the passing sections 39a, 40a, 41a is blocked by the counters 39, 40, 41 and temporarily stagnates on the underside of the counters 39, 40, 41, but then circulates through the passing sections 39a, 40a, 41a to directly above the counters 39, 40, 41. This allows heat to escape from the space directly below the counters 39, 40, 41, preventing heat from building up in the space.

[0207] Example 3-2 19, the room space 1 of this embodiment is provided with a second air diffusion means 42 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 cooling and heating device 12. The second air diffusion means 42 has a passage portion 42a that allows a line of sight and air to pass through in the vertical direction.

[0208] 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 above the upper surface of the bed 10. The bed 10 is also installed such that one end portion 10a is located below the counter 42. In other words, the counter 42 is located above the head of the user P.

[0209] Counter 42 has a bulge portion 43 formed by bulging downward in the widthwise center of the rectangular plate material that constitutes counter 42, and a cutout portion 43a is formed in the lowest position of this bulge portion 43. The bulging portion 43 is formed to gently incline 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. The bottom plate of the bulging portion 43 is cut out in a U-shape in a plan view to form a notch 43a. The notch 43a serves as a passage 43a through which lines of sight and air can pass in the vertical direction.

[0210] 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 become longer toward the wall surfaces of the first wall 4a. In other words, these side walls 44 function as brackets that support the counter 42.

[0211] 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.

[0212] 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. In addition, the air near the radiant heating and cooling device 12 is temperature-adjusted by radiant heat from the radiant heating and cooling device 12. Cooled air has the 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 the passage 43a formed by a notch at the lower end of the bulging portion 43. The upper surface of the bulging portion 43 is formed in a gently sloping state. Therefore, the air that gathers in the center of the width of the counter 42 tends to flow along the upper surface of the bulging portion 43 into the space below. In addition, 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 to the toes side. On the other hand, heated air has the tendency to rise. The air (warm air) that has been temperature-adjusted below the counter 42 flows directly above the counter 42 through the passage 43a formed by a cutout at the lower end of the bulging portion 43. The 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 remain on the underside of the counter 42. As a result, for those who wish to prevent the warm air from escaping all at once through the passage 43a, the counter 42 can minimize the escape of the rising warm air.

[0213] The air conditioning system for the room space 1 of this embodiment as described above can contribute not only to air conditioning the entire room space 1, but also to creating a good sleeping environment in the bed 10, one end 10a of which is positioned 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 through which the line of sight and air can pass in the vertical direction, so that a user P with his / her head positioned below it feels less oppressive than if the line of sight and air could not pass through. In addition, the plate material and bulging portion 43 constituting the counter 42 can effectively diffuse cool air whose temperature has been adjusted above the counter 42 and warm air whose temperature has been adjusted below the counter 42.

[0214] In this embodiment, the counter 42 is configured not to move up and down or adjust the angle, but is not limited to this, and may be provided to be movable in the up and down direction along the wall surface of the first wall portion 4a, or may be provided to be angle-adjustable with respect to the wall surface of the first wall portion 4a. Alternatively, the counter 42 may be rotated upward to be angle-adjustable in a state along the wall surface of the first wall portion 4a (in other words, a folded state).

[0215] Example 3-3 20, the room space 1 of this embodiment is provided with a third air diffusion means 45 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 cooling and heating device 12. The third air diffusion means 45 has a passage portion 45a that allows a line of sight and air to pass through in the vertical direction.

[0216] More specifically, the third air diffusion means 45 in this embodiment is a counter 45 provided to protrude from the wall surface of the first wall portion 4a. The counter 45 is provided at a height position above the upper surface of the bed 10. The bed 10 is also installed such that one end portion 10a is located below the counter 45. In other words, the counter 45 is located above the head of the user P.

[0217] 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 portion 4a. In this embodiment, two divided plates 45b are spaced apart in the width direction on the wall surface of the first wall portion 4a, and a gap 45a between these two divided plates 45b serves as a passage portion 45a through which lines of sight and air can pass in the vertical direction. The divided plate bodies 45b are formed of a 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.

[0218] In the example shown in FIG. 20(a), a passage portion 45a, which is a gap between two divided plate members 45b, can be opened and closed by two opening / closing members . Each opening / closing body 46 is attached to the lower surface of the respective divided plate body 45b via a movable mechanism 46a such as a slide rail. Moreover, each opening / closing body 46 is located lower than the lower surface of each divided plate body 45b. The distance between the two divided plates 45b is set shorter than the distance between the two opening / closing bodies 46 arranged side by side, so that the two opening / closing bodies 46 can reliably close the passage portion 45a, which is the gap between the two divided plates 45b.

[0219] In the example shown in FIG. 20(b), the passage portion 45a, which is the gap between the two divided plate members 45b, can be opened and closed by the two opening / closing members . Each opening / closing body 46 is attached to the top surface of a recess 45c formed in the lower surface of each divided plate body 45b via a movable mechanism 46a such as a slide rail. Also, each opening / closing body 46 is located above the lower surface of each divided plate body 45b. The distance between the two divided plates 45b is set shorter than the distance between the two opening / closing bodies 46 arranged side by side, so that the two opening / closing bodies 46 can reliably close the passage portion 45a, which is the gap between the two divided plates 45b.

[0220] In this embodiment, the opening / closing body 46 is configured to open and close the passage section 45a by opening and closing in the width direction of the counter 45 using a movable mechanism 46a, such as a long slide rail, that runs 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 / closing body 46 is not limited to that by the long slide rail 46a, but the opening / closing body 46 and the dividing plate body 45b may be rotatably connected via a hinge (i.e., a movable mechanism), and the opening / closing body 46 may be rotated in the vertical direction to open and close the passing section 45a. In addition, one corner of the opening / closing body 46 and one corner of the divided 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 passing portion 45a. Furthermore, in this embodiment, the opening / closing body 46 is in a state of being positioned below the divided plate body 45b, but this is not limited thereto, and it may be in a state of being positioned above the divided plate body 45b. In other words, it may be in a state in which it is turned upside down from the state shown in Figures 20(a) and (b).

[0221] 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.

[0222] 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. Moreover, the air near the radiant heating and cooling device 12 is temperature-adjusted by radiant heat from the radiant heating and cooling device 12. Then, 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 45, which serves as the third air diffusion means, is less likely to circulate directly below the counter 45 when the passage 45a is blocked by the opening / closing body 46. Furthermore, the air whose temperature is 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 passage 45a is blocked by the opening / closing body 46.

[0223] More specifically, cooled air has a tendency to descend. When passage 45a is closed by opening / closing body 46, air (cold air) that has been temperature-adjusted above counter 45 is less likely to flow 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 side of the user P's feet), and is therefore more likely to flow toward the user P's feet than toward the user P's head. For those who do 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 flow below the counter 45.

[0224] 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 wishes to prevent warm air from building up, the opening and closing body 46 is opened to open the passage portion 45 a, allowing the rising warm air to circulate above the counter 45 .

[0225] In other words, the counter 45, which is the third air diffusion means, can control the air flow in a plurality of patterns by appropriately opening and closing the opening / closing body 46, and therefore 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 contribute not only to air conditioning the entire room space 1, but also to creating a good sleeping environment in the bed 10, one end 10a of which is positioned close to the first wall portion 4a.

[0226] Furthermore, the counter 45 is configured so that the opening / closing body 46 can be opened and closed. Therefore, by opening the opening / closing body 46 and opening the passage portion 45a, the first wall portion 4a (or the upper wall 5) can be used as a headboard of the bed 10 and as a backrest for the user P.

[0227] [Example 3-4] 21, the room space 1 of this embodiment is provided with a fourth air diffusion means 47 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 cooling and heating device 12. The fourth air diffusion means 47 has a passage portion 47a that allows a line of sight and air to pass through in the vertical direction.

[0228] More specifically, the fourth air diffusion means 47 in this embodiment is a counter 47 provided to protrude from the wall surface of the first wall portion 4a. The counter 47 is provided at a height position above the upper surface of the bed 10. The bed 10 is also installed such that one end portion 10a is located below the counter 47. In other words, the counter 47 is located above the head of the user P.

[0229] As shown in FIG. 21, the counter 47 has a rectangular opening 47a formed in the center of the rectangular plate material that constitutes 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. In addition, the width of the counter 47 is set to be approximately equal to the width of the bed 10.

[0230] A passage portion 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 portion 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 fins 48a are attached to the frame in a state in which they can rotate around the axis of the rotation shaft, with the rotation shaft passing through the fins 48a along the length direction. In the example shown in Fig. 21, the fins 48a are rotated in the same direction so that the fins 48a come into contact with each other, thereby blocking the passage portion 47a, which is an opening. The fins 48a are rotated in the same direction so that the fins 48a are separated from each other, thereby opening the passage portion 47a, which is an opening.

[0231] 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.

[0232] 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. Moreover, the air near the radiant heating and cooling device 12 is temperature-adjusted by radiant heat from the radiant heating and cooling device 12. Then, 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 47, which is the fourth air diffusion means, is less likely to flow directly below the counter 47 when the passing portion 47a is blocked by the multiple fins 48a. Furthermore, the air whose temperature is adjusted at a position below the counter 47, which is the fourth air diffusion means, is less likely to flow directly above the counter 47 when the passing portion 47a is blocked by the multiple fins 48a.

[0233] More specifically, cooled air has a tendency to descend. When the passage 47a is blocked by the fins 48a, the air (cold air) that has been temperature-adjusted above the counter 47 is less likely to flow directly below the counter 47. Therefore, for people who dislike cold air hitting their face, blocking the passage 47a with the 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 toes side of the user P), and therefore is more likely to flow toward the toes of the user P than toward the head. For those who do not mind having cold air blown on their face, the fins 48a are rotated to open the passage 47a, allowing the descending cold air to flow below the counter 47.

[0234] 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 flow 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 wish to prevent warm air from building up, the fins 48a are rotated to open the passage portion 47a, allowing the rising warm air to flow above the counter 47.

[0235] In other words, the counter 47, which is the third air diffusion means, is capable of controlling the air flow in a plurality of patterns by appropriately opening and closing the multiple fins 48a of the opening / closing body 48, and therefore also functions as an airflow control means. Therefore, the air conditioning system for the room space 1 of this embodiment as described above can contribute not only to air conditioning the entire room space 1, but also 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 angles of the fins 48a are adjusted automatically or manually. When the operation is performed automatically, the louver device 48, which is an 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 the storage unit. Also, the control device is configured to control the drive unit according to the sensing result of a status detection sensor 21 provided in the room space 1.

[0236] According to this embodiment, the following excellent effects are obtained. That is, the counters 38, 39, 40, 41, 42, 45, 47 protruding forward from the wall surface of the wall portion 4 have passages 38a, 39a, 40a, 41a, 43a, 45a, 47a through which at least the line of sight and air can pass along the vertical direction of the counters 38, 39, 40, 41, 42, 45, 47, so that the line of sight can pass through in the vertical direction through the passages 38a, 39a, 40a, 41a, 43a, 45a, 47a, and air can also pass through in the vertical direction. This makes it difficult for the user P to feel a sense of oppression, so a sleeping environment with a minimal sense of oppression can be created. Furthermore, since the radiant heating and cooling device 12 is incorporated and supported in 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) temperature-adjusted by the radiant heating and cooling device 12 at a position above the counters 38, 39, 40, 41, 42, 45, 47 can be caused to descend into the space below through the passing portions 38a, 39a, 40a, 41a, 43a, 45a, 47a, or can be caused to descend from the protruding side end along the upper surface of the counters 38, 39, 40, 41, 42, 45, 47. 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 to prevent 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.

[0237] In addition, 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 are formed as the passages 38a, 45a, so that the line of sight can pass through in the vertical direction through the passages 38a, 45a, and air can also pass through in the vertical direction. This makes it difficult for the user P to feel a sense of oppression, so a sleeping environment with a minimal sense of oppression can be created. Furthermore, since the radiant heating and cooling device 12 is built into and supported by the wall portion 4 to which the counters 38, 45 are attached, objects located nearby can be heated or cooled by direct radiant heat from the radiant heating and cooling device 12, and temperature-controlled cold air above the counters 38, 45 and temperature-controlled warm air below the counters 38, 45 can be effectively diffused. This makes it possible to create a comfortable thermal environment in the room space 1 by utilizing the air whose temperature has been controlled by the radiant heating and cooling device 12.

[0238] In addition, 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 through. Furthermore, by appropriately opening and closing the passage section 45a using the opening / closing body 46, it is possible to control the flow of temperature-adjusted cold air at a position above the counter 45 and the flow of temperature-adjusted warm air at a position below the counter 45 in a plurality of patterns.

[0239] In addition, since the passing 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 a case in which the line of sight and air cannot 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 39, 42 and temperature-adjusted warm air at a position below the counters 39, 42, it is possible to create an air flow that is different from the case where, for example, an opening formed in the counter is used as the passage part, or the gap between spaced-apart boards is used as the passage part.

[0240] In addition, a notch 43a is formed in the lowest position of the bulge 43 formed in the widthwise center of the board that constitutes the counter 42, so that the air (cold air) that gathers in the widthwise center of the counter 42 can easily flow along the upper surface of the bulge 43 into the space below, and can easily descend through the notch 43a.

[0241] In addition, since the passing sections 40a, 41a, 47a are openings 40a, 41a, 47a that penetrate the counters 40, 41, 47 in the thickness direction, a user P using the space below the counters 40, 41, 47 is less likely to feel a sense of oppression compared to a case in which the line of sight and air cannot pass through. Furthermore, when creating a comfortable thermal environment in room space 1 by using temperature-adjusted cold air above counters 40, 41, 47 or temperature-adjusted warm air below 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.

[0242] In addition, the opening / closing body 48 that opens and closes the passage portion 47a is a louver device 48 that is provided in the passage portion 47a and has multiple fins 48a arranged in parallel that can rotate around the axis of a rotation shaft, so that the passage portion 45a can be blocked by the multiple fins 48a to prevent the line of sight from passing through. Furthermore, by appropriately opening and closing the passage portion 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.

[0243] <Fourth embodiment> Next, a fourth embodiment will be described with reference to the drawings. For convenience of explanation, elements common to the first to third embodiments are denoted by the same reference numerals, and explanations thereof will be omitted or simplified.

[0244] 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, a child's room, or a guest room in a house. The room space 1 is surrounded and formed 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 provided in the room space 1 configured as above.

[0245] [Example] The air conditioning system for the room space 1 in this embodiment will be described in more detail below. In addition, in each embodiment of the air conditioning system described below, it is assumed that the room space 1 has the above-mentioned configuration. In addition, common elements are given common reference numerals, and the description will be omitted or simplified as appropriate.

[0246] Example 4-1 22(a) and 22(b), the room space 1 of this embodiment is provided with a counter 49 that is disposed on the side of the first wall portion 4a, which is the support body, and serves as a fifth air diffusion means 49 that diffuses indoor air whose temperature has been adjusted by radiant heat from the radiant heating and cooling device 12. Furthermore, illuminance increasing means 50, 51 that increase the illuminance in the space below the counter 49 are provided on the underside of the counter 49.

[0247] 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 such 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.

[0248] 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, 51 are provided as illumination increasing means on the underside of such counter 49. The illumination devices 50, 51 are, for example, LED illumination devices, and are connected to a power supply unit (not shown) to receive power supply.

[0249] Furthermore, the lighting devices 50 and 51 are configured so that not only can they be turned on and off but also their illuminance can be adjusted by operating a controller (not shown). Furthermore, the controller is provided with a timer function, allowing the on / off of the lighting device 36 and adjustment of the luminance to be timer-controlled. The controller can be replaced by a computer such as a smartphone with a dedicated application downloaded onto it.

[0250] 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), the lighting device 51 is of an indirect lighting type and is not exposed on the underside of the counter 49. That is, a lighting storage section 52 formed in a substantially J-shape in a side cross-sectional view is provided at the end of the counter 49 in the protruding direction, and the lighting device 51 is stored in this lighting storage section 52 so that the light from the lighting device 51 does not directly enter the eyes of the user P standing below the 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 provided 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 lower surface of the counter 49, allowing light from the lighting device 51 to leak through this gap. The second plate 52b functions as a shielding plate to prevent light from directly reaching the user P who uses the lower space.

[0251] 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.

[0252] 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. Moreover, the air near the radiant heating and cooling device 12 has its temperature 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.

[0253] To explain in more detail, cooled air has a 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 direction side end (and width direction side end) of the counter 49, and therefore is more likely to flow toward the feet of the user P than toward the head.

[0254] 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 be used to 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, warm air that has been temperature-adjusted below the counter 49 tends to accumulate on the underside of the counter 49, thereby minimizing the escape of the rising warm air.

[0255] The air conditioning system for the room space 1 of this embodiment as described above can contribute not only to air conditioning the entire room space 1, but also to creating a good sleeping environment in the bed 10, one end 10a of which is positioned close to the first wall portion 4a. Furthermore, by providing lighting devices 50, 51 on the underside of counter 49, it is possible to adjust the illuminance in the space below counter 49. As a result, even if the space below counter 49 is in the shadow of counter 49 and becomes a low-illuminance space, the space below counter 49 can be brightened, which contributes to creating a good environment for getting up.

[0256] In this embodiment, the counter 49 is configured not to move up and down or adjust the angle, but is not limited to this, and may be provided to be movable in the up and down direction along the wall surface of the first wall portion 4a, or may be provided to be angle-adjustable with respect to the wall surface of the first wall portion 4a. Alternatively, the counter 49 may be rotated upward to be angle-adjustable in a state along the wall surface of the first wall portion 4a (in other words, a folded state).

[0257] 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.

[0258] 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 such that one end portion 10a is located below the counter 53. In other words, the counter 53 is located above the head of the user P.

[0259] 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 illuminance. The monitor 54 refers to a device that displays characters, figures, graphics, videos, etc., and is also called a display or a display device. Note that a tablet terminal or a television equipped with a display unit with similar functions may be used instead. Such a monitor 54 is connected to a power supply unit (not shown) and receives power. The monitor 54 is configured so that it can be turned on and off and the brightness of the screen can be adjusted by operating a controller (not shown). The monitor 54 may further include a speaker and a microphone.

[0260] The monitor 54 may be used not only to adjust the illuminance, but also to alleviate the sense of oppression caused by the counter 53 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 the 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 eliminating the sense of oppression. Also, an image of a natural environment such as a forest may be displayed on the screen. Furthermore, a camera may be installed on counter 53 to display the image of ceiling 3, or a camera may be actually installed on the roof and the view captured by the camera may be displayed on monitor 54.

[0261] A recess 53a is formed on the bottom surface of the counter 53, and a monitor 54 is housed in this recess 53a. When a tablet terminal, for example, is used as the monitor 54, the monitor 54 stored in the recess 53a may be held by a fastener such as a register mark so that the monitor 54 can be easily stored in and removed from the recess 53a.

[0262] 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.

[0263] 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. Moreover, the air near the radiant heating and cooling device 12 is temperature-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.

[0264] To explain in more detail, cooled air has a 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 direction side end (and width direction side end) of the counter 53, and therefore is more likely to flow toward the feet of the user P than toward the head.

[0265] 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 be used to 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 in the protruding direction.

[0266] The air conditioning system for the room space 1 of this embodiment as described above can contribute not only to air conditioning the entire room space 1, but also to creating a good sleeping environment in the bed 10, one end 10a of which is positioned close to the first wall portion 4a. In addition, 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. As a result, even if the space below the counter 53 becomes a low-illuminance space in the shadow of the counter 53, the space below the counter 53 can be brightened, which contributes to creating a good environment for getting up.

[0267] In this embodiment, the counter 53 is configured not to move up and down or adjust the angle, but is not limited to this, and may be provided to be movable in the up and down direction along the wall surface of the first wall portion 4a, or may be provided to be angle-adjustable with respect to the wall surface of the first wall portion 4a. Alternatively, the counter 53 may be rotated upward to be angle-adjustable so that it is in a state along the wall surface of the first wall portion 4a (in other words, in a folded state).

[0268] Example 4-3 24, the room space 1 of this embodiment is provided with a counter 55 as a seventh air diffusion means 55 that is disposed on the side of the first wall portion 4a, which is the support body, and that diffuses the air in the room whose temperature has been adjusted by radiant heat from the radiant heating and cooling device 12. 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.

[0269] 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 above the upper surface of the bed 10. The bed 10 is also installed such that one end portion 10a is located below the counter 55. In other words, the counter 55 is located above the head of the user P.

[0270] 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 the counter 55 as an illumination increasing means, with the mirror surface facing downward and tilted at an angle. Therefore, when the user P lies on the bed 10 with his / her head placed below the mirror 56, the light taken in from the outside of the space below the counter 55 reaches the user P's eyes. In other words, if the room space 1 is darkened when the user P goes to sleep, the light is less likely to reach the user P's eyes, but in the morning, the natural light that enters the room space 1 from outside can easily reach the user P's eyes. In addition, the user P can see his / her feet through the mirror 56 without raising his / her head.

[0271] The mirror 56 is a normal mirror, and is provided to span between the lower surface portion of the protruding direction end of the counter 55 and the first wall portion 4a. An insertion groove 55a is formed in the underside portion of the protruding end of the counter 55, and is elongated along the width direction of the counter 55. 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 the insertion groove 57a.

[0272] 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.

[0273] 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. Moreover, the air near the radiant heating and cooling device 12 has its temperature adjusted by radiant heat from the radiant heating and cooling device 12. Then, 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.

[0274] 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 direction side end (and width direction side end) of the counter 55, and therefore is more likely to flow toward the feet of the user P than toward the head.

[0275] 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 ends of the counter 55 and the mirror 56 in the width direction makes it even more difficult for the 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.

[0276] The air conditioning system for the room space 1 of this embodiment as described above can contribute not only to air conditioning the entire room space 1, but also to creating a good sleeping environment in the bed 10, one end 10a of which is positioned close to the first wall portion 4a. In addition, 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. As a result, even if the space below the counter 55 is in the shadow of the counter 55 and becomes a low-illuminance space, the space below the counter 55 can be brightened, which contributes to creating a good environment for getting up.

[0277] According to this embodiment, the following excellent effects are obtained. That is, since the radiant heating and cooling device 12 is built into and supported by 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 the air (cold air) whose temperature has been 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 direction side end along the upper surface of the counters 49, 53, and 55, and the air (warm air) whose temperature has been 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 allows a comfortable thermal environment to be created in the room space 1 by using the air whose temperature has been 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 for increasing the illuminance in the space below the counters 49, 53, 55, so that even if the space below the counters 49, 53, 55 becomes a low-illuminance space in the shadow of the counters 49, 53, 55, the space below the counters 49, 53, 55 can be brightened by the illuminance increasing means 50, 51, 54, 56. This makes it possible to create a sleeping environment (waking-up environment) that makes it easy to wake up in terms of illuminance.

[0278] In addition, since the illuminance 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 sleep environment that makes it easier to wake up in terms of illuminance.

[0279] Furthermore, counter 49 has lighting storage section 52 in which lighting device 51 is stored and for disposing 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, 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 enters the eyes.

[0280] In addition, the illuminance increasing means 54 is a monitor 54 for displaying images provided on the underside of the counter 53, and 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 counter 53 for the user P who uses the space below the counter 53.

[0281] In addition, the mirror 56, which is provided at an angle on the underside of the counter 55, is disposed so that the mirror surface faces diagonally downward on the opposite side to the wall portion 4, so that light taken in from outside the space below the counter 55 reaches the user P who uses the space below the counter 55. As a result, if the room space 1 is darkened at the time of going to sleep, light is less likely to reach the user P who uses the space below the counter 55, but in the morning, natural light that shines into the room space 1 from outside can easily reach the user P who uses the space below the counter 55, so it becomes easier to create a sleeping environment that makes it easier to wake up in terms of illuminance. Furthermore, since 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, the feeling of oppression caused by the counter 55 for the user P using the space below the counter 55 can be eliminated.
