Description

  The present invention relates to a solar heat collecting apparatus for buildings.

  Conventionally, a unit type building is known as a kind of building. A unit type building is a building constructed by connecting a plurality of building units to each other. The building unit has a rectangular parallelepiped frame having a plurality of columns and ceiling and floor beams connected to the columns, and the frame includes walls, floors, ceilings, etc. It is constructed by attaching various members.

  By the way, in recent years, various techniques for heating the inside of a building using the heat of sunlight have been proposed. For example, in Patent Document 1, in a unit type building, a heat collecting panel that collects heat by irradiating the roof portion with sunlight is installed, and the heat collected by the heat collecting panel is stored in the building. The technology which heats the inside using the heat storage material of this, and heat | fever stored in the heat storage material is disclosed. In this technique, a circulation path for circulating the heat medium between the heat collection panel and the heat storage material is provided, and the heat medium is circulated through the circulation path, whereby the heat of the heat collection panel is transferred to the heat storage material via the heat medium. It is transported and stored in the heat storage material. According to this, the room can be heated using the heat of sunlight even at night.

  Specifically, in the technique disclosed in Patent Document 1, in the same document 1, a heat storage chamber for storing a heat storage material is an underfloor space of a building unit, more specifically, each floor beam of the building unit (an underfloor space between floors). In some cases, it is provided in an inner space surrounded by ceiling beams. In this case, the heat in the heat storage material is released to warm the air in the chamber, and the heated air is used to heat the building. For example, the room is heated by releasing (heat radiation) the heat in the chamber from the surface of the chamber to the room or by blowing warm air in the chamber from the blowout port.

  By the way, in a unit type building, the underfloor space of the building unit is often used as an installation space for piping and wiring. Further, the under floor space of the building unit may be used as an article storage space. For this reason, when the chamber is installed in the under floor space of the building unit, there is a possibility that inconveniences such as restrictions on the routing of piping and wiring in the same space or the inability to use the same space as a storage space may occur.

  In addition, in a unit type building, not only the under floor space of the building unit but also the space behind the ceiling of the building unit, that is, the inner space surrounded by the ceiling beams of the building unit, is used for piping and wiring arrangement space, etc. There is. Therefore, such a problem may occur when the chamber is installed in the ceiling space of the building unit.

  On the other hand, if the chamber is installed on the floor of the building unit, the aesthetics in the building may be impaired.

  The present invention has been made in view of the above circumstances, and it is a main object of the present invention to provide a solar heat collecting apparatus for a building in which a heat storage chamber can be suitably installed without impairing the beauty of the building. It is what.

  In order to solve the above-mentioned problems, a solar heat collecting apparatus for a building according to a first aspect of the present invention includes a plurality of building units each having a plurality of pillars and ceiling and floor beams connected to the pillars. Applied to a unit-type building constituted by a heat collecting part that is provided on the outdoor side of the building and collects heat by receiving sunlight, and heat of sunlight collected by the heat collecting part A heat storage material for storing heat, a heat transport means for transporting the heat of the heat collecting part to the heat storage material via a heat medium, a heat storage chamber for accommodating the heat storage material therein, and the heat storage material Heat radiation means for releasing stored heat from the chamber to a room in the building, and the chamber is disposed in an inter-beam space between the large beams facing each other in a side-by-side adjacent building unit. It is characterized by being.

  In the solar heat collecting apparatus of the present invention, the heat of sunlight collected at the heat collecting section is transported to the heat storage material via the heat medium by the heat transport means, and stored in the heat storage material. The heat stored in the heat storage material is released from the chamber to the room in the building by the heat radiating means, and the room is warmed by the released heat. Thereby, the room can be heated using solar heat even in a time zone such as at night when sunlight is not irradiated.

  Further, according to the present invention, since the chambers are arranged in the inter-beam space between the large beams facing each other in the side-by-side adjacent building units, the chambers can be installed without impairing the aesthetic appearance in the building. . In this case, the chamber is different from the under floor space of the building unit (specifically, the inner space surrounded by the large beam of the floor of the building unit) or the back space (specifically, the inner space surrounded by the large beam of the ceiling of the building unit). Since it is installed at a place, the use of the chamber in other applications in the under floor space and the ceiling space of the building unit (for example, use as an installation space for piping and wiring) is not hindered. Therefore, in this case, the chamber can be preferably installed without deteriorating the aesthetics in the building.

  A solar heat collecting apparatus for a building according to a second aspect of the present invention includes, in the first aspect of the invention, an air outlet for blowing out air in the chamber to the room, and the heat radiating means is directed from the inside of the chamber toward the air outlet. A warm air supply means for causing the heat stored in the heat storage material to be released from the heat storage material and causing the released heat to be blown into the room as warm air from the outlet. Features.

  According to the present invention, the heat stored in the heat storage material is released from the heat storage material by causing the air flow from the inside of the chamber to the air discharge port by the warm air supply means, and the released heat is discharged from the air discharge port. It is blown into the room as warmer. In this case, heat release from the heat storage material can be promoted, and the released heat can be supplied to the room as warm air. Therefore, for example, the heating effect of the room can be enhanced as compared with a configuration in which the room is heated by releasing (radiating) heat stored in the heat storage material from the surface of the chamber.

  In the solar heat collecting apparatus for a building of the third invention, in the second invention, the air outlet is formed in the chamber, and the inside of the chamber faces the room located directly above or below the chamber. It is characterized by blowing out the air.

  According to the present invention, the air outlet is formed in the chamber itself, and warm air in the chamber is directly blown out from the air outlet to a room directly above or below the chamber. In this case, as compared with the configuration in which the warm air in the chamber is conveyed to the outlet through a ventilation member such as a ventilation duct, the configuration can be simplified because the ventilation member is unnecessary. In addition, since it is considered practically difficult to route the ventilation duct in the space between the beams, which is a narrow space, such a configuration can be said to be a practically preferable configuration for realizing the second invention.

  According to a fourth aspect of the present invention, there is provided a solar heat collecting apparatus for a building according to the third invention, wherein the chamber includes, as its internal space, a heat storage space portion provided with the heat storage material, and a blowout space portion communicating with the blowout port. The communication portion that communicates both the space portions in the chamber can be opened and closed in a closed state that blocks air flow between the space portions and an open state that permits the air flow. An opening / closing member is provided.

  According to the present invention, the open / close member is provided in the communication portion that communicates the heat storage space portion and the blow-out space portion in the chamber, and when the open / close member is in the closed state, Air flow is blocked. In this case, it is possible to prevent the heat naturally radiated from the heat storage material from flowing out from the heat storage space portion to the blowout space portion, and thus from flowing out from the blowout port to the room. Therefore, by closing the opening / closing member when storing heat in the heat storage material, it is possible to suppress wasteful consumption of the heat stored in the heat storage material, and to effectively use solar heat.

  By the way, even if an opening / closing member that opens and closes the air outlet is provided at the air outlet, and the air outlet is closed by the opening / closing member, the heat naturally radiated from the heat storage material is released from the air outlet to the room. Can be prevented. Here, the location where the heat storage material is installed in the chamber is determined by the position of the heat medium pipe that supplies the heat medium to the heat storage material, while the location where the air outlet is formed in the chamber is from the air outlet. It is determined by the room layout where warm air is blown out. Therefore, in the chamber, the location where the heat storage material is installed and the location where the air outlet is formed may be in a positional relationship apart from each other. In this case, the length of the chamber needs to be increased accordingly. However, when the length of the chamber is increased, the surface area of the chamber is increased accordingly, so that heat naturally radiated from the heat storage material is easily dissipated from the chamber surface. In this respect, according to the present invention, since the open / close member is closed, the heat naturally radiated from the heat storage material can be confined in a partial region (that is, the heat storage space) in the chamber. Even when the length is long, heat can be prevented from being dissipated from the chamber surface. Therefore, efficient heat storage becomes possible.

  According to a fifth aspect of the present invention, there is provided a solar heat collecting apparatus for a building according to the fourth aspect, wherein the warm air supply means is provided in the communication portion in the chamber, and the blowout space portion from the heat storage space portion through the communication portion. It is characterized by including a fan device for generating an air flow to.

  According to the present invention, the fan device is provided in the communication portion between the heat storage space portion and the blowout space portion in the chamber, and the air flow from the heat storage space portion to the blowout space portion by the fan device, and eventually to the blowout port. The air flow is directed to the direction. In this case, for example, compared with the case where a fan device is provided at the air outlet, heat radiation from the heat storage material can be promoted, and the heating effect of the room can be enhanced.

  In the solar heat collecting apparatus for a building of the sixth invention according to any one of the first to fifth inventions, the chamber is supported on each of the large beams facing each other in a neighboring building unit via a support member. It is characterized by that.

  According to a sixth aspect of the present invention, there is provided a solar heat collecting apparatus for a building, comprising: a lower floor unit and an upper floor unit that are vertically adjacent to each other as the building unit; The present invention is applied to a building in which a floor girder is vertically opposed to each other with a gap, and the chamber is arranged between adjacent floor girder in adjacent upper floor units and adjacent lower floor units in an inter-floor portion of the building. In the space between at least one of the facing ceiling beams, and the chamber is supported by each of the facing ceiling beams via the supporting member, and the supporting member is It has the mounting part mounted in the state inserted in the said clearance gap on each ceiling ceiling beam which opposes, It is characterized by the above-mentioned.

  The space between the beams on opposite ceilings in adjacent upper floor units and between the beams on opposite floors in adjacent lower floor units (first floor units) is located on the roof and under floor of the building. Insulation is often provided to ensure performance. On the other hand, since the heat insulation performance is not required so much in the inter-floor part of the building, the space between the beams in the upper floor units adjacent to each other and the space between the beam beams in the upper floor adjacent to each other between the ceiling beam beams in the adjacent lower floor units. Is rarely disposed. Therefore, in the present invention, paying attention to this point, the chamber is disposed in the inter-beam space in the floor portion of the building. In this case, when the chamber is installed in the space between the beams, it is easy to secure the installation space of the chamber, and the chamber can be more suitably installed.

  In addition, at the boundary between the lower floor unit and the upper floor unit adjacent to each other in the vertical direction, the ceiling beam of the lower floor unit and the floor beam of the upper floor unit may be opposed to each other vertically with a predetermined gap. Therefore, in the present invention, paying attention to the gap, the support member is placed on the opposing ceiling beam in the adjacent lower floor unit in a state where the support member is inserted into the gap, and the chamber is connected to each ceiling beam via the support member. To support. This makes it possible to favorably support the chamber in the inter-beam space in the interstory portion.

  A solar heat collecting apparatus for a building of an eighth invention is applied to a building including the lower floor unit and the upper floor unit which are vertically adjacent as the building unit in any of the first to seventh inventions, and the chamber is In the inter-floor portion of the building, the inter-beam space between the facing large beams in the adjacent upper floor unit is arranged in the inter-beam space between the facing large beams in the adjacent upper floor unit, instead of the space between the facing large beams in the adjacent lower floor unit. To do.

  By the way, in the inter-floor part of the unit type building, only the inter-floor space between the lower-floor unit and the upper-floor unit (specifically, the inner space surrounded by the ceiling beams of the lower-floor unit and the floor beams of the upper-floor unit) In addition, it may be considered that wiring and piping may be provided in the space between the beam beams between the adjacent upper floor beams in the adjacent upper floor unit and between the beam beams facing the ceiling in the adjacent lower floor unit. In this case, the wiring / piping is placed on the ceiling material of the lower floor portion provided below the space in the space between the beams (for example, the ceiling joint material connecting the ceiling surface materials of the adjacent lower floor units). It may be arranged in a state. Therefore, in the present invention, in view of this point, when installing the chamber in the inter-beam space in the inter-floor portion, the chamber is installed in the inter-beam space between the floor beams of the upper floor unit where wiring and piping are relatively rarely provided. It is arranged. In this case, the chamber can be suitably installed in the space between the beams in the interstory portion.

  A solar heat collecting apparatus for a building of a ninth invention is characterized in that, in any one of the first to eighth inventions, the room from which heat is released by the heat radiating means is a toilet, a dressing room or a bathroom. To do.

  In general, non-room spaces such as a toilet, a dressing room, and a bathroom are narrower than a living room space such as a living room and have a small volume (indoor volume). Therefore, in the present invention, in view of this point, the heat stored in the heat storage material is discharged to a toilet, a dressing room, or a bathroom for heating. In this case, in the above-described configuration in which the room is heated using the heat stored in the heat storage material, a sufficient heating effect can be obtained.

The building unit 20 is manufactured in advance in a manufacturing factory, and then transported to a construction site by a truck or the like. In the following, for convenience, the building unit 20 of the first floor portion 14 is sometimes referred to as a lower floor unit 20A, and the building unit 20 of the second floor portion 15 is referred to as an upper floor unit 20B.

  FIG. 2 shows a perspective view of the building unit 20. As shown in FIG. 2, the building unit 20 includes four columns 21 disposed at the four corners thereof, and four ceiling beams 22 and floor beams 23 that connect the upper end portion and the lower end portion of each column 21, respectively. And. A rectangular frame (frame) is formed by the pillars 21, the ceiling beams 22 and the floor beams 23. The column 21 is made of a square tube-shaped square steel. The ceiling girder 22 and the floor girder 23 are made of channel steel having a U-shaped cross section, and are installed so that their openings face each other.

  A plurality of small ceiling beams 25 are bridged between the large ceiling beams 22 on the long sides of the building unit 20 at predetermined intervals.

For example, the ceiling beam 25 is made of lip groove steel, and the floor beam 26 is made of square steel. The ceiling member 27 is supported by the ceiling beam 25 and the floor member 28 is supported by the floor beam 26.

  By the way, in the building 10 of this embodiment, the solar heat collection which collects the heat of sunlight by a heat collecting part, stores the collected heat in a heat storage material, and heats the building 10 using the stored heat. A device 40 is provided. Hereinafter, the solar heat collecting apparatus 40 will be described with reference to FIGS. 3 and 4. FIG. 3 is a schematic view showing an outline of the solar heat collecting apparatus 40, and FIG.

  As shown in FIG. 3, in the building 10, rooms 31 and 32 are provided on the first floor portion 14, and rooms 33 and 34 are provided on the second floor portion 15. Each of these rooms 31 to 34 is provided for each building unit 20, and the rooms 31 and 32 of the first floor portion 14 and the rooms 33 and 34 of the second floor portion 15 are partitioned vertically by the inter-floor portion 16. In the present embodiment, heating by the solar heat collecting device 40 is performed for the room 33 of the second floor portion 15 among these rooms 31 to 34. The room 33 is provided with a room temperature detection sensor 36 that detects the temperature of the room 33. This room temperature detection sensor 36 corresponds to a room temperature detection means.

  The solar heat collecting apparatus 40 includes a heat collecting panel 41 that collects heat (solar heat) when irradiated with sunlight, and a heat storage material 42 that stores heat collected by the heat collecting panel 41. The heat collection panel 41 is provided on the sunny roof 13 and has a heat collection plate made of a material having high thermal conductivity such as aluminum. In addition, the heat collection panel 41 does not necessarily need to be provided on the roof 13, and may be provided in other sunny places such as an outer wall. In this case, the heat collecting panel 41 corresponds to a heat collecting unit.

  The heat storage material 42 is made of, for example, a latent heat storage material. The heat storage material 42 is accommodated in a chamber 43 provided in the interstitial portion 16 of the building 10. The heat storage material 42 is provided with a heat storage amount detection sensor 37 (see FIG. 4) that detects the amount of heat stored in the heat storage material 42. This heat storage amount detection sensor 37 corresponds to a heat storage amount detection means. As the heat storage material 42, a sensible heat storage material made of a material having a large heat capacity such as concrete may be used instead of the latent heat storage material.

  The heat storage material 42 is connected to the heat collection panel 41 via a medium path. The medium path is a circulation path (circulation pipe) for circulating a heat medium such as water between the heat collection panel 41 and the heat storage material 42, and includes a heat medium pipe 44. An electric circulation pump 45 is provided in the middle of the heat medium pipe 44. The circulation pump 45 circulates the heat medium between the heat collection panel 41 and the heat storage material 42 through the heat medium pipe 44. The heat medium pipe 44 and the circulation pump 45 constitute a heat transport means.

  The heat medium circulating in the heat medium pipe 44 receives the heat collected by the panel 41 in the heat collection panel 41, and then transfers the received heat to the heat storage material 42. Thereby, the heat collected by the heat collection panel 41 is supplied (transported) to the heat storage material 42 via the heat medium and stored in the heat storage material 42.

  In addition, although illustration is abbreviate | omitted, each heat collection panel 41 and the heat storage material 42 are provided with the heat exchange part which performs heat exchange between the heat media which flow through the heat-medium piping 44, respectively. The heat medium receives heat from the panel 41 by exchanging heat with the panel 41 via the heat exchange unit of the heat collection panel 41. In addition, the heat medium exchanges heat with the heat storage material 42 via the heat exchange part of the heat storage material 42, thereby transferring the heat received from the heat collection panel 41 to the heat storage material 42.

  As shown in FIG. 4, the chamber 43 that houses the heat storage material 42 is formed in a rectangular parallelepiped shape (box shape) with a resin material having excellent heat insulation performance. The chamber 43 is provided with a partition member 49 that partitions the internal space (hereinafter referred to as “chamber inner space 47”) into a plurality of spaces. The partition member 49 is formed of a resin material having excellent heat insulation performance. The partition material 49 divides the chamber inner space 47 into a heat storage space portion 51 in which the heat storage material 42 is provided and a blowout space portion 52 that leads to an outlet 59 described later.

  The partition member 49 is formed with an opening 53 that allows the heat storage space 51 and the blowing space 52 to communicate with each other. Air can flow between the heat storage space 51 and the blowout space 52 through the opening 53. A fan device 54 is provided in the opening 53. The fan device 54 generates a flow of air from the heat storage space 51 to the blowing space 52 through the opening 53. The opening 53 corresponds to the communication portion, and the fan device 54 corresponds to the warm air supply means.

  The fan device 54 is provided with a shutter 56 as an opening / closing member that opens and closes the opening 53. The shutter 56 has a plurality of movable slats 57 arranged vertically. These slats 57 are rotatably provided and open and close the opening 53 by rotating. When each slat 57 (in other words, the shutter 56) is opened and the opening 53 is opened, air can flow between the heat storage space 51 and the blowing space 52 through the opening 53, and each slat. When 57 is closed and the opening 53 is closed, the air flow is blocked. Each slat 57 is driven to open and close by a slat drive unit 58 formed of an electric motor or the like. The slat drive part 58 is built in the fan device 54, for example.

  An air outlet 59 is formed in the upper plate portion 43 a provided on the upper side of the chamber inner space 47 in the chamber 43. The air outlet 59 is formed so as to open the air outlet space 52 toward the room 33 above (directly above) the air outlet space 52. Warm air in the chamber inner space 47 is blown out to the room 33 through the air outlet 59.

  Here, in the above configuration, when the fan device 54 is operated with the shutter 56 (each movable slat 57) opened, the chamber internal space 47 is connected from the heat storage space 51 to the air outlet 59 via the air outlet space 52. A flow of air is generated. In this case, the heat stored in the heat storage material 42 by the air flow is released from the heat storage material 42, and the released heat flows into the blowout space 52 through the opening 53, and then warm air from the blowout outlet 59. As shown in FIG. Thereby, the room 33 is heated (heated) by the blown-out warm air.

  On the other hand, when the operation of the fan device 54 is stopped and the shutter 56 is closed, the air flow between the heat storage space 51 and the blowing space 52 is blocked. Thereby, the blowing of warm air from the air outlet 59 is stopped, and the heating of the room 33 is stopped.

A ceiling surface material 27 made of gypsum board is attached to the lower surfaces of the field edges 66, and a ceiling connecting material 67 is attached between the ceiling surface materials 27 so as to connect the two ceiling surface materials 27. The ceiling connecting material 67 is made of a gypsum board having the same thickness as the ceiling surface material 27, and is fixed to the field edge 66 of both lower floor units 20A with screws or the like. Thereby, the ceiling surface which becomes substantially flush with each ceiling surface material 27 and the ceiling connecting material 67 is formed.

  The ceiling connecting member 67 is assembled between the ceiling surface members 27 of both lower floor units 20 </ b> A after each lower floor unit 20 </ b> A is installed when the building 10 is constructed. In addition, reference numeral 68 in FIG. 6 is a bracket for connecting the ceiling beam 22 and the ceiling beam 25.

  A support member 71 that supports the chamber 43 is provided across the ceiling beam 22 that faces each other in the adjacent lower floor unit 20A. The support members 71 are formed in a flat plate shape from a relatively high strength steel plate, and a plurality of support members 71 are arranged at predetermined intervals along the longitudinal direction of the ceiling beam 22 (installation direction of the chamber 43). The thickness of the supporting member 71 is equal to or greater than the (upper and lower) width of the gap 75 between the ceiling beam 22 of the lower floor unit 20A and the floor beam 23 of the upper floor unit 20B, which are vertically opposed to each other. It has been made smaller. The support member 71 is placed on the upper surface of each ceiling beam 22 with both ends in the spanning direction (in other words, the facing direction in which the ceiling beams 22 face each other) being inserted into the gap 75, respectively. In the installed state, it is fixed to the ceiling beam 22 with an adhesive tape or the like. A portion of the support member 71 that is inserted into the gap 75 and placed on the ceiling beam 22 corresponds to a placement portion.

  The fixing structure of the support member 71 is not necessarily limited to this, and the fixing structure is arbitrary, such as fixing to the ceiling beam 22 using a fastener such as a bolt. Further, the support member 71 may be merely placed on the ceiling beam 22 without being fixed to the ceiling beam 22. Further, it is not always necessary to arrange a plurality of support members 71, and only one support member 71 may be arranged.

  On the support member 71, the chamber 43 is placed in a state where it is placed. The chamber 43 is installed across the plurality of support members 71. In this case, the load of the chamber 43 is supported via the support member 71 by the ceiling ceiling beams 22 and by the lower floor units 20A. For this reason, the chamber 43 assumed to be a heavy object can be installed in a stable state in the inter-beam space 61.

  In such an installed state of the chamber 43, the upper surface portion of the chamber 43 (specifically, the upper plate portion 43 a) is in a position in contact with or close to the lower surface of the floor connecting material 63. Further, the chamber 43 has a lateral width (lateral width in the lateral direction) substantially equal to or smaller than the interval between the two floor beams 23 facing each other across the chamber 43.

  An opening 72 is formed in the floor connecting material 63 at a position corresponding to the air outlet 59 of the chamber 43. The chamber internal space 47 communicates with the room 33 through the opening 72 and the air outlet 59. The opening 72 is provided with a blow grill 73. The blow-out grill 73 has a plurality of slats 73a arranged side by side, and warm air in the chamber internal space 47 is blown into the room 33 through the slats 73a.

  Next, the electrical configuration of the solar heat collector 40 will be described with reference to FIG. FIG. 7 is a block diagram showing an electrical configuration of the solar heat collecting apparatus 40.

  As shown in FIG. 7, the building 10 is provided with a controller 60 as control means. The controller 60 includes a known microcomputer having a CPU and the like. A room temperature detection sensor 36 and a heat storage amount detection sensor 37 are connected to the controller 60, and detection results are sequentially input from these sensors 36 and 37.

  A circulation pump 45, a fan device 54, and a slat drive unit 58 are connected to the controller 60. The controller 60 controls the operations of these devices 45, 54, and 58 based on the detection results from the room temperature detection sensor 36 and the heat storage amount detection sensor 37.

  Next, the heating control process executed by the controller 60 will be described with reference to FIG. FIG. 8 is a flowchart showing the heating control process. Further, this process is repeatedly executed at a predetermined cycle.

  As shown in FIG. 8, first, in step S11, it is determined whether or not the current time is a predetermined heat storage time zone. Here, the predetermined heat storage time zone is set to a time zone in which sunlight is irradiated to the heat collection panel 41, that is, a time zone in which heat storage to the heat storage material 42 is possible. In the present embodiment, the heat storage time zone is set to, for example, 10:00 to 16:00. When the current time is a predetermined heat storage time zone, the process proceeds to step S17.

  In step S17, heat storage heat treatment is executed. In this process, the heat pump is circulated between the heat collection panel 41 and the heat storage material 42 by driving the circulation pump 45. Thereby, the heat collected by the heat collection panel 41 is supplied to the heat storage material 42 through the heat medium and stored in the heat storage material 42.

  In step S18, the heating process is stopped. In this process, the operation of the fan device 54 is stopped and the slat driving unit 58 is driven to close each movable slat 57 (shutter 56). Thereby, the blowing of warm air from the air outlet 59 is stopped, and the heating of the room 33 is stopped. That is, in the present control process, the room 33 is not heated while the heat storage material 42 is storing heat. Thereafter, this process is terminated.

  On the other hand, if the current time is not the predetermined heat storage time zone in step S11, the process proceeds to step S12. In step S12, it is determined whether or not the current time is a predetermined night time zone. In the present embodiment, the room 33 is heated using the heat stored in the heat storage material 42 in a predetermined night time zone. Here, the predetermined night time zone is set to, for example, 19:00 to 23:00. If the current time is not a predetermined night time zone, this process is terminated. On the other hand, if the current time is a predetermined night time zone, the process proceeds to step S13.

  In step S13, based on the detection result from the room temperature detection sensor 36, it is determined whether or not the temperature of the room 33 is equal to or lower than a predetermined temperature. Here, the predetermined temperature is set to a temperature at which it feels chilly enough to require heating, and is set to 15 ° C., for example. When the temperature of the room 33 is higher than the predetermined temperature, that is, when the heating of the room 33 is not necessary, this process is terminated. On the other hand, when the temperature of the room 33 is equal to or lower than the predetermined temperature, that is, when the room 33 needs to be heated, the process proceeds to step S14.

  In step S14, based on the detection result from the heat storage amount detection sensor 37, it is determined whether or not the amount of heat stored in the heat storage material 42 is equal to or greater than a predetermined amount. Here, the predetermined amount is set to a minimum amount of heat necessary for heating the room 33. When the amount of heat stored in the heat storage material 42 is less than a predetermined amount, this process is terminated. On the other hand, if the amount of heat stored in the heat storage material 42 is greater than or equal to a predetermined amount, the process proceeds to step S15.

  In step S15, a heating process is executed. In this process, each movable slat 57 (shutter 56) is opened by driving the slat drive portion 58, and the fan device 54 is operated. Thereby, warm air is blown out from the blower outlet 59 to the room 33, and the room 33 is heated.

  In step S16, the heat storage heat treatment is stopped. In this process, the circulation of the heat medium between the heat collection panel 41 and the heat storage material 42 is stopped by stopping the driving of the circulation pump 45. Thereby, it is possible to avoid a situation where the cold energy of the heat collecting panel 41 cooled at night is supplied to the heat storage material 42 and the heat storage material 42 is cooled. Thereafter, this process is terminated.

  Next, an installation example of the solar heat collecting device 40 with respect to the building 10 will be described in relation to an actual floor plan in the building 10. FIGS. 9A and 9B are floor plans showing the floor plan of the second floor portion 15 of the building 10.

  In the example shown in FIG. 9A, the toilet S <b> 1 provided in the second floor portion 15 of the building 10 is set in a room 33 as a heating target by the solar heat collecting device 40. The toilet S1 is formed so as to include a boundary portion between adjacent upper floor units 20B. The chamber 43 is disposed in the inter-beam space 61 between the large floor beams 23 of the upper floor unit 20B, and the air outlet 59 is opened on the floor surface of the toilet S1. In this case, the heat stored in the heat storage material 42 is blown out from the air outlet 59 as warm air to the toilet S1, and the toilet S1 is heated.

  Further, the toilet S1 is provided with a storage portion 81 for storing articles, and further, a pipe cover 82 is provided adjacent to the storage portion 81. The pipe cover 82 is provided so as to extend vertically along the side of the wall, and a heat medium pipe 44 (a part thereof) is disposed inside thereof. In this case, it is prevented that the heat medium piping 44 is exposed and the beauty of the toilet S1 is impaired.

  The heat medium pipe 44 is led downward from the inside of the pipe cover 82 and enters the underfloor space of the upper floor unit 20B (in other words, the interfloor space between the upper floor unit 20B and the lower floor unit 20A). The heat medium pipe 44 extends from the underfloor space of the upper floor unit 20 </ b> B to the inter-beam space 61 and is connected to the heat storage material 42 in the chamber 43. Although illustration is omitted, an insertion hole for passing the heat medium pipe 44 is formed in the web of the floor beam 23 of the upper floor unit 20B, and the heat medium pipe 44 passes through the insertion hole so that the space below the floor of the upper floor unit 20B. To the space 61 between the beams.

  On the other hand, in the example shown in FIG. 9B, the dressing room S <b> 2 on the second floor portion 15 is set in the room 33 as a heating target by the solar heat collecting device 40. The dressing room S2 is formed so as to include a boundary portion between adjacent upper floor units 20B. The chamber 43 is disposed in the inter-beam space 61 between the large floor beams 23 of the upper floor unit 20B, and the air outlet 59 is opened on the floor surface of the dressing room S2. In this case, the heat stored in the heat storage material 42 is blown out from the air outlet 59 as warm air to the dressing room S2, and the dressing room S2 is heated.

  The second floor portion 15 is provided with a storage portion 84 adjacent to the dressing room S2. The chamber 43 is disposed so as to straddle the storage portion 84 and the dressing room S <b> 2 in the inter-beam space 61, and the heat storage material 42 in the chamber 43 is disposed below the storage portion 84. A pipe cover 85 is provided inside the storage portion 84 so as to extend vertically along the wall, and a heat medium pipe 44 (a part thereof) is disposed on the inside thereof. The heat medium pipe 44 is led downward from the inside of the pipe cover 85 and enters under the floor of the upper floor unit 20 </ b> B, and further extends to the inter-beam space 61 and is connected to the heat storage material 42 in the chamber 43.

  Next, the construction procedure of the building 10 will be briefly described focusing on the installation work of the solar heat collecting device 40.

  At the time of construction, first, each lower floor unit 20 </ b> A constituting the first floor portion 14 is installed on the foundation 11. Then, the support members 71 are bridged on the opposing ceiling beams 22 in the adjacent lower floor units 20A, and the support members 71 are fixed to the ceiling beams 22 with an adhesive tape or the like.

  Next, each upper floor unit 20B constituting the second floor portion 15 is installed on the lower floor unit 20A. Thereafter, the chamber 43 is placed in the inter-beam space 61 between the large floor beams 23 facing each other in the adjacent upper floor unit 20 </ b> B and placed on the support member 71. Thereby, the chamber 43 is installed in the space 61 between beams. Thereafter, an operation such as connecting the heat medium pipe 44 to the heat storage material 42 in the chamber 43 is performed.

  Next, the floor connecting material 63 is attached between the floor materials 28 of the adjacent upper floor units 20B.

  Thereafter, the roof 13 is installed on the building body 12, and the heat collecting panel 41 is installed on the roof 13. Thereafter, an operation such as connecting the heat medium pipe 44 to the heat collecting panel 41 is performed.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  Since the chamber 43 is disposed in the inter-beam space 61 between the large floor beams 23 facing each other in the adjacent upper floor unit 20B, the chamber 43 can be installed without impairing the aesthetic appearance in the building 10. Further, in this case, the chamber 43 is located under the floor space of the building unit 20 (specifically, the inner space surrounded by the floor beam 23 of the building unit 20) or the ceiling space (specifically, the inner space surrounded by the ceiling beam 22 of the building unit). Since the chamber 43 is installed, the building unit 20 can be used for other purposes in the underfloor space or the ceiling space (for example, as a space for arranging piping or wiring). There is no hindrance. Therefore, in this case, the chamber 43 can be suitably installed without deteriorating the beauty in the building 10.

  The fan device 54 generates an air flow from the chamber 43 toward the air outlet 59, thereby releasing the heat stored in the heat storage material 42 from the heat storage material 42 and warming the released heat from the air outlet 59. I let it blow out into the room 33. In this case, heat release from the heat storage material 42 can be promoted, and the released heat can be supplied to the room 33 as warm air. Therefore, for example, the heating effect of the room 33 can be enhanced as compared with a configuration in which the heat in the chamber 43 is released (radiated) from the surface of the chamber 43 and the room 33 is heated.

  The air outlet 59 is formed in the upper plate portion 43 a of the chamber 43, and the warm air in the chamber 43 is blown out from the air outlet 59 to the room 33 immediately above the chamber 43. In this case, as compared with the configuration in which the warm air in the chamber 43 is conveyed to the air outlet 59 via the ventilation duct, the configuration can be simplified because the ventilation duct is unnecessary. Further, since it is considered that it is practically difficult to route the ventilation duct in the space 61 between the beams, which is a narrow space, such a configuration is a practically preferable configuration for blowing the warm air in the chamber 43 into the room 33 and heating it. I can say that.

  An opening 53 is formed in a partition member 49 that partitions the internal space of the chamber 43 into a heat storage space 51 and a blowout space 52. The opening 53 is provided with a shutter 56 that can be opened and closed in a closed state that blocks air flow between the space portions 51 and 52 and an open state that permits the air flow. In this case, by closing the shutter 56, it is possible to prevent heat naturally radiated from the heat storage material 42 from flowing out from the heat storage space 51 to the blowout space 52, and from the blowout port 59 to the room 33. It can be prevented from flowing out. Therefore, by closing the shutter 56 when storing heat in the heat storage material 42, it is possible to suppress wasteful consumption of the heat stored in the heat storage material 42 and to effectively use solar heat.

  In addition, an opening / closing member (for example, a shutter) that opens and closes the air outlet 59 is provided in the air outlet 59 and the air outlet 59 is closed by the opening / closing member to prevent heat from flowing from the air outlet 59 to the room 33. Is possible. However, in this embodiment, the chamber 43 is formed in a long shape because the location where the heat storage material 42 is installed in the chamber 43 and the location where the air outlet 59 is formed are separated from each other. Therefore, the surface area of the chamber 43 is relatively large. Therefore, the heat naturally radiated from the heat storage material 42 is easily dissipated from the surface of the chamber 43 to the outside. In this respect, according to the above-described configuration in which the shutter 56 is provided in the opening 53, the heat naturally radiated from the heat storage material 42 can be confined in the heat storage space 51 by keeping the shutter 56 closed. Even when the chamber 43 is formed in a long shape, it is possible to prevent heat from being dissipated from the surface of the chamber 43 in vain. Therefore, efficient heat storage becomes possible.

  A fan device 54 is provided in the opening 53, and the fan device 54 generates an air flow from the heat storage space 51 through the opening 53 to the blowing space 52, and thus an air flow toward the outlet 59. did. In this case, for example, compared with the case where the fan device 54 is provided at the air outlet 59, the heat radiation from the heat storage material 42 can be promoted, and the heating effect of the room 33 can be enhanced.

  A predetermined gap 75 is formed between the upper ceiling beam 22 of the lower floor unit 20 </ b> A and the upper floor beam 23 of the upper floor unit 20 </ b> B that are vertically opposed to each other. Therefore, in the present embodiment, the flat support member 71 is bridged over the opposing ceiling beams 22 in the adjacent lower floor unit 20 </ b> A while being inserted into the gap 75, and the chamber is placed on the bridged support member 71. 43 was installed. Thereby, the chamber 43 can be favorably supported in the inter-beam space 61 of the interstitial portion 16.

  Further, when constructing the building 10, the support member 71 is laid over the opposing ceiling beams 22 in the adjacent lower floor unit 20 </ b> A, and then the chamber 43 is placed between the beams only by placing the chamber 43 on the support member 71. Since it can be installed in the space 61, the installation work of the chamber 43 can be facilitated.

  In the inter-floor portion 16 of the building 10, the chamber 43 is not a space between beams between the facing ceiling beams 22 in the adjacent lower floor unit 20A, but a space 61 between beams between the facing floor beams 23 in the adjacent upper floor unit 20B. Arranged. The space between the beams of the interstitial portion 16 may be used as an installation space for piping and wiring. In that case, the piping and wiring are arranged in a state where they are placed on the ceiling connecting material 67 of the first floor portion 14. It is thought that it is done. In this regard, the chamber 43 is installed in the inter-beam space 61 between the large floor beams 23, so that the chamber 43 is suitable for the inter-beam space of the interstitial portion 16 while suppressing the interference of the chamber 43 with the piping and wiring. Can be installed.

  Heating was performed on the toilet S1 and the dressing room S2. The toilet S1 and the dressing room S2 are narrower than the living room space such as a living room and have a small volume (indoor volume). Therefore, even in the configuration of the present embodiment in which the room is heated using the heat stored in the heat storage material 42, a sufficient heating effect can be expected. The toilet S1 and the dressing room S2 are spaces where heat shock is likely to occur when entering and exiting the toilet S1, and the effect of making the heat shock difficult to occur can be expected by making these rooms S1 and S2 heating targets.

  When the temperature of the room 33 detected by the room temperature detection sensor 36 is equal to or lower than a predetermined temperature, the room 33 is heated. Thereby, since the heating of the room 33 is automatically started when the temperature of the room 33 decreases, the convenience can be improved.

  When the heat storage amount in the heat storage material 42 detected by the heat storage amount detection sensor 37 is equal to or greater than a predetermined amount, the room 33 is heated. As a result, even though the heat storage material 42 does not store heat sufficiently, the room 33 is heated, so that cold air is blown out from the air outlet 59 to the room 33 and the temperature of the room 33 decreases. It is possible to avoid inconveniences such as

  The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

  (1) In the above embodiment, in the inter-floor portion 16 of the building 10, the chamber 43 is disposed in the inter-beam space 61 between the floor beams 23 facing each other in the adjacent upper-floor unit 20B. The chamber 43 may be disposed in the space between beams between the ceiling large beams 22 facing each other in the adjacent lower floor unit 20A. In this case, the support member 71 is fixed to the upper surface portion of the chamber 43 by welding or the like, and the support member 71 is provided across the ceiling beams 22 facing each other in the adjacent lower floor unit 20A. It is conceivable to suspend and support the ceiling beam 22 via a support member 71. Further, in the arrangement configuration of the chamber 43, the air outlet is formed in the lower plate portion of the chamber 43, and the room 31 is heated by blowing warm air from the air outlet to the room 31 of the first floor portion 14. Conceivable.

  Further, the chamber 43 is disposed so as to straddle the inter-beam space 61 between the opposing large floor beams 23 in the adjacent upper floor unit 20B and the inter-beam space between the opposing ceiling large beams 22 in the adjacent lower floor unit 20A. May be. In this case, for example, the vertical height of the chamber 43 is set to be the same as the distance between the ceiling connecting member 67 of the first floor portion 14 and the floor connecting member 63 of the second floor portion 15, and the upper plate portion 43 a and the lower plate portion of the chamber 43 are set. It is conceivable to form an outlet in each. Then, since the warm air in the chamber 43 can be blown out from the respective outlets to the room 33 of the second-floor portion 15 and the room 31 of the first-floor portion 14, it is possible to heat the rooms 31 and 33. It becomes.

  Further, the chamber 43 is not necessarily arranged in the inter-beam space in the inter-floor portion of the building 10, and may be arranged in the inter-beam space in the under-floor portion or the ceiling back portion of the building 10. That is, the chamber 43 may be disposed in the space between the beam beams 23 adjacent to each other in the adjacent lower floor unit 20A, or in the space between beam beams occupying each other in the adjacent upper floor unit 20B. Good.

  (2) The air outlet 59 is not necessarily formed in the chamber 43. For example, it is conceivable to form the air outlet in the ceiling connecting member 67. In this case, it is considered that the air outlet and the chamber 43 are connected to each other through a ventilation duct, and the warm air in the chamber 43 is supplied to the air outlet through the air duct and is blown out to the room 31 of the first floor portion 14 from the air outlet. It is done.

  Further, an air outlet is formed in the ceiling surface material 27 of the room 32 in the first floor portion 14 and the floor surface material 28 in the room 34 of the second floor portion 15, and the air outlet and the chamber 43 are connected via a ventilation duct. Good. If it does so, the warm air in the chamber 43 can be supplied also to those rooms 32 and 34 which are not located right above the chamber 43 (just above) or just below (just below).

  (3) The support structure of the chamber 43 in the space 61 between beams is not necessarily limited to the structure of the said embodiment. For example, the floor connecting material 63 is fixed to the upper surface of the chamber 43 (specifically, the upper plate portion 43a), and the chamber 43 is integrated with the floor connecting material 63, and the floor connecting material 63 is adjacent to each other in the integrated state. It is conceivable that the floor unit 20B is bridged on each of the opposing floor beams 23 (specifically, on the floor joists 62). In this case, since the chamber 43 can be supported by being suspended from the floor beams 23 via the floor connecting material 63, the chamber 43 can be installed in a stable state even in such a case.

  Further, if the chamber 43 is integrated with the floor connecting material 63 at the unit manufacturing factory in advance, the installation of the chamber 43 can be performed only by attaching the floor connecting material 63 onto each floor beam 23 of the adjacent upper floor unit 20B at the construction site. Complete. In this case, the number of construction steps can be reduced.

  (4) In the above embodiment, the warm air in the chamber 43 is blown out and heated in the toilet S1 or the dressing room S2 in the building 10, but for example, warm air may be blown out and heated in the bathroom. Since the air volume of the bathroom is small like the toilet S1 and the dressing room S2, the solar heat collecting apparatus 40 that performs heating using the heat stored in the heat storage material 42 can also obtain a sufficient heating effect. is there. Moreover, not only non-room space, such as restroom S1 and dressing room S2, but warm air may be blown out and heated to room space, such as a living room or a bedroom.

  (5) In the above embodiment, the room 33 is heated by blowing out the heat stored in the heat storage material 42 as warm air from the chamber 43, but this may be changed. For example, the room 33 may be heated by radiating (heat radiation) heat stored in the heat storage material 42 from the surface of the chamber 43 toward the room 33. Specifically, by operating the fan device 54 to generate an air flow in the chamber 43, the heat stored in the heat storage material 42 is released from the heat storage material 42, and the released heat is supplied to the chamber 43. Heat is released from the surface to the room 33 for heating. Also in this case, it becomes possible to heat the room 33 using solar heat in a time zone such as at night when sunlight is not irradiated.

  In this configuration, the chamber 43 is not provided with the air outlet 59, and the chamber inner space is a closed space. The chamber 43 is preferably formed of a material having excellent heat dissipation performance such as metal.
