Further, a pocket space 12 sandwiched between the ceiling C and the floor F is provided inside the two intermediate partition portions 4 and 5, respectively.

  Rooms R1 to R4 are provided on each floor of the building 1, respectively. For example, one living room R1 is provided in the first floor portion of the building, for example, two living rooms R2 and R3 are provided in the second floor portion of the building, and one living room R4 is provided in the third floor portion of the building, for example. Is provided. In addition, a water room R5 such as a bathroom or a toilet is provided on the first floor portion of the building 1 adjacent to the living room R1.

  As shown in FIG. 3, the entire building air conditioning system includes a radiation panel device 20 as a device for air conditioning the building 1. As shown in FIGS. 1 and 3, the radiant panel device 20 includes a plurality of radiant panels 21 erected in the living rooms R1 to R4 on each floor, and a heat source unit 22 that supplies a heat medium to the radiant panels 21. Have.

  The radiation panel 21 has a vertical radiation surface 21a extending substantially in the vertical direction along the vertical direction of the living rooms R1 to R4, and is installed on the floor F of the living rooms R1 to R4 at the lower end portion thereof, and the upper end thereof. Part is supported by the ceiling C. In addition, if the radiation surface 21a is the structure which the radiation | emission surface 21a extends perpendicularly | vertically along the up-down direction of room R1-R4 and the upper end reaches near the ceiling C, the upper end necessarily reaches the ceiling C and the said The configuration may not be supported by the ceiling C.

  Although not shown, the radiant panel 21 includes a pipe through which the heat medium supplied from the heat source unit 22 is passed, and the heating or cooling function is performed by passing the heated or cooled heat medium through the pipe. The resulting configuration. The pipe is configured to be incorporated in the radiant panel 21 in, for example, a wave shape arrangement or a U-shape arrangement so that heat can be efficiently exchanged between the heat medium supplied from the heat source device 22 and the radiant panel 21. The

  The radiant panel 21 may have various shapes or configurations as long as it has a built-in pipe through which the heat medium supplied from the heat source unit 22 passes or has a hollow part through which the heat medium passes directly. Can do. For example, the radiation panel 21 has a louver shape in which a plurality of blade-like panels extending in the vertical direction are arranged at equal intervals in the horizontal direction, and is supplied from the heat source device 22 to the inside of these blade-like panels. It is possible to have a built-in pipe (or a hollow part) through which a heat medium passes.

  The heat source device 22 is disposed, for example, outside the building 1, and is connected to each radiation panel 21 provided in each room R <b> 1 to R <b> 4 via a heat medium supply pipe 23 and a heat medium recovery pipe 24. . The heat source unit 22 can be constituted by a heat pump, for example. When operating in the cooling mode, the heat source device 22 can cool the heat medium and supply the cooled heat medium to the radiation panel 21 via the supply pipe 23. Further, when operating in the heating mode, the heat source device 22 can heat the heat medium and supply the heated heat medium to the radiation panel 21 via the supply pipe 23.

The living rooms R1 to R4 can be heated.

  The radiation panel 21 can also be configured to serve as a partition wall that partitions two adjacent living rooms. For example, as shown in FIG. 1, in the second floor portion of the building 1, a moving passage is left between the living room R <b> 2 which is a dining room and the living room R <b> 3 which is a living room. In this state, the radiation panel 21 can be arranged as a partition wall. In this case, since the radiation panel 21 that also serves as the partition wall faces the respective living rooms R2 and R3, both the living rooms R2 and R3 can be cooled and heated by the single radiation panel 21. Therefore, it is possible to improve the layout of the entire building air conditioning system by omitting the installation space of the radiation panel 21 in each of the living rooms R2, R3, and to use the entire building air conditioning system without the need for providing separate partitions. 1 cost can be reduced.

  In addition, the radiation panel 21 is not limited to the arrangement that also serves as the partition wall of the two living rooms R2 and R3, and may be a position that can cool and heat the living rooms R2 and R3, for example, arranged near the walls of the living rooms R2 and R3. It can also be arranged at an arbitrary position.

Is provided. The floor-side vent 30 provided on the floor F on the first floor communicates with the under-floor space 10, and the floor-side vent 30 provided on the floor F on the second floor is an intermediate partition that partitions the first floor and the second floor. The floor side vent 30 provided in the floor F on the third floor communicates with the pocket space 12 of the intermediate partition 5 that partitions the second floor and the third floor.

  In addition, these floor side vents 30 can also be set as the structure which attached the louver (louver) as shown in FIG.

  Further, the ceilings C of the living rooms R1 to R4 where the radiation panel 21 is erected are respectively adjacent to the upper end portion of the radiation panel 21, that is, on the upper side along the radiation surface 21a. 31 is provided. The ceiling side vent 31 provided on the ceiling C on the first floor communicates with the pocket space 12 of the intermediate partition 4 that partitions the first floor and the second floor, and the ceiling side vent provided on the ceiling C on the second floor. 31 communicates with the pocket space 12 of the intermediate partition 5 that partitions the second floor and the third floor, and the ceiling-side vent 31 provided in the ceiling C on the third floor communicates with the ceiling space 11 of the building 1. .

  In addition, these ceiling side vents 31 can also be made into the structure which attached the louver (louver) similarly to the floor side vent hole 30. FIG.

  Further, a ceiling side vent 31 provided on the ceiling C on the first floor is a floor side vent 30 provided on the floor F on the second floor via the pocket space 12 of the intermediate partition 4 that partitions the first floor and the second floor. The ceiling-side vent 31 provided on the ceiling C on the second floor is connected to the floor-side ventilation provided on the floor F on the third floor via the pocket space 12 of the intermediate partition 5 that partitions the second and third floors. It communicates with the mouth 30.

  With such a configuration, the space between the underfloor space 10 and the back space 11 of the building 1 is a ceiling-side vent 31 provided in the ceiling C of each living room R1 to R4, and the floor F of each living room R1 to R4. Are communicated with each other through a floor space 12 provided in the floor side vent 30 and the intermediate partitions 4 and 5 provided in the interior.

  Here, by providing a pocket space 12 in the intermediate partitions 4 and 5 and having the floor-side vent 30 and the ceiling-side vent 31 communicate with each other via the pocket 12, The radiation panel 21 on the lower floor can be arranged so as to be displaced in the horizontal direction. This eliminates the need for alignment between the upper-floor floor-side vent 30 and the lower-floor ceiling-side vent 31, that is, alignment between the upper-floor radiation panel 21 and the lower-floor radiation panel 21. The layout of the panel 21 can be improved.

  The building 1 has a circulation path that connects the floor side vent 30 provided on the floor F on the first floor, which is the lowest floor, and the ceiling side vent 31 provided on the ceiling C, the third floor, which is the top floor. A direct duct 40 is provided. The direct duct 40 is formed in a cylindrical shape extending straight up and down, is connected to the ceiling C on the uppermost floor at one end thereof and communicates with the ceiling space 11, and is connected to the floor F on the lowermost floor at the other end. It communicates with the underfloor space 10. That is, the direct duct 40 is partitioned separately from the rooms R1 to R4 inside the heat insulation line of the building 1, and is separate from the communication path via the floor side vent 30, the ceiling side vent 31, and the pocket space 12 described above. The communication path directly communicates between the underfloor space 10 and the ceiling space 11 of the building 1 to form a circulation path between the underfloor space 10 and the ceiling space 11. The direct duct 40 may have a different shape such as a square tube. In addition, a commercially available duct member may be used, or a cylindrical space may be formed using a board material or the like as part of carpentry work or construction work.

  As described above, since the circulation path is configured by the direct duct 40 that directly communicates the underfloor space 10 and the ceiling space 11, air is efficiently circulated between the underfloor space 10 and the ceiling space 11. be able to.

  A circulation fan 41 is disposed in the underfloor space 10. The circulation fan 41 operates in the forward direction when the radiant panel device 20 is operating in the heating mode, forcing the air inside the direct duct 40 from the ceiling space 11 side toward the underfloor space 10 side. When the radiant panel device 20 is operating in the cooling mode, it is operated in the reverse direction to force air inside the direct duct 40 from the underfloor space 10 side toward the ceiling back space 11 side. Circulate.

  In the illustrated case, the circulation fan 41 is disposed in the underfloor space 10. However, if the air inside the direct duct 40 can be circulated, for example, an arbitrary position such as the interior of the ceiling space 11 or the direct duct 40 is provided. It can also be arranged.

  Next, the flow of air when the entire building of the building 1 is air-conditioned with one heat source unit 22 by the entire building air-conditioning system having such a configuration will be described.

  As shown in FIG. 1, when the radiant panel device 20 of the entire building air conditioning system is operated in the cooling mode, a cooled heat medium (cold water) is supplied from the heat source unit 22 to the radiant panels 21 installed in the respective rooms R1 to R4. The living rooms R1 to R4 in which the radiation panel 21 is provided are cooled by the heat absorbing action of the radiation panel 21.

  At this time, the cooling air cooled by the radiation surface 21 a of the radiant panel 21 generates a downward air flow along the radiation surface 21 a and passes through the floor-side vent 30 provided adjacent to the lower end of the radiant panel 21. Or it is led to the underfloor space 10. The cooling air guided to the pocket space 12 is supplied to the lower-floor room through the ceiling-side vent 31 provided in the ceiling C of the lower-floor room, and further descends along the radiation panel 21 of the lower-floor room. The floor side vent 30 provided in the floor F of the living room is further led to the pocket space 12 or the floor space 10 on the lower floor. Thus, all the cooling air cooled by the radiation panel 21 flows toward the lower floor through the floor side vent 30 or the ceiling side vent 31 and is guided to the underfloor space 10.

  The cooling air guided to the underfloor space 10 is guided to the ceiling space 11 along the direct duct 40 by the circulation fan 41, and from there to the room R4 again through the ceiling side vent 31 provided in the ceiling C on the uppermost floor. Supplied. Thereafter, the cooling air descends through the rooms R1 to R4 of each floor toward the underfloor space 10 through the same path as described above, thereby cooling the rooms R1 to R4.

  Thus, while cooling each room R1-R4 with the radiation panel 21 provided in each room R1-R4, the convection which the said cooling air produces | generates the cooling air which was cooled by the said radiation panel 21 and produced the downdraft It is possible to circulate (reflux) in the building 1 using exercise and forced circulation by the circulation fan 41 to cool all the rooms R1 to R4 comfortably without causing temperature unevenness in the vertical direction. In addition, such a whole building cooling can be performed by supplying a cooled heat medium from one heat source device 22 to a plurality of radiation panels 21.

  On the other hand, as shown in FIG. 2, when the radiation panel device 20 of the entire building air conditioning system is operated in the heating mode, the heat medium (hot water) heated from the heat source unit 22 to the radiation panels 21 installed in the respective rooms R1 to R4. Is supplied, and the living rooms R1 to R4 provided with the radiation panel 21 are heated by heat radiation from the radiation panel 21.

  At this time, the heated air heated by the radiation surface 21 a of the radiation panel 21 generates an upward air flow along the radiation surface 21 a, and the space 12 from the ceiling-side vent 31 provided adjacent to the upper end of the radiation panel 21. Or it is led to the ceiling space 11. The heated air guided to the pocket space 12 is supplied to the upper-floor room through the floor-side vent 30 provided in the floor F of the upper-floor room, and further rises along the radiation panel 21 of the upper-floor room. Then, the air is further guided from the ceiling-side vent 31 provided in the ceiling C of the living room to the pocket space 12 or the ceiling space 11 on the upper floor. Thus, all of the heated air heated by the radiation panel 21 flows toward the upper floor through the ceiling side vent 31 or the floor side vent 30 and is led to the ceiling space 11.

  The heated air led to the ceiling space 11 is led to the underfloor space 10 along the direct duct 40 by the circulation fan 41, and from there through the floor side vent 30 provided in the floor F on the lowermost floor, the living room R1 again. To be supplied. Thereafter, the heated air rises through the rooms R1 to R4 on each floor toward the ceiling space 11 through the same path as described above, so that these rooms R1 to R4 are heated.

  Thus, while heating each room R1-R4 with the radiation panel 21 provided in each room R1-R4, the convection which the said heating air produces | generates the heating air which was heated by the said radiation panel 21 and produced the updraft Circulation (recirculation) is performed in the building 1 using exercise and forced circulation by the circulation fan 41, and all the living rooms R1 to R4 can be comfortably heated without causing uneven temperature in the vertical direction. Moreover, such a whole building heating can be performed by supplying a heated heat medium from one heat source device 22 to the plurality of radiation panels 21.

  In the entire building air conditioning system of the present invention, the ceiling outlet 42 can be provided on the ceiling C of the room where the radiation panel 21 is not provided. In FIG. 1, FIG. 2, the case where the ceiling blowing part 42 is provided in the ceiling C of the water chamber R5 is shown. This ceiling blowing part 42 can be configured as an air supply fan, for example, and directs the air inside the pocket space 12 of the intermediate partition part 4 that constitutes the ceiling C of the water circulating room R5 toward the inside of the water circulating room R5. Can be blown out.

  By providing such a ceiling blow-out portion 42, for example, the partition that partitions the living room R1 and the water supply room R5 is not a radiant panel 21, but a normal wall, and the radiant panel 21 is provided in the water supply room R5. Even if it is not possible, the air that has been heated or cooled by the radiant panel 21 and entered the pocket space 12 can be blown from the ceiling blowing portion 42 into the water-circulating chamber R5 to cool and cool the water-circulating chamber R5. That is, the air heated or cooled by the radiation panel 21 can be supplied also to the room where the radiation panel 21 is not provided, such as the water chamber R5. Thereby, the comfort of the room in which the radiation panel 21 is not provided can be improved.

  In addition, the air supply fan 43 having the same configuration as that of the ceiling blow-out unit 42 can be provided on the ceiling C in a portion away from the radiation panel 21 of the living rooms R1 to R4 where the radiation panel 21 is provided. Thereby, the air heated or cooled by the radiation panel 21 can be supplied also to the part which is hard to be air-conditioned by the radiation panel 21 in the living rooms R1 to R4, thereby further reducing the temperature unevenness of the living rooms R1 to R4. be able to.

  The building 1 can also be provided with an air supply unit 50 that supplies outside air into the building 1 and an exhaust unit 51 that discharges the air inside the building 1 to the outside of the building 1. In the case shown in the figure, a case is shown in which an air supply unit 50 is provided at a position that partitions the underfloor space 10 of the outer wall 2. In this case, the air supply unit 50 can be configured as an outside air introduction fan, for example, and can supply outside air to the underfloor space 10. The air supply unit 50 is not limited to a configuration that supplies outside air to the underfloor space 10, and may be configured to supply outside air to the interior of the ceiling space 11 and the direct duct (circulation unit) 40.

  On the other hand, the exhaust part 51 can be configured as an exhaust duct provided with an exhaust fan 51a so as to be provided, for example, on the ceiling C of the water circulation room R5 on the first floor in FIGS. In this case, one end of the exhaust duct is opened to the water chamber R5, the other end is opened to the outside of the building 1, and an exhaust fan 51a is provided in the middle part of the exhaust duct.

  Moreover, the exhaust part 51 can also comprise the range hood 51b provided in living room R2 utilized as a dining kitchen on the 2nd floor in FIG. 1, FIG. 2, for example. In this case, the air in the room R2 can be exhausted to the outside by an exhaust fan (not shown) built in the range hood 51b.

  Furthermore, the exhaust part 51 can also be comprised with a simple exhaust fan so that it may be provided, for example in the part of the outer wall 2 of the 3rd floor in FIG. 1, FIG.

  Thus, by providing the air supply unit 50 and the exhaust unit 51 in the building 1, a part of the air circulating in the building 1 is supplied to the air circulating in the building 1 while supplying the outside air from the air supply unit 50 to the exhaust unit. The air can be exhausted from 51 to the outside of the building 1. Thereby, a part of the air circulating in the building 1 can be ventilated to reduce discomfort caused by the air that has been air-conditioned.

  This whole building air conditioning system is preferably applied to a building 1 which is a highly insulated house having a heat loss coefficient (Q value) of 1.9 to 0.6, for example. In this case, the underfloor space 10, the ceiling back space 11 and the direct duct (circulation path) 40 are preferably provided inside the heat insulation line of the building 1. In addition, the heat insulation line of the building 1 is a heat insulating material layer provided between the indoor and the outdoor of the building 1.

  By providing the whole building air-conditioning system in such a highly insulated house, the whole building can be efficiently air-conditioned by the heat source unit 22 having a smaller output.

  Further, when the building 1 provided with the entire building air conditioning system is a highly insulated house as described above, the heat transmissivity (K value) of the outer skin of the building 1, that is, the outer wall 2, is set to the direct duct (circulation path) 40. It is preferable to make it smaller than the heat transmissibility.

For example, in the present embodiment, as shown in FIG. 4, the direct duct 40 is a spiral duct 40a formed into a cylindrical body having a diameter of 300 mm by spirally winding a strip-shaped galvanized steel plate having a thickness of 0.5 mm. The glass wool 40b is wound as a heat insulating material around the outer peripheral surface with a thickness of 25 mm, and the thermal conductivity is 1.39 (W / m ² · K).

On the other hand, in the case of the building 1 having a heat loss coefficient of 0.6, as shown in FIG. 5A, the outer wall 2 is, for example, a urethane board 2b having a thickness of 140 mm on the indoor side of a plywood 2a having a thickness of 12 mm. And a 12 mm thick gypsum board 2c, a 50 mm thick urethane board 2d is affixed to the outdoor side of the plywood 2a, and a siding 2f is fixed to the outside of the urethane board 2d via a ventilator edge 2e. The configuration is made. Therefore, the heat flow rate of the outer wall (outer skin) 2 having such a configuration is 0.12 (W / m ² · K), which is about 1/12 of the heat reflux rate of the direct duct 40.

Further, in the case of the building 1 having a heat loss coefficient of 1.9, as shown in FIG. 5B, the outer wall 2 has a glass wool 2g of 100 mm thickness and a thickness of 12 mm on the indoor side of a plywood 2a having a thickness of 12 mm, for example. The siding 2f is fixed to the outdoor side of the plywood 2a through the ventilation trunk edge 2e. The heat flow rate of the outer wall (outer skin) 2 having such a configuration is 0.35 (W / m ² · K), which is about ¼ of the heat reflux rate of the direct duct 40.

  Thus, even if the heat of the air passing through the direct duct 40 escapes from the surface of the direct duct 40 by making the heat flow rate of the outer wall (outer skin) 2 of the building 1 smaller than the heat flow rate of the direct duct 40, The heat can be supplied to the inside of the building 1 and can be prevented from escaping to the outside of the building 1 through the outer wall 2 of the building 1, thereby further improving the cooling / heating efficiency of the building 1 by this whole-building air conditioning system.

  Note that, as described above, the heat flow rate of the outer wall 2 of the building 1 is preferably set to a value of ¼ to 1/12 of the heat flow rate of the direct duct 40. If it is smaller than the rate, it can be set to a value smaller than 1/12 of the heat flow rate of the direct duct 40.

  FIG. 6 is a modified example of the whole building air conditioning system shown in FIG. 1, and is an explanatory diagram schematically showing the case where the circulation path is configured by the blow-off portion 60 together with the air flow in the cooling mode, and FIG. It is explanatory drawing which shows schematically the whole building air conditioning system of the modification shown in FIG. 4 with the flow of the air at the time of heating mode.

  As shown in FIG. 6 and FIG. 7, the circulation path can also be configured by an atrium 60 of the building 1. That is, while opening a part of the two intermediate partition parts 4 and 5 and providing the blow-off part 60 in the building 1, the floor-side circulation port 61 is provided in the part facing the blow-off part 60 of the floor F on the lowest floor, The floor-side circulation port 61 allows the underfloor space 10 to communicate with the vent 60 and a ceiling-side circulation port 62 is provided in a portion facing the vent 60 of the ceiling C on the uppermost floor. It can be set as the structure which connected the space 11 to the blow-off part 60. FIG. In this case, the circulation fan 41 is preferably a ceiling fan (ceiling fan) that is attached to the ceiling C on the uppermost floor and disposed in the blow-off portion 60. In addition, this blow-off part 60 is good also as a staircase.

  Even in the configuration of such a modified example, the cooling air guided to the underfloor space 10 is guided to the blow-off portion 60 through the floor-side circulation port 61 during operation in the cooling mode, and the circulation fan 41 configured as a ceiling fan is used. The interior of the atrium 60 is moved toward the ceiling C on the uppermost floor and taken into the ceiling space 11 from the ceiling side circulation port 62 provided on the ceiling C. On the other hand, when operating in the heating mode, the ceiling space 11 The guided heated air is guided to the blow-through portion 60 through the ceiling-side circulation port 62, and the inside of the blow-off portion 60 is moved toward the floor F on the lowest floor by the circulation fan 41 configured as a ceiling fan. By taking in the underfloor space 10 from the floor-side circulation port 61 provided in the floor F, air can be circulated throughout the entire building.

  As described above, when the circulation path is configured by the blow-off portion 60, it is unnecessary to provide the direct duct 40, and the cost can be reduced and the space can be saved.

  It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

  For example, the entire building air conditioning system of the present invention is preferably applied to a highly insulated and airtight detached house, but also to a highly insulated and not airtight detached house, a maisonette type apartment house, and other buildings other than houses. Can be applied.

  Moreover, in the said embodiment, although the floor side vent 30 is provided only in the one side with respect to the radiation panel 21 of the floor F in which the radiation panel 21 is installed, both sides which pinched | interposed the radiation panel 21 of the floor F Each can also be provided with a floor-side vent 30. Similarly, in the above-described embodiment, the ceiling-side vent 31 is provided only on one side with respect to the radiation panel 21 of the ceiling C on which the radiation panel 21 is installed. Ceiling side vents 31 can also be provided on both sides sandwiched, respectively.

  Moreover, in the said embodiment, although the intermediate partition parts 4 and 5 are set as the structure which has the pocket space 12, respectively, these intermediate partition parts 4 and 5 are comprised only with a floor slab, for example. It is also possible to adopt a configuration that does not have the pocket space 12, such as those made.

  The whole-building air conditioning system of the present invention is not limited to the three-story building 1 shown in FIGS. 1 and 2, and can be applied to various buildings having an arbitrary level.

  INDUSTRIAL APPLICABILITY The present invention can be used when building a building such as a house equipped with a whole building air conditioning system.
