Description

  The present invention relates to an air conditioning structure used for a wooden building or a reinforced concrete building constructed as a general house.

  As heating means for general houses, heating appliances such as oil stove, gas stove, electric stove or kotatsu are used, and air conditioners or central heating systems with air conditioning functions are used. Floor heating systems with excellent heating effects are attracting attention, and the adoption of floor heating systems is increasing when building new buildings or renovating. Various types of air conditioning systems have also been developed that can cool and heat the entire house, including floor heating.

  FIG. 4 is a longitudinal sectional view showing a conventional building air conditioning system. In this air conditioning system, as shown in FIG. 4, an air conditioner 72 having a cooling / heating function and air purification is disposed under the floor 71 of the building 70, and the front end is open to the outside of the building 70. A duct 73, an air supply duct 75 that communicates with a branch device 74 for blowing conditioned air, and an air intake duct 78 that communicates with a branch device 77 for air suction disposed in the attic 76 are connected to the air conditioner 72. Yes. Further, an exhaust device 85 for exhausting indoor dirty air and moisture and an exhaust duct 84 connected to the exhaust device 85 are disposed between the first floor and the second floor.

  The outside air introduced from the duct 73 is temperature-adjusted and purified by the air conditioner 72, then supplied to the branching device 74 through the duct 75, and blown in each direction from a plurality of blower pipes 79 connected to the branching device 74. Is done. Since the conditioned air blown out from the blowout pipe 79 circulates through the underfloor 71, the air passage 83 and the attic 76 formed in the outer wall 80 and the partition wall 81, the entire building is air-conditioned to an appropriate temperature. Can do. In addition, dirty air, moisture, and the like in the room can be discharged to the outside by the exhaust duct 84 and the exhaust device 85 that open to each room.

  Since the air conditioner 72 also has a cooling and heating function, the building can be air-conditioned throughout the year. In winter, the conditioned air heated by the air conditioner 72 is circulated through the above-described route. Not only can the room be efficiently heated, but also the floor heating can be performed by the warm air blown from the blow-out pipe 79 to the lower floor 71.

  On the other hand, as a related art related to the present application, a first-floor room and a first-floor ceiling formed by a base portion, a wall portion, a first-floor floor and a first-floor ceiling floor provided in the wall portion in order from the bottom to the top. The building is composed of a roof made up of a roof and a ventilation device arranged in this building, and the radiator underfloor pan and the ventilation device arranged at a predetermined location in the building are connected to each other. In addition, there is a ventilation system having a heating action (see, for example, Patent Document 1).

JP 2003-42500 A

  In the case of the air conditioning system shown in FIG. 4, since the room is indirectly air-conditioned by conditioned air passing through the ventilation path 83 formed in the outer wall 80 or the partition wall 81, the efficiency is low and the energy consumption is also large. In addition, a large number of air conditioning pipes such as ducts 73, 75, and 78 must be connected to the air conditioner 72, and branching devices 72 and 77 must be disposed under the floor 71 and the attic 76, so that the structure is complicated. However, it requires a lot of piping materials for air conditioning, and it takes a lot of work and time for construction, and it may not be easily adopted for ordinary houses.

  In addition, since the air conditioner 72 is arranged under the floor 71, the operator has to sink into the floor 71 every time in the case of failure or maintenance as well as performing daily adjustment operations. Inconvenient. The ducts 73, 75, 78 and the branching devices 74, 77 are also not visible from the outside, and are easily placed out of reach, making it difficult to deal with troubles.

  Furthermore, since a space for arranging the air conditioner 72, the ducts 73, 75, 78, the branching devices 74, 77, and the like must be provided inside the under floor 71, the attic 76, and the partition wall 81, there is a sufficient space. It is difficult to adopt if it is not a building. Similarly, the ventilation system described in Patent Document 1 has a complicated structure and requires a lot of air-conditioning piping materials, and requires a lot of labor and time for construction.

  The problem to be solved by the present invention is that air conditioning piping materials are not required, cooling or floor heating can be performed efficiently, and daily operations and maintenance can be easily performed. It is to provide an air conditioning structure of a building.

  The building air-conditioning structure of the present invention includes a conditioned air generator arranged in the underfloor space for supplying warm air or cold air to the underfloor space of the building, the underfloor space in the wall constituting the building, and the A conditioned air passage provided in communication with the attic space of the building, a conditioned air outlet opened on the floor surface in the building in communication with the underfloor space or the conditioned air passage, and the conditioned air generation And an opening provided on the floor for operating the apparatus from the room.

  With such a configuration, the warm air or cold air supplied from the conditioned air generator to the underfloor space diffuses in the underfloor space and moves through the conditioned air path or attic space, and then on the floor in the building. Since it blows into the room from the established conditioned air outlet, the entire building can be efficiently heated or cooled while performing floor heating. The hot or cold air supplied from the conditioned air generator moves from the underfloor space through the conditioned air path and the attic space, so it does not require air conditioning piping materials such as ducts and branching equipment, and is provided on the floor surface. Since the conditioned air generating device can be operated from the room through the provided opening, daily operation and maintenance can be easily performed.

  The conditioned air generator is preferably an electric oil fan heater or an electric hot air fan heater for heating, and an electric or gas air conditioner is preferable for cooling. Comfortable air conditioning can be performed throughout the year by using an air conditioner with multiple functions.

  Here, if an air passage through which outside air can pass along each surface direction is provided on at least one of the outer wall and the roof constituting the building, the air layer present in the air passage exhibits a heat insulating function. Therefore, not only the air-conditioning efficiency in the building is improved, but also the retention of moisture is eliminated, and the dry state of the building can be maintained, so that the aging of the building can be suppressed.

  In this case, if an air supply / exhaust path that communicates the ventilation path provided on the outer wall and the room of the building is provided, the outside air passing through the ventilation path and the indoor air can be exchanged through the air supply / exhaust path. Therefore, the indoor air can be purified.

  On the other hand, if a heat insulating function is provided in the foundation body forming the bottom surface of the underfloor space, the temperature of the conditioned air supplied from the conditioned air generator to the underfloor space is prevented from dissipating to the ground through the foundation body. Therefore, it is effective for improving the air conditioning efficiency.

  In addition, if an exhaust device for exhausting the air in the attic space to the outside is provided, the air staying in the attic space is exhausted to the outside, whereby the inflow of the conditioned air from the underfloor space into the conditioned air path and The rise of the conditioned air in the conditioned air is promoted and the conditioned air circulates evenly in the building, so that the air conditioning state is made uniform and the air conditioning efficiency can be improved.

  The present invention has the following effects.

No piping material is required, and heating or cooling while performing floor heating can be performed efficiently, and daily operations and maintenance can be easily performed.

(2) If an air passage that allows outside air to pass along each surface direction is provided on at least one of the outer wall and the roof of the building, the heat insulation of the air layer existing in the air passage causes the inside of the building. Not only the air conditioning efficiency is improved, but also moisture retention is eliminated and the building can be kept in a dry state, so that deterioration of the building over time can be suppressed.

(3) If an air supply / exhaust path that communicates the ventilation path provided on the outer wall and the room of the building is provided, the outside air passing through the ventilation path and the indoor air may be exchanged through the air supply / exhaust path. Therefore, the indoor air can be purified.

(4) If a heat insulating function is provided in the foundation body forming the bottom surface of the underfloor space, the temperature of the conditioned air supplied from the conditioned air generator to the underfloor space is prevented from dissipating to the ground through the foundation body. Therefore, it is effective for improving the air conditioning efficiency.

(5) If an exhaust device for discharging the air in the attic space to the outside is provided, the inflow of conditioned air from the underfloor space into the conditioned air path by discharging the staying air in the attic space to the outside, and The rise of the conditioned air in the conditioned air is promoted and the conditioned air circulates evenly in the building, so that the air conditioning state is made uniform and the air conditioning efficiency can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a vertical sectional view showing an air conditioning structure of a building according to an embodiment of the present invention, FIG. 2 (A) is a partial plan view inside the building shown in FIG. 1, and FIG. 2 (B) is a building shown in FIG. FIG. 2C is a partial sectional view of the interior of the building shown in FIG. 1, and FIG. 3 is a partial sectional view of the foundation of the building shown in FIG.

  In the present embodiment, as shown in FIG. 1, an electric oil fan heater 3, which is one of the conditioned air generators, is arranged in the underfloor space 2 of the building 1, and is a wall that constitutes the building 1. A conditioned air passage 6 is provided in a certain outer wall 4 in communication with the underfloor space 2 and the attic space 5, and a plurality of conditioned air outlets 8 in communication with the underfloor space 2 are provided on the first floor surface 7 in the building 1. A conditioned air outlet 10 is also opened on the second floor 9 and communicated with the underfloor space 17 and the conditioned air passage 6 on the second floor 9. The oil fan heater 3 is operated from the room on the first floor 7. An opening 11 is provided for this purpose.

  Further, the outer wall 4 and the roof 12 constituting the building 1 are entirely provided with vent passages 13 and 14 through which the outside air can pass along the respective surface directions, and the vent passage 13 provided on the outer wall 4 and A plurality of air supply / exhaust passages 15 communicating with the room of the building 1 are provided. These air supply / exhaust passages 15 are respectively provided in a plurality of outer walls 4 that are opposed to each other, and are provided at a position near the first floor surface 7 and a position near the ceiling surface 20 of each outer wall 4. Moreover, the ventilation fan 16 as an exhaust apparatus for discharging | emitting the air in the attic space 5 to the outdoor is arrange | positioned in the gable | foot part of the outer wall.

  When the oil fan heater 3 is actuated to supply warm air to the underfloor space 2, the warm air diffuses in the underfloor space 2 and flows into the conditioned air passage 6, rises therein, and rises in the underfloor space 17 of the second floor portion. As well as moving to the attic space 5, the air is blown into the building 1 from the plurality of conditioned air outlets 8 opened on the first floor 7 and the conditioned air outlet 10 opened on the second floor 9. The entire room of the building 1 can be efficiently heated while performing floor heating of the floor surface 7 and the second floor surface 9.

  That is, the first floor surface 7 and the second floor surface 9 are warmed by the warm air passing through the underfloor spaces 2 and 17, so that the floor heating function is exhibited, and the room is directly warmed by the warm air blown from the conditioned air outlets 8 and 10. In addition, since the outer wall 4 is warmed by the warm air passing through the conditioned air passage 6 and the ceiling surface 20 is also warmed by the warm air flowing into the attic space 5, the entire room of the building 1 can be efficiently heated. Moreover, since the warm air supplied from the oil fan heater 3 moves from the underfloor space 2 through the conditioned air path 6, the second floor underfloor space 17 and the attic space 5, the duct used in the air conditioning system shown in FIG. It does not require piping materials for air conditioning such as branching equipment and can be used relatively easily in ordinary houses.

  As shown in FIG. 2, the oil fan heater 3 is arranged in an opening 11 provided on the first floor surface 7 with its upper portion exposed to the room, so that daily operation and maintenance are easy. As shown in FIG. 2 (A), the opening 11 is larger than the plane size of the oil fan heater 3, so that the first floor can be used even when the entire oil fan heater 3 is removed from the underfloor space 2. There is no need to break the floor surface 7 and the like, and the compatibility with the replacement work with a new conditioned air generator is also good.

  Since the opening 11 is covered by disposing the mounting-type storage furniture 19 on which the TV 18 or the like can be placed above the opening 11, the indoor aesthetic appearance is not impaired. . In addition, the conditioned air outlets 8 and 10 are each provided with a gallery 21 formed by arranging a plurality of blades 21a in an insulator shape as shown in FIG. , 17 prevents articles from falling.

  In the present embodiment, since the air passages 13 and 14 are provided in the outer wall 4 and the roof 12 constituting the building 1, the heat insulation of the air layer existing in the air passages 13 and 14 causes the inside of the building 1. Not only can the air-conditioning efficiency be improved, but dwelling of moisture does not occur and the building 1 can be maintained in a dry state, so that deterioration over time of the building 1 can be suppressed.

  In addition, since a plurality of air supply / exhaust passages 15 communicating the air passage 13 provided on the outer wall 4 and the room of the building 1 are provided, the outside air passing through the air passage 13 and the room through the air supply / exhaust passage 15 are provided. The room air can be exchanged, so that the air in the room can be purified.

  On the other hand, as shown in FIG. 3, the foundation body 22 that forms the bottom surface of the underfloor space 2 has a heat insulating function by sandwiching a heat insulating material 23 between two concrete layers 24. It is possible to prevent the temperature of the warm air supplied from 3 to the underfloor space 2 from being dissipated to the ground 25 or the like via the foundation body 22, which is effective in improving the air conditioning efficiency.

  Moreover, if the ventilation fan 16 of the gable part of the building 1 is operated, the air staying in the attic space 5 is discharged to the outside of the room, whereby the inflow of warm air from the underfloor space 2 into the conditioned air passage 6 and the conditioned air. Since the warm air rise in the road 6 is promoted and the warm air circulates in the building 1 evenly, the air conditioning state is made uniform, and the air conditioning efficiency can be improved. When the temperature is low, relatively low-temperature air in the underfloor space 2 may flow into the conditioned air path 6 and the heating effect may be reduced. Therefore, the ventilation fan 16 is not operated continuously, but is operated intermittently. It is desirable to make it.

  In this embodiment, since the electric oil fan heater 3 is used as the conditioned air generating device arranged in the underfloor space 2, the entire room can be efficiently heated while performing floor heating in the building 1. However, since the present invention is not limited to this embodiment, if an electric or gas cooling air conditioner or the like is installed in place of the oil fan heater 3, the room can be efficiently cooled. If an air conditioner with a function is installed, comfortable air conditioning can be performed throughout the year.

  In addition, when the temperature rises in summer or the like, the temperature in the attic space 5 also rises and the cooling efficiency may decrease. Therefore, a temperature sensor (not shown) is arranged in the attic space 5 and the inside of the attic space 5 When the temperature exceeds a certain temperature, it is desirable to provide a system in which the temperature sensor detects it and the ventilation fan 16 starts automatically.

  In addition, in the season when it is not necessary to perform air conditioning such as in spring or autumn, or in the rainy season, a blower is installed in place of the conditioned air generator (oil fan heater) 3 so that only air is blown into the underfloor space 2. It is also possible to do this, thereby ensuring ventilation of the underfloor spaces 2 and 17, the conditioned air passage 6 and the attic space 5, and also exhibiting a dehumidifying function, thereby suppressing the aging deterioration of the building promoted by moisture can do.

  The present invention can be widely used as an air conditioning system for general houses.
