  The house 10 includes a foundation 11, a floor 14 provided on the foundation 11, a first floor space 17 constituting a lower floor space, a second floor space 18 and a hut back space 19 constituting an upper floor space. The roof 13 is configured in the form of a mountain-shaped gable or a ridge building, and the roof space 19 is provided below the roof 13. This attic space 19 communicates with the second-floor space 18. Further, the first floor space 17 and the second floor space 18 may be partitioned into a plurality of rooms by partition walls (not shown).

  The foundation 11 of the house 10 (in this embodiment, a solid foundation) is not provided with a ventilation port, and a heat insulating material 15 such as an extruded polystyrene foam is attached to the outer side surface thereof, and the heat insulating material 15 is The side surface of the foundation 11 is covered to a depth of about 1 m in the ground so that the foundation 11 is not affected by the horizontal heat near the ground surface. Moreover, since a heat insulating material is not installed between the foundation 11 and the floor 14, as will be described later, the heat of heat storage can be conducted through the foundation to warm the house 10. The house 10 may be a building such as a detached house, an apartment, a building, or a condominium.

  Further, the house 10 includes a heat storage system 30 and a cold storage system 60 in order to cool and heat the floor space 16 such as the first floor space 17 and the second floor space 18.

The heat storage system 30 is installed in the upper part of the house 10, and the ventilation of the roof 13 (the south side roof surface 13 </ b> A and the north side roof surface 13 </ b> B) including the ventilation layer 31 through which air flows and the ventilation of the south side roof surface 13 </ b> A as the heat collector 40. A first duct 33a that communicates the layer 31, a first fan 34 as a heat storage gas supply means , a second duct 33b that communicates the first fan 34 and the heat storage exchange layer 25, and heat storage installed in the ground The exchange duct 25, the heat storage layer 21, the third duct 36 communicating with the duct switching machine 37 installed in the first floor space 17 from the heat storage exchange layer 25, and the duct switching machine 37 communicating with the first floor space 17, The indoor warm air duct 38 that discharges air to the first floor space 17 and the exhaust warm air duct 39 that communicates from the duct switching machine 37 to the outside of the house 10 are configured.

  In the first duct 33a, the duct inlet 32 at the upstream end is opened in the ventilation layer 31 of the south roof surface 13A, and the first fan 34 operates, so that air is supplied from the duct inlet 32 to the first duct 33a. Then, the air is blown as it is into the second duct 33b connected to the first duct 33a.

  The other end of the second duct 33 b is connected to the heat storage exchange layer 25 embedded in the lower surface of the foundation 11 of the house 10. The air that has flowed into the second duct 33 b flows into the steel pipe 22 installed in the heat storage exchange layer 25.

  Moreover, in order to discharge | emit the said air which flowed into the heat storage exchange layer 25 from the 2nd duct 33b, the 3rd duct 36 is installed toward the heat storage exchange layer 25 and toward the ground in the vertical direction. The 3rd duct 36 connects the duct switching machine 37 which switches ventilation to two directions at the front-end | tip part on the ground side.

  The duct switching machine 37 is connected at one end to an indoor warm air duct 38 for blowing air into the house 10 and an exhaust warm air duct 39 for discharging the air to the outdoors. The duct switching machine 37 is switched automatically or manually so that the air blown from the duct switching machine 37 flows into the indoor warm air duct 38 or the exhaust warm air duct 39. The indoor warm air duct 38 blows warm air into the house 10 to heat the first floor space 17 and the second floor space 18. Since the warm air rises from the bottom to the top, the indoor warm air duct 38 is preferably installed in the first floor space 17.

Further, the first duct 33a, the second duct 33b, the third duct 36, the indoor warm air duct 38 and the exhaust warm air duct 39, which constitute the heat storage gas supply means , warm air flows inside, so that the Cover with heat insulation to prevent heat dissipation.

  The heat storage exchange layer 25 includes a steel pipe 22, mountain sand 23, and crushed stone 24, and is installed between the lower surface of the foundation 11 of the house 10 and the upper surface of the heat storage layer 21 in parallel with the bottom surface of the house 10. The range of the heat storage exchange layer 25 may be an area equal to or smaller than that of the foundation 11, and the efficiency of heat exchange increases as the ground contact area with the heat storage layer 21 increases.

  First, the heat storage exchange layer 25 is formed by laying crushed stones 24 on the upper surface of the heat storage layer 21 to form a layer, and the steel pipes 22 meander at equal intervals on the upper side of the crushed stone layer. By meandering the steel pipe 22, the total length of the steel pipe 22 in the heat storage exchange layer 25 is made as long as possible, the surface area of the steel pipe 22 is increased, and the efficiency of heat exchange is improved. The gap between the steel pipes 22 is filled with mountain sand 23 to fix the steel pipes 22 and to serve as a heat exchange medium. The steel pipe 22 is preferably made of a metal having good thermal conductivity (carbon steel, alloy steel, stainless steel, etc.). And the heat storage exchange layer 25 is comprised by spreading the crushed stone 24 again on the upper surface of the mountain sand 23, and making a layer.

The heat storage layer 21 can use the general ground for constructing the house 10 as it is. If it is a ground soil or the like on which a general house or building can be constructed, special processing or installation of equipment is unnecessary, and the soil can be used as the heat storage layer 21 as it is. The range of the heat storage layer 21 is equivalent to the area covered with the foundation 11 in the horizontal direction, and the depth is preferably about 5 m, but is not particularly limited. For example, when the floor area of the house 10 is 70 square meters (m ² ) and the depth of the heat storage layer 21 is 5 m, the volume of the heat storage layer is 350 cubic meters (m ³ ).

  In addition, although the heat of the thermal storage layer 21 conducts the thermal storage exchange layer 25 and the foundation 11 and warms the air in the house 10, if the heating of the house due to the conduction is not taken into consideration, the house 10 is directly above the thermal storage layer 21. Alternatively, there may be a facility such as a parking lot, a field (including a plastic house), or an open space instead.

The cold storage system 60 is installed outdoors as a cold storage gas supply means , and is used to discharge the air from the ground, a cold storage duct inlet 62 for blowing air, a cold storage fan 64, a cold storage first duct 63, and the like. Cool storage second duct 66, cool storage duct switching machine 67, indoor cool air duct 68 for blowing air into house 10, exhaust cool storage duct 69 for discharging the air to the outdoors, and underground cool storage exchange layer 75 The cold storage layer 71 is used.

  On the outdoor ground, a cold storage duct inlet 62 for blowing air is installed, and in the vicinity of the cold storage duct inlet 62, a cold storage fan 64 is installed. When the cool storage fan 64 operates, air is blown from the cool storage duct inlet 62 to the cool storage first duct 63. The other end of the cold storage first duct 63 is connected to the cold storage exchange layer 75 in the ground, and blows the air from the first cold storage duct 63 to the cold storage steel pipe 72 installed in the cold storage exchange layer 75.

  Moreover, in order to discharge | emit the said air which flowed into the cool storage exchange layer 75 from the cool storage 1st duct 63, the cool storage 2nd duct 66 is installed in the vertical direction toward the ground in connection with the cool storage exchange layer 75. . The cool storage second duct 66 is connected to the tip of the ground side with a cool storage duct switching machine 67 for switching the air flow in two directions.

  The cool storage duct switching machine 67 is connected at one end to an indoor cool air duct 68 for blowing air into the house 10 and an exhaust cool storage duct 69 for discharging the air to the outdoors. The cool storage duct switching machine 67 is switched automatically or manually so that the air blown from the cool storage second duct 66 flows to the indoor cool air duct 68 or the exhaust cool storage duct 69. The indoor cool air duct 68 blows cool air into the house 10 to cool the first floor space 17 and the second floor space 18. Since the cool air descends from the top to the bottom, the indoor cool air duct 68 is preferably installed in the second floor space 18.

  Moreover, since cold air | flow flows through the cool storage 1st duct 63, the cool storage 2nd duct 66, the indoor cool air duct 68, and the exhaust cool storage duct 69, the heat insulating material is covered in order to prevent the heat radiation from air. .

  The cold storage exchange layer 75 includes a cold storage steel pipe 72, a cold storage mountain sand 73, and a cold storage crushed stone 74. The cold storage heat insulating material 76 is spread in parallel with the ground at a position of about 50 cm in the ground, and the cold storage heat insulating material 76 is provided. It is installed by being bent by about 1 m below the edge, and installed between the lower surface of the cold storage heat insulating material 76 and the upper surface of the cold storage layer 61.

  First, the cold storage exchange layer 75 is formed by laying cold storage crushed stones 74 on the upper surface of the cold storage layer 61 to form a layer, and the cold storage steel pipe 72 is folded and meandered on the crushed stone layer and arranged at equal intervals. By causing the cold storage steel pipe 72 to meander, the total length of the cold storage steel pipe 72 in the cold storage exchange layer 75 is made as long as possible, the surface area of the cold storage steel pipe 72 is increased, and the efficiency of heat exchange is improved. The gap between the cold storage steel pipes 72 is filled and fixed with cold storage mountain sand 73, and used as a heat exchange medium. It is preferable to use a metal (carbon steel, alloy steel, stainless steel, etc.) having good thermal conductivity for the cold storage steel pipe 72. In addition, on the upper surface of the cold storage exchange layer 75, a cold storage heat insulating material 76 such as an extruded polystyrene foam is installed. The cold storage heat insulating material 76 bends the end portion and covers up to about 90 cm in the ground. Care is taken not to be affected by the heat on the ground.

  The cold storage layer 71 uses a general ground as it is. If the soil such as a common house or building can be constructed on the ground, special processing or installation of equipment is unnecessary, and the soil can be used as the livestock cooling layer 71 as it is. Moreover, since it does not visit the presence or absence of a building on the ground, you may use underground, such as a parking lot, a park, and an open space. In order to keep cool air, a shaded place on the north side of the building is preferable. The area of the cold storage layer 71 is equal to or less than that of the cold storage exchange layer 75 and the depth is preferably about 5 m, but is not particularly limited.

[Effects of heat storage layer and cold storage layer]
The heat retention effect of the heat storage layer 21 and the cold storage layer 71 will be described with reference to FIGS. 3 and 4. FIG. 3 shows the annual temperature change of the heat storage layer. FIG. 4 shows the annual temperature change of the cold storage layer. The line in the figure shows the annual temperature change at each depth of 0.1 m to 5.0 m in the ground. In addition, the temperature of the solid heat storage layer 21 and the heat storage layer 71 shown in FIG. 3 and FIG. 4 shows the average value of the measured temperature at each depth of 0 m to 5.0 m in the ground.

  The underground is known to maintain a nearly constant temperature / humidity throughout the year, with less temperature change and deeper underground, generally in place of refrigerators and storages. Is used. For example, as shown in FIGS. 3 and 4, the underground temperature in Tokyo is greatly affected by the temperature of the ground at 0.1 m underground, up to about 3 degrees in February and up to about 29 degrees in August. Temperature change is severe. However, at 5 meters underground, the temperature change is less throughout the year, about 17 degrees in February and about 15 degrees in July.

  Based on the above results, the applicant of the present application has found that the ground temperature is sufficiently lower than the ground temperature even in the hottest summer in the year, and the coldest winter in the year is the ground. We paid attention to the fact that the temperature is sufficiently warm compared to the ground temperature, the phenomenon of reversal of season and temperature occurs for about half a year, and that the deeper the depth, the better the heat retention. Utilizing such underground temperature characteristics, the heat of the warm season is stored in the underground heat storage layer, and the heat of the heat storage layer is used to heat and heat the air in the cold season when the outside air is about six months later. And cold air in the cold season is stored in the cold storage layer in the ground, and in the season when the outside air is hot after about six months, the cold air in the cold storage layer is used to cool the air and use it for cooling Realized that.

  As a result of the experiment, as shown in FIG. 3, the underground temperature from December to March in winter is 5 degrees or less when the underground depth is 0.1 m, and about 17 degrees when the underground depth is 5.0 m. However, when the heat storage of the present invention is performed on the heat storage layer after early autumn, the temperature of the heat storage layer in December to March is about 20 degrees, which shows the effect of the heat storage.

  As shown in FIG. 4, the underground temperature from June to September in the summer is about 23 to 29 degrees Celsius at an underground depth of 0.1 m, and about 15 degrees Celsius at an underground depth of 5.0 m. However, when the cold storage of the present invention is performed on the heat storage layer from early winter, the temperature of the cold storage layer in June to September is about 13 to 17 degrees, which shows the effect of the cold storage.

In this way, the heat and cold of half a year ago are stored in the ground, that is, heat and cold for other seasons with different temperatures are actively stored in the ground, and the heat and cold stored in the ground are stored in the house. By using it for air conditioning, an efficient and economical air conditioning system can be constructed [heat storage in the heat storage layer].
A method of heat storage and room heating will be described with reference to FIG. Since the heat storage period takes about two months to store heat in the heat storage layer on the soil, it is calculated backwards from the end of November when heating of the house is necessary, and early autumn to early spring (late September to late March next year) It is suitable to carry out to. Around mid-summer July to August, when heat is stored, the heat in the heat storage layer is exchanged from the floor 14, the foundation 11, and the heat storage exchange layer 25 and flows into the house 10, so it accumulates in the house and feels uncomfortable. Do not store heat due to high temperature. In addition, it is natural that the heat storage period may be executed at an arbitrary time based on the local climate, the user's sensible temperature, and the like.

  First, warm air is collected at the roof 13 in order to allow warm air to flow into the first duct 33 from the duct inlet 32. As shown in FIGS. 2 and 3, the roof 13 has a ventilation layer 31 formed on the entire surface of the south roof surface 13 </ b> A. In this roof 13, a plurality of roof rafters 44 are spanned between the beams 42 and 43, and a structural plywood 45 is laid on these roof rafters 44. A heat insulating material 47 is installed, and a plurality of ventilation rafters 48 as ventilation layer forming members are arranged on the heat insulating material 47, and a roof finishing body 49 is laid on the ventilation rafter 48. The ventilation layer 31 is formed between the heat insulating material 47 and the roof finish 49 by the presence of the ventilation rafters 48.

  The roof finished body 49 is obtained by installing a metal plate 52 on a structural plywood 50 through a roofing 51. The metal plate 52 is preferably a copper plate, a stainless steel plate, a galvanium steel plate, or the like having good thermal conductivity, and any of them may be painted in a dark color such as black to enhance heat absorption. Instead of the metal plate 52, a color vest (registered trademark) may be used.

  The duct inlet 32 of the first duct 33a opens into the ventilation layer 31, and as shown in FIG. 3, is located at a center position in the left-right direction of the south roof surface 13A and from a water edge 53 of the south roof surface 13A. The distance a is set to a position closer to the center in the vertical direction. The predetermined distance a is set as a ratio with respect to the distance L between the water upper edge 53 and the water lower edge 54 of the south side roof surface 13A, and is set to a value in a range of about 1/5 <a / L <about 1/2. Is preferred. By setting the value of the predetermined distance a within the above range, air (warm air) heated by solar heat through the ventilation layer 31 is introduced into the duct inlet 32 of the first duct 33a. .

  The ventilation rafters 48 that form the ventilation layer 31 between the heat insulating material 47 and the roof finish 49 are arranged obliquely at an inclination angle α in the direction toward the duct inlet 32 of the first duct 33a, and are parallel to each other. A plurality are provided. This inclination angle α is, for example, 45 degrees. Also, as shown in FIG. 2, an eaves lower member 55 is provided under the eaves of the roof 13, and an air inflow port 56 is formed in the eaves lower member 55. A ridge member 57 is installed in the ridge of the roof 13, and an air outflow inlet 58 is formed in the ridge member 57.

  As shown in FIG. 1, the warm air is ventilated from the air inlet 56 and the air outlet 58 through the lower edge 54 and the upper edge 53 of the south roof surface 13 </ b> A by the operation of the first fan 34 in winter. While flowing into the layer 31 and flowing toward the duct inlet 32 along the plurality of ventilation rafters 48 of the ventilation layer 31, it is warmed by solar heat or radiatively cooled, and the first through the duct inlet 32. It is introduced into one duct 33a.

  The first fan 34 is linked to a temperature sensor (not shown), and it is desirable that the first fan 34 starts operation when the warm air is at a temperature of 30 degrees or more. The warm air warms up to about 60 to 70 degrees in summer and about 45 degrees in winter. Therefore, the first fan 34 is operated for a considerable time even in winter, and a considerable amount of the warm air flows from the duct inlet 32. It will be introduced into one duct 33a.

  The warm air flowing in the first duct 33a is sent to the second duct 33b via the first fan 34. The second duct 38 passes through the floor 14 and the foundation 11 and blows the warm air into the steel pipe 22 provided in the heat storage exchange layer 25. The warm air blown into the steel pipe 22 exchanges heat with the steel pipe 22, and the steel pipe 22 is warmed by the heat of the air.

  Next, the mountain sand 23 is warmed by heat exchange between the heat of the steel pipe 22 and the mountain sand 23 circumscribed. Since the mountain sand 23 covers the entire steel pipe 22, the mountain sand 23 can efficiently absorb the heat generated from the entire steel pipe 22. Moreover, since the steel pipe 22 meanders the inside of the heat storage exchange layer 25 and lengthens the total extension, heat exchange can be performed efficiently.

  Next, the crushed stone 24 is warmed by heat exchange with the crushed stone 24 arranged on the lower surface of the mountain sand 23. Then, the heat of the crushed stone 24 is warmed by heat exchange with the heat storage layer 21 on the lower surface of the crushed stone 24. In this way, the heat of the warm air repeats heat conduction, and finally heat is stored in the heat storage layer 21.

  The warm air passes through the steel pipe 22 and exchanges heat with the third duct 36. The tip of the third duct 36 is connected to a duct switching machine 37. When the air is discharged outdoors, the duct switching unit 37 switches the air flow in the direction of the exhaust warm air duct 39, and the air is discharged from the exhaust warm air duct 39 to the outdoors. Further, when the air is drawn into the house 10, the duct switching unit 37 switches the air flow in the direction of the indoor warm air duct 38, and the air is blown from the indoor warm air duct 38 to the house 10. In addition, the switching method of the duct switching machine 37 may be a manual method or an automatic method including a temperature sensor.

[Heating by storing heat in winter]
Next, explanation will be given for the case where heating is performed in winter using heat storage. In the winter season, cool air flows from the duct inlet 32 into the first duct 33 a and the second duct 33 b, and further cool air flows into the steel pipe 22 provided in the heat storage exchange layer 25. Since the temperature of the heat storage layer 21 is warmer than that of the air, heat exchange occurs there, and heat storage in the heat storage layer 21 occurs in the order of the crushed stone 24, the mountain sand 23, and the steel pipe 22 in the steel pipe 22 Warm the air (warm air). The hot air is discharged from the steel pipe 22, is switched in direction by the duct switching machine 37 via the third duct 36, and is blown from the indoor warm air duct 38 to the house 10. The interior of the house 10 is warmed by the warm air and can be used as heating. Moreover, when the temperature of a heat storage layer is higher than the room temperature of the house 10, the heat of the heat storage layer 21 heat-exchanges with the heat storage exchange layer 25, the foundation 11, and the floor 14, and the effect which heats the house 10 also arises.

  In this way, the indoor heat can be heated by storing the heat of air in the geothermal layer and using the heat stored in the geothermal layer in winter. Moreover, since the power supply to be used is only the power supply for the fan, an economical heating system can be constructed.

[Cool storage in cold storage]
The method of cold storage and indoor cooling will be described with reference to FIG. The cold storage period takes about two months to store in the cold storage layer on the soil, so it is estimated that it should be done before the beginning of early spring (late April) by calculating backwards from the end of June when the house needs to be cooled. It is. However, unlike the heat storage layer, there are no houses on the ground part of the livestock cooling layer, so there is no problem even if the cold air of the cool storage layer is released to the ground during livestock cooling. For this reason, it is energy efficient to cool the coolest cold air from December to February in the severe winter season to the cold stock layer. Therefore, it is preferable to implement so that the operation of the animal cooling fan 64 starts when the temperature is below a certain temperature (for example, 10 degrees or less).

  First, the cool storage fan 64 is operated in order to allow cold air to flow from the cool storage duct inlet 62 into the cool storage first duct 63. The cool storage fan 64 is linked to a temperature sensor (not shown), and it is desirable that the cool air has a temperature of 10 degrees or less and the cool storage fan 64 starts operation.

  With the operation of the cold storage fan 64, the cold air is blown from the cold storage duct inlet 62 into the cold storage first duct 63, passes through the cold storage first duct 63, and is provided in the cold storage exchange layer 75. To be blown. Since the temperature of the cold air is lower than that of the cold storage steel pipe 72, heat exchange is performed with the cold storage steel pipe 72, and the cold storage steel pipe 72 is cooled by the cold air.

  Next, the cold storage mountain sand 73 is cooled by heat exchange between the cold air of the cold storage steel pipe 72 and the cold storage mountain sand 73 circumscribed. Since the cold storage mountain sand 73 covers the entire cold storage steel pipe 72, the cold storage mountain sand 73 can efficiently absorb the cold air generated from the entire cold storage steel pipe 72. Moreover, since the steel pipe 72 for cold storage meanders the inside of the cold storage exchange layer 75 and lengthens the total extension, heat exchange can be performed efficiently.

  Next, the cold air with the cold storage mountain sand 73 cools the cold storage crushed stone 74 by heat exchange with the cold storage crushed stone 74 arranged on the lower surface of the cold storage mountain sand 73. The cold storage layer 71 is cooled by heat exchange with the cold storage layer 71 on the lower surface of the cold storage crushed stone 74. In this way, the cold air repeats heat conduction, and finally cold air is stored in the cold storage layer 71.

  The cold air passes through the cold storage steel pipe 72 while exchanging heat, and is sent to the cold storage second duct 66. The tip of the cold storage second duct 66 is connected to a cold storage duct switching machine 67. The cold storage duct switching machine 67 switches the flow of air to the exhaust cooling storage duct 69 when discharging the air outdoors, When the air is blown into the house 10, the air flow is switched to the indoor cool air duct 78. The switching method of the regenerative duct switching machine 67 may be a manual method or an automatic method including a temperature sensor.

  Thus, in order to store heat in the cool storage layer 71, cold air flows in from the cool storage duct inlet 62, and air is discharged from the exhaust cool storage duct 69 to the outside.

[Cooling method]
Further, in the summer, air flows from the cool storage duct inlet 62 into the cool storage first duct 63, and further, hot air flows into the cool storage steel pipe 72 provided in the cool storage exchange layer 75. Since the temperature of the cold storage layer 71 is lower than the heat, heat exchange occurs there, and the heat storage of the cold storage layer 71 is performed in the order of crushed stone 74 for cold storage, mountain sand 73 for cold storage, and steel pipe 72 for cold storage. This occurs and cools the hot air in the cold storage steel pipe 72 (cooling air). The cooling air is discharged from the cold-storage steel pipe 72, and the direction is switched by the cold-storage duct switching machine 67 via the cold-storage second duct 66, and is blown from the indoor cold air duct 68 to the house 10. The inside of the house 10 is cooled by the cooling air and can be used as a cooling.

  In this way, it is possible to cool a house by storing warm air heat in a geothermal layer and using the heat stored in the geothermal layer in winter. Further, since the power source used is only the power source of the fan, an economical cooling system can be constructed.

[Second Example]
A second embodiment according to the present invention will be described with reference to FIGS. FIG. 5 is a cross-sectional view showing a house to which the second embodiment of the heat storage air-conditioning system according to the present invention is applied, FIG. 6 (A) is a cross-sectional view showing a second heat collecting plate, and FIG. ) Is a front view of the second heat collecting plate.

To do. This air passes through the ventilation gap 96 in the ventilation layer 87, moves along the partition plate 90, and snakes and flows in the ventilation layer 87. During this time, the air is heated by solar heat or radiatively cooled to the duct inlet 132. The warm air flows from the duct inlet 132 into the veranda blindfold duct 121 and the veranda floor duct 122 and is guided to the first duct 133a. The air guided to the first duct 133a is blown to the second duct 133b by the first fan 34, and further blown to the heat storage exchange layer 25 connected to the second duct 133b. In the heat storage exchange layer 25, heat exchange between the warm air and the heat storage layer 21 is performed, and heat is stored in the heat storage layer 21.

  In the present embodiment, instead of the second heat collecting plate 140, a material obtained by downsizing the heat collecting body 40 may be used.
