Description

  The present invention relates to a building heating apparatus, for example, a direct heating apparatus using direct heat that is used for heating in winter by storing direct heat obtained in summer in soil in the ground.

  Heating using solar energy, for example, obstruction of expansion and remodeling by installing a heat storage layer outdoors, construction period and cost by installing a heat storage layer in the floor, and maintenance difficulties. In order to solve this problem, an air collector, solar water heater, etc. installed on the roof of the building is used as a solar energy collector, and air or hot water sampled from the heat collector in the daytime is passed through a pipe between the roof and the floor. The building is heated at night by the radiant heat of the heat storage material by guiding it to the heat storage layer installed below the floor, dissipating heat to the heat storage material filled in the heat storage layer, and storing the heat in the heat storage material. Things have been proposed.

JP-A-8-193722

  In this case, it is possible to contribute to energy conservation by heating the solar energy effectively, but by installing solar energy collectors such as air collectors and solar water heaters on the roof of the building, Apart from flat roof structures, roofs commonly used in houses, such as gable roofs, dormitory roofs, and single-floored roofs, do not harmonize with the design of the building by installing these heat collectors, and the appearance of the building In many cases, it causes a sense of incongruity, and the problem remains that it is difficult to disseminate. Even if a heat storage tank is used to make effective use of solar energy, heating is unnecessary in the summer, so it is used to store solar energy during the daytime in the winter and to heat it at night. Heating is not always possible due to the short solar radiation time in winter and the solar energy is weak, and in the case of cloudy weather, rainy weather, or when there is snow on the roof, it depends on solar energy. There remains a problem that heating cannot be done without heat collection itself. In order to compensate for this, for example, heat pumps may be used to supplement winter heating and further cooling. In this case, however, the system will inevitably become complicated and the installation costs will increase. The problem that it is easy to invite arises.

  The present invention has been made in view of such circumstances, and the problem to be solved is to give the appearance of the building a structure that is as simple as possible and rich in durability and installation costs as low as possible. A direct-heating-type heating device that eliminates the influence or reduces it as much as possible, but enables continuous heating at a stable temperature regardless of the day and night, regardless of the weather. To provide.

  As a result of diligent research in line with the above-mentioned issues, building roofs, wall roofing materials, exterior materials such as siding, and concrete enclosures reach a high temperature of about 80 ° C during direct sunlight, for example, during summer days. When heated, these exterior materials and concrete frames have direct heat (including their ambient temperature). For example, on the back of the exterior material, that is, on the roof, the space between the rafters on the back of the field plate, the back of the siding If pipes are arranged in the space between the torso, in the middle of the concrete frame in the thickness direction, etc., it will be possible to collect heat into the fluid in the pipes by the direct heat of the exterior materials and concrete frames and the ambient temperature, Although there are some differences depending on the type, the soil generally has poor thermal conductivity, but it takes time to repeat the heat dissipation of the collected fluid over time, so that the soil directly under the building It is possible to store the above-mentioned direct heat in the heat storage layer, that is, the surface of the earth is generally greatly affected by the outside air temperature, and the temperature changes drastically. For example, the temperature change width at a depth of 2 to 3 m is only a few degrees per year, and the temperature change occurs several months later than the outside air temperature. However, it takes about several months to store heat in the soil based on this poor thermal conductivity. Therefore, the direct heat in the summertime puts the soil directly under the building around July-September. If the heat is stored over several months, the heat radiated heat generates a lag of several months between the period when solar energy of direct heat is obtained and the period when heating is required. It can be used for geothermal heating in winter, and the heating temperature in winter varies depending on the amount of stored energy. The amount of stored energy is the period of heat collection and the volume of soil as the heat storage body, In other words, since the geothermal heating area is constant, it can be controlled by the depth from the ground surface, and in order to collect direct heat and store it in the soil, piping for heat collection on the roof and / or wall surface. On the other hand, by installing piping for heat dissipation in the ground and forming a piping system for fluid circulation between them, it is possible to simplify the installation as much as possible, avoiding high installation costs, and enabling troubles and maintenance. It can be made unnecessary or reduced as much as possible, and if piping is placed in the space behind the exterior material and embedded in the concrete frame, the piping for heat collection is uncomfortable. The possibility of damaging the appearance of the building by exposing it to roofs and walls that give rust can be eliminated, and for example, if siding with grooves is used on the wall surface, it will feel strange even if exposed Similarly, the possibility of damaging the appearance of the building can be eliminated. Therefore, the soil temperature is about 25 to 30 ° C. by storing the soil directly under the building by direct heat in summer, for example, about 10 to 15 ° C. in Tokyo. Therefore, if this is used as heating in winter, it is possible to perform continuous heating at a stable temperature regardless of day or night according to the volume of the soil. In other words, the invention according to claim 1 is arranged on the roof and / or wall of a building and the fluid heat collecting pipe for collecting the direct heat of the roof and / or the wall surface; Underground soil directly under the building A fluid heat dissipating pipe that radiates heat to the ground and stores the ground soil as a heat accumulator, and a fluid circulation pipe that connects the fluid heat collecting and fluid heat dissipating pipes to circulate the fluid between them. It is a direct-heat-use heating device characterized by being provided in series.

  In addition to the above, the invention described in claim 2 can be used in addition to the above-described geothermal heating by the soil of the heat storage body without using the collected solar energy for the heat storage when the direct heat in winter is weakened. In addition to the fluid heat collection, fluid heat radiation and fluid circulation pipes, this is added to the floor or foundation of the building so as to improve the daytime heating effect by directly dissipating the heat. The direct heat utilization heating device according to claim 1, further comprising a series of fluid heating pipes arranged on the concrete and directly dissipating heat by switching the fluid to the fluid heat radiation pipe. It is a thing.

  In addition to the above, the invention according to claim 3 is generally a heat storage body where heat storage to the soil by direct heat in summer takes time due to the poor thermal conductivity of the soil. If the depth of underground soil is less than 1 m, the heat storage body's underground soil lacks the amount of heat stored, so it is suitable for winter heating, for example, at a temperature of about 25-30 ° C. If it cannot be performed, and if it exceeds 5 m, the underground soil volume of the heat storage body will be excessive, and it will be impossible to store heat at a temperature suitable for heating in the winter season due to direct heat in summer. As for the installation of the pipe, the depth of 1 to 5 m can be a preferable form for continuously performing the heating in the winter at a stable temperature. , 1-5 from the ground surface directly under the building 3. The direct heat utilization heating device according to claim 1 or 2, wherein the fluid heat radiation pipe is embedded and arranged at a set depth position within the range. It is.

  In addition to the above, the invention described in claim 4 uses pipes for piping and increases the area of heat collection and / or heat dissipation as much as possible to reduce the heat collection and / or heat dissipation by piping. In order to make the piping and its installation work as simple as possible and to be low-cost, it is possible to meander the above fluid heat collection piping and / or fluid heat radiation piping, 2. An arrangement such as bending, spiral winding, etc. is formed by a series of pipe pipes for fluid transfer with an increased area of heat collection and / or heat dissipation with respect to a linear arrangement. , 2 or 3.

  In the invention of claim 5, in addition to the above, even if the cost is somewhat increased, the area of heat collection and / or heat dissipation is similarly increased by making the piping in a cross-girder or lattice shape. Since it is possible to expand as much as possible and heat collection and / or heat radiation by piping can be performed as effectively and reliably as possible, this can be applied to the above-mentioned fluid heat collection and / or fluid heat radiation piping in the surface direction. It is formed by a single or multiple-connected fluid transfer grid or grid-like pipe formed by a pair of end pipes and a plurality of branch pipes connecting the pair of base pipes in the crossing direction. The direct heat utilization heating apparatus according to claim 1, 2, or 3.

  The present invention uses each of these as the gist of the invention as means for solving the above problems.

  Since the present invention is configured as described above, the invention according to claim 1 is piped to the roof of the building, the roof of the wall, the space behind the exterior material such as siding, the intermediate part in the thickness direction of the concrete frame, etc. The solar energy of direct heat is obtained by storing the heat collected by the direct heat or the ambient temperature of these exterior materials and concrete frames as heat storage layer using the soil with poor thermal conductivity as the heat storage layer. By utilizing the time lag of several months between the period when the heating is required and the period when heating is required, continuous heating at a stable temperature regardless of the day and night is possible regardless of the weather throughout the period when heating is required. Direct radiation that can be done and has a simple structure as much as possible, has high durability, reduces installation costs as much as possible, and eliminates or reduces the impact on the exterior of the building as much as possible It is possible to provide the use of heating equipment.

  In addition to the above, the invention described in claim 2 can be used in addition to the above-described geothermal heating by the soil of the heat storage body without using the collected solar energy for the heat storage when the direct heat in winter is weakened. By using for direct floor heating, the heating effect in the daytime can be improved.

  In addition to the above, the invention according to claim 3 is provided for continuously heating at a stable temperature in winter by setting the piping for underground soil to a depth of 1 to 5 m from the ground surface. It can be set as a preferable form.

  In addition to the above, the invention described in claim 4 uses pipes for piping and increases the area of heat collection and / or heat dissipation as much as possible to reduce the heat collection and / or heat dissipation by piping. It can be performed as effectively and reliably as possible, and the piping and the arrangement work thereof can be simplified as much as possible to reduce the cost.

  In addition to the above, the invention according to claim 5 is also capable of reducing the area of heat collection and / or heat dissipation in the same way by making the pipes in a cross-girder or lattice shape, although the cost is somewhat increased. Therefore, heat collection and / or heat dissipation by piping can be performed as effectively and reliably as possible.

  Hereinafter, the present invention will be described in more detail with reference to the example of the drawings. Reference numeral 1 denotes a building in the present example, for example, a wooden house having a gable roof, and the building 1 is a heating device using direct heat. 2 is used for heating in the winter using solar energy in the summer. The heating device 2 includes a fluid heat collection pipe 21, a fluid heat radiation pipe 22, and a fluid circulation pipe 23 in series. The fluid heat collecting pipe 21 is arranged on the roof 11 of the building, that is, the wooden house, and heats the direct heat of the roof into a fluid. Radiates heat to the underground soil directly under the building 1 to store the underground soil as a heat storage body 3, and the fluid circulation pipe 23 includes the fluid heat collection and fluid heat radiation pipe 21. , 22 are connected to circulate fluid between them. Some as being. In this example, these pipes are formed by a series of pipe pipes for fluid transfer, for example, by connecting them to each other at necessary places to make the total length of the above-mentioned pipes. In the present example, the heat dissipating pipe is arranged in a straight line, and in this example, the heat dissipating pipe is arranged in a meandering, bent, spiral winding, etc., for example, a spiral winding arrangement. The area of heat dissipation is expanded with respect to the arrangement, and the residence time of the fluid in the soil with poor thermal conductivity is extended so that the heat storage by the heat dissipation can be improved as much as possible.

  That is, the heating device 2 of this example includes a roof 11 that receives direct sunlight from the building 1 and a building having poor thermal conductivity by the fluid heat collection pipe 21, the fluid heat radiation pipe 22, and the fluid circulation pipe 23. By forming a fluid circulation system with the heat storage body 3 by the underground soil directly under the object 1, the solar energy at the time of direct sunlight is a geothermal heating at the time when the outside temperature falls with a time lag of several months At this time, the building 1 is used between the building 1 and the heat storage body 3 by the foundation, in this example, a cloth foundation, in order to use the heat storage energy immediately below the building 1 for heating. Ventilation openings are not installed in the foundation so that the underfloor space is blocked from outside air, or can be opened and closed even when installed, and the ventilation openings are closed during the heating period. Heat storage from underfloor space Energy is are to be prevented from releasing to the outside.

  In the building 1 of this example, the gable roof is provided with the fluid heat collecting pipe 21 on the entire surface in this example, and the pipe is made of a relatively soft metal such as aluminum or copper. The above series of pipes that can be bent by forming a relatively soft synthetic resin such as vinyl chloride or polyethylene, or a composite material obtained by coating the above relatively soft metal with an appropriate synthetic resin such as polypropylene or vinyl chloride. The pipe is placed and fixed on the space between the rafters 14 on the back of the roof 11, for example, on the abandoned rafters and abandoned ground plates installed below the rafters 14 for supporting the heat insulating material in the cabin. In the space between the rafters 14, it is arranged in a straight line along the roof surface, or in the case of a conventional hut assembly, it is supported and fixed to the lower surface of the field board and is also arranged in the same straight line in the space between the rafters 14. For example, the space between the rafters 14 is used for placement by fixing the rafters. At this time, the ends of the series of pipe pipes are, for example, the rafters 14 on the eaves side and the ridge side. Are bent so as to straddle the front and rear, and the direction thereof is changed, and is further arranged in a series on the entire surface of the roof 11 so as to be further extended in the space between the adjacent rafters 14. For example, pipes having a predetermined length are connected using joints, and both ends of the pipes are connected to ends of a fluid circulation pipe 23 described later using joints. It is. By arranging the fluid heat collecting pipe 21 on the roof in this way, the roof of the building 1 receives direct sunlight, and is heated directly to, for example, about 80 ° C. in the summer to directly heat the lower surface of the roof 11. Heat is collected from a fluid passing through the fluid heat collecting pipe 21 as a flow path. Further, both ends of the pipe are connected to ends of a fluid circulation system pipe 23 described later using the same joint.

  In the ground immediately below the building 1, the fluid heat radiation pipe 22 is arranged so as to cover an area that is the same as or slightly smaller than the floor area of the building 1 in this example, and the ground soil is stored as a heat storage body. 3, the direct heat of the roof is stored in this, and the underground soil as the heat storage body 3 at this time is in the range from 1m to 5m deep from the ground surface directly under the building. The fluid heat radiation pipe 22 is set and embedded at the set depth position within the range. In this example, the pipe is embedded at a depth of 3 m from the ground surface and arranged. It is as a thing. At this time, in this example, the underground soil heat storage body 3 is formed as a heat storage tank of the heat insulating wall 34 by surrounding its outer periphery with a heat insulating material. The heat insulation is performed as effectively as possible directly under the building 1.

  The fluid heat radiating pipe 22 is formed of the relatively soft metal, the relatively soft synthetic resin, or the composite material similar to the fluid heat collecting pipe 21 and can be bent or spirally wound. It is assumed that the arrangement was made by embedding the foundation 16 at the time of the new construction of the building 1, in this example, by burying it directly under the building 1 before or after installing the cloth foundation. In the example, the fluid heat radiation pipe 22 is buried by using a small excavating construction machine such as a mini excavator, for example, at a depth of 3 m, for example, several tens of centimeters. A buried groove 31 having a width of about 1 m is excavated, and a series of pipe pipes similar to the fluid heat collecting pipe 22 are arranged on the bottom surface of the buried groove 31 in this example by the spiral winding. , Then backfill the excavated soil In this example, an appropriate heat insulating panel such as a closed cell foam resin or a metal or synthetic resin panel filled with this is laid on the bottom surface of the embedded groove 31. It is assumed that the pipes have been arranged. At this time, the pipes are arranged between the embedded grooves 31 such that, for example, both ends thereof are raised to the vicinity of the ground surface and are buried shallowly in the vicinity of the ground surface so as to form a spiral in the adjacent embedded groove 31. In the present example of forming the heat storage tank of the heat insulating wall 34, the soil wall end between the embedded grooves 31 is placed before and after the bottom of the surrounding groove to be excavated for forming the heat insulating wall 33. By bending so as to straddle, the direction is changed, and the space between adjacent embedded grooves 31 is arranged to form a spiral, and the pipe pipe is spiraled in all the embedded grooves 31 formed immediately under the building 1. A series of arrangements are made by winding them in a shape. At this time, pipes of the predetermined length are similarly connected using joints, and both ends of the pipe are connected to the ends of the fluid circulation pipe 23 described later with respect to the roof. Similar to the fluid heat collection pipe 21, they are connected using a joint.

  For example, the soil in the ground by the heat insulating material forming the heat storage layer of the heat insulating wall 33 is, for example, a plurality of the embedded grooves 31 positioned on the outermost side in the embedded groove 31 as a part of the surrounding wall 33. As in the case of the heat insulating material 32, the heat insulating material such as a closed cell foam resin or a heat insulating material made of a metal or synthetic resin panel filled with the heat insulating material is continuously attached in the outer peripheral direction. In addition, the enclosure with the heat insulating material is formed by using an enclosure groove having an appropriate depth equivalent to the embedded groove 31 so as to surround the outer periphery of the area portion of the building 1 using, for example, the above-described mini excavator. Excavate and place the thermal insulation material in the surrounding groove so as to be continuous in the outer circumferential direction, and backfill the soil in the space between the surrounding groove and the panel, or foam the closed cell in the surrounding groove. Fill the resin and Depending situ formed foam wall Te, it is also possible to perform this.

  When installing the fluid heat radiation pipe 22, it is possible to arrange it by excavating the entire surface directly under the building 1 having an area the same as or slightly smaller than the building floor of the above building into a hole shape. By excavating the embedded groove 31, the construction machine used for the excavation can be a construction machine for small excavation such as the mini excavator, and the construction is simpler than the excavation of the entire hole shape. And its cost can be reduced.

  The fluid heat collecting and fluid heat radiating pipes 21 and 22 are connected to the longitudinal ends of each series of pipes, and the fluid circulation pipes are connected to circulate fluid between them. 23. At this time, both ends of the fluid heat collection pipe 21 and the fluid heat radiation pipe 22 of this example are connected to, for example, the entrance corner, the exit corner of the building 1, the inner side or the outer side of the wall surface. The fluid circulation pipe 23 is arranged at one location around the building 1 at the corresponding position. That is, the fluid circulation pipe 23 in this example is a pipe pipe made of the same metal, synthetic resin or a composite material thereof as the fluid heat collecting and fluid heat radiating pipes 21 and 22 with the forward path and the return path as a pair, or the pipe. For example, pipes made of other materials such as steel pipes, for example, are connected to one end of the heat collecting and heat radiating pipes 21 and 22, respectively. In this case, the pipes of the fluid circulation pipes are arranged by connecting the pipes of a predetermined length using joints in the same manner.

  On one side of the fluid circulation pipe 23 that forms a pair of the forward path and the return path, a pump 25 that can be operated and stopped by a switch, for example, supported by a bracket on the wall surface of the building or placed on the ground surface. The fluid is forcibly circulated through the series of fluid heat collection pipes 21, the fluid heat radiation pipes 22 and the fluid circulation pipes 23 by the pump 25, and the fluid heat collection pipes 21 arranged on the roof 11. The fluid collected in step 1 is guided to the fluid heat radiation pipe 22 via the forward circulation pipe, radiated to the ground soil as the heat storage body 3, and stored in the ground soil. The fluid is circulated through these pipes so that the heat is collected again through the pipe 21 for fluid heat collection. By repeating this, the direct soil heat of the solar energy is utilized and the underground soil by fluid circulation is used. Heat storage to It is to Migihitsuji. At this time, it is preferable that the switch is an automatic switch that is operated and stopped by a temperature sensor installed in the fluid heat collecting pipe 21, for example, so that the pump 25 can be turned on and off at an appropriate time for heat storage. Activation and deactivation can be automated.

  In the direct heat utilization heating device 2 of this example, in addition to the fluid heat collecting, fluid heat radiating and fluid circulation pipes 21, 22, 23, it is arranged on the floor of the building 1 or the foundation concrete 17, A series of fluid heating pipes 24 that directly dissipate heat by switching the fluid with the fluid heat radiation pipes 22 are provided. In this example, the fluid heating pipes 24 are the fabric foundation of the building 1. The foundation concrete 17 in which concrete is cast and formed between 16, that is, embedded in the middle of the moisture-proof concrete in the thickness direction, can be directly radiated to the foundation concrete 17 from the roof. At this time, the switching is performed by, for example, installing a fluid switching switch in the fluid circulation pipe 23 together with the switch of the pump 25, and the fluid switching switch is operated by a temperature sensor, for example, as described above. It is preferable that the automatic switching of the stop is performed, so that, for example, the pump 25 is automatically operated and stopped during the daytime in the winter when heat can be collected and during the nighttime when the heat cannot be collected. It is possible to prevent the foundation concrete 17 from being cooled by operating in this manner.

  In this example, the fluid circulating through the fluid circulation pipe 23 to the fluid heat collection pipe 21 and the fluid heat radiation pipe 22 to the fluid heating pipe 24 in the present example is water, oil, or the like. In this example, water with antifreeze added is used so as to eliminate the possibility of freezing in winter, for example. After the circulation piping system is arranged in the building 1 and the underground soil, the fluid is injected from an inlet provided in an appropriate piping of the piping system, and the fluid is circulated by the operation of the pump 25. I have to do it.

  In the figure, 12 is a roofing material, 13 is a base plate, 15 is a heat insulating material disposed on the discarded base plate in the roof 11, and 34 is a heat storage energy of the heat storage body 3 of this example which is a heat storage layer of a heat insulating wall 33. The base heat insulating material arrange | positioned between the inner side of this foundation 16 and the foundation concrete 17 is shown so that it may prevent discharge | release through.

  The direct heat utilization heating device 2 of this example formed in this way forms a circulation piping system in which a fluid is circulated by a fluid heat collection pipe 21, a fluid heat radiation pipe 22, a fluid heating pipe 24, and a fluid circulation pipe 23. Thus, for example, in the summer season when direct heat is strong, heat is collected from the roof 11 of the building 1 by direct heat, and heat is radiated to the underground soil by the fluid heat radiating pipe 22. Heat storage body 3, in this example, heat is stored as a heat storage layer of the heat insulation wall 33, and for example, heating is necessary by taking advantage of the time lag of several months between the time when the direct heat is obtained and the time when heating is required. In addition to being able to perform continuous geothermal heating at a stable temperature regardless of day or night at around 20-23 ° C, it is possible to use the floor when heating is necessary during the daytime such as in winter when the direct heat is weak. Heating period and Similarly, heat is collected from the roof and dissipated to the fluid heating pipe 24 to provide direct heating assistance for the building in addition to the above continuous heating, while heat storage or floor heating is unnecessary or inappropriate. During the time period, the pump 25 can be stopped to stop heat collection and heat dissipation, thereby making effective use of direct heat from solar energy as much as possible to save energy in the building 1. Can be possible. The direct heat utilization heating device 2 uses the solar energy. The fluid heat collection pipe 21 is disposed in the space between the rafters 14 on the back of the roof plate of the roof 11, and the fluid heat radiation pipe 22 is constructed. While the underground soil directly under the object 1 is buried in the ground as the heat storage body 3, when the fluid circulation pipe 23 is arranged along the wall surface of the structure 1 or when the pump 25 is installed outdoors, these are built. Although they are exposed to the outside of the object 1, the possibility of damage to the external appearance of the building 1 is extremely small. Therefore, the possibility of damage to the external appearance due to the installation of the heating device 2 can be eliminated. In addition, since the heat storage used for heating is performed by using the underground soil as the heat storage body 3, the heat storage layer may damage the landscape or become an obstacle to renovation by installing a heat storage layer outdoors. In addition to eliminating the possibility of breakage due to the influence of typhoons and strong winds by disposing the fluid heat collection pipe 21 in the space between the rafters 14 on the back of the roof 11, for example, it is possible to eliminate the rain. The effect can be avoided and trouble free. Furthermore, in this example, since a fluid circulation piping system that collects and heats the fluid is formed by a series of pipe piping, the structure itself can be made as simple as possible and rich in durability. In addition, the installation cost of the heating device 2 can be made as low as possible by reducing the cost.

  The example shown in the figure is as described above. For example, in the case of a building having a flat roof, the appearance of the building is not impaired even if the fluid heat collection pipe is placed and fixed on the roof surface. However, the pipe for heat collection can be arranged in the space in the roof, and in particular in concrete buildings, it can be installed embedded in the middle of the thickness direction of the concrete roof to collect heat from direct heat of the concrete. . When arranging the fluid heat collection pipe on the roof, it is generally sufficient to arrange it in a straight line. However, for example, the pipe for the fluid heat collection pipe is arranged only on the south inclined surface such as a gable roof or a dormitory roof. In this case, it is possible to improve the heat collecting efficiency by extending the roof residence time of the fluid by meandering, bending, spiral winding and the like. Instead of the pipe pipe, the heat collecting and / or heat radiating pipe is formed by a single base pipe having a pair of base ends and a plurality of branch pipes connecting the pair of base pipes in the cross direction. It shall be formed of one or more connected fluid transfer grids or grid-like pipes, and the fluid heat collection pipes may be placed on the wall of the building instead of the roof or together with the roof, In this case, for example, the outer wall of the wall is a galvanium steel plate or aluminum siding with a groove, and the pipe pipe is inserted and arranged in the groove so that the fluid is applied to the surface of the building. Although heat collection piping is arranged, the piping should be prevented as much as possible from deteriorating the appearance of the building, and the fluid heat radiation piping should be arranged directly under the building where the entire surface has been excavated in a hole shape. In the recess, through or through a heat insulating material as above. In this case, the pipes for heat radiation are arranged in a superposed manner in the vertical direction, that is, in the depth direction, or the depth of the heat radiation positions is plural in the depth direction. The heat storage efficiency is improved by arranging in a plurality of different layers, and the fluid heating piping is arranged on the floor of the building, and instead of the foundation concrete, the surface layer of the heat storage body Or to arrange it in a shallow part, make the building other than a residential use such as a public facility, for example, a gable roof, a dormitory roof, etc. Thus, by switching the plurality of pipes so as to track the sun and operating the fluid circulation system, the heat collection efficiency is improved as much as possible in response to places where solar radiation conditions are insufficient, such as in urban areas. In this case Umate, when placing the heat pipe adopted fluid on a plurality of surfaces or the entire surface of the cardinal, changes piping density depending on its orientation, it like can also be similarly so as to improve the Tonetsu efficiency. In carrying out the present invention, including these, buildings, roofs, walls, pipes for fluid heat collection, pipes for heat radiation, heat storage bodies, pipes for fluid circulation, pipes for fluid heating used as necessary, pipes Specific materials, shapes, structures, dimensions, relations, additions to these, specific methods for piping arrangement, etc. As long as it is not contrary to the gist of the invention, various forms can be adopted.
