Description

  In the present invention, fresh outside air supplied to the indoor side by a total heat exchange type exhaust fan installed in the room of the building is sent to the lower part of the first floor of the building, and the lower part is formed in a U-shape on the foundation floor under the first floor. A plurality of underground heat recovery pipes are buried in the ground so that both ends protrude from the foundation floor to the lower part of the first floor. A blower is attached to one end of the underground heat recovery pipe, and the blower is operated to operate the first floor. The air inside the underfloor is sucked into the underground heat recovery pipe, and the air sucked into the underground heat recovery pipe is warmed in the underground heat recovery pipe by the underground heat in the winter and underground in the summer. The air cooled in the underground heat recovery pipe by heat is supplied to the lower part of the first floor, and the air under the first floor is supplied to the inside of the ceiling of each floor via the duct and supplied to the inside of the ceiling. Air is supplied to the room from the gallery provided on the ceiling of each room. To an apparatus for performing the room temperature adjustment.

  Conventional room temperature adjustment in small houses has been using air conditioners in the summer and cooling and heating using energy such as electricity, gas, and oil in the winter. From the viewpoint, it is an urgent need to reduce CO2 emissions accompanying energy consumption, and reduction of energy consumption and further replacement with natural energy are urgently desired.

  Along with this, as a means of utilizing natural energy, what is currently widely used is a solar water heater (thermal efficiency 50-60%) and solar power generation (conversion efficiency 10-15%) using solar energy. However, in both cases, energy-saving technology that uses only solar energy is easily affected by the weather and cannot be used alone because of its instability, and it has been used in combination with other energy. There is a need for further improvements.

  On the other hand, the underground 4 to 5 m underground maintains a stable temperature throughout the year, so that it is cooler than the outside air in the summer and warmer than the outside in the winter. For this reason, facilities that use geothermal heat have been experimentally constructed in large buildings and public facilities, but the method of use is to preserve the ice made in nature during the winter. In general, it is common to transfer the ice to a heat storage tank in the basement in the summer to make cold water, circulate the cold water to each room and cool it. Therefore, it was necessary to replenish the heat storage layer with ice, which was not suitable for small-scale housing.

Furthermore, a heat pump system that uses geothermal heat is also used to supply hot water in the home and to cool and heat the room, but a horizontal loop system (deep a 1-2 m deep moat in the ground, In order to obtain a heat source for a house with a floor area of 100 m ² , it is necessary to embed a heat collecting pipe of 400 to 600 m, and a vertical loop method (underground) 2) is required for the construction of a well with a depth of 50 to 100m, and a pipe for heat collection is buried there. There was a problem that (electricity bill) took about 75% of the electric water heater using midnight power.

  In July 2003, the Building Standards Law was amended to require 24-hour ventilation of the room (to ventilate 0.5 times the volume of the room in one hour) as a “sick house measure”.

Therefore, the present applicant invented and applied for an “earth / solar system (two-layer type)” described in Patent Document 1 and capable of complying with the Building Standard Law. According to the present invention, two tanks, a water storage tank and a hot water storage tank, are buried in the ground, and heat exchange pipes that communicate with the 24 hour air supply pipes of each room from the outside air intake are provided in both tanks. Plumbing and filling the storage tank with rain water, ground water or tap water, filling the storage tank with hot water from the solar water heater, and operating the opening / closing valve provided in the heat exchange pipe in the summer, in the winter Using cold water in the storage tank that has been cooled with cold outside air, the outside air is passed through the heat exchange pipe in the storage tank, and the hot outside air is cooled and sent to each room, so efficient cold wind operation can be performed I can do it. In the winter season, warm water in the water storage tank that has been warmed by hot outdoor air in the summer is warmed to the low temperature water via the heat exchange vapour. Since it passes through the heat exchange pipe, it becomes possible to send warm air into each room.
Japanese Patent Application No. 2007-42895 Japanese Patent Application No. 2008-134783

  However, in the patent filed by the present applicant, two tanks, a water storage tank and a hot water storage tank, are required, which complicates the piping, increases the number of open / close valves, increases the price, and increases the construction cost. The construction period was long.

In addition, in the case of the geopower system, which is conventionally known as an air conditioning ventilation system for buildings using underground heat exchangers, in the winter season, only the underground heat alone can produce a heating effect (the underground temperature is around 18 degrees even at 5 meters underground). Therefore, even if the outside air is warmed by underground heat, the temperature is only lower than that), and the price is high, and there is a problem in terms of cost when constructing an ordinary house.
JP2007-303693A

Furthermore, in the case of OM solar known as a solar system using solar energy, there was a drawback that cold wind operation could not be performed in summer.
JP 08-005161

  In view of such conventional drawbacks, the present invention aims to harmonize with nature, suppress waste of artificial energy such as oil, gas, electricity, etc., and effectively use solar heat and underground geothermal heat. Thus, it is an object of the present invention to provide a cooling / heating device that adjusts the room temperature of a house, has a low energy cost, and has a simple structure.

  In the inventions according to Patent Document 1 and Patent Document 2 filed by the present applicant, the above-mentioned problems have occurred. Therefore, our company newly supplies a total heat exchange type exhaust fan installed in the room interior to the indoor side. Fresh fresh air is sent to the lower part of the first floor of the building, and a plurality of underground heat recovery pipes with a U-shaped lower part formed on the foundation floor under the first floor protrude from the foundation floor to the lower part of the first floor. It is buried in the ground, and a blower is attached to one end of the underground heat recovery pipe. By operating the fan, the air inside the first floor is sucked into the underground heat recovery pipe, and the underground heat recovery pipe The sucked air is warmed in the ground heat recovery pipe by the underground heat in the winter, and the air cooled in the ground heat recovery pipe by the ground heat is supplied to the lower floor of the first floor in the summer. And the air under the floor goes through the duct The interior of the floor is supplied to the ceiling, and the air supplied to the interior of the ceiling is supplied to the room from the galleries provided on the ceiling of each room, improving the device to adjust the room temperature. It was decided to go on sale.

  In order to solve such a problem, the invention according to claim 1 sends fresh outside air supplied to the indoor side by a total heat exchange type ventilation fan attached to the room interior to the lower part of the first floor of the building and the first floor. A plurality of underground heat recovery pipes with a U-shaped lower part formed on the foundation floor under the floor are buried in the ground so that both ends protrude from the foundation floor to the bottom of the first floor, and a blower is installed at one end of the underground heat recovery pipe The air inside the first floor is sucked into the ground heat recovery pipe by operating the blower, and the air sucked into the ground heat recovery pipe is ground heat recovery pipe due to ground heat in the winter season. In the summer, the air cooled in the underground heat recovery pipe by the underground heat is supplied to the lower part of the first floor, and the air below the first floor is passed through the ducts inside the ceiling of each floor. The air supplied to the interior of the ceiling Characterized in that the supply into the room from the louver provided in the well.

  In addition to the structure of claim 1, the invention described in claim 2 installs the underground heat recovery pipe in the corner of the bottom floor of the first floor floor, thereby separating the position of the underground heat recovery pipe from each other. The end protruding from the foundation bottom of the ground heat recovery pipe is configured in an L shape with respect to the foundation bottom, and the direction in which the blower of the ground heat recovery pipe sends air and the ground heat recovery pipe at another position It is characterized in that the air suction ports are configured to face each other.

  In addition to the structure described in claim 1 or 2, the invention described in claim 3 circulates warm water from a solar water heater in a hot water storage tank provided in the lower part of the first floor in the winter, and the interior under the first floor It is characterized by warming the air.

  In addition to the structure described in any one of claims 1 to 3, the invention described in claim 4 constructs a heat insulating material outside the foundation outside the foundation and uses the lower part of the first floor as an outside air adjusting tank. This is characterized in that the lower part of the first floor is configured as a sealed state cut off from the outside air.

  According to the first aspect of the present invention, in order to utilize the lower part of the first floor as an outside air adjustment tank, fresh outside air supplied to the indoor side by a total heat exchange type ventilation fan attached to the room interior is circulated indoors. Rather than sending it to the lower floor of the first floor of the building, a plurality of underground heat recovery pipes with a U-shaped lower part formed on the foundation floor under the first floor so that both ends protrude from the foundation floor to the lower floor of the first floor It is buried in the ground, and a blower is attached to one end of the ground heat recovery pipe. By operating the blower, the air inside the first floor is sucked into the ground heat recovery pipe and sucked into the ground heat recovery pipe. The air that has been melted is warmed in the underground heat recovery pipe by the underground heat in the winter, and the air cooled in the underground heat recovery pipe by the underground heat is supplied to the lower floor of the first floor in the summer. And the air under the floor on the first floor And the supply to the ceiling inside the air supplied to the ceiling inside is supplied to the room from the louver provided in each room ceiling. In this way, by using the total heat exchange type ventilation fan and the underground heat, the heat efficiency is drastically compared to the conventional case where the outside air is directly taken into the underground heat recovery pipe and heat is exchanged by the underground heat. As a result, it is possible to contribute to energy saving, shortening the construction period and drastically reducing costs.

  According to the invention described in claim 2, by installing the underground heat recovery pipe in the corner of the foundation bottom under the first floor, it becomes possible to separate the positions of the underground heat recovery pipes from each other, and The intermediate heat recovery pipes can reduce the interference of the underground heat from each other's underground heat recovery pipes. In addition, the end of the geothermal heat recovery pipe that protrudes from the foundation bottom is configured in an L shape with respect to the foundation bottom, and the direction of the ground heat recovery pipe blower that sends out air and the geothermal heat recovery pipe at a different position By configuring the air inlets to face each other, the air inside the first floor floor is agitated, and the temperature inside the first floor floor can be kept uniform so that there is no high or low temperature depending on the location. Thus, it is possible to supply air at the same temperature to a plurality of underground heat recovery pipes. By comprising in this way, it becomes possible to always stabilize the temperature of the air supplied to each floor.

  According to the invention described in claim 3, since the underground temperature in the underground 5 m in winter is around 18 degrees in the Kanto region, when the room is heated only using geothermal heat until now, It had the disadvantage of a low temperature. In the present invention, in order to improve the conventional defects, the ground heat recovery pipe is heated by circulating the hot water from the solar water heater to the hot water storage tank provided at the lower part of the first floor to warm the air inside the first floor. In addition to being able to raise the temperature of the warmed air to a higher temperature, it is also lower than the first floor when compared to conventional solar systems that use solar energy, even when it is cloudy or rainy. By using the heat source of the hot water storage tank provided in the section, it is possible to supply warm air into the room.

  According to the invention described in claim 4, the first-floor floor can be obtained by constructing the outer heat insulation material outside the foundation portion and using the lower-floor first floor as a sealed state in which the lower floor is shielded from the outside air. Not only can the temperature of the section be kept constant, but the temperature in the first floor room can be adjusted to a constant temperature, and changes in the temperature of the supply air sent into each room can be minimized.

Embodiments of the present invention will be described below.
[Embodiment of the Invention]

  1 to 5 show an embodiment of the present invention.

  FIG. 1 is an exploded view of a wooden house using the solar water heater, the hot water heat storage tank, the underground heat recovery pipe, and the total heat exchange type exhaust fan of the present invention. Hereinafter, an air conditioning system using solar heat and underground heat will be described.

  FIG. 1 is an exploded view of a wooden house 1 incorporating an earth / solar system (ground heat recovery pipe method) for easy understanding of the earth / solar system (ground heat recovery pipe method) of the present invention. Is. The solar water heater 2 is installed on the roof 3, and the warm water heated by the solar water heater 2 and indicated by an arrow 43 is attached to the upper portion of the foundation bottom 46 via the hot water pipe 42 and the hot water pipe 33. It is sent to a warm water storage tank 35 made of vinyl. The warm water sent to the warm water heat storage tank 35 warms the warm water heat storage tank 35 and becomes circulating water indicated by an arrow 44 via the recovery pipe 34 and the water supply pipe 41 and is warmed again by the solar water heater 2. Further, a foundation heat insulating material 40 is applied to the outer surface of the foundation 45, and four underground heat recovery pipes 12, 18, 22, 26 are installed on the foundation bottom board 46 inside the foundation 45, and attached to the living room. The indoor-side supplied air (fresh air) heat-exchanged by the total heat exchange type ventilation fan 4 is sent in the direction of arrow 7 through the outside air introduction duct 5 and supplied to the interior under the first floor.

  The underground heat recovery pipes 12, 18, 22, and 26 are parts of two PVC pipes that connect the lower parts of the two PVC pipes with joints, have a U-shaped lower part, and protrude to the upper part of the foundation base 46. Is attached with a joint such as an L-shaped elbow and a blower is attached to the tip of one of the elbows.

  Further, as shown in FIGS. 1 and 5, by operating the blower 10, the blower 16, the blower 31, and the blower 38, the air absorbed by the underground heat recovery pipe 6 from the direction of the arrow 143 is the underground in FIG. 1. The temperature of the heat recovery pipe 12 is adjusted by the underground heat from the direction of the arrow 11 to the direction of the arrow 13, and is discharged from the blower 10 to the inside of the first floor under the ground heat recovery pipe 9. The air discharged in this way is blown in the direction of arrow 8 and mixed with the air inside the first floor floor to adjust the temperature, and is sucked again into the underground heat recovery pipe 14 from the direction of arrow 140 to generate the underground heat. The temperature of the recovery pipe 18 is adjusted by underground heat from the direction of the arrow 17 to the direction of the arrow 19 and discharged from the blower 16 to the inside of the first floor under the ground heat recovery pipe 15. The air thus exhausted is blown in the direction of the arrow 20, mixed with the air inside the first floor, adjusted for temperature, sucked into the ground heat recovery pipe 29 again from the direction of the arrow 141, and the underground heat The temperature of the recovery pipe 26 is adjusted by the underground heat from the direction of the arrow 27 to the direction of the arrow 25, and is discharged from the blower 31 to the inside of the first floor through the underground heat recovery pipe 30. The air discharged in this way is blown in the direction of arrow 32, mixed with the air inside the first floor, adjusted in temperature, and again sucked into the underground heat recovery pipe 36 from the direction of arrow 142 to generate the underground heat. The temperature of the recovery pipe 22 is adjusted by the underground heat from the direction of the arrow 23 through the direction of the arrow 21, and is discharged from the blower 38 to the inside of the first floor under the ground heat recovery pipe 37. The air discharged in this way is blown in the direction of arrow 39, mixed with the air inside the first floor, adjusted in temperature, and again sucked into the underground heat recovery pipe 6 from the direction of arrow 143. By configuring in this way, the air inside the first floor floor does not partially stagnate inside the floor, and the temperature inside the first floor floor is adjusted to a uniform temperature.

  Thus, it became possible to collect geothermal heat efficiently by attaching one blower to each geothermal heat recovery pipe and collecting geothermal heat. In addition, by installing an air blower independently for each underground heat recovery pipe, if the air temperature inside the first floor floor is too cold (warm) in the early summer (winter), etc. By moving only a few of the underground heat recovery pipes and stopping the other underground heat recovery pipes, it became possible to adjust the temperature of the air inside the floor under the first floor.

  In the present invention, the underground heat recovery pipes 12, 18, 22, and 26 use polyvinyl chloride pipes, and the depth embedded in the ground is about 5 m. The reason is that the temperature at a depth of about 4-5m in the ground does not change much around 18 ° C throughout the year.

  In addition, in the foundation part under the first floor of a general house, in particular, the fabric foundation has a structure with good ventilation to prevent moisture in the lower part of the first floor, but in the present invention, the lower part of the first floor is outside air. In order to use as an adjustment tank, it is constructed so that the lower part of the first floor is sealed in order to prevent outside air from flowing into the lower part of the first floor.

  With the configuration as described above, the cold air operation of each room in summer will be described with reference to FIG.

  First, a method for supplying the air supplied from the total heat exchange type ventilation fan 53 and the total heat exchange type ventilation fan 55 to the indoor side to the lower first floor 90 will be described. The indoor side discharged air (contaminated room air) in the first floor room A is sucked into the total heat exchange type ventilation fan 55 from the direction of the arrow 58 and exhausted to the outside. At that time, the indoor air exhausted by the total heat exchange type ventilation fan 55 and the outside air supplied to the room are heat-exchanged by the total heat exchange type ventilation fan 55, and all the outdoor intake air (fresh air) sucked in is exhausted. As indicated by an arrow 59, the outside air introduction duct 56 is led to the lower first floor 90. Similarly, the indoor side discharge air (contaminated room air) in the second floor room B is sucked into the total heat exchange type exhaust fan 53 from the direction of the arrow 54 and exhausted to the outside. At that time, the indoor air exhausted by the total heat exchange type ventilation fan 53 and the outside air supplied to the room are heat-exchanged by the total heat exchange type ventilation fan 55, and all the outdoor intake air (fresh air) sucked in is exhausted. It is guided to the first floor lower floor 90 through the outside air introduction duct 57 as indicated by an arrow 59.

  In this way, by using the total heat exchange type ventilation fan 53 and the total heat exchange type ventilation fan 55, when the cool indoor air in the summer is replaced with the hot outdoor air, the rise in temperature can be minimized. Is possible.

  Next, how the outside air supplied in this way is subjected to heat exchange at the lower floor 90 of the first floor and becomes weakly cold air will be described. The outside air introduced from the outside air introduction duct 56 and the outside air introduction duct 57 is mixed with the air under the first floor 90, and when the blower 65 is operated, the outside air is sucked into the underground heat recovery pipe 63 from the direction of the arrow 64, and the underground heat It is cooled by underground heat in the recovery pipe 63 to become weak cold air, and is exhausted from the blower 65 to the lower first floor 90 as indicated by the arrow 66 direction. Similarly, by operating the blower 69, it is sucked into the underground heat recovery pipe 68 from the direction of the arrow 67, and is cooled by underground heat in the underground heat recovery pipe 68 to become a weak cold wind. As shown in the direction of arrow 70, the air is exhausted below the first floor 90. Similarly, by operating the blower 73, the air is sucked into the underground heat recovery pipe 72 from the direction of the arrow 71, is cooled by underground heat in the underground heat recovery pipe 72, and becomes weak cold air. As indicated by the direction of the arrow 74, the air is exhausted to the lower floor 90 of the first floor. Similarly, by operating the blower 77, it is sucked into the underground heat recovery pipe 76 from the direction of the arrow 75, and is cooled by underground heat in the underground heat recovery pipe 76 to become weak cold air. As indicated by the direction of the arrow 78, the air is exhausted to the lower floor 90 of the first floor.

  In this way, the outside air that has become slightly cold in the first floor floor 90 cools the first floor room A by cooling the first floor, and the blower 82 attached to the air supply duct 87 and the air supply duct 103. , The air in the first floor underfloor 90 that has become slightly cold air is supplied to the first floor ceiling back 91 via the air supply duct 87, and is supplied to the first floor room A from the louvers 93 and 96. Cool the room A on the first floor. Similarly, the air in the first floor underfloor 90 that has become slightly cold air in the first floor underfloor 90 is supplied to the second floor ceiling 100 via the air supply duct 103, and enters the second floor room B from the gallery 102 and gallery 99. It is supplied with air and cools the second floor room B.

  In the summer, the hot water heat storage tank 81 provided under the first floor floor 90 closes the open / close valve 110 attached to the hot water pipe 79 from the solar water heater 120, and further closes the open / close valve 113 of the recovery pipe 80, By opening the opening / closing valve 118, the water in the hot water heat storage tank 81 is drained and emptied, and the hot water heat storage tank 81 is not used in the summer.

  Of course, the warm water heated by the solar water heater 120 is opened via the hot water pipe 108 by opening the opening / closing valve 112, closing the opening / closing valve 110, closing the opening / closing valve 113, and opening the faucet 86, Hot water can be supplied to the bath via the arrow 89 to the arrow 84 direction.

  Next, the hot air operation of each room in winter shown in FIG. 3 will be described.

  First, a method for supplying the air supplied from the total heat exchange type ventilation fan 53 and the total heat exchange type ventilation fan 55 to the indoor side to the lower first floor 90 will be described. The indoor side discharged air (contaminated room air) in the first floor room A is sucked into the total heat exchange type ventilation fan 55 from the direction of the arrow 58 and exhausted to the outside. At that time, the indoor air exhausted by the total heat exchange type ventilation fan 55 and the outside air supplied to the room are heat-exchanged by the total heat exchange type ventilation fan 55, and the sucked outdoor outdoor air (fresh air) is All of the air is guided to the lower floor of the first floor as indicated by an arrow 59 via the outside air introduction duct 56. Similarly, the indoor side discharge air (contaminated room air) in the second floor room B is sucked into the total heat exchange type exhaust fan 53 from the direction of the arrow 54 and exhausted to the outside. At that time, the indoor air exhausted by the total heat exchanging ventilator 53 and the outside air supplied to the room are heat-exchanged by the total heat exchanging ventilator 53, and all the sucked outdoor outside air (fresh air) is outside air. It is guided through the introduction duct 57 to the bottom of the first floor as indicated by an arrow 59.

  In this way, by using the total heat exchange type ventilation fan 53 and the total heat exchange type ventilation fan 55, when the warm air in the room in winter is replaced with the outside cold outside air, the temperature drop is minimized. Things will be possible.

  Next, how the outside air supplied in this way is subjected to heat exchange at the lower floor 90 of the first floor and becomes a low temperature air will be described. The outside air introduced from the outside air introduction duct 56 and the outside air introduction duct 57 is mixed with the air under the first floor 90, and when the blower 65 is operated, the outside air is sucked into the underground heat recovery pipe 63 from the direction of the arrow 64, and the underground heat In the recovery pipe 63, it is warmed by underground heat to become weakly warm air, and is exhausted from the blower 65 to the lower first floor 90 as shown by the arrow 66 direction. Similarly, by operating the blower 69, it is sucked into the underground heat recovery pipe 68 from the direction of the arrow 67, and is warmed by the underground heat in the underground heat recovery pipe 68 to become low-temperature air. As shown in the direction of the arrow 70, the air is exhausted to the lower floor 90 of the first floor. Similarly, by operating the blower 73, the air is sucked into the underground heat recovery pipe 72 from the direction of the arrow 71 and is warmed by the underground heat in the underground heat recovery pipe 72 to become low-temperature air. As shown in the direction of the arrow 74, the air is exhausted below the first floor 90. Similarly, by operating the blower 77, it is sucked into the underground heat recovery pipe 76 from the direction of the arrow 75, and is warmed by the underground heat in the underground heat recovery pipe 76 to become low-temperature air. As shown in the direction of the arrow 78, the air is exhausted below the first floor 90.

  Further, in the winter season, the hot water of the solar water heater 120 is operated by opening the open / close valve 110 of the hot water pipe 108, closing the open / close valve 118, closing the open / close valve 112, and opening the open / close valve 113 to operate the water supply pump 111. The hot water in the vessel 120 flows from the direction of the arrow 122 to the direction of the arrow 131 via the direction of the arrow 106 and is stored in the hot water heat storage tank 81. Thus, the warm water stored in the warm water heat storage tank 81 warms the air under the first floor 90. Further, when the warm water that warms the warm water heat storage tank 81 is cooled in this way, it is returned to the solar water heater 120 again by operating the water supply pump 111, is warmed again by the sun 50, and passes through the warm water pipe 108. Then, warm water storage tank 81 is warmed.

  In this way, by installing the hot water heat storage tank 81 in which the hot water of the solar water heater 120 is stored in the lower floor 90 of the first floor, it is heated by the underground heat in the underground heat recovery pipes 63, 68, 72, 76. The air under the first floor 90 will be further warmed.

  As a matter of course, the warm water heated by the solar water heater 120 is opened from the arrow 89 by opening the opening / closing valve 112, closing the opening / closing valve 110, and opening the faucet 86. Hot water is supplied to the bath via the arrow 84 direction.

  In this way, the outside air that has become the low temperature air under the first floor 90 becomes the low temperature air by warming the first floor room A by operating the blower 82 while heating the first floor. The air below the floor 90 is supplied to the first floor ceiling back 91 via the air supply duct 87 and is supplied to the first floor room A from the gallery 93 and the gallery 96 to warm the first floor room A. Similarly, the air under the first floor 90 which has become low-temperature air is supplied to the second floor ceiling 100 via the air supply duct 103, and is supplied to the second floor room B from the gallery 102 and the gallery 99, Warm room B on the 2nd floor.

  As described above, in the winter season, by storing the hot water of the solar water heater 120 in the hot water heat storage tank 81, even when the cloudy or rainy day continues, the hot water stored in the hot water heat storage tank 81 is used. The air under the first floor 90 heated by the underground heat in the underground heat recovery pipes 63, 68, 72, and 76 can be further heated and supplied to the living room as a low-temperature air.

  FIG. 4 shows a state in which the wooden house 51 according to the present invention is configured by next-generation energy-saving heat insulation. Regarding the heat insulation of the roof, a roof heat insulating material 135 (generally, urethane foam having a thickness of 160 mm) is applied to the inside of the roof. Regarding the heat insulation of the outer wall, an outer wall heat insulating material 136 (generally, foamed urethane having a thickness of 75 mm) is applied to the inside of the outer wall. As for the window sash, the heat insulation sash 137 of heat insulation grade 4 (next generation energy saving type) sold by each company is used. Regarding the heat insulation of the foundation, an outside foundation heat insulating material 138 (generally, a foamed polystyrene board having a thickness of 50 mm) is applied to the outside of the foundation concrete. However, regarding the type and material of the heat insulating material written here, for example, even if it is a styrofoam plate, the heat insulating effect changes due to the difference in density. It can change.

  Regarding the heat insulation of the wooden house 51 in the present invention, in order to obtain the maximum energy saving effect, it is necessary to construct the next generation energy saving type heat insulation described in FIG.

  As mentioned above, based on the embodiment, the earth / solar system (ground heat recovery pipe system) according to the present invention has been described in detail, but the present invention is not limited to the above embodiment, Even if various modifications are made without departing from the spirit of the invention, it goes without saying that they belong to the technical scope of the present invention.

  In FIGS. 1 and 5, the shape of the hot water heat storage tank 35 for storing the hot water from the solar water heater 2 is drawn as a cube, but the shape is not limited to this, and the space between the hot water pipe 33 and the recovery pipe 34 is not limited. It is also possible to connect a long PVC pipe or a rib pipe that is easy to bend to construct a hot water storage tank. By configuring the hot water heat storage tank using such a material, even when the foundation under the first floor is configured in a complicated manner, the hot water heat storage tank can be easily constructed. Further, regarding the material of the hot water heat storage tank, although it is made of vinyl in the embodiment of the present invention, it can of course be made of FRP or a metal such as stainless steel.

  In FIG. 1 and FIG. 5, the hot water heat storage tank 35 is installed on the foundation bottom board 46, but when installing the hot water heat storage tank 35, the foundation bottom board 46 is cut out and the hot water heat storage tank 35 is inserted therein. Of course, it is also possible to embed or to place an enclosure in the place of the base bottom plate 46 where the hot water heat storage tank 35 is installed, and to install the hot water heat storage tank 35 therein. Furthermore, although the hot water heat storage tank 35 is drawn with one piece, when the foundation under the first floor is configured in a complex manner, it is possible to connect a plurality of hot water heat storage tanks.

  1 and 5, the ground heat recovery pipes 12, 18, 22, and 26 are arranged at the four corners of the foundation bottom plate 46, and this is because each of the ground heat recovery pipes recovers the heat in the ground ( This is to reduce the influence of the heat applied to the ground when heat is recovered (heat released) with the underground heat recovery pipe when it is released).

It is also possible to keep the temperature of the hot water heat storage tank 81 constant by circulating and collecting it while sending it to the hot water heat storage tank 81 by a pump.

  In FIG. 3, a temperature sensor is installed in the room, and a temperature sensor is also attached to the solar water heater 120 and the hot water heat storage tank 81, and an open / close valve for supplying water (hot water) is an electromagnetic open / close valve or a switchable electromagnetic valve. Using a valve or the like, the temperature of the room is detected by computer control, and the temperature of the room is adjusted by automatically opening and closing the opening and closing valves 110, 112, 113, and 118, and driving and stopping the water pump 111. You can also do things. Furthermore, a water temperature sensor is installed in the solar water heater 120, and a sensor for sensing the water temperature is also installed in the hot water heat storage tank 81. When the water temperature in the hot water heat storage tank 81 changes, the opening and closing valves 110 and 113 are opened and closed. It is also possible to operate the water supply pump 111 and circulate the hot water from the solar water heater 120 into the hot water heat storage tank 81.

  1 to 5, the piping space for the outside air introduction ducts 56 and 57 and the air supply ducts 81 and 103 should be piped at an optimum position regardless of the wall, floor, ceiling, or dedicated piping space. Is natural.

  Although the embodiment of the present invention has been described with respect to a wooden house, it is a matter of course that it can be applied to a steel frame house and an RC concrete house.
