Description

  The present invention does not install an air vent to the base of the building, and shuts off the air inside the first floor floor from the outside air so that it is in a sealed state. The fresh outside air to be supplied 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, both ends of the foundation floor from the foundation floor to the lower part of the first floor It is buried in the ground so as to protrude, 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 is performed. The air sucked into the pipe is warmed in the underground heat recovery pipe by underground heat in winter and a hot water storage tank is installed on the foundation bottom under the first floor, and the hot water storage tank is heated by a solar water heater. After using the warm water in the bath, leave the warm bath By flowing hot water into the hot water storage tank and storing the hot water, the air inside the first floor is further warmed, and in the summer, the air cooled in the underground heat recovery pipe by the underground heat is subsurface. And the air below the first floor is supplied to the interior of the ceiling of each floor via a duct, and the air supplied to the interior of the ceiling is supplied indoors from a gallery provided in the ceiling of each room. The present invention relates to an apparatus for performing 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 instability, and has been used in combination with other energy. There is a need for 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 400 to 600 m heat collecting pipe, and a vertical loop system (ground) 2 holes are needed for digging 50-50m deep wells, and pipes for heat collection are buried in them, and it costs 3 to 5 million yen for general housing, and the heat pump is operated. There was a problem that the cost (electricity cost) was about 75% of that of an 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

  However, in the invention of Patent Document 1 filed by the present applicant, two tanks, a water storage tank and a hot water storage tank, are required, so the piping becomes complicated, the number of open / close valves increases, and the price increases. A long construction period was also required.

Therefore, the present applicant invented and applied for the “earth / solar system (single layer type)” described in Patent Document 2. According to the present invention, in the lower part of the building, a concrete tank constructed integrally with the foundation of the building is constructed, the heat exchange pipe is piped in the concrete tank, and the rain water is laid in the concrete tank. Or, it is filled with tap water or groundwater, and the supply air from the total heat exchange type exhaust fan is led to the heat exchange pipe in the concrete tank, and in the summer, the supply air from the total heat exchange type exhaust fan is cooled by the underground heat. After heat exchange between the water in the concrete tank and the heat exchange pipe, it is cooled and then supplied to each floor via the air supply pipe.In winter, the hot water from the solar water heater is made of concrete. Circulate in the tank to make the concrete tank warm, and supply air from the total heat exchange ventilator to the heat exchange pipe in the concrete tank. After warming to heat exchange with the replacement pipe, by which the air supply to each floor through the supply pipe, it is possible to feed the hot air in each room.
Japanese Patent Application No. 2008-134783

  However, in the invention of Patent Document 2 filed by the present applicant, a concrete tank is required, so that the price is high and a construction period for construction is also long.

Therefore, the present applicant invented and filed an application of “Earth Solar System (Ground Heat Recovery Pipe System)” described in Patent Document 3. According to the present invention, there is provided a total heat exchange type ventilation fan installed in a room of a building without installing a vent hole to the outside at the foundation of the building and blocking the air inside the first floor under the outside air to be in a sealed state. Fresh outside air supplied to the inside is sent to the inside of the first floor under 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, both ends of the floor below the foundation floor. It is buried in the ground so as to protrude into the section, a blower is attached to one end of the underground heat recovery pipe, and the air inside the first floor is sucked into the underground heat recovery pipe by operating the blower, and the underground The air sucked into the heat recovery pipe is warmed in the ground heat recovery pipe by the underground heat in the winter season, and further, the hot water warmed by the solar water heater is circulated in the hot water heat storage tank provided at the bottom of the first floor Let the air inside the first floor under the floor warm, and summer The hot water from the solar water heater is not circulated in the hot water storage tank provided at the lower part of the first floor, and the air cooled in the underground heat recovery pipe by the underground heat is supplied to the inside of the first floor, part 1 Air under the floor is supplied to the ceiling of each floor through a duct, and the air supplied to the interior of the ceiling is supplied to the room from the gallery installed in the ceiling of each room. In addition, it has become possible to send cool air, which was weakly chilled, into each room in summer.
Japanese Patent Application No. 2009-158863

  However, even in the invention of Patent Document 3 filed by the present applicant, when the rainy or cloudy day continues, the temperature of the hot water of the solar water heater does not rise, and the temperature difference between the rainy and cloudy day and the sunny day The problem that is large occurred.

In addition, in the case of the geopower system described in Patent Document 4, which has been conventionally known as a building air-conditioning ventilation system that uses a geothermal heat exchanger, in the winter season, only the underground heat alone can produce a heating effect (even underground 5m) The medium temperature is around 18 degrees, so even if the outside air is warmed by underground heat, the temperature is only lower than that), and the price is high. .
JP2007-303693A

Furthermore, in the case of the OM solar described in Patent Document 5, which is known as a solar system using solar energy, an auxiliary heating device is required because the heating effect is reduced when rainy or cloudy days continue. There was a problem, and further, there was a drawback that cold wind operation was not possible in summer.

By operating the blower, the air inside the first floor is underground. It is sucked into the heat recovery pipe, and in the winter, it is heated in the ground heat recovery pipe by the geothermal heat to warm the air inside the first floor floor, and a hot water heat storage tank is installed on the foundation bottom under the first floor. Hot water heated by a solar water heater in a hot water storage tank in a bath After using the hot water, the remaining hot water in the hot water storage tank is allowed to flow into the hot water storage tank, so that the air inside the 1st floor floor is further warmed and becomes a warm air, and the heated air inside the 1st floor floor is By operating the duct blower provided inside the ceiling of each floor, it is sent from the lower floor of the first floor to the interior of the ceiling of each floor via the duct, supplied to the room from the gallery provided on the ceiling, and warms the room. In summer, the remaining hot water of the bath is not supplied to the hot water storage tank, and the outside air sent from the total heat exchange type exhaust fan to the inside of the first floor is cooled by the underground heat and weakened in the underground heat recovery pipe. After being cooled and mixed with the air at the bottom of the first floor, the duct blower provided inside the ceiling of each floor is operated to send it from the bottom of the first floor to the ceiling of each floor via the duct. From the gallery established in It is supplied to the inside and is characterized in that cold room.

  In addition to the structure of Claim 1, the invention described in Claim 2 has a water pillow-like shape composed of rubber-like sheets, and is supplied to the warm water heat storage tank during the winter. The hot water remaining in the hot bath is taken into the upper part of the hot water heat storage tank from the inlet provided on the upper surface of the hot water heat storage tank, and hot water is stored in the hot water heat storage tank to warm the hot water heat storage tank. The drainage outlet for draining water overflowing from the drainage pipe is provided at the bottom of the hot water storage tank, and the drain pipe piping from the drainage inlet is connected to the top of the hot water storage tank from the bottom of the hot water storage tank. The hot water storage tank is piped to the same height as the remaining hot water intake, and the remaining hot water from the cold bath at the bottom of the hot water storage tank is discharged outside the hot water storage tank. .

  In addition to the structure described in claim 1 or 2, the invention described in claim 3 connects hot water heated by a solar water heater to a solar water heater connection unit installed between a water supply and a bath water heater. If the temperature of the hot water heated by the solar water heater is low, the hot water is heated in the bath water heater and hot water is supplied to the bath, and the hot remaining hot water in the bath is poured into the hot water heat storage tank. It is characterized by the fact that it was stored in the water.

  According to the first aspect of the present invention, in the winter season, a ventilation hole is not installed on the foundation of the building, and the air inside the first floor is shut off from the outside air to be in a sealed state. The fresh heat supplied to the indoor side by the installed total heat exchange type exhaust fan is sent to the lower part of the first floor of the building, and a plurality of underground heat recovery pipes that are formed in a U-shaped lower part on the foundation floor under the first floor , Both ends are buried in the ground so that it protrudes from the base floor to the lower part of the first floor, and a blower is attached to one end of the underground heat recovery pipe. It is sucked into the recovery pipe and heated by the underground heat in the underground heat recovery pipe to warm the air inside the floor under the first floor, and after using the hot water from the solar water heater in the bath, it flows into the hot water storage tank In case of rain or cloudy weather It is possible to warm the temperature of the air in the lower floor of the first floor without relying only on underground heat, and it is possible to reuse the energy of the remaining hot water in the hot bath that has been flowing through the drainage channel so far. It became possible to contribute to reduction and energy saving. Also, in summer, the remaining hot water from the bath is not supplied to the hot water storage tank, and the outside air sent from the total heat exchange ventilator to the interior of the first floor is cooled in the underground heat recovery pipe by underground heat. After being mixed with the air at the bottom of the first floor, the duct blower provided inside the ceiling of each floor is operated to send it from the interior of the first floor to the ceiling of each floor via the duct. Since it was supplied indoors from the gallery and cooled the room, it was possible to provide an energy-saving air conditioner with low energy consumption.

  According to the second aspect of the present invention, the hot water heat storage tank has a water-pillar shape composed of rubber-like sheets (sheets such as vinyl chloride sheets) and is supplied to the hot water heat storage tank during the winter season. The hot water remaining in the hot bath is taken into the upper part of the hot water heat storage tank from the inlet provided on the upper surface of the hot water heat storage tank, and hot water is stored in the hot water heat storage tank to warm the hot water heat storage tank. The drainage outlet for draining water that overflows from the drainage pipe is installed at the bottom of the hot water storage tank, and the drain pipe that extends from the drainage inlet is located on the top of the hot water storage tank from the bottom of the hot water storage tank. The hot water storage tank is piped up to the same height as the intake of the remaining hot water, and the remaining hot water at the bottom of the hot water storage tank is discharged to the outside of the hot water storage tank. From the entrance of the remaining bath water on the top The hot remaining hot water is mixed with the remaining hot water of the cold bath in the hot water storage tank, so that the upper part of the hot water storage tank becomes warmer than the lower part of the hot water storage tank. The remaining hot water of the cooled bath is taken in and drained from a drainage inlet provided at the bottom of the hot water storage tank. At this time, the height of the intake of the remaining hot water of the bath attached to the hot water storage tank and the drain outlet discharged from the drain pipe piping is configured to be higher than the position of the upper surface where the hot water storage tank is filled with the remaining hot water. By the fact, in the state where hot water is not put, it becomes possible for the rubber-like bag of Pechanco to keep the hot water heat storage tank in a water pillow shape by putting the remaining hot water of the bath into the hot water heat storage tank. In addition, since the drainage intake port is installed at the bottom of the hot water storage tank, the hot water that accumulates in the bottom of the hot water storage tank, which is contained in the remaining hot water of the bath, is easy with the remaining hot water of the cold bath. Can be discharged. In this way, by making a hot water storage tank using inexpensive rubber sheets (vinyl chloride sheet, etc.), the size (volume) of the hot water storage tank can be easily changed according to the total floor area of the building. Not only became possible, but also shortened the construction period for producing the hot water heat storage tank and made it possible to produce it at a lower cost.

  According to the invention described in claim 3, when hot water heated by a solar water heater is connected to a solar water heater connection unit installed between a water supply and a bath water heater, and a rainy or cloudy day continues If the temperature of the hot water heated by the solar water heater is low, the hot water of the solar water heater is warmed by the bath water heater and hot water is supplied to the bath. It is possible to reuse the energy of the hot water remaining in the hot bath that has been flowing through the drainage drainage so far, saving CO2 and saving energy. I was able to contribute.

Embodiment 1 of the present invention will be described below.
Embodiment 1 of the Invention

   1 to 7 show an embodiment of the present invention.

  FIG. 1 is an exploded explanatory view of a 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 house 1 incorporating an improved earth / solar system (geothermal recovery pipe method) in order to explain the improved earth / solar system (geothermal recovery pipe method) of the present invention. It is shown in the figure. In addition to installing the solar water heater 2 on the roof 3, the foundation 29 is not provided with the outside of the building and vents, and outside the foundation 29, heat from outside air is not easily transferred to the inside of the floor under the first floor. In addition to the construction of the material 6, a hot water heat storage tank 44 is installed at the center of the foundation bottom board 45, and a remaining hot water pipe 38 for supplying the remaining hot water of the bath 34 is provided in the hot water heat storage tank 44. Further, at the four corners of the foundation bottom plate 45, there are four underground heat recovery pipes 13, a ground heat recovery pipe 20, a ground heat recovery pipe 23, and a ground heat recovery pipe 26, each having a U-shaped lower portion. Is buried in the ground so as to protrude from the base bottom 45 to the lower part of the first floor.

  In the earth / solar system improved type (ground heat recovery pipe method) configured in this way, hot water heated by the solar water heater 2 is supplied to the bath 34 via the hot water pipe 40, and further in the bath 34. The hot remaining hot water after being used is removed from the drain plug (not shown) attached to the bathtub for the remaining hot water pipe 38 provided in the bath 34, so that the hot water heat storage tank passes through the remaining hot water pipe 38. The hot water is stored at 44. Further, the heat insulating material 6 outside the foundation is applied to the outside of the foundation 29, and the four ground heat recovery pipes 13, the underground heat recovery pipes 20, and the underground heat recovery pipes are provided on the foundation bottom plate 45 inside the foundation 29. 23, while the underground heat recovery pipe 26 is installed, the indoor side supply air (fresh air) exchanged by the total heat exchange type ventilation fan 4 attached to the living room is indicated by an arrow through the outside air introduction duct 5 It is sent in 7 directions and is supplied to the interior under the first floor.

  The geothermal heat recovery pipe 13, the geothermal heat recovery pipe 20, the geothermal heat recovery pipe 23, and the geothermal heat recovery pipe 26 are configured such that the lower part of the two PVC pipes is joined by a joint and the lower part is formed in a U shape. The joints such as L-shaped elbows are attached to the parts of the two PVC pipes protruding from the top of the foundation bottom 45 at the four corners of the foundation bottom 45, and the air intake such as L-shaped elbows attached to the two PVC pipes The inlet and the air outlet are configured to be at right angles to each other, and a blower is attached to the tip of one elbow or the like. In order to form the above-described polyvinyl chloride pipe into a U shape as a ground heat recovery pipe, the lower portions of the polyvinyl chloride pipe 48 and the polyvinyl chloride pipe 49 are joined by a U-shaped joint 50 as shown in the enlarged view of FIG. As a result, it becomes a single underground heat recovery pipe.

  Furthermore, as shown in FIGS. 1 and 5, by operating the blower 10, the blower 17, the blower 35, and the blower 42, the air inside the first floor under the ground heat recovery pipe 8 sucked from the arrow 133 direction is 1 flows from the direction of arrow 12 to the direction of arrow 14 through the underground heat recovery pipe 13 in FIG. Is done. The air discharged into the first floor under the air in this way is blown in the direction of arrow 11, mixed with the air inside the first floor under the air, adjusted in temperature, and sucked into the underground heat recovery pipe 15 again from the direction of arrow 130. Then, the temperature of the underground heat recovery pipe 20 flows from the direction of the arrow 19 to the direction of the arrow 21 and is adjusted by the underground heat, and is discharged from the blower 17 to the inside of the first floor under the ground heat recovery pipe 16. The In this way, the air discharged to the inside of the first floor is blown in the direction of the arrow 18, mixed with the air inside the first floor, the temperature is adjusted, and again sucked into the underground heat recovery pipe 30 from the direction of the arrow 131. Then, the temperature of the ground heat recovery pipe 26 flows from the direction of the arrow 27 to the direction of the arrow 25 and the temperature is adjusted by the ground heat, and is discharged from the blower 35 to the inside of the first floor under the ground heat recovery pipe 31. The The air discharged into the first floor under the air in this way is blown in the direction of the arrow 36, mixed with the air inside the first floor under the air, adjusted in temperature, and sucked into the underground heat recovery pipe 39 again from the direction of the arrow 132. Then, the temperature of the ground heat recovery pipe 23 flows from the direction of the arrow 24 to the direction of the arrow 22 and is adjusted by the ground heat, and is discharged from the blower 42 to the inside of the first floor under the ground heat recovery pipe 41. The The air thus exhausted is blown in the direction of arrow 43, mixed with the air inside the first floor, adjusted for temperature, and sucked into the underground heat recovery pipe 8 again from the direction of arrow 133. As described above, the air intake ports (ground heat recovery pipes) of the ground heat recovery pipe 13, the ground heat recovery pipe 20, the ground heat recovery pipe 23, and the ground heat recovery pipe 26 arranged at the four corners of the foundation bottom 45 are described. 8, the geothermal heat recovery pipe 15, the geothermal heat recovery pipe 30, the geothermal heat recovery pipe 39), and the air outlet of the geothermal heat recovery pipe (the geothermal heat recovery pipe 9, the geothermal heat recovery pipe 16, By configuring the underground heat recovery pipe 31 and the underground heat recovery pipe 41) to face each other, the air inside the first floor does not stagnate depending on the location inside the floor, and the temperature of the air inside the first floor Is adjusted to a uniform temperature.

  In addition, the underground heat recovery pipe 13, the underground heat recovery pipe 20, the underground heat recovery pipe 23, and the underground heat recovery pipe 26 are embedded in the four corners of the foundation floor 45 under the first floor, so that the underground It becomes possible to reduce the interference of heat from each other's underground heat recovery pipes due to heat generated from the heat recovery pipes. In particular, when a large number of underground heat recovery pipes are embedded in a narrow site, the underground temperature changes due to the underground heat interference between the underground heat recovery pipes, and the merit of the underground heat recovery is reduced.

  As described above, the ground heat recovery pipe 13, the ground heat recovery pipe 20, the ground heat recovery pipe 23, and the ground heat recovery pipe 26 are each attached with one blower to recover the ground heat. It became possible to recover the geothermal heat efficiently. Furthermore, the temperature of the air inside the floor under the first floor is obtained by independently attaching a blower to each of the underground heat recovery pipe 13, the underground heat recovery pipe 20, the underground heat recovery pipe 23, and the underground heat recovery pipe 26. However, if it is too cold (warm) in the early days of summer (winter), move only a few of the four geothermal heat recovery pipes and stop the operation of the other geothermal heat recovery pipes. It is possible to adjust the temperature inside the first floor floor.

  In the present invention, a PVC pipe is used for the underground heat recovery pipe 13, the underground heat recovery pipe 20, the underground heat recovery pipe 23, and the underground heat recovery pipe 26, and the depth embedded in the underground is about 5 meters. is there. The reason is that the underground temperature of 4-5 meters underground in the Kanto district is about 17 ° C-19 ° C throughout the year with little change in temperature. By the way, our showroom (with basement) in Adachi-ku, Tokyo measures the underground temperature of 1 meter, 3 meters, and 5 meters every day. According to the measurement results, it is 5 meters underground. The middle temperature is the lowest temperature of 17.1 ° C between May and June and the highest temperature of 19.3 ° C between November and December. The reason why the minimum temperature of 5 meters underground is from May to June with respect to the lowest outside air temperature (around February) is because it takes time for the surface temperature to penetrate into the ground. The same is true for summer.

  Furthermore, when the underground heat recovery pipe is buried in the ground, an auger is attached to a small heavy machine (building pillar, etc.), a hole is dug in the ground with the auger, and the underground heat recovery pipe is embedded in the hole. The construction period can be shortened and construction can be performed at low cost.

  In addition, in the foundation part under the first floor of a general house, in particular, the cloth foundation has a structure in which ventilation is good in order 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 temperature. In order to use as an adjustment tank, it is constructed so that the lower part of the first floor is configured in a sealed state so that outside air does not directly flow 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 air supplied to the indoor side from the total heat exchange type ventilation fan 54 and the total heat exchange type ventilation fan 55 to the lower floor 96 will be described. The room-side discharged air (contaminated room air) in the first floor room A is sucked into the total heat exchange type ventilation fan 55 and exhausted outside the room. At that time, the indoor air exhausted by the total heat exchanging ventilation fan 55 (indoor discharge air) and the outside air supplied to the room (outdoor intake air) are heat-exchanged inside the total heat exchanging fan 55. At the same time, all of the sucked outdoor outside intake air (fresh air) is guided to the first floor under floor 96 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 ventilation fan 54 and exhausted to the outside. At that time, the indoor air exhausted by the total heat exchange type ventilation fan 54 (indoor discharge air) and the outside air supplied to the room (outdoor intake air) are heat-exchanged in the total heat exchange type ventilation fan 54. At the same time, all of the sucked outdoor outside intake air (fresh air) is guided to the first floor under floor 96 via the outside air introduction duct 57.

  In this way, by using the total heat exchange type ventilation fan 54 and the total heat exchange type ventilation fan 55, when the cool indoor air in the summer is replaced (ventilated) with the hot outdoor air, the cool indoor air It is possible to minimize the temperature rise.

  Subsequently, how the outside air (outside air sucked in) from the total heat exchange type ventilation fan 54 and the total heat exchange type ventilation fan 55 introduced into the first floor under floor 96 in this way exchanges heat in the first floor under floor 96. Explain how the wind will be weak. The outside air introduced from the outside air introduction duct 56 and the outside air introduction duct 57 from the total heat exchange type ventilation fan 54 and the total heat exchange type ventilation fan 55 is mixed with the air under the first floor 96 and attached to the underground heat recovery pipe 64. By operating the blower 61, the air under the first floor 96 is sucked into the underground heat recovery pipe 64 from the direction of the arrow 60, and is cooled by the underground heat in the underground heat recovery pipe 64, so that the slightly cold air Then, the air is exhausted from the blower 61 to the lower first floor 96 as shown in the direction of the arrow 62. Similarly, by operating the blower 66 attached to the underground heat recovery pipe 68, the air under the first floor 96 is sucked into the underground heat recovery pipe 68 from the direction of the arrow 65, and the ground heat recovery pipe 68 It is cooled by underground heat and becomes weak cold air, and is exhausted from the blower 66 to the lower first floor 96 as indicated by an arrow 67 direction. Similarly, by operating the blower 71 attached to the underground heat recovery pipe 69, the air in the first floor lower floor 96 is sucked into the underground heat recovery pipe 69 from the direction of the arrow 70, and the underground heat recovery pipe 69 It is cooled by underground heat and becomes weak cold air, and is exhausted from the blower 71 to the lower first floor 96 as indicated by the arrow 72 direction. Similarly, by operating the blower 75 attached to the underground heat recovery pipe 74, the air under the first floor 96 is sucked into the underground heat recovery pipe 74 from the direction of the arrow 73, and the ground heat recovery pipe 74 It is cooled by underground heat and becomes weak cold air, and is exhausted from the blower 75 to the lower first floor 96 as indicated by the arrow 76 direction.

  In this way, the outside air that has become weak air in the first floor under floor 96 cools the first floor room A by cooling the first floor, and the air in the first floor under floor 96 that has become weak air is supplied as air. By operating the blower 104 attached to the duct 88, air is supplied to the first floor ceiling 100 via the air supply duct 88, and is supplied to the first floor room A from the gallery 98 and the gallery 102, thereby being supplied to the first floor room. Cool A. Similarly, by operating the air blower 112 attached to the air supply duct 105, the outside air that has become weak air in the first floor under floor 96 is supplied to the second floor ceiling 107 through the air supply duct 105. Then, the second floor room B is supplied from the gallery 109 and the gallery 110 to cool the second floor room B.

  In the summer, the remaining hot water of the bath 92 is not supplied to the hot water heat storage tank 94 installed under the first floor floor 96, and the hot water heat storage tank 94 is not used in the summer.

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

  First, a method for supplying air supplied to the indoor side from the total heat exchange type ventilation fan 54 and the total heat exchange type ventilation fan 55 to the lower floor 96 will be described. The room-side discharged air (contaminated room air) in the first floor room A is sucked into the total heat exchange type ventilation fan 55 and exhausted outside the room. At that time, the indoor air exhausted by the total heat exchange type ventilation fan 55 (indoor discharge air) and the outside air supplied to the room (outdoor intake air) are heat-exchanged in the total heat exchange type ventilation fan 55. At the same time, all of the sucked outdoor outside intake air (fresh air) is guided to the first floor under floor 96 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 ventilation fan 54 and exhausted to the outside. At that time, the indoor air exhausted by the total heat exchange type ventilation fan 54 (indoor discharge air) and the outside air supplied to the room (outdoor intake air) are heat-exchanged in the total heat exchange type ventilation fan 54. At the same time, all of the sucked outdoor outside intake air (fresh air) is guided to the first floor under floor 96 via the outside air introduction duct 57.

  In this way, by using the total heat exchange type ventilation fan 54 and the total heat exchange type ventilation fan 55, when the indoor warm air in the winter is replaced (ventilated) with the cold outdoor air, It is possible to minimize the temperature drop. By the way, on the Mitsubishi Electric Corporation homepage, the heat exchange function of LOSSNAY (total heat exchange type exhaust fan) is “when the outside air temperature is 0 ° C., the room temperature is 20 ° C., and the temperature exchange efficiency is 75%”. When the air is ventilated with LOSSNAY (total heat exchange type exhaust fan), the temperature of the air of the outside air (0 ° C.) becomes 15 ° C. due to the action of the heat exchanger and is supplied to the room (fresh air).

  Subsequently, how the outside air (outside air sucked in) from the total heat exchange type ventilation fan 54 and the total heat exchange type ventilation fan 55 introduced into the first floor under floor 96 in this way exchanges heat in the first floor under floor 96. Explain how the wind becomes weak. The outside air introduced from the outside air introduction duct 56, the total heat exchange type ventilation fan 54 and the total heat exchange type ventilation fan 55 introduced from the outside air introduction duct 57 is mixed with the air under the first floor 96 and attached to the underground heat recovery pipe 64. By operating the blower 61, the air under the first floor 96 is sucked into the underground heat recovery pipe 64 from the direction of the arrow 60, and is warmed by the underground heat in the underground heat recovery pipe 64, so that the warm air Then, the air is exhausted from the blower 61 to the lower first floor 96 as shown in the direction of the arrow 62. Similarly, by operating the blower 66 attached to the underground heat recovery pipe 68, the air under the first floor 96 is sucked into the underground heat recovery pipe 68 from the direction of the arrow 65, and the ground heat recovery pipe 68 Inside, it is warmed by underground heat to become weakly warm air, and is exhausted from the blower 66 to the lower first floor 96 as indicated by the arrow 67 direction. Similarly, by operating the blower 71 attached to the underground heat recovery pipe 69, the air in the first floor lower floor 96 is sucked into the underground heat recovery pipe 69 from the direction of the arrow 70, and the underground heat recovery pipe 69 Inside, it is warmed by underground heat to become weakly warm air, and is exhausted from the blower 71 to the lower first floor 96 as indicated by the arrow 72 direction. Similarly, by operating the blower 75 attached to the underground heat recovery pipe 74, the air under the first floor 96 is sucked into the underground heat recovery pipe 74 from the direction of the arrow 73, and the ground heat recovery pipe 74 Inside, it is warmed by underground heat to become weakly warm air, and is exhausted from the blower 75 to the lower first floor 96 as indicated by the arrow 76 direction.

  Further, in the winter season, after the hot water heated by the solar water heater 115 is used in the bath 92, the hot remaining hot water after being used in the bath 92 is a drain plug for the remaining hot water pipe 93 provided in the bath 92 (see FIG. (Not shown), the hot water is stored in the hot water storage tank 94 via the remaining hot water pipe 93. The remaining hot water in the warm bath 92 stored in the hot water heat storage tank 94 in this manner warms the air under the first floor 96. In addition, the remaining hot water in the bath that has overflowed from the hot water heat storage tank 94 and is cooled at the bottom of the hot water heat storage tank 94 flows through the drain pipe 77 in the direction of arrow 119 and is drained into the drain groove 78.

  In this way, the hot water heated by the solar water heater 115 is used in the bath 92 and then used in the bath 92, and the hot remaining hot water after being used in the bath 92 is placed in the hot water heat storage tank 94 installed on the foundation bottom of the first floor floor 96. The underground heat recovery pipe 64, the geothermal heat recovery pipe 68, the geothermal heat recovery pipe 69, and the geothermal heat recovery pipe 74 are heated by the geothermal heat, thereby allowing the ground heat recovery pipe 64, the geothermal heat recovery pipe 68, The air is further warmed by the hot water heat storage tank 94.

  In this way, the outside air that has become low-temperature air in the first floor under 96 warms the first-floor room A by heating the first floor, and the air in the first-floor under 96 that has become low-temperature air is supplied as air. By operating the blower 104 attached to the duct 88, air is supplied to the first floor ceiling 100 via the air supply duct 88, and is supplied to the first floor room A from the gallery 98 and the gallery 102, thereby being supplied to the first floor room. Warm up. Similarly, by operating the air blower 112 attached to the air supply duct 105, the air is supplied to the second floor ceiling 107 through the air supply duct 105, and is supplied to the second floor room B from the gallery 109 and the gallery 110. The room B on the second floor is warmed.

  In this way, in the winter season, hot water heated by the solar water heater 115 is used in the bath 92, and the hot remaining hot water after being used in the bath 92 is installed in the base floor of the first floor floor 96 under the hot water heat storage. Even if it is cloudy or rainy, the hot water remaining after being used in the bath 92 is poured into the hot water storage tank 94 to store hot water. The air under the first floor 96 warmed by the underground heat in the recovery pipe 64, the underground heat recovery pipe 68, the underground heat recovery pipe 69, and the underground heat recovery pipe 74 is further heated to 1 as a warm air. It is possible to supply air to the floor room A and the second floor room B.

  FIG. 4 shows a state in which the house 52 in the present invention is configured by next-generation energy-saving heat insulation. Regarding the heat insulation of the roof, the roof heat insulating material 121 (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, the outer wall heat insulating material 122 (generally, urethane foam having a thickness of 75 mm) is applied to the inside of the outer wall. As for the window sash, a heat insulation sash 123 of heat insulation grade 4 (next generation energy saving type) sold by each company is used. With respect to the heat insulation of the foundation, an outside foundation heat insulating material 124 (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 polystyrene plate, the heat insulating effect changes due to the difference in density, so even the same manufacturer changes the thickness depending on the density There may be cases. In the next-generation energy-saving type housing, heat insulating material is installed under the first floor, under the first floor, and under the second floor. In the present invention, the temperature in each room of the house is as uniform as possible. Therefore, no heat insulating material is applied to the first floor under floor 126, the first floor ceiling 125, and the second floor ceiling 127.

  Regarding the heat insulation performance of the house 52 in the present invention, the next-generation energy-saving type heat insulation described with reference to FIG.

  FIG. 6 is a front view, a plan view, an AA cross-sectional view, and a BB cross-sectional view of the hot water heat storage tank 152. The hot water heat storage tank 152 is configured in a water pillow shape by welding the ends of two rubber-like sheets (vinyl chloride sheet or the like) cut into a rectangle. The upper surface rubber sheet 139 used in the upper part of the hot water heat storage tank 152 is provided with holes (not shown) for the intake port 134 and the drain port 135, and the rubber sheet is cut into a square shape (about 20 cm × about 25 cm). In the center, a hole (not shown) for the remaining hot water in the bath is opened to create a welded portion 137, and the welded portion 137 has an inlet 134 made of a PVC pipe. Similarly, the rubber sheet is cut into a square shape (about 20 cm × about 25 cm in size), and a hole (not shown) for a drain outlet is formed in the center to weld the portion 138. The drainage port 135 made of a PVC pipe is welded to the welded portion 138 by vinyl chloride welding, and the welded portion 137 and the welded portion 138 are welded in accordance with a hole position (not shown) formed in the upper rubber sheet 139. And install. Currently, when building an artificial lake in the desert, etc., a large hole is dug in the desert, and a rubber sheet (vinyl chloride sheet, etc.) is laid on the bottom of the hole, and the rubber sheets are welded together to form a large sheet. Processing into a waterproof sheet to store water is also performed, and long-term durability is maintained even when a hot water heat storage tank like the present invention is made of a rubber sheet.

  When the remaining hot water of the bath flows into the hot water storage tank interior 151 from the inlet 134 attached in this way, the remaining hot water of the bath flows from the inlet 134 to the welded portion 137 as shown in the BB cross-sectional view. As shown by the direction of the arrow 146 through the fixing portion 147 attached immediately below the hot water storage tank 151, the hot water remaining in the hot bath is stored on the upper side of the hot water storage tank 151. When the remaining hot water is supplied to the hot water heat storage tank interior 151 in this way, the upper part of the hot water heat storage tank interior 151 is kept warm, and the lower part of the hot water heat storage tank internal 151 is in a state where the hot water temperature is lower than the upper part.

  Moreover, the remaining hot water of the cooled bath drained from the hot water storage tank interior 151 is sucked in the direction of the arrow 148 from the drain intake port 149 at the lower part of the hot water storage tank interior 151, as shown in the AA sectional view. The water is drained from the drain port 135 via the drain pipe pipe 151. In addition, the height of the inlet 134 of the inlet 134 attached to the hot water heat storage tank 152 into which the remaining hot water of the bath flows, and the height of the outlet 135 of the drain outlet from which the remaining hot water of the bath is discharged from the hot water heat storage tank 152 are Since the heat storage tank 152 is made of a rubber-like sheet, when the remaining hot water in the bath flows into the hot water heat storage tank 152, the hot water heat storage tank 152 swells in the shape of a water pillow. In the state where it is introduced until it reaches a full tank state, it is above the uppermost part of the upper surface rubber sheet 139 of the hot water heat storage tank 152 (may be about 10 to about 20 cm higher than the upper part of the upper surface rubber sheet 139). Must be configured as follows.

  By configuring the hot water heat storage tank 152 in this way, the hot water remaining in the hot bath is supplied to the hot water heat storage tank 152 every day, and even if rain or cloudy days continue, it is possible to warm the air in the lower floor of the first floor It becomes. Furthermore, since the drainage inlet 149 is installed at the bottom of the hot water storage tank interior 151, the hot water accumulated in the bottom of the hot water storage tank interior 151 contained in the remaining hot water of the bath is replaced with the remaining hot water of the cooled bath. It can be easily discharged together.

  FIG. 7 shows how the hot water storage tank described in FIG. 6 is installed under the first floor. The hot water heat storage tank 158 is installed on the upper surface of the foundation 164 under the first floor, and a drain plug (not shown) for the hot water heat storage tank installed in the bath 154 is pulled out of the hot water heat storage tank 158. As a result, the remaining hot water of the bath 154 is sent in the direction of the arrow 157 via the remaining hot water pipe 155 and stored in the hot water heat storage tank 158, and the remaining hot water of the cooled bath overflowing from the hot water heat storage tank 158 is The water is drained from the direction of the arrow 163 to the drain groove 162 via the drain pipe 161.

The second embodiment of the present invention will be described below.
[Embodiment 2 of the Invention]

  FIG. 8 is a cross-sectional view when the solar water heater connection unit 172 is connected to the solar water heater 166. The water sent from the water supply pipe 178 to the arrow 169 direction from the arrow 176 direction is warmed in the solar water heater 166. The hot water heated in the solar water heater 166 is sent from the direction of the arrow 167 to the direction of the arrow 170 through the hot water pipe 171 and mixed with the water supplied from the water supply pipe 178 in the solar water heater connection unit 172. The temperature is adjusted, and the temperature is adjusted in the bath water heater 174 to supply hot water to the bath.

  The merit of using the solar water heater connection unit 172 is that, when a rainy or cloudy day continues, when the temperature of the solar water heater 166 does not reach the appropriate temperature of the hot water of the bath, the hot water of the solar water heater 166 is the bath water heater 174. It can be heated and supplied to the bath. These solar water heater connection units 172 are sold by companies such as Noritz Corporation, Rinnai Corporation, and Chofu Seisakusho Co., Ltd. Other details of the structure of the total heat exchange type exhaust fan, the hot water heat storage tank installed under the first floor, the underground heat recovery pipe, and the air supply duct are the same as those described in the first embodiment.

  As mentioned above, based on the embodiment, the earth / solar system improved type (ground heat recovery pipe system) according to the present invention has been described in detail. However, the present invention is not limited to the above embodiment. Of course, various modifications within the scope of the invention do not fall within the technical scope of the present invention.

  1 and 5, the shape of the hot water heat storage tank 44 (represented as the hot water heat storage tank 44 in FIG. 1 and the hot water heat storage tank 94 in FIG. 5) for storing the hot water from the solar water heater 2 is a cube. However, the hot water heat storage tank is not limited to this shape by connecting a long PVC pipe or a rib pipe that can be easily bent between the remaining hot water pipe 38 and the drain pipe 37. It is also possible to configure. By constructing the hot water heat storage tank using such a material, even when the foundation under the first floor is complicated, the hot water heat storage tank can be easily constructed. In addition, regarding the material of the hot water storage tank, in the embodiment of the present invention, it is rubber-like in order to produce it at a low cost. However, in consideration of long-term durability, the thermal storage tank made of FRP, and further, stainless steel Of course, it is also possible to construct a thermal storage tank with such a metal.

  In FIG. 1, the hot water heat storage tank 44 is installed on the upper part of the foundation bottom board 45, but when installing the hot water heat storage tank 44, the foundation bottom board 45 is cut out and the hot water heat storage tank 44 is embedded in the base water board 44. Alternatively, it is of course possible to provide an enclosure at the base bottom plate 45 where the hot water heat storage tank 44 is installed, and to install the hot water heat storage tank 44 therein. Furthermore, although the hot water heat storage tank 44 is drawn with one piece, when the foundation under the first floor is configured in a complicated manner, it is possible to connect a plurality of hot water heat storage tanks. In addition, since many new homes have been newly built recently, it is important to design the size of the hot water storage tank according to the number of baths.

  1 and 5, the underground heat recovery pipes 13, 20, 23, and 26 are arranged at the four corners of the foundation bottom 45, and this is because each other's underground heat recovery pipe recovers the underground heat ( This is because the influence of the heat applied to the ground when the heat is recovered (heat released) by the underground heat recovery pipe is less likely to interfere with each other's underground heat recovery pipe.

  1 to 5, four geothermal heat recovery pipes are installed, but the number of geothermal heat recovery pipes increases or decreases depending on the size of the house (floor area). In addition, since the underground heat capacity changes depending on the underground water level, it is of course possible to use materials such as aluminum and stainless steel with high thermal conductivity.

  In the present invention, a PVC pipe is used as the underground heat recovery pipe, and the depth embedded in the underground is about 5 m. Of course, it is of course necessary to change the depth of the PVC pipe embedded in the ground, depending on the groundwater level in the ground.

  1 to 3, the solar water heater denoted as solar water heater 2 in FIG. 1 and the solar water heater 115 in FIGS. 2 and 3 is formed by integrating a solar heat collecting plate and a hot water tank. Although it was explained in the form of becoming, it is not limited to this form, the solar heat collecting plate and the hot water tank are separated, the solar heat collecting plate is installed on the roof, and the hot water tank is fixed to the ground surface It is also possible to use a solar water heater of the type specified.

  2 to 3, the piping space for the outside air introduction ducts 56 and 57 and the air supply ducts 88 and 105 is not limited to the interior 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 general house, it is natural that the type of house to be constructed can be applied to a steel frame house, an RC concrete house, and the like.
