The temperature-conditioned air is supplied to the inside of a ceiling of each story through an air supply duct, and further supplied indoors from louvers disposed on the ceilings.

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 the winter season, and a hot water storage tank is installed in the foundation floor under the first floor, and the hot water boiled in eco-cute water in the hot water storage tank After using the bath, leave a 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, since the underground of 4 to 5 meters below the ground maintains a stable temperature throughout the year, 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, in the heat pump system using geothermal heat, there is also a method of domestic hot water supply and indoor air conditioning, but the horizontal loop method (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 400-600 meter heat collecting pipe, and a vertical loop system. (To dig a well of 50-100 meters deep in the ground and embed a pipe for heat collection there) requires two wells, and costs 3 to 5 million yen for general housing, There is a problem that the operating cost (electricity cost) of the heat pump is 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 has 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, a concrete tank composed of the foundation and the body of the building is constructed in the lower part of the building, the heat exchange pipe is piped in the concrete tank, and the rainwater is put inside the concrete tank. Or, it is filled with tap water or groundwater, and the supply air from the total heat exchange type ventilation fan is led to the heat exchange pipe in the concrete tank, and in summer, the supply air from the total heat exchange type ventilation fan is cooled by underground heat. After heat exchange between the water in the made concrete tank and the heat exchange pipe, it is cooled and then supplied to each floor via the air supply pipe. In the winter, hot water from the solar water heater is supplied to the concrete. Circulate in the tank made of concrete, bring the inside of the concrete tank to a warm water state, lead the supply air from the total heat exchange type exhaust fan to the heat exchange pipe in the concrete tank, and warm water 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 inside, and a blower is attached to one end of the underground heat recovery pipe. By operating the blower, the air inside the floor under the first floor is sucked into the underground heat recovery pipe, 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, During the season, the hot water from the solar water heater is not circulated in the hot water storage tank provided at the bottom of the first floor, but the air cooled by the underground heat recovery pipe is supplied to the inside of the first floor under the ground heat. By supplying the air inside the floor under the first floor through the duct to the ceiling of each floor, and the air supplied inside the ceiling from the gallery installed in the ceiling of each room, the warm air that has been slightly heated in winter In addition to supplying to each room, it became possible to send cool air, which was weakly cooled in the summer, to each room.
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.

Therefore, the present applicant invented and applied for the “earth / solar system improved type (ground heat recovery pipe system)” described in Patent Document 4. According to this invention, in winter, the remaining hot water of the bath is poured into a hot water heat storage tank provided at the lower part of the first floor to store hot water, and rubber or the like (vinyl chloride sheet or the like) is used to reduce the cost of the hot water heat storage tank. Because it is made of cheap materials, it is possible to store hot water in the hot water heat storage tank even when rainy or cloudy days continue, and supply warm air that is slightly heated in winter to each room In summer, hot water from the solar water heater is not circulated in the hot water storage tank installed at the bottom of the 1st floor, and the air cooled in the underground heat recovery pipe is supplied to the interior of the 1st floor under the ground heat. Then, the air under the floor of the first floor is supplied to the inside of the ceiling of each floor through the duct, and it is possible to send the cool air, which is supplied into the ceiling, into the rooms.

  However, even in the invention of Patent Document 4 filed by the present applicant, in order to supply warm hot water to the hot water heat storage tank in the winter, basically the hot water of the solar water heater is used, and rainy or cloudy days are present. In the case that it continued, hot water from the water heater was used, so when rainy or cloudy days continued, gas charges (electricity charges) to supply hot water to the bath, daily life, toilets and The problem remains that it is expensive to use hot water in the kitchen.

In addition, in the case of the geopower system described in Patent Document 5, 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 5 m) 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 6, which is known as a solar system that uses solar energy, the heating effect is reduced when a rainy or cloudy day continues, so an auxiliary heating device is required. There was a problem, and further, there was a drawback that cold wind operation was not possible in summer.

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

  1 to 10 show a first embodiment of the present invention.

  FIG. 1 is an exploded explanatory view of a house using a solar cell panel, a natural refrigerant heat pump water heater (EcoCute), a total heat exchange type exhaust fan, a hot water heat storage tank, and an underground heat recovery pipe of the present invention. Below, the air conditioning system using sunlight and underground heat is demonstrated.

  FIG. 1 is an exploded explanatory view showing a house 1 incorporating an earth, solar, and zero energy house in order to easily explain the earth, solar, and zero energy house of the present invention. The solar panel 3 is installed on the top of the roof 2, and the natural refrigerant heat pump water heater (EcoCute) 54 is operated by electricity generated by the solar panel 3 to store hot water in the hot water storage tank 50. A hot water storage tank 38 is installed in the center of the foundation bottom plate 52 so that air outside the building does not flow in, and the remaining hot water of the bath 43 is supplied to the hot water storage tank 38. A remaining hot water pipe 37 is provided. Further, at the four corners of the foundation bottom plate 52, there are four underground heat recovery pipes 13, a ground heat recovery pipe 17, a ground heat recovery pipe 23, and a ground heat recovery pipe 28, which are formed in a U shape at the bottom. Is buried in the ground so as to protrude from the base bottom 52 to the lower part of the first floor.

  The earth / solar / zero-energy house constructed in this manner uses the electricity generated by the solar panel 3 to operate the natural refrigerant heat pump water heater (EcoCute) 54 to store hot water in the hot water storage tank 50 and also to store the hot water storage tank. The hot remaining hot water after being used in the bath 43 via a hot water supply pipe 48 from the hot water supply pipe 50 is connected to a drain plug (not shown) for the remaining hot water pipe 37 provided in the bath 43. By extracting, the hot water is stored in the hot water heat storage tank 38 via the remaining hot water pipe 37. In addition, at the four corners of the foundation bottom 52 inside the foundation 25, four geothermal heat recovery pipes 13, a geothermal heat recovery pipe 17, a geothermal heat recovery pipe 23, and a geothermal heat recovery whose lower part is formed in a U shape. While the pipe 28 is installed, the indoor side supply air (fresh air) heat-exchanged by the total heat exchange type ventilation fan 4 attached to the living room is sent in the direction of arrow 7 via the air supply introduction duct 5. The air is supplied to the interior under the first floor.

  The geothermal heat recovery pipe 13, the geothermal heat recovery pipe 17, the geothermal heat recovery pipe 23, and the geothermal heat recovery pipe 28 are joined by connecting the lower parts of two PVC pipes having a diameter of about 100 to 120 mm with joints, The lower part is configured in a U-shape, installed at the four corners of the foundation bottom 52, and two PVC pipes protruding from the upper part of the foundation bottom 52 are fitted with joints such as L-shaped elbows and attached to the two PVC pipes. The L-shaped elbow and other air intakes and air discharge ports are configured to be at right angles to the surface of the foundation base 52, and a blower (24-hour ventilation system exhaust fan) is attached to the tip of one of the elbows. Install. In order to shape the PVC pipe described above into a U-shape as a ground heat recovery pipe, the lower part of the PVC pipe 119 and the PVC pipe 120 is joined by a U-shaped joint 121 as shown in the enlarged view of FIG. As a result, it becomes a single underground heat recovery pipe.

  In the present invention, a PVC pipe is used for the underground heat recovery pipe 13, the underground heat recovery pipe 17, the underground heat recovery pipe 23, and the underground heat recovery pipe 28, 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. In addition, as a construction method to embed the underground heat recovery pipe in the ground, there is a construction method in which an auger is attached to the drilling shaft to dig a digging hole in the ground, and the underground heat recovery pipe is embedded in the hole. It is an inexpensive construction method that can shorten the construction period. The biggest reason for using a digging pillar car and an auger is that the diameter of the digging hole is about 45 centimeters at maximum. Since the excavation depth is about 5 meters, it is suitable for the work to embed the underground heat recovery pipe of the present invention in the ground, and moreover, it is possible to rent the excavated pillar car and the auger easily at low cost. This is because there are advantages. 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 reason why the highest temperature in summer is from November to December is because it takes time for the surface temperature to penetrate into the ground.

  Further, as shown in FIGS. 1 and 4, by operating the blower 10, the blower 20, the blower 35, and the blower 40 that are used in the exhaust fan for the 24-hour ventilation system, the underground heat recovery pipe 8 is moved to the arrow 143. The air inside the first floor under the air sucked from the direction flows in the underground heat recovery pipe 13 in FIG. 1 from the direction of the arrow 12 to the direction of the arrow 14 and is adjusted in temperature by the underground heat. Via, it is discharged from the blower 10 to the inside of the floor under the first floor. In this way, the air discharged into the first floor under the air is blown in the direction of the arrow 11 and mixed with the air inside the first floor under the temperature to adjust the temperature. As shown in FIG. It is sucked into the intermediate heat recovery pipe 15, flows through the underground heat recovery pipe 17 from the direction of the arrow 16 in the direction of the arrow 18, and is adjusted in temperature by underground heat, and from the blower 20 via the underground heat recovery pipe 19 It is discharged inside the floor under the first floor. In this way, the air discharged into the first floor under the air is blown in the direction of the arrow 21 and mixed with the air inside the first floor under the temperature to adjust the temperature. As shown in FIG. The air is sucked into the intermediate heat recovery pipe 30, flows through the underground heat recovery pipe 28 from the direction of the arrow 29 to the direction of the arrow 27, and is adjusted in temperature by the underground heat, and from the blower 35 via the underground heat recovery pipe 33. It is discharged inside the floor under the first floor. The air discharged into the first floor under the air in this way is blown in the direction of the arrow 36 and mixed with the air inside the first floor under the air to adjust the temperature. As shown in FIG. The air is sucked into the intermediate heat recovery pipe 42, flows in the underground heat recovery pipe 23 from the direction of the arrow 24 to the direction of the arrow 22, is adjusted in temperature by the underground heat, and passes through the underground heat recovery pipe 41 from the blower 40. It is discharged inside the floor under the first floor. The air discharged in this way is blown in the direction of arrow 39, mixed with the air inside the first floor, and the temperature is adjusted. As shown in FIG. Sucked into. In this way, the air inlets (geothermal recovery pipes) of the geothermal heat recovery pipe 13, the geothermal heat recovery pipe 17, the geothermal heat recovery pipe 23, and the geothermal heat recovery pipe 28 arranged at the four corners of the foundation bottom plate 52 are provided. 8, the geothermal heat recovery pipe 15, the geothermal heat recovery pipe 30, the geothermal heat recovery pipe 42) and the air outlet of the geothermal heat recovery pipe (the geothermal heat recovery pipe 9, the geothermal heat recovery pipe 19, By configuring the ground heat recovery pipe 33 and the ground heat recovery pipe 41) to face each other, the air inside the first floor floor does not stagnate depending on the location inside the floor, and the temperature of the air inside the first floor floor Is adjusted to a uniform temperature.

  Moreover, it is possible to embed the geothermal heat recovery pipe 13, the geothermal heat recovery pipe 17, the geothermal heat recovery pipe 23, and the geothermal heat recovery pipe 28 in the four corners of the foundation floor 52 below the first floor, so that each other's geothermal heat recovery The distance between the pipes is increased, and it becomes possible to reduce the interference of heat from the underground heat recovery pipes due to the heat generated from the underground heat recovery pipes in the underground. In particular, when a large number of underground heat recovery pipes are buried in a narrow site, the underground temperature changes due to the underground heat that is dissipated (recovered) into the ground by the underground heat recovery pipes. The benefits of recovery are reduced.

  In this way, by installing a single blower to each of the underground heat recovery pipe 13, the underground heat recovery pipe 17, the underground heat recovery pipe 23, and the underground heat recovery pipe 28 to recover the underground heat. It is possible to efficiently recover the underground heat. 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 17, the underground heat recovery pipe 23, and the underground heat recovery pipe 28. However, if it is too cold (warm) at the beginning of summer (winter), several of the four geothermal heat recovery pipes are moved, and the other geothermal heat recovery pipes are stopped. This makes it possible to adjust the temperature inside the first floor.

  In addition, in the foundation part under the first floor of a general house, in particular, in the solid foundation (cloth foundation), in order to prevent moisture in the lower part of the first floor, the outside has good ventilation, but in the present invention, the first floor In order to use the inside of the underfloor as an outside air temperature control tank, the inside of the first floor is configured to be sealed so that the outside air does not flow directly into the lower part of the first floor.

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

  First, a method for supplying air (fresh air) supplied from the total heat exchange type ventilation fan 64 and the total heat exchange type ventilation fan 65 to the indoor side to the first floor 104 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 65 and exhausted to the outside. At that time, the indoor air exhausted by the total heat exchanging ventilator 65 (indoor discharge air) and the outside air supplied to the room (outdoor intake air) are heat-exchanged inside the total heat exchanging ventilator 65. At the same time, all of the sucked outdoor outside sucked air (fresh air) is guided to the first floor under floor 104 via the air supply introduction duct 66. Similarly, the indoor side discharged air (contaminated room air) in the second floor room B is sucked into the total heat exchange type ventilation fan 64 and exhausted outside the room. At that time, the indoor air exhausted by the total heat exchange type ventilation fan 64 (indoor discharge air) and the outside air supplied into the room (outdoor suction air) are heat-exchanged in the total heat exchange type ventilation fan 64. At the same time, all of the sucked outdoor intake air (fresh air) is guided to the first floor floor 104 via the air supply introduction duct 67.

  In this way, by using the total heat exchange type ventilation fan 64 and the total heat exchange type ventilation fan 65, when the cool room air in the summer is replaced (ventilated) with the hot outdoor air, It is possible to minimize the temperature rise.

  Subsequently, how the outside air (outdoor air intake air) from the total heat exchange type ventilation fan 64 and the total heat exchange type ventilation fan 65 introduced into the first floor under floor 104 in this way exchanges heat in the first floor under floor 104. Explain how the wind will be weak. The outside air from the supply air introduction duct 66, the total heat exchange type ventilation fan 64 introduced from the supply air introduction duct 67, and the total heat exchange type ventilation fan 65 is mixed with the air under the first floor 104, and enters the underground heat recovery pipe 71. By operating the attached blower 72, the air under the first floor 104 is sucked into the underground heat recovery pipe 71 from the direction of the arrow 70 and is cooled by the underground heat in the underground heat recovery pipe 71 and weakened. It becomes cold air and is exhausted from the blower 72 to the lower first floor 104 as shown in the direction of the arrow 73. Similarly, by operating the blower 77 attached to the underground heat recovery pipe 75, the air under the first floor 104 is sucked into the underground heat recovery pipe 75 from the direction of the arrow 74, and the underground heat recovery pipe 75 The air is cooled by underground heat and becomes weak cold air, and is exhausted from the blower 77 to the lower first floor 104 as indicated by an arrow 78 direction. Similarly, by operating the blower 80 attached to the underground heat recovery pipe 76, the air under the first floor 104 is sucked into the underground heat recovery pipe 76 from the direction of the arrow 79, and the ground heat recovery pipe 76 It is cooled by underground heat and becomes weak cold air, and is exhausted from the blower 80 to the lower first floor 104 as indicated by the arrow 81 direction. Similarly, by operating the blower 84 attached to the underground heat recovery pipe 83, the air under the first floor 104 is sucked into the underground heat recovery pipe 83 from the direction of the arrow 82, and the ground heat recovery pipe 83 The air is cooled by underground heat and becomes weak cold air, and is exhausted from the blower 84 to the first floor floor 104 as indicated by the arrow 85 direction.

  In this way, the outside air that has become weak air in the first floor 104 under the first floor cools the first floor room A by cooling the first floor, and the air in the first floor 104 under the first floor is supplied with air. By operating the blower 110 attached to the duct 119, the air is supplied to the first floor ceiling 100 via the air supply duct 119, and is supplied to the first floor room A from the gallery 106 and the gallery 108 to be supplied to the first floor room. Cool A. Similarly, by operating the air blower 115 attached to the air supply duct 111, the outside air that has become weak air in the first floor under floor 104 is supplied to the second floor ceiling 116 via the air supply duct 111. The second floor room B is supplied from the gallery 113 and the gallery 118 to cool the second floor room B.

  In the summer, the remaining hot water of the bath 97 is not supplied to the hot water heat storage tank 102 installed under the first floor 104, and the hot water heat storage tank 102 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 (fresh air) supplied from the total heat exchange type ventilation fan 64 and the total heat exchange type ventilation fan 65 to the indoor side to the first floor 104 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 65 and exhausted to the outside. At that time, indoor air exhausted by the total heat exchange type exhaust fan 65 (indoor discharge air) and outdoor air supplied to the room (outdoor intake air) are heat-exchanged in the total heat exchange type exhaust fan 65. At the same time, all of the sucked outdoor outdoor air (fresh air) is guided to the first floor floor 104 via the air supply introduction duct 66. Similarly, the indoor side discharged air (contaminated room air) in the second floor room B is sucked into the total heat exchange type ventilation fan 64 and exhausted outside the room. At that time, the indoor air exhausted by the total heat exchange type ventilation fan 64 (indoor discharge air) and the outside air supplied into the room (outdoor suction air) are heat-exchanged in the total heat exchange type ventilation fan 64. At the same time, all of the sucked outdoor intake air (fresh air) is guided to the first floor floor 104 via the air supply introduction duct 67.

  Thus, by using the total heat exchange type ventilation fan 64 and the total heat exchange type ventilation fan 65, 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 (outdoor air intake air) from the total heat exchange type ventilation fan 64 and the total heat exchange type ventilation fan 65 introduced into the first floor under floor 104 in this way exchanges heat in the first floor under floor 104. Explain how the wind becomes weak. The outside air from the supply air introduction duct 66, the total heat exchange type ventilation fan 64 introduced from the supply air introduction duct 67, and the total heat exchange type ventilation fan 65 is mixed with the air under the first floor 104, and enters the underground heat recovery pipe 71. By operating the attached blower 72, the air under the first floor 104 is sucked into the underground heat recovery pipe 71 from the direction of the arrow 70, and is warmed by the underground heat in the underground heat recovery pipe 71 and weakened. It becomes warm air and is exhausted from the blower 72 to the lower first floor 104 as shown in the direction of the arrow 73. Similarly, by operating the blower 77 attached to the underground heat recovery pipe 75, the air under the first floor 104 is sucked into the underground heat recovery pipe 75 from the direction of the arrow 74, and the underground heat recovery pipe 75 Inside, it is warmed by underground heat to become weakly warm air, and is exhausted from the blower 77 to the lower first floor 104 as indicated by the arrow 78 direction. Similarly, by operating the blower 80 attached to the underground heat recovery pipe 76, the air under the first floor 104 is sucked into the underground heat recovery pipe 76 from the direction of the arrow 79, and the ground heat recovery pipe 76 Inside, it is warmed by underground heat to become weakly warm air, and is exhausted from the blower 80 to the first floor floor 104 as indicated by the arrow 81 direction. Similarly, by operating the blower 84 attached to the underground heat recovery pipe 83, the air under the first floor 104 is sucked into the underground heat recovery pipe 83 from the direction of the arrow 82, and the ground heat recovery pipe 83 Inside, it is warmed by underground heat to become weakly warm air, and is exhausted from the blower 84 to the lower first floor 104 as indicated by the arrow 85 direction.

  Furthermore, in the winter, the natural refrigerant heat pump water heater (EcoCute) 122 is moved with electricity generated by the solar panel 63 to store hot water in the hot water storage tank 93, and from the hot water storage tank 93 to the bath 97 via the hot water supply pipe 91. The hot remaining hot water after being supplied with hot water and being used in the bath 97 is removed via a remaining hot water pipe 96 by removing a drain plug (not shown) for the remaining hot water pipe 96 provided in the bath 97. The hot water is poured into the hot water storage tank 102 and stored. The hot water remaining in the warm bath 97 stored in the hot water heat storage tank 102 in this way warms the air under the first floor 104. In addition, the remaining hot water in the cooled bath at the bottom of the hot water storage tank 102 overflowing from the hot water storage tank 102 flows in the direction of the arrow 131 through the drain pipe 86 and is drained into the drain groove 87.

  The hot water stored in the hot water storage tank 93 by moving the natural refrigerant heat pump water heater (EcoCute) 122 with electricity generated by the solar battery panel 63 in this way is used in the bath 97 and further used in the bath 97. The hot remaining hot water is poured into the hot water heat storage tank 102 installed on the foundation bottom of the first floor floor 104 to store hot water, so that the underground heat recovery pipe 71, the underground heat recovery pipe 75, the underground heat recovery pipe 76, The air in the first floor under floor 104 heated by the underground heat in the underground heat recovery pipe 83 is further heated by the hot water stored in the hot water heat storage tank 102 to become a low temperature air.

  In this way, the outside air that has become the low temperature air under the first floor 104 warms the first floor room A by heating the first floor, and the air in the first floor under 104 that has become the low temperature air is supplied. By operating the blower 110 attached to the duct 119, the air is supplied to the first floor ceiling 100 via the air supply duct 119 and supplied to the first floor room A from the gallery 106 and the gallery 108, and is then supplied to the first floor room A. Warm up. Similarly, by operating the blower 115 attached to the air supply duct 111, the air is supplied to the second floor ceiling 116 through the air supply duct 111, and is supplied to the second floor room B from the gallery 113 and the gallery 118. The room B on the second floor is warmed.

  In this way, in the winter, after using the hot water stored in the hot water storage tank 93 by moving the natural refrigerant heat pump water heater (EcoCute) 122 with the electricity generated by the solar panel 63, the hot water stored in the hot water tank 93 is used in the bath 97. The hot remaining hot water after being used in the bath 97 even if it is cloudy or rainy, by flowing it into the hot water heat storage tank 102 installed on the base floor of the floor 104 under the first floor, and keeping it hot. By flowing hot water into the hot water heat storage tank 102 and storing the hot water, it is warmed by the underground heat in the underground heat recovery pipe 71, the underground heat recovery pipe 75, the underground heat recovery pipe 76, and the underground heat recovery pipe 83. The air under the first floor 104 can be further warmed and supplied to the first floor room A and the second floor room B as weakly warm air.

  FIG. 5 illustrates the flow of air in the hot water heat storage tank 169, the underground heat recovery pipe, the blower, and the first floor underfloor space installed on the foundation bottom 150.

  Outside the foundation heat insulating material 152 is constructed around the building foundation 151, and four underground heat recovery pipes are arranged at the four corners of the foundation bottom base 150 of the building. The hot water storage tank 169 is installed on the top of a heat insulating mat 177 (using thick foamed polystyrene) installed in the center of the foundation bottom board 150, and the hot remaining hot water after being used in the bath is taken from the bath (not shown). The remaining hot water pipe 173 is passed through the intake 172 to the hot water heat storage tank 169 to be stored. In addition, the remaining hot water in the cooled bath at the bottom of the hot water heat storage tank 169 overflowing from the hot water heat storage tank 169 is drained from the drain port 175 to the drain groove 158 via the drain pipe 174.

  Next, the function of the hot water heat storage tank 169 will be 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 169. The hot water heat storage tank 169 is configured in a water pillow shape by welding the end portions of two rubber-like sheets (vinyl chloride sheet or the like) cut into a rectangle. The upper surface rubber sheet 180 used in the upper part of the hot water heat storage tank 169 has holes (not shown) for the intake port 172 and the drain port 175, and the rubber sheet is cut into a square shape (about 20 cm × about 25 cm). A welded portion 171 having a hole (not shown) for a remaining bath of hot water in the center is created, and the welded portion 171 has an intake 172 made of a PVC pipe. Similarly, a welded portion 176 in which a rubber-like sheet is cut into a quadrangular shape (about 20 cm × about 25 cm in size) and a hole (not shown) for a drain outlet is formed in the center portion while being welded with vinyl chloride. A drain outlet 175 made of a PVC pipe is welded to the welded portion 176 by vinyl chloride welding, and the welded portion 171 and the welded portion 176 are welded in accordance with a hole position (not shown) formed in the upper rubber sheet 180. 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. Water is also stored by processing into a waterproof sheet, and even when a hot water heat storage tank like the present invention is made of a rubber sheet, water retention performance and durability can be maintained for a long time.

  When the remaining hot water of the bath flows into the hot water storage tank interior 189 from the intake port 172 thus attached, the remaining hot water of the bath flows from the intake port 172 to the welded portion 171 as shown in the BB sectional view. As shown by the direction of the arrow 188 via the fixing portion 187 attached immediately below, the hot water storage tank interior 189 flows into the hot water storage tank interior 189, and the hot water remaining in the hot bath is stored on the upper side of the hot water storage tank interior 189. When the remaining hot water is supplied to the hot water heat storage tank interior 189 in this way, the upper part of the hot water heat storage tank interior 189 is kept warm, and the lower part of the hot water heat storage tank interior 189 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 189 is sucked in the direction of the arrow 190 from the drainage intake port 191 at the bottom of the hot water storage tank interior 189, as shown in the AA sectional view, The water is drained from the drain port 175 via the drain pipe 192. Note that the height of the inlet 172 attached to the hot water heat storage tank 169 into which the remaining hot water of the bath flows and the height of the outlet of the drain outlet 175 from which the remaining hot water of the cold bath is discharged from the hot water heat storage tank 169 are Since the heat storage tank 169 is made of a rubber sheet, the remaining hot water in the bath flows into the hot water heat storage tank 169, so that the hot water heat storage tank 169 swells in the shape of a water pillow. In the state where the water is poured until the tank is full, the upper part of the upper surface rubber sheet 180 of the hot water heat storage tank 169 is higher than the uppermost part (may be about 10 to 20 centimeters higher than the upper part of the upper surface rubber sheet 180). Must be configured to be

  By configuring the hot water heat storage tank 169 in this way, the hot water remaining in the hot bath is supplied to the hot water heat storage tank 169 every day, and even when rainy or cloudy days continue, the air inside the floor under the first floor can be heated. It becomes. Furthermore, since the drainage inlet 191 is installed at the bottom of the hot water storage tank interior 189, the hot water accumulated in the bottom of the hot water storage tank interior 189 is included in the remaining hot water of the bath with the remaining hot water of the cold bath. It can be easily discharged together.

  Next, with reference to FIG. 7, the installation location and function for installing the ceiling-mounting total heat exchange type ventilation fan 229 will be described.

  As shown in FIG. 7 b, the ceiling-mounted total heat exchange type exhaust fan 229 has an indoor air intake 228 provided on the lower surface of the ceiling-mounted dedicated total heat exchange type exhaust fan body 223, and is sucked from the indoor air intake 228. The indoor air thus exhausted is exhausted in the direction of the exhaust 226 (outdoor) indicated by an arrow using one exhaust pipe 227, and the exhausted indoor air is hood 203, hood 205 as shown in FIG. 7a. The indoor air exhausted by the ceiling-mounted total heat exchange type exhaust fan (indoor exhaust air) and the hood 203 and the hood 205 are sucked from the hood 203 and the hood 205 and then passed through the outdoor air intake pipe 224. The outside air 225 sucked into the ceiling-mounting type total heat exchange type ventilation fan 229 is heat-exchanged inside the ceiling-mounting type total heat exchange type ventilation fan body 223, and the sucked outside air 225 is It is configured to be air supply 230 branches into several air supply pipe 231 to each room.

By operating the ceiling-mounting total heat exchange type ventilation fan 211, the indoor air in each room flows into the corridor G from the direction of the arrow 213, and is sucked into the ceiling-mounting type total heat exchange type ventilation fan 211. Air is heat-exchanged with fresh outside air inside the ceiling-mounted total heat exchange type exhaust fan 211, and all the air is supplied to the first floor under floor 234 through the air supply introduction duct 233. Similarly, the ceiling-mounting total heat exchange type ventilation fan 207 is attached to the ceiling portion of the corridor D on the second floor, and the ceiling-mounting type total heat exchange type ventilation fan 207 is operated. It flows into the corridor D from the direction, and is sucked into the ceiling-mounted total heat exchange type ventilation fan 207, and the sucked indoor air is heat-exchanged with fresh outside air inside the ceiling-mounted type total heat exchange type ventilation fan 207. The supply air is supplied to the first floor under floor 234 via the supply air introduction duct 220. The fresh outside air supplied to the first floor underfloor 234 in this way passes through the air supply duct from the first floor underfloor 234 to the first floor under the ceiling and the second floor under the ceiling as described in FIGS. Air is supplied and supplied to the living room from the gallery in each room. In this way, by installing one ceiling-mounted total heat exchange type exhaust fan in the hallway on each floor, it is possible not only to adjust the room temperature of the entire building, but also to the hallway as well as the living room. The cleaning work can be easily performed because only one floor is required to be cleaned.

  FIG. 8 shows a state in which the house 236 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 237 (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 239 (generally, foamed urethane having a thickness of 75 mm) is applied to the inside of the outer wall. As for the window sash, a heat insulation sash 240 of heat insulation class 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 241 (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 a general next-generation energy saving type house, a heat insulating material is installed below the first floor, on the first floor, behind the second floor, and on the second floor. In order to keep the temperatures as uniform as possible, heat insulating material is not applied to the first floor under floor 244, the first floor ceiling 243, and the second floor ceiling 242.
