[0003]

[Problems to be solved by the invention]

 The technology described in the prior art has the following problems. A. In the heat insulation and airtightness of the floor surface, it was difficult to perform sufficient airtight work due to the penetration of the equipment piping. Regarding moisture proofing under the floor, the moisture proofing measures using polyfilm and underfloor ventilation were not sufficient, and it was common to see that the foundation and the daiki were decayed. B. As for heating, individual heating using a stove or the like may cause a temperature difference between rooms, and a large temperature drop occurs in non-heated rooms such as entrances, toilets, bathrooms, or rooms without heaters. In addition, the installation cost of the centralized heating system is high, and the equipment specifications of the commercially available equipment are excessively large due to the remarkable improvement of the insulation and airtight performance of the house. C. Heating panels or individual heating stoves that constitute a centralized heating system require considerable space for installation. D. Heat loss from the foundation and underfloor ventilation cannot be ignored. E. FIG. Regarding ventilation, correct ventilation cannot be secured at the ventilation openings provided directly in each room. In addition, short-circuiting is likely to occur with ventilation fans that supply and exhaust air at the same time, making it difficult to properly ventilate the entire room. F. In the case of the motorized centralized ventilation system, the performance of the equipment affects the overall ventilation volume, resulting in improper ventilation due to improper installation work or reduced equipment performance. In the event of a power outage or failure, ventilation is not performed at all.

[0004] The present invention has been made in view of such problems of the conventional technology, and has as its object to provide a solution that can solve the following problems. 1. The present invention does not require energy for ventilation, and uses the energy used for heating to perform planned ventilation. The objectives are firstly to improve indoor air quality and secondly to save energy. Promotion. 2. Regarding the ventilation method, a heater is placed in the underfloor space, and at the same time, fresh air from the outside is taken in, so that the underfloor space serves as a space and a chamber for heating. 3. The fresh air warmed in this chamber is distributed to each room through the outlet gallery (to the second floor, above the ceiling on the first floor (below the second floor) through a passage provided in a specially-designed partition wall. Fresh air is raised and distributed from this chamber to each room through the outlet gallery, and the air that has passed through each room is discharged to the outside through an exhaust pipe provided on the second floor ceiling as contaminated air. Become. During this time, no energy such as a ventilation fan is required to move the air. 4. As for heating, each room can be heated evenly by warming the floors on the first and second floors. On the warmed floor surface, an updraft is generated over the entire surface, and this updraft agitates the indoor air and discharges it without stagnant air. 5. The ascending air current generated indoors enables the prevention of falling mold growth and the suppression of mite propagation, and extremely naturally and effectively discharges VOCs (volatile organic compounds) such as formaldehyde generated indoors. This will make it possible to create a truly healthy home and create a comfortable and safe living space.

[0005] 6. The highly airtight construction method and the underfloor heating system further promote the drying of hidden parts such as underfloor to suppress decay of structural materials, etc. Has become a major factor. 7. Selection of Underfloor Heater The basic philosophy of this method is that fresh air 10 supplied from the outside is designed to circulate and convect in the room 4C, and in order to realize the basic philosophy, it is placed under the floor. It is desirable that the heater 7 to be used adopts a convection type. 8. Improvement of air supply and exhaust stack A. In order to prevent dust, insects, and other foreign matter from entering from the outside air suction port 6B, a stainless wire mesh of 0.4 × 8 × 8 mm is attached to the inlet, or a filter 6B1 made of non-woven fabric is attached. B. At the top of the vertical exhaust cylinder, a stainless steel wire mesh of 0.4 x 8 x 8 mm is attached as bird protection net 8B. C. Use a silencer 8E such as a glass wool pipe or attach a silencer in the exhaust pipe to prevent wind noise in strong winds. D. In preparation for intrusion of rainwater, powdered snow, etc. from the top of the vertical exhaust stack, a drain 8C is attached to the bottom of the vertical exhaust stack to enable constant drainage. 9. For smooth air convection in the room, the first floor is circulated from below the floor through the outlet gallery 3A provided on the floor of the first floor, and the second floor is heated to the second floor below the first floor partition wall 4C3. Fresh air is introduced and circulated from the outlet gallery 4C22 provided on the floor of each room on the second floor. At this time, the circulation effect is enhanced by installing the heater 7 directly below the partition wall.

【Example】

 A. Underfloor is used as a heat supply room, and underfloor soil is formed.In order to enhance the heat storage effect, a 0.2 mm polyfilm is laid to prevent heat from rising from the soil. It is constructed by installing reinforced concrete with a thickness of about 100 mm. B. In order to bring the entire underfloor closer to a heat supply chamber without uneven temperature, measures were taken to eliminate the factors that impede airflow and create air pockets. a. Intermediate partition foundations were basically abolished and limited to the minimum ones, the size was reduced to 105 mm square, and the lack of strength was compensated for by a bundle 3C such as a plastic adjustment bundle. b. It is desirable to abolish floor insulation and use a single-layer structure such as thick structural plywood for flooring, and to abolish the floor joist structure. C. Convection type heaters, such as hot water panel heaters, are installed at appropriate positions so that the radix will not be uneven.

D. For ventilation, pipe 6A with a diameter of about 150 mm It is configured to start up under the floor via the underground of L1000mm (the geothermal temperature is higher than the outside air temperature in winter) and to blow fresh outside air from the underfloor fresh air inlet 6C. E. FIG. Fresh air discharged from the underfloor fresh air inlet 6C is heated and heated by a heater. In this case, a so-called underfloor ventilation port is not required and is not provided. The thus-obtained freshly heated air under the floor, which is substantially uniformly distributed, is gently blown out from the blow-off opening arbitrarily arranged on the floor plate portion 3 as an ascending airflow to warm the entire room by convection. F. The ascending airflow that has finished heating and heating the room is discharged from the vertical exhaust cylinder 8A that has been set up near the center of the building on the roof. The height of the vertical exhaust pipe 8A is set so as to provide a pressure difference enough to smoothly perform natural ventilation. It is 9000 mm or more from L. G. FIG. The vertical exhaust pipe 8A is covered with an exhaust pipe top cover 8A1 to prevent the entry of rainwater, powdery snow, and the like, as well as the effect of the wind speed. As a result, natural ventilation of the entire room is ensured, and no other indoor ventilation holes are required.

[0012]

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained. A. According to the present invention, there is no need for special equipment on the floor, and it is possible to obtain a comfortable environment where there is little difference between indoor and outdoor temperatures, as well as comfortable and well-established floor heating, and a warm feeling under the feet. The total equipment cost for central heating and ventilation is greatly reduced. B. Since it is not heat supply and ventilation with mechanical power, there is no need for running inspections and running power. C. Since ventilation is performed efficiently, indoor moisture and contaminated air are discharged to the outside, preventing dew condensation, suppressing the generation of mold, and preventing VOCs (volatile organic compounds) from staying. D. Since there is no air vent, there is no need to consider heat loss from the air vent. E. FIG. As a secondary effect, there is no heating device such as a heater or stove on the floor, so the indoor space can be widely used. As a result, there is no restriction on the layout of the floor plan or furniture. F. A relatively large underfloor space can be used effectively. G. FIG. Powered ventilation fans are not used for air movement for ventilation, and heating efficiency is high due to underfloor heating, which saves energy in houses. H. Since the underfloor dries, no structural material such as foundations and sashes rot, so the life of the building can be extended.
