(Point of attention)
The recent demand for housing construction is not only reflecting the economy, but also for many clients who need housing to move away from the contractor's stance until then, and the economy is solid. With a clear principle or claim in terms of structure and function, and due to the fact that we have made sufficient assessments based on these principles and claims, purchasing has also added prudence, so in the housing related industry, It is foreseen that it is impossible to persuade these owners with only the contents of the house where it makes an illusion as if a seemingly comfortable life will be realized by incorporating the previous goodness and cutting edge equipment, structural strength and economy With regard to sexuality as well as various functional measures necessary to realize a comfortable life, we are forced to review more than ever, and various developments and researches are advanced in various fields in order to realize it. It has been.

    For example, heating and cooling measures, which are one of the important factors in maintaining the comfort of a house, are midway because they are not as cold as Hokkaido, especially in Tohoku, northern Kanto, and the mountainous region of Honshu. With regard to measures to heat the winter season in areas that have been dealt with inexplicably, it is necessary to incorporate expensive equipment in addition to expensive expenses in order to achieve a high airtightness and high thermal insulation structure as in the past. Measures that introduce centralized heating and cooling and put an economic burden on maintenance costs as well as construction costs can not be said to have been able to cope with the demand under the current severe economic conditions. It is expected that building costs will be a crucial issue in housing construction in the future, especially how economical considerations will be given to solid costs, especially maintenance costs.

(Prior art)
In an effort to address these issues, although there has been a start to implement solar house incentives with public subsidies, etc., in addition to the fact that the initial investment is too expensive, there are problems with unseasonable weather during the winter. In fact, this system is not always suitable for areas that require heating, and it is not widely used, so the most practical energy sources at present in areas that require these improvements Heating system using kerosene, but local heating using traditional fan heaters and clean heaters etc., but using hot air heaters that can be obtained at extremely low cost as a heat source, Applicants and inventors of the present invention have already proposed a new type of heating system for efficient heating.

It guides part or all of the warm air from the warm air heater installed at a suitable place inside or outside the building to the warm air space prepared in advance under the floor of the room, and heats from the floor of the building That is, the realization of floor heating has been made clear with the practical application of a technology for guiding warm air from a warm air heater to a warm air space below the floor surface, for example In order to eliminate the drawback that the flowability of the warm air sent into the warm air space impedes the downward convex-concave portion under the floor surface of the air conditioner and the warm air can not be spread widely over a wide area, Patent Document 1 below “Floor heating floor assembly” which is formed by spreading a thin film material across at least the joists or the lower faces of joists corresponding to joists, which are disposed at predetermined intervals as structural members of the floor structure part of (1) Developed and limited by this Even when local heating appliances such as a fan heater or a clean heater of heat quantity are used, it becomes possible to make the warm air reach a wide area homogeneously, and a type with a conventional electric heater embedded in the floor or It has been confirmed that a much more economical and ideal heating system can be realized as compared with piping and steam type.
(1) Patent No. 3884731

(Awareness of problems)
The floor heating system technology developed by the present applicant and inventor until now homogenizes the floor heating in the winter period without being affected by the floor space of the building and the shape under the floor surface, etc. Also, it is much more economical than the type that uses low electricity consumption local heating appliances as a heat source and has a conventional electric heater embedded in the floor, or the type that passes steam through a pipe, etc. Although it was intended, if the floor surface was raised to secure the heating space above the base as before, the drawback would be that the ceiling in the room would be lowered accordingly. The characteristic that the warm air space formed by the thin film material stretched under the floor surface, which works in winter, prevents cold air existing near the ground surface below the warm air space into the room and ventilation, In the summer, it is under the floor Will not be expected to room temperature the cooling effect by heat exchange with, relying only on an air conditioner comprising conditioning in summer from the indoor unit and the outdoor unit to the previous, there is a risk that high heat costs is deteriorated.

(Object of the Invention)
Therefore, the present invention utilizes the floor heating technology in winter which has achieved excellent results until now, and realizes cooling of summer in a more economical manner, and is excellent in comfort and economy throughout the year. Judging from the judgment that new air conditioning system technology could not be developed, we started its development and research very quickly, and as a result of repeating trial and error over a long period of time and many prototypes and experiments, we are finally finally new An underfloor air-conditioning apparatus of the above structure has been successfully realized, and the configuration thereof will be described in detail below together with an example representative of the present invention shown in the drawings.

(Structure of the Invention)
As clearly understood from the representative embodiments of the present invention shown in the drawings, the underfloor air conditioner of the present invention basically comprises the following configuration.
That is, on a plurality of large pullings installed at a height above the base on the foundation rising portion of the building, a plurality of joists erected at a predetermined interval and a floor foundation plate laid on the joists A rectifying film is stretched between the lower surfaces of at least each joist and each jolt equivalent portion provided with a floor assembly having a layer set, an upper layer heat-retaining space is provided between the floor base plate lower surface and the rectifying membrane upper surface, A peripheral heat insulating wall made of a heat insulating material, which is surrounded along the inner peripheral wall from the upper surface of the ground surface below the floor set below the lower surface to any height below the upper surface of the base rise portion and the base, and the periphery A middle surface warm insulation space is provided between the lower surface of the flow control membrane and the upper surface of the upper surface heat insulation wall, and the upper surface of the ground surface and the upper surface A lower temperature control space is provided between the lower surface of the surface heat insulation wall and the upper surface In the space, a vent opening to the indoor floor base plate is provided, and to the middle layer warm air space, the warm air duct of the warm air supply device installed outside is connected, and the lower layer constant temperature space is partially the same lower layer. An above-ground duct made of a heat insulating material communicated with a constant-temperature space is circulated so as to be grounded on the ground surface immediately below the building, and an underground duct buried below the ground surface around the building. Are connected, and a constant-temperature trachea derived from the above-mentioned ground duct is connected to a room above the floor set through a suitable place at least one of a floor surface, a side wall and a ceiling wall of the same room. It becomes an underfloor air conditioner which consists of a thing made into a thing.

    As described above, according to the underfloor air-conditioning apparatus of the present invention, the upper-layer heat-retaining space under the floor assembly faces the room above the floor assembly, unlike the conventional one, from the unique characteristic configuration as described above. This will enhance the heat insulation and heat insulation of the floor surface, and warm air from the warm air supply device installed outside will spread throughout the middle layer warm air space, and warm the upper layer heat insulation space through the rectifying membrane, The floor surface of the room can be uniformly heated without any deviation to every corner, and excellent floor heating can be achieved, and the lower-layer constant-temperature space isolated from the middle-layer warm air space through the heat insulating wall. In the interior, the thermal effect of the outside air temperature is minimized, and by being exposed to the ground surface, the temperature in the summer is much lower than the outside air temperature throughout the year, and the temperature in winter is kept much warmer than the outside air temperature. Air to flow into the indoor space through the constant temperature As a result, it becomes possible to use each upper-layer heat retention space, middle-class warm air space and lower-layer constant temperature space in an integrated manner, and compared with the conventional floor heating system, air conditioning has lower fuel consumption and economical throughout the year. It is possible to obtain the remarkable effect of being able to realize

    In addition, it is possible to install in the underfloor space without raising the floor level of the room, and the upper layer heat retention space disposed in the upper floor space of the floor set and the middle floor warm air disposed in the middle position Since the straightening membrane for partitioning the space is stretched to divide the lower surface of the uneven surface of the floor assembly into a smooth surface, the warm air flowing from the warm air supply device into the middle layer warm air space is the uneven surface of the floor assembly. Effectively prevent interference with the lower surface and disturbing its flowability, and distribute warm air quickly and smoothly and uniformly throughout the entire middle-class warm air space, greatly increasing the efficiency of floor heating As a result, it is possible to operate the warm air supply device with high fuel consumption, and there is an advantage that even a smaller and smaller warm air supply device can exhibit excellent heating capability.

    Furthermore, at least the upper surface of the heat insulating wall that divides the middle layer warm air space disposed in the floor space under the floor set from the lower layer constant temperature space disposed below is made smooth. This will promote without disturbing the fluidity of the warm air flowing from the warm air supply device into the middle warm space, and realize more even floor heating, and the heat insulation wall will be a middle warm space and a lower constant temperature space. Since the space between them is highly insulated, it is possible that the ground surface can be identified in the lower-layer constant-temperature space in winter, and the thermally-affected air deprives the heat of warm air in the middle-class warm air space under heating. In the summer, air in the lower-layer constant-temperature space is heated through the upper-layer heat-retaining space and the middle-layer warm-air space from the indoor and floor surfaces that become hot due to sunlight in summer. Effectively prevent Supplying cold air cooled under the influence of thermal influence on the ground surface in the lower-layer constant-temperature space through the constant-temperature trachea into the room above the floor assembly, making the use of the air conditioner unnecessary or none, or air-conditioning The frequency of use of the aircraft and the amount of power consumption can be greatly reduced, and more economical air conditioning can be realized throughout the year.

    Then, by providing a vent opening in the indoor floor surface in the upper layer heat retention space, from the warm air flowing from the warm air supply device to the middle level warm air space, the upper layer heat retention space and the indoor floor via the rectifying film. In addition to floor heating due to heat transfer to the surface, conduction heat and radiant heat, the warm air in the upper thermal insulation space flows directly into the room from the upper thermal insulation space through the vent of the floor surface, so that the indoor space It is possible to make heating more efficient and enable more economical operation.

    Further, the heat insulating wall partitioning the lower-layer constant-temperature space is composed of a peripheral heat insulating wall made of a heat insulating material surrounding the periphery, and a top heat insulating wall made of a heat insulating material bridged between the upper ends of the peripheral heat insulating wall. According to the thing, the air in the lower-layer constant-temperature space is thermally isolated more effectively from the outside air, the heat insulation of the lower-layer constant-temperature space is greatly enhanced, the air conditioning throughout the year such as summer cooling and winter heating The economics of driving can be greatly enhanced.

    A ground duct made of a heat insulating material in a lower constant-temperature space, a part of which is in communication with the lower constant-temperature space is circulated so as to be grounded on the ground surface directly below the building. An underground duct embedded below the ground surface around the ground surface is connected, and a constant temperature air pipe derived from the above ground duct corresponds to at least a floor surface, a side wall and a ceiling wall of the room above the floor set. According to what is connected by piping through any one appropriate place, the air in the above-mentioned ground duct and underground duct is more effectively isolated from the outside air, and further more thermally above and below the ground surface The affected air can be taken into the lower constant temperature space, and the indoor air conditioning throughout the year can be made much more efficient and economical.

    An underground duct is derived from the underground duct, and a bypass pipe does not pass through the lower-layer constant-temperature space and the above-ground duct, and at least one of a floor surface, a side wall and a ceiling wall with respect to the room above the floor set. In the case where piping and connection are made through two appropriate places, the air in the underground duct can be more directly supplied into the room, and compared with cold air and warm air sent from an air conditioner etc. In addition to being able to reliably prevent overcooling and overheating without being gentle and automatic control, it is possible to achieve more effective heating and cooling savings throughout the year.

    Furthermore, in a device in which an air supply fan is disposed at at least one location of a constant temperature air tube, an underground duct, a ground air duct, a warm air air duct, and each intake and exhaust port, the blowing force of the warm air supply device or Even if it is in piping etc. where generation of rising air flow due to temperature difference of air can not be expected, forced air supply can be realized, and better air conditioning can be realized, which is more efficient.
