[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating / cooling system for a building, which makes it possible to economically cool and / or heat the interior of a building. Forcibly circulate air with a relatively inexpensive blower fan etc. in the indoor enclosed cavity sealed between

[0002]

2. Description of the Related Art In Japan, many houses to be constructed are designed to be comfortable in summer, cool in winter, and comfortable.
Filling the cavity formed between the interior wall and the exterior wall of the building, or the insulating part such as glass wool, rock wool, or urethane foam in the back of the structural part surrounding the room, such as under the floor or on the ceiling, or the back of the finished part The mainstream is the construction of a heat insulation structure that is attached to increase the heat insulation effect around the room. Recently, a structure that blocks the ventilation state to the outside as much as possible has been realized, so-called high airtightness, high airtightness. Although insulated houses are attracting attention, it is practically difficult to realize a completely closed structure, not only with the former heat-insulated construction, but also with the recent highly airtight and highly heat-insulated construction. Insulation materials with high hygroscopic properties, due to the dew condensation phenomenon that can not be completely prevented due to the difference in temperature between the inside and outside, will become absolutely hygroscopic over the years, damaging the surrounding building materials,
They tend to shorten the lifespan of buildings, for example by inducing termites.

In order to improve the harmful effects of the heat insulating material in the wall surface, the heat insulating material is not put in the hollow portion in the wall surface, but the air having an extremely low heat transfer coefficient existing in the hollow portion is used. There have been proposals for air cycle systems that increase the power. In systems built with this system, for example, in the summer, the air in the cavity on the south side wall is opened through the attic by releasing the exhaust vent above the ceiling to release heat from the illuminated sunlight and release it through the attic. The natural air convection on the south side wall through the floor below the floor, and the natural air convection on the north side to each room, lower the indoor temperature than usual, cooling In winter, the exhaust vent above the ceiling is closed, and in the cavity on the south side wall, the air that has absorbed solar heat is collected in the building, and natural convection flows to every corner in winter. In addition, the heating efficiency is enhanced by arranging the warm air to circulate into the room.

[0004] Certainly, recent homes have become much more excellent in the heat insulation function than the conventional wall structures due to the improvement and progress of their structural forms and building materials. Regardless of whether the air conditioning is a central control system or a separate system for each room, the required amount of heat calories can be greatly reduced in total amount, and it can be maintained and managed quite economically. There is no difference, but in the era of enjoying a rich life, even those living in improved homes with high-security, high-insulation structures will have a luxurious sense of temperature. Or the fact that light clothing is becoming more common, it is not always possible to obtain a satisfactory cooling and heating effect.
In many cases, a hot carpet or a kotatsu is used as a local heating device in a plurality of heating systems or devices. In other words, even when adopting a structure that enhances the heat insulation effect in the wall of the building, all of these are only to assist the cooling and heating effect by shielding the room as much as possible from the climate outside the building, As a result, the cost of cooling and heating is not much different from that of the past.

[0005] Such a phenomenon is substantially the same in the building of the other air cycle. Further, this system has a structure in which heat is exchanged while partially taking in outside air, and air is circulated in all rooms. This leaves the fatal problem of not being able to achieve the expected heating and cooling effects, and also results in a structure in which each room is connected by the cavity in the wall, resulting in walking in the room and opening and closing the door. Street sounds, operating sounds of household appliances, sounds and voices such as music and conversation reverberate through these cavities, and are transmitted to other rooms as unexpectedly loud noises. Smoke and harmful gases easily flow into other rooms, making it difficult to secure a comfortable living environment, and have another problem. But in fact That.

The inventor of the present application has focused on the necessity of solving the many problems that occur in such conventional high heat insulation, high airtight houses and buildings having an air cycle function. In particular, we have begun development and research on a simple cooling and heating system that can be easily adopted in ordinary homes, and have already started to use our home fan heater to efficiently heat each room on the first floor of a building. A complete heating system has been completed, and the application has been filed as the invention of Japanese Patent Application No. 157489 in 1996. The present invention has been repeated trial and error and many trial production experiments in order to apply and develop the technical idea of the heating system filed as described above. The heating and cooling system and the heating and cooling device for it were completed and realized. In the following, the configuration will be described in detail with some embodiments representative of the present invention shown in the drawings.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As will be clearly understood from the embodiments of the present invention shown in the drawings, the heating and cooling system for a building included in the present invention basically has the following configuration. I have. That is, each wall surface such as a window opening on the outer wall, an entrance / exit portion leading to a corridor or an adjacent room, a ventilation opening for discharging indoor air to the outside of the building, and an underfloor storage portion formed by immersing in the underfloor space. Except for the opening formed in the interior, each surface of the room consisting of the wall surface, floor surface, ceiling surface, and the outer wall of the building formed opposite to each surface of the room, as well as vertically and horizontally adjacent The walls, floors, or concrete floors and ceilings of the rooms are almost airtight so that air does not flow between the outside of the building and the inside of the room. A lower-floor underfloor space forming a part of the indoor enclosing cavity, forming an indoor enclosing cavity surrounding and communicating with the indoor enclosing cavity, or at least a first-floor indoor enclosing cavity between the first-floor ceiling and the second-floor floor; The right part of the indoor surrounding cavity, which is just above the ceiling and also the attic space, A structure constructed by installing a heating device or a cooling device in the lowermost space that is a part of the indoor surrounding cavity while communicating with an air guide tube having a forced air blower incorporated in a part and / or a halfway part Heating and cooling system.

More specifically, the mutually facing surfaces of the building material forming the floor, wall and ceiling of the room and the building material forming the outer wall of the building, that is, the portion facing the indoor surrounding cavity. All, or, if necessary, for all building materials, including structural members in the room surrounding cavity, to attach an airtight sheet or film, or to form an airtight coating film layer, The interior surrounding cavity formed between the outside of the building and the interior side is configured to be almost airtight, and the lowest floor underfloor space which is a part of the interior surrounding cavity, and at least the first floor ceiling Air in which a forced air blower is incorporated at the end and / or midway of the room surrounding cavity portion between the first floor and the second floor, or the room surrounding cavity portion right above the first floor ceiling and also serving as an attic space. While communicating with the guide tube, The bottom space is part of, it is an heating and cooling system of the building, characterized by comprising installing a heating device or cooling device.

[0009] The building is constructed so that both walls between the outer wall and the indoor wall are airtight, and the living space is surrounded by a closed indoor surrounding cavity. It is designed not to allow any air to flow into the room.Especially for the windows, doorways, ventilation openings, underfloor storages and other openings and recesses in the room, the same applies to the corresponding indoor surrounding cavity. It must be constructed so as to prevent outside air and room air from flowing into the room surrounding cavity and from leaking air inside the cavity as much as possible.

[0010] In addition, the building has a structure that is separated from the indoor surrounding cavity and has a penetrating shape at important points of the indoor surrounding cavity, thereby allowing ventilation of the room and appropriately establishing a communication state with the outdoor. It is also possible to provide a ventilation port with a structure that can be closed, so that when using a heating device that burns kerosene etc. as local heating in each room, it is possible to take in clean air from outside. Or, hollow out the key points such as the indoor wall or the outer wall facing the indoor surrounding cavity, install the openable door, and from the same place forced air blower, heating device,
In addition, a configuration that enables maintenance and inspection of a cooling device and the like and refueling or the like can be provided side by side.

[0011] The indoor surrounding cavity is provided with an airtight sheet or film made of a lightweight material that does not easily transmit air, desirably has excellent heat insulation properties, has low hygroscopicity, and is formed on the wall surface facing the cavity. It should be of an attached hermetic structure, for example, a soft sheet made of synthetic resin, a soft resin film with a function of reflecting heat with a metal foil coating etc., a nonwoven fabric or a natural fiber material In other words, an airtight heat insulating sheet coated with a resin or the like, an airtight resin film that can be spray-painted by spraying or the like, or a paint film such as a foamed resin film with high heat insulation can be used.

The forced air blower has a function of enhancing the circulation effect by forcibly lowering the warm air and increasing the cool air separately from the phenomenon such as natural convection generated in the indoor surrounding cavity. , The upper and lower ends of the air guide cylinder, or in the middle part, or both, so as to obtain good ventilation efficiency on average over the entire room surrounding cavity, the propeller type Or screw type,
In addition to a sirocco-type blower fan, various known blowers such as a compressor and a blower pump can be used.

[0013] The air guide cylinder is configured to connect the uppermost side and the lowermost side in the indoor surrounding cavity, and the cool air which tends to accumulate downward and tends to stay at the uppermost position, and the warm air which remains moving upward. Are forcibly moving the warm and cool air to a predetermined place, respectively, to the lowermost position, and perform the function of operating the warming and cooling system more efficiently, respectively. If necessary, a special branch pipe vent that performs the function of sucking or releasing air is provided in the middle part facing the room surrounding cavity between the upper and lower floors, if necessary. It is also possible to adopt a structure having a different structure. Further, the air guide cylinder is a cylinder having a strength that is not easily deformed by receiving the blast pressure from the forced blast device, for example, a rectangular cylinder using wood, or a helical cylinder in the peripheral wall. Such as a resin pipe, a tubular soft resin sheet, or a soft resin or cloth pipe reinforced with an airtight cloth so as to maintain a cylindrical shape with a reinforcing material, or a thin steel pipe, etc. It should be formed by a metal pipe or the like.

The heating device serves to heat the air in the indoor surrounding cavity to a temperature higher than the outside air temperature. For example, the heating device includes a ceramic fan, a nichrome wire heater, an infrared lamp, a halogen heater, etc. And a radiant heater using a heat medium such as oil,
Various heating appliances such as electric heating appliances such as room air conditioners with cooling and dehumidifying functions, and stoves using firewood and charcoal, etc. can be used, but economy, handling, safety, etc. Considering the above, it can be said that a household FF oil fan heater is the most desirable heating device.

Although it depends on the type of heating device to be employed, sufficient consideration must be given to ventilation means for combustion and fireproof or fireproof structure, and nearby flammable building materials, wiring, piping, and other appliances. Should be selected where there is no such thing. In addition, since many recent heating devices are equipped with an electric operation control device, they can be controlled by actively utilizing a temperature sensor provided integrally with the main unit of the heating device, or a special external device can be used. It is desirable to appropriately perform optimal control according to the characteristics of the building structure so that a safe and economical operation of the system can be achieved by connecting sensors and the like.

The cooling device uses a room cooler supplied to various households by various home appliance manufacturers, and a room air conditioner having a heating and dehumidifying function can be used. Room cooler or room air conditioner, the indoor unit is installed in the above-mentioned indoor surrounding cavity, and the outdoor unit is installed outside the outside of the building outer wall surface, or is installed in a state embedded in the building wall surface, Provided so that the indoor unit side faces the indoor surrounding cavity, and the outdoor unit side faces the outside, and the peripheral wall surface is hermetically sealed with the building external wall surface.

[0028]

Fourth Embodiment A side sectional view of a building in FIG. 4 is a representative embodiment of the present invention in which a home room cooler is installed as a cooling device. The basic structure of the building 1 is the same as that of the first embodiment.
Since it is similar to a structure constructed by the construction method based on the conventional frame construction method already described in
The air guiding structure and the installation of the room cooler 7 will be described.

A vinyl sheet (not shown) for ensuring airtightness is adhered to all the lower ground and building materials facing the indoor surrounding cavity 3 of the building 1.
As long as the openings 13, ... are not opened, all the ventilation is shut off.
Between the lower and upper floors, the air guide cylinder 5 is formed by assembling four long rectangular wooden boards into a rectangular cylinder so as to connect the lower floor space section 31 to the attic space section 32.

[0032]

[Operation] In winter, the F of Example 1 shown in FIG.
When the F-type oil fan heater 6 is started, the intake / exhaust pipe 6a
Since the outside air is taken in and the exhaust gas after combustion is discharged to the outside of the building 1, efficient combustion can be continuously realized without polluting the air in the indoor surrounding cavity 3. A part of the warm air released into the lower floor space 31 by the combustion is guided to a position distant through the duct 62, and the warm air not flowing into the duct 62 is discharged to the left and right front of the fan heater 6. The operation is performed so that the lower-floor underfloor space 31 is filled with warm air.

On the other hand, by activating the ventilation fan 51 simultaneously with the activation of the oil fan heater 6, the cool air existing in the attic space 32 is forcibly forced through the air guide tube 5 during the warm-up of the lowest floor underfloor space 31. When the air in the room surrounding cavity 3 surrounding the rooms 15 and 16 on the first floor and the rooms 17 and 18 on the second floor is forcibly circulated, warm air rises due to normal convection, and cool air falls. It is possible to spread the warm air to the entire building 1 much more quickly than the speed at which it is performed. Surface heating by radiant heat is realized through, installation of heating equipment for each individual room, which was naturally required in the past,
Alternatively, heating that does not require a large-scale heating facility or the like that can cover all rooms is enabled.

The fuel is supplied to the oil fan heater 6 by taking out the tank of the fan heater 6 through a working hole provided on the floor of the first floor, or by using a large outdoor-installed tank installed beforehand outdoors. It is also possible to configure the piping so that the oil is supplied directly from the tank, and to supply the oil to the external tank directly from the refueling vehicle. Just look at it.

By activating the oil fan heater 6 and the ventilation fan 51 of the second embodiment shown in FIG. 2, the oil fan heater 6 takes in the air in the indoor surrounding cavity 3 and burns to emit warm air. Then, a part is guided to a remote position through the duct 62. Oxygen in the indoor surrounding cavity 3 gradually decreases due to the combustion of the fan heater 6, so that the dampers 13a, 1
In some cases, it may be necessary to open 4a and take in little fresh air. In addition, the air in the attic space 32 is forcibly sucked down by the ventilation fan 51 through the air guide tube 5 to the lowermost floor underfloor space 31 to quickly circulate warm air in the building 1, and rapidly and rapidly. Efficient heating can be performed.

Furthermore, since each of the rooms 15, to 18 is sealed in the indoor surrounding cavity 3, the combustion exhaust gas discharged by the oil fan heater 6 is prevented from flowing into the living space, and the room 15 is clean. It is possible to secure the room,
As before, the frequency of frequent ventilation can be extremely reduced due to fear of carbon monoxide poisoning, etc., and even when taking in outside air to perform indoor ventilation, radiant heat from the wall surface is damaged. Since there is no such thing, the radiant heat that works directly on the human body is sad, it is possible to reduce the time and energy waste of reheating the indoor air from the beginning like a conventional heating appliance, It is possible to obtain an extremely high energy-saving effect, and to secure an indoor environment where the room temperature can always be maintained at a certain level or higher by radiant heat from the walls including the ceiling and floor even during ventilation. it can.

In the building 1 according to the third embodiment shown in FIG. 3, by activating the oil fan heater 6 and the ventilating fan 51, the floors and peripheral walls of the rooms 15 and 16 on the first floor,
It is possible to heat the air in the indoor surrounding cavity 3 surrounding all the walls of the ceiling surface, and also to heat the underfloor space of the room 43 on the second floor, and to make each of the rooms 15, 16, and 17
Can be provided with surface heating, and by forcibly circulating the air in the indoor surrounding cavity 3,
The offset of the heating effect due to the arrangement of the rooms can be eliminated, and all the rooms can be heated substantially uniformly.

The building 1 by the two-by-four method is 1
There must be a structure in which a horizontal member is provided between the first floor and the second-floor peripheral wall portion, and the hollow portion of the second-floor peripheral wall portion becomes discontinuous to the first floor side if it is normal, and the It becomes impossible to supply warm air to the peripheral wall and ceiling of the room 17 on the floor,
Floor heating by heat from the indoor surrounding cavity 3 below the second floor is possible, and heating of all the rooms 15, 16, 17 can be realized by the single oil fan heater 6 described above. Even in the case of the building 1 by the two-by-four construction method, by providing a special bypass structure connecting the peripheral walls of the first and second floors, the peripheral wall of the room 17 on the second floor and the cavity of the attic are heated. Can also be configured to be able to supply.

The building 1 according to the fourth embodiment shown in FIG. 4 cools the air in the indoor surrounding cavity 3 by activating the room cooler 7 and the ventilation fan 51 in the summer, and all the rooms 15, 18 It is possible to cool all peripheral walls of
Due to the forced circulation of air by the ventilation fan 51, it is cooled very quickly and uniformly without unevenness.
Through the small-diameter ventilation holes (not shown) formed innumerably on the middle wall of the air guide cylinder 5 corresponding to the middle part of the floor portion,
Rooms 15 and 16 on the first floor and rooms 17 and 18 on the second floor
The air in the room surrounding cavity 3 between the room and the floor surface can also be forcibly circulated, and the cool air in the room surrounding cavity 3 shuts off the hot air outside, and the room surrounding wall 3 like a basement. In order to emit a pleasant cool air, the heat in the room is absorbed through the cooled wall surface to cool the room indirectly.

[0040]

[Effect] The heating and cooling system for a building according to the present invention having the above-described structure is not a specially equipped heating and cooling machine as in the past, but is a safe and efficient general household oil fan heater or the like. It is possible to use a room cooler as it is, and it has realized an air conditioning system that is extremely economical and easy to install in a house.
This is a wooden house, which is the standard building style of Japanese houses, and is basically used for heating and cooling systems in houses that use individual heating and cooling (even if they are highly airtight and highly insulated). This has the major feature of enabling more effective heating and cooling.

In particular, by enclosing all rooms, which are living spaces, in an airtight state with the indoor surrounding cavity,
Heat is radiated or absorbed from the floor, peripheral wall, and ceiling of the room without warm or cool air flowing into the room, so compared to the case where the room air is directly heated and cooled as before. It is possible to control the occupant's perceived temperature extremely effectively and indirectly, so that there is no worry that it will overheat or cool too much and impair health. It is possible to provide an effect, and furthermore, since each room is not communicated through the room surrounding cavity and has a structure isolated from each other, it can be used as a conventional air cycle house It can effectively prevent sound leakage to other rooms, which is often the case, and has an excellent feature of having a unique effect of providing a house with high sound insulation.

Then, rapid heating and cooling will be achieved.

Further, in the present invention, since a heating and cooling machine such as an oil fan heater and a room cooler is housed and installed in the lower floor space on the lowest floor, all operations such as refueling, maintenance and inspection, and cleaning can be easily performed. Can be done to
In addition, in conventional homes, regular chemicals are used to prevent mold and mites from causing serious health damage to residents, causing moisture on the walls and under floors to rotten pillars, and preventing the occurrence of termites. Had a lot of troubles and costs, such as the need for enormous labor and cost for spraying and examining building materials.However, during the heating system, the entire building was heated and dried to eradicate mold and ticks, The room cooler installed on the foundation during cooling can remove moisture that tends to stay inside the wall of the building 1 or under the floor, especially in the rainy season, when the concern is strong. In addition, it is possible to prevent the occurrence of termites and the like and to prolong the life of the house itself without damaging the building materials, and above all, it will be able to exert a great deal of power in managing the health of residents Effects It becomes shall.

Since the circulation of warm and cool air from a warming / cooling machine such as an oil fan heater or a room cooler is mainly performed using the indoor surrounding cavity 3, special equipment for warming / cooling is provided. It is possible to establish an extremely inexpensive forced air circulation structure by using a commercially available air guide tube made of pipe material and a ventilation fan such as a ventilation fan provided at the end of the tube. It is possible to provide an inexpensive integrated heating and cooling system for all rooms in a building, which was impossible at all if expensive piping equipment and a large heating and cooling machine were not incorporated in the structure. Therefore, it can be easily adopted in buildings such as more homes, and more people can
The effect of being able to enjoy a comfortable life in the house at a low cost throughout the four seasons is obtained.

It goes without saying that the building heating / cooling system of the present invention can of course be implemented by on-site construction. However, the wall surface, floor surface, ceiling surface, outer wall surface and roof of the building are required in advance. If the factory is manufactured as unit parts, sufficient quality control is performed, and if the interior surrounding cavity is formed by low-cost building materials, the cost of materials will be solid, The on-site construction costs can also be made significantly economical, and the above effects are further promoted.

In particular, the structure shown in the first embodiment is extremely effective in effectively realizing the heating and cooling system for a building having the above-mentioned features, and the structure of the cavity surrounding the room is extremely simple. Spread of the heating and cooling system of the present invention,
The FF oil heater 6 can be used for a long time in a completely sealed state, so that the FF type oil fan heater 6 can be used for a long time. The economy can be further improved, and according to the second and third embodiments, a basic system for heating a plurality of rooms in a house is specifically shown and one heater 6 is used. In addition, it has been proved that heating can be performed in a plurality of required rooms in a house. In Example 4, the heating and cooling system of the present invention is preferably used as in the case of heating using a general room cooler. It can be implemented in a simple cooling system, and can suppress the occurrence of illnesses such as fatigue, coldness and summer cold caused by directly blowing the cold air from the room cooler to the human body, and enjoy healthy cooling. So as to.

As described above, the heating / cooling system for a new building included in the present invention is compared with any other heating / cooling system or equipment such as an air-cycle house developed so far. It makes it possible to realize an extremely efficient and economical heating and cooling system, which is useful not only as a new strategy in the building industry, which has been prospering but also in summer and winter. People who live in the harsh climate of the country have been highly evaluated as an excellent heating and cooling system that can lead a comfortable life at a low cost. In the age of
It is expected to greatly contribute to society.
